Зарядка аккумулятора автомобиля от блока питания компьютера в домашних условиях

Не вовремя разряженный автомобильный аккумулятор – проблема, с которой хоть единожды, но сталкивался каждый водитель. Поэтому многие автовладельцы знают, как самостоятельно собрать зарядный блок для АКБ. Даже блок питания от стационарного компьютера может стать полноценным зарядным устройством для аккумулятора, достаточно лишь приложить усилия.

Как можно зарядить автомобильный аккумулятор в домашних условиях

Аккумулятор транспортного средства устроен таким образом, что до определенного момента он может получать питание непосредственно от автомобиля. Но всем водителям известно, что чем дольше эксплуатируется устройство, тем чаще оно нуждается в дополнительной подзарядке. Поскольку генератор выдает напряжение 14,1 В, а этих значений достаточно лишь для поддержания работоспособности аккумулятора, а для полной зарядки необходимо получить напряжение 14,4 В.

Существует множество вариантов сбора самодельных зарядок, которые способны вернуть автомобиль в строй. Одни из них подразумевают использование сложных механизмов, таких как импульсивные схемы с автоматическими выключателями, другие наоборот предельно просты, и не требует глубоких знаний в сфере радиотехники.

Дома практически всегда можно найти составные части электроприборов, которые используются для сбора зарядки. Так, можно использовать компьютерный блок питания, отключенный от устройства. Его достаточно подсоединить к АКБ с помощью двух метровых проводов, которые необходимо замкнуть между собой, формируя перемычку. В качестве источника напряжения можно также использовать ЗУ от других гаджетов, которое на выходе имеет напряжение 12 В.

Второй способ подразумевает использование выпрямительного диода с обратным напряжением более 1000 В и током более 3 А. Главное, соблюдать последовательность подключения деталей, чтобы устройство не замкнуло. Так плюсовый вывод диода должен подключаться к ограничительной нагрузке, в качестве которой можно использовать обычную лампочку на 220 Вт.

Стоит помнить про опасность заряда аккумулятора напрямую от сети переменного напряжения, поэтому к такому методу стоит прибегать лишь в экстренных случаях.

Вне зависимости от вида ЗУ, при его подключении к аккумулятору, важно соблюдать полярность. В противном случае АКБ будет терять свой заряд.

Можно ли заряжать аккумулятор автомобиля блоком питания от ноутбука

В комплекте с ноутбуком идет блок питания, который с помощью дополнительных манипуляций, можно переделать в ЗУ для аккумулятора. Для заряда АКБ от блока ноутбука, следует подготовить несколько ламп накаливания, которые будут служить неким балластом цепи. Именно их горение будет говорить о том, что цепь подключена верно.

Схема цепи достаточно проста, главное, не забыть про полярность

Цепь нуждается в одном балласте, но его необходимо правильно подобрать. Поэтому важно начинать с лампы минимального наминала. Если при проверочном подключении она будет гореть, значит можно попробовать более мощный аналог. Правильным выбором станет лампа с максимально допустимым номиналом.

Схема цепи достаточно проста, главное, не забыть про полярность. Так, для получения самодельной зарядки, следует «минус» БП соединить сначала с лампой, а потом непосредственно с «минусом» АКБ. Плюсовые полюса двух устройство соединяются друг с другом напрямую, без перемычек.

Важно! Лампа накаливания является обязательным звеном цепи, поскольку без нее сопротивление будет минимальным, а это значит, что одно из устройств окончательно выйдет из строя.

Зарядное устройство для аккумулятора своими руками из блока питания

В современном мире, где каждый человек пользуется гаджетами и другой электроникой, соорудить мобильную зарядку для аккумулятора не составит труда. Некоторые автовладельцы предпочитают использовать трансформатор со старого лампового телевизора, другие берут диодную ленту. Но наиболее популярным вспомогательным средством являются БП различных гаджетов.

Главное, подобрать устройство с необходимым параметром напряжения на выходе, иначе мощности для заряда может просто не хватить. Экстремальный метод зарядки АКБ подразумевает использование розетки. Поэтому к нему стоит прибегать только в крайних случаях, когда под рукой не окажется блока питания, который бы соответствовал всем требованиям.

Для ЗУ необходимо подготовить:

1. Осветительную лампочку на 100 Вт (для сокращения периода заряда можно использовать сразу 3 последовательно соединенные лампы).
2. Выпрямительный диод, который есть в каждой энергосберегающей лампе.

Прежде чем приступать к соединению всех элементов, помещение рекомендовано обесточить.

Как и при использовании БП от гаджета, данный способ подразумевает соблюдение полярности. В ходе подключения, необходимо придерживаться следующего алгоритма:

1. «Плюс» розетки соединяем с лампочкой.
2. Подключаем диод, который должен контактировать с «плюсом» АКБ.
3. Соединяем «минуса» розетки и аккумулятора друг с другом.

Вместо лампы некоторые водители предпочитают использовать электроплиту на минимальной мощности. Но такая замена является небезопасной.

Как переделать блок питания в зарядку АКБ

Использовать БП от компьютера, в качестве основного звена самодельного зарядного устройства гораздо безопаснее прямого подключения к бытовой сети.

Необходимые материалы и инструменты

Для сбора самодельного устройства необходимо подготовить:

1. БП на микросхеме TL494 или KA7500, отсоединенный от стационарного компьютера.
2. Мультиметр.
3. Паяльник.
4. Два провода разного цвета по 1 м.
5. Нож.
6. Крестовую и плоскую отвертки.
7. Зажимы, или так называемые «крокодилы».
8. Светодиодный элемент.
9. Два конденсаторных элемента на 25 В.
10. Резисторы номиналом 2,7 и 1 кОм, 200, 68 и 0,47 Ом.
11. Диоды (2-3шт.).
12. Реле с 4 клеммами.
13. Силиконовый герметик.

Этих элементов будет достаточно для сбора ЗУ, которое сможет вернуть аккумулятор ТС к жизни за несколько часов.

Инструкция по изготовлению в домашних условиях

Чтобы собрать зарядное устройство для аккумулятора, нужно четко следовать алгоритму. Он состоит из следующих шагов:

1. Откройте системный блок, сняв крышку, которая обычно крепиться на 4 болта.
2. Отпаяйте переключатель 220/110В и все провода, которые от него отходят. Это защитит устройство от резкого скачка напряжения.
3. Уберите все провода, отходящие от микросхемы, за исключением желтого и черного пучков, а также одного зеленого провода.
4. Замените два конденсаторных элемента, расположенных на желтом проводе, на новые 25 В.
5. Удалите защиту от скачков напряжения, это поможет избежать выключения при поднятии напряжения до 14,4 В.
6. Деактивируйте средство защиты от перепадов напряжения путем замыкания 3 оптронов.
7. Увеличьте выходное напряжение до необходимых показателей с помощью дополнительной платы TL431, на которой расположен подстроечный резисторный элемент. Замените его. Сопротивление новой детали должно быть не ниже 2,7 кОм.
8. Удалите транзисторный элемент, расположенный рядом с платой.
9. Стабилизируйте выходное напряжение, подключив второй резистор с рабочей величиной сопротивления 200 Ом, при мощности 2 Вт. Резистор, который устанавливается на дополнительный канал, должен обладать параметрами 68 Ом и 0,5 Вт, соответственно.
10. Ограничьте силу тока на выходе до 8 А путем выпаивание старого резистора и его замены на новый с большим номиналом на 0,47 Ом.
11. Вмонтируйте в устройство дополнительную схему, состоящую из реле, диодных компонентов, резистора на 1 кОм и светодиода. Если последний элемент горит, значит цепь подключена верно.
12. Закрепите реле на вентиляторе блока с помощью герметика или болтов.
13. Вмонтируйте в ЗУ мультиметр путем параллельного соединения к цепи.
14. В корпусе зарядного устройства проделайте 2 отверстия для нейлоновых стяжек. Ими будут фиксироваться провода на блоке.
15. Подсоедините провода с соблюдением полярности. К аккумулятору подключение производится с помощью «крокодилов».
16. Проверьте работоспособность собранного устройства.

Процесс состоит из достаточно большого количества шагов, выполнение которых требует, как минимум, базовых знаний в радиотехнике.

Всегда следует помнить о мерах предосторожности

Как правильно зарядить АКБ самодельной зарядкой

Собирая зарядное устройство самостоятельно, всегда следует помнить о мерах предосторожности. Есть ряд правил, которые важно соблюдать при использовании зарядки, собранной в ручную. В противном случае батарея может испортиться, а вся работа будет проделана напрасно.

Основные правила:

1. Перед зарядкой аккумулятор необходимо отсоединить от автомобиля, и занести в теплое помещение.
2. Очищение устройства от загрязнений – обязательный этап его подготовки к зарядке. В качестве инструмента можно использовать наждачную бумагу с тонким абразивом или зубную щетку.
3. Электролиты в банках АКБ должны полностью покрывать металлические пластины. При недостатке жидкости можно воспользоваться обычной дистиллированной водой.
4. Устройство с глубокими трещинами или сколами заряжать нельзя.

Главное правило, которое следует соблюдать при зарядке касается полярности – «минус» всегда соединяется с «минусом». После того, как аккумулятор достаточно подзарядится, можно приступать к его подключению к автомобилю, предварительно проверив количество электролитов в банках.

Если автомобильный аккумулятор разряжен, а специальное зарядное устройство отсутствует, его можно сделать самостоятельно. Но для этого необходимо иметь не только знания в радиотехнике, но и опыт работы со схемами электрической цепи.

Among them, the most common options are: — 90003 90006 90007 Charge laptop with US B 90008 90007 Charge laptop using phone 90008 90007 Charge laptop battery externally 90008 90007 Charge laptop in a car (using cigarette lighter + inverter) 90008 90015 90002 However, you can carry a portable Laptop Power Bank to charge whenever needed.90003 90002 If you want to get one, I recommend Jackery PowerBar. It is good unit for emergency and multiple charging needs.It can power about 99% on my 15 «HP laptop. It also can power my iPhone and iPad, even the desk lamp. 90003 90002 90021 How to charge laptops with USB 90022 90003 90002 One of the most important accessories of laptops includes chargers. Laptops are charged by the power source connected to these chargers. 90003 90002 However, with the innovation in technology new ways are ought to be developed for charging laptops other than chargers.One of the emerging methods is charging the laptop by USB port. It is the same as charging the mobile phone with the power bank. However, the case with laptops is that they have many ports and all of these ports can not be used for charging purposes. These ports are utilized to give power to other devices such as mobile phones or to transfer data between devices. 90003 90002 Most recently Type B and Type C ports are introduced in the laptops which allow charging of laptops through USB cable. Power banks are used for delivering power to the laptops through USB- Type C.The power bank should have the capability to deliver the required power between 60W-100W at 20V voltage supply for current laptops. If the rated voltage of power bank is less than the laptops rated voltage, it will not be of any use. So, along with type-C USB charger, the rated voltage of power source also matters a lot. 90003 90002 For charging laptops suing HDMI, we need to use an adopter for connecting C-Type USB and HDMI cable for charging the laptop. Type-C ports are very common in mobile phones too.So, we can charge a laptop by connecting its C-type port with the mobile phones C-type port through a data cable. Although the power supplied would not be that high, but it can help in critical times. 90003 90002 To avoid any urgency or to spoil your mood over your lost charger while you are traveling, buy a laptop that has at least one type-C port. And with the interests in USB4, its obvious that USB-C will remain a standard for the coming years. 90003 90002 90035 How to charge laptop battery externally? 90022 90003 90002 Laptop is considered as backbone of the computer users.It provides a convenient and quick way to check documents, editing and many other facilities. But all these benefits and convenience come with few challenges. One of the challenges is to charge laptop. It become more challenging if you can not recharge your laptop battery after running out of power. It can be caused by a plethora of factors. For instance, the Power port of laptop may be damaged or might detach from power source etc. 90003 90002 One of the solutions for the user to carry multiple batteries but its not possible all the time.So there is need for another method to charge Laptop battery. Charging Laptop externally is another solution. We can charge our laptop battery externally by using Three methods. 90003 90002 First step is to check if the AC adapter is available in your laptop battery, if yes, then directly connect charger to the adapter port of laptop battery to charge It manually. 90003 90002 Second method is to get an external battery charger according to your laptop model compatibility. Because batteries are manufactured with different specifications for different machines.So always check external charger specifications. 90003 90002 Third method is buying an extra battery according to your laptop specifications. Before buying, make sure that the battery is equipped with the AC adapter port. You can recharge the backup battery externally while using the old battery running out of power without effecting your important tasks. 90003 90002 Once old battery is out of charge replace with externally charged battery and continue your work. Another solution is to carry two laptops and keep charging them one by one while using charged one, but this method is not going to work if you do not have power source, then power banks can help.90003 90002 To use power banks efficiently, you need to consider the specifications of your laptop battery and the AC adaptor option in your laptop battery. 90003 90002 So you should check for the one that matches your laptop specifications. 90003 90002 If you do not know how to do it, read my post on how to check laptop specs windows 10.With this, Spare battery can comfortably be charged without the need to switch off the laptop. 90003 90002 90057 How to charge a laptop using phone 90022 90003 90002 Loosing charge on a phone battery is highly irritating but now due to advanced technologies we have power banks that does its job well.What’s more frustrating is when you have to work on a project just to see that the laptop battery is about to die with no chargeable ports nearby. Or maybe you are not at home and have forgotten your laptop charger. 90003 90002 We know about charging out phone with our laptop. How about an inversed case? How about charging our laptop with our phones? Yes it’s possible but more often than not it requires a C type charger which is the latest port available. Also your laptop must have the female port to support the C type USB cord and should have the feature of USB- C charging.Thirdly you will require a type- C to type- C USB cord. These cords, as the name suggest have type- C output on both the sides of the USB. 90003 90002 So, to begin with connect one port of the USB to the laptop and the other to your phone. A menu will open as it does when you connect your phone for charging. Click on it and select ‘supply power to other connected device’ and there you have your laptop on charge. 90003 90002 However laptops require more power and drawing so much power from the phone might soon drain it out of battery.Also this technique of charging is not recommended as both laptop and phones have different battery types, lives and charging capabilities. This method of charging will definitely destroy the battery of one device or the other or the USB. It may lead to permanent damage or damage the battery to an extent that it will drain out faster. Good USB cords specially type- C are expensive and can face permanent damage due to this experiment. 90003 90002 Your phone can be your hope of last resort if you are faced in a situation where you need just a little power to complete a task with your laptop.90003 90002 It is pertinent to make provisions for the aforementioned methods of charging laptop without the use of the traditional laptop chargers. 90003 90002 Indeed, it can safe you of stress and make your day. 90003 90002 Did you ever try to charge laptop without charger?

It works a little differently. Please, note that you do not actually charge your laptop with this charger. What you actually do is take out the battery and connect it to the charger.This will only work if removing the battery from your laptop is possible. If your battery is fixed in place and can not be removed, you can not use this method to charge a computer without a charger. The biggest advantage of this method is rapid charging. When it’s done, you just put the battery back into your laptop and continue working. 90003 90042 Super Batteries 90043 90002 If you have a «super battery» — a separate source of power for your laptop, you can also charge it separately. Just like in the previous case, you will be charging a laptop battery without a laptop (take the battery out of the laptop).Also, you will need to be sure that the «super battery» will fit your device. Once the battery is charged, insert it into your computer and start working. It will last for about four hours. These batteries are rechargeable, and they do not work that long after recharging. 90137 90003 90002 Needless to say, before you use any alternative way to charge your laptop without an original charger, you need to do a little research to make sure it’s suitable for your specific device. Some laptops can react very differently than expected or you, as a user, can mix something up and break your device.For example, do not try to charge your computer via USB adapters. You can use those for USB devices only. It might damage the laptop architecture and even cause a fire. 90003 Bestseller No. 1 Super-Capacity Li-ion Battery For Toshiba Satellite P200 series replace PA3536U-1BRS, PA3537U-1BAS, PA3537U-1BRS, …… 90002 Battery type: Li-ion; Capacity: 84Wh; Cells: 9-cell; Voltage: 10.8V; Capacity: 7800mah. 90003 SaleBestseller No. 2 XCMRD Battery 14.8V for Dell Inspiron 15 3000 3521 3537 3542 3543,15R-5537 15R-5521,3541 3531,17 3721 3737 5737 5721…… Bestseller No. 3 NinjaBatt Pro Laptop Battery for HP 807956-001 807957-001 HS04 HS03 807612-421 807611-221 240 G4 HSTNN-LB6U HSTNN-DB7I …… 90042 Conclusion 90043 90002 The use of non-original battery charging methods definitely requires a bit of knowledge and research: you must be one-hundred-percent sure that you have chosen the correct items.

They may not be as prevalent as power banks for mobile phones and tablets — perhaps because most people simply find an outlet at a cafe to charge their notebooks. However, they’re out there; you just have to know where to look. 90003 90002 It does take a bit of research, though. Many portable laptop chargers are finicky and do not always work.Some are even too big and too heavy to be worth carrying, so you’re better off just going to a cafe and paying for a cup of coffee or charge at an airport or a train station when you’re traveling. 90003 90002 However, if you do find one that works for you, it’s definitely worth it for the convenience. The best portable laptop chargers are some of the most useful gadgets for digital nomads and remote workers. That’s where we come in; we found the most reliable and best value portable laptop chargers on the market.This way, you do not have to sift through the bad; you just have to pick the best for you. 90003 90002 90003 (Image credit: MaxOak) 90010 1.

Great for laptops that draw up to 60W of power, this portable charger is also designed to jumpstart a car.It even has its own jump start port and comes with its own set of jumper cables. And, unlike other portable laptop chargers, which only come in one or two colors, this one comes in seven different colors / design patterns, making it ideal for folks who do not care for the minimalist approach. Unfortunately, it does not have a USB-C port, which the AC outlet should take care of most of your laptop charging needs. 90003 90002 90003 (Image credit: ZMI) 90010 4.

Maybe you’re going to a friend’s destination wedding or a family trip to the beach, or perhaps it’s camping with your friends. You decide to bring your laptop with you because it’ll be nice to stream movies, get some work done, or play a PC game in your downtime. A laptop can help you feel at home when you’re away from home. 90003 90002 Oops! When you’re unpacking in your hotel room, you realize that you’ve forgotten to pack your laptop charger (or worse yet, you accidentally leave it in the airport power outlet).Your laptop only has a 10% charge left, so it looks like you’re going to have to do without it on this trip. That essential email to the boss will have to wait. 90003 90002 But wait! It does not have to be that way. Believe it or not, you can actually charge your laptop without a standard laptop charger. It’s really quite easy to do, and you should learn how to do it if you’re a fellow 21st-century dweller who feels compelled to take your laptop with you anytime you hit the road. 90003 90002 Here are not 1, not 2, but 3 different ways to charge your laptop when your laptop charger is MIA.90003 90010 How to charge a laptop without a charger 90011 90002 Every laptop is built with an internal battery. To get the battery charged, you’ve just got to supply it with some electricity. Most of the time, we plug our laptop into a power outlet in our home, and the electricity travels through the cable and into the battery. 90003 90002 A laptop charger is arguably the most effective way to transfer power to your laptop battery, but there are other ways to do it, too. All you need is: 90003 90016 90017 A power source 90018 90017 A way to transfer the power to the battery 90018 90021 90002 Let’s get into it.90003 90010 Can you charge a laptop with USB? 90011 90002 One of the most common questions I get is 90027 «can I charge my laptop with a USB connector?» 90028 This actually depends on the type of USB port you have on your laptop. 90003 90030 USB Type A is a non-starter 90031 90002 If you are you currently using a wired mouse or wired keyboard and you unplug one of them from you’ll see that there’s a rectangular connector at the end of the cord; the metal piece that you insert into the computer.This is called a Type A connector. 90003 90002 It’s the most common USB connector, and whenever someone says «USB» you can reasonably assume they’re referring to USB Type A. Most likely, your cell phone charger has a USB Type A connection, too. Unfortunately, while you can use Type A to power smart devices, you can not use it to power your laptop. 90003 90002 Type A can exchange a sizeable amount of data, but it’s not capable of transferring the huge amount of power that’s needed to replenish your laptop battery.Type A just can not deliver enough wattage. 90003 90030 USB Type C is a power-full ally 90031 90002 However, USB 3.1 introduced a new kind of connector called USB Type C, or «USB-C.» Unlike Type A, USB-C has more of an oval shape. It’s designed for high-wattage connectivity, which means it can transfer far more power than Type A can, and at faster speeds. 90027 Much 90028 faster: 90003 90016 90017 Type A (USB 3.1): Speeds up to 10 Gbit / s 90018 90017 USB-C (USB 3.2): Speeds up to 20 Gbit / s 90018 90021 90002 It’s about to get even better 90003 90002 USB4 will be released in 2019, and the accompanying USB-C connector can transfer data at speeds up to 40 Gbit / s.90003 90002 Long story short, you can not charge your laptop with USB Type A, but you can charge your laptop with USB-C. 90003 90010 1. How to charge a laptop with USB-C 90011 90002 If your laptop has a built-in USB-C port, then you’ll be able to charge your laptop via a USB-C cable — you just have to make sure the cable has a plug adapter (the box-shaped plug at the end of your phone charger than can plug into an outlet). Some laptops, in fact, use a USB-C cable as the primary charger. 90003 90002 To charge your laptop via USB-C: 90003 90062 90017 Plug one end of the USB-C cord into an outlet 90018 90017 Plug the other end of the USB-C cord into your laptop 90018 90067 90002 That’s it! Easy as pie, so long as you have access to a USB-C cord.But that’s the glaring problem — what if you do not have access to one? Unfortunately, ordering a USB-C cable would not be any easier than ordering a new laptop charger. And making a stop at a computer supply store may not be possible, especially if you are stuck on a Caribbean island for that destination wedding weekend. 90003 90030 Plan ahead for options 90031 But if you’re in the market for a new laptop, you might seriously consider getting one that has at least one USB-C port. The USB-C connector is rapidly gaining popularity.It’s safe to assume that in the future, most laptops will come with USB-C ports, and we might even see the elimination of USB Type A altogether. The point is, more people in the future are likely to have USB-C cables, so there will be a better chance that someone can lend you one if you lose yours on a trip. Currently, you’d have to find someone who happens to have the exact same kind of laptop charger has you do, which may prove more difficult. 90002 Nearly all of our popular HP laptop brands have at least one USB-C port: 90003 90002 90075 Note: 90076 Always check product specifications before you buy.90003 90010 2. How to charge your laptop in a car 90011 90002 A car has electricity, right? And whether you are on a road trip in your own vehicle, or renting a car when your airplane lands, you can take advantage of the power it produces. It’s fairly straightforward to use it to charge your laptop. You’re going to need two things, though: 90003 90016 90017 AC Adapter (USB Type A connector on one end USB-C connector on the other end). This USB Type A to USB-C adapter is perfect for use in a vehicle 90018 90017 USB car charger 90018 90021 90002 It’s easy as one, two, three.To charge your laptop in a car: 90003 90016 90017 Turn on your engine 90018 90017 Plug the car charger into your vehicle’s charging port (you might not even need a car charger since many newer vehicles have USB ports you can plug into) 90018 90017 Plug the USB-C connector into your laptop 90018 90021 90002 90075 Note: 90076 Never leave your laptop unsupervised in a vehicle and in clear view. That could make it more vulnerable to theft or damage from overheating. 90003 90010 3. How to charge your laptop with a power bank 90011 90002 One of the easiest ways to charge your laptop is with a power bank.A power bank is basically a portable battery for your laptop. All you’ve got to do is connect the power bank to your laptop. The best thing about power banks is that they do not need to be plugged into an outlet while they’re charging your laptop. 90003 Power banks come in a variety of different models, and they’re not all built with the same charging capacities. You’ll be able to charge less-powerful laptops with a USB Type A power bank. If you want to charge a more powerful laptop, like a mobile workstation, then you’ll need to get a power bank that’s USB-C-based.USB-C power banks can also power other USB devices, like your smartphone or tablet. 90002 Most likely, your power bank will have enough charge to replenish your laptop battery only one or two times, especially if you’re recharging a more high-powered laptop. It’s important to remember to plug it into an outlet and replenish its charge. When your power bank runs out of charge, you will not be able to use it to recharge your laptop. 90003 90002 That’s why it’s best to reserve your power bank only for when you really need it — like when you accidentally lose your laptop charger.Always keep your power bank inside your laptop bag. 90003 90010 Get a laptop bag or case 90011 Whenever you hit the road, whether you’re traveling long distance, backpacking through Europe, or just going on a weekend getaway, you should always bring a laptop bag or backpack. A laptop bag is not only for storing your laptop. You should also keep accessories in it that you can use to recharge your laptop in the event you lose your power cord. In fact, you should keep accessories that can recharge all of your electronic devices.90002 The first thing that a laptop bag will do is protect your laptop. Many HP laptop bags are built from weather-resistant fabric and zippers that can withstand rain or hail. The interior of the bags are usually padded with soft, shock-absorbing materials that will protect your laptop if you accidentally drop it, or if your road trip gets rough and your laptop bag starts bouncing around in the back seat. 90003 90002 Arguably the most rugged HP laptop bag is the HP Spectre 13.3 split leather sleeve, which is tough enough to go on an Indiana Jones-caliber adventure.90003 90002 The best bags also have special protective features against RFID readers. If you carry credit or debit cards with you, know that there are devices that can scan your card information from a short distance. That’s right. A cyber thief with access to such a device could stand behind you in line at the coffee shop and scan your personal and financial information right off your card without you knowing. 90003 90002 They might not actually do it at a coffee shop, because that would be difficult to do without drawing attention to oneself.But it happens often on the street or on public transit. Many HP laptop bags have exterior zippered pockets that are resistant to RFID scanning, so whether you’re going across the world or across town you can safely store your credit and debit cards in the pouch without worry that you’re get hacked by a cyber thief. 90003 It’s also not a bad idea to get a full-blown backpack for your laptop. A backpack is a bit more ergonomic than a laptop case, and it will enable you to squeeze a bunch more electronics devices inside.90010 What to pack in your laptop travel backpack 90011 When you’re on-the-go, make a habit out of bringing a laptop backpack that has all the supplies you need for a successful tech-filled journey while you’re away from the home office. Here’s what you should put in it. 90002 90075 1. 90076 First and foremost, keep your laptop in there. If you want to be extra safe, put your laptop in a laptop sleeve first and then put the laptop case in the backpack. You never know when the road’s going to get rough, so you should take any measure you can to protect your laptop.Remember, you’ve probably got a lot of sensitive or valuable work information or personal information stored on your laptop, like work projects or family photographs. Do not risk losing those. 90003 90075 2. 90076 Second, you should insert a fully charged power bank. Try not to use your power bank unless you really have to. It should be mostly for emergency use in case your laptop power cord is down for the count. 90075 3. 90076 Third, bring a travel adapter. If you’re traveling internationally, you might wind up in a country that does not have outlets that are compatible with your laptop.A travel adapter has interchangeable plugs that enable you to plug into a foreign outlet. 90002 When you’re traveling abroad, having fully functional electronics may be key in keeping you safe and ensuring that you do not miss any transportation arrangements. Be sure to pack one of these when you’re headed out of the country. 90003 90075 4. 90076 Lastly, pack a USB port hub. A USB port hub is an incredibly useful device to have when you’re traveling with your laptop. Its main function is to give your laptop a larger number of available USB ports.Typically, a USB hub comes with 4 to 7 additional USB ports so you’re able to easily connect all your USB devices when you’re removed from the organized workspace in your home office. 90002 There are powered port hubs and unpowered port hubs. Powered port hubs are great because they supply power to your connected devices (so your devices do not have to draw power from your laptop). If you only have a limited time to charge your USB devices, you could use a powered hub to charge all of them simultaneously, and you do not even need an extraneous number of outlets.Some HP powered hubs come with SD card slots and USB-C ports.
