A laptop is a very convenient device: lightweight, mobile, powerful. However, the battery charge literally evaporates before our eyes with intensive use. What laptop owners just don’t do to extend the battery life of the device. The easiest and most logical way is to use portable batteries (Power Bank). But you need to know how to charge a laptop from Power Bank. In addition, not every portable battery is suitable for this process. How and what to do? The answer to the question will be in this material.
Which power bank to choose?
The answer to the question of whether it is possible to charge a laptop from Power Bank depends on the characteristics of the latter. Not every portable battery is suitable for these purposes. The rated current for charging the laptop should be 2 amperes with a voltage of 19 volts. Most portable batteries have much lower performance, as they are designed to charge smartphones and tablets. Now about the capacity of the device. The minimum battery capacity of the laptop is 6000 mAh. While standard portable batteries have a capacity of 3000 to 5000 mAh. Naturally, such a device is not enough to fully charge the laptop battery. You will have to purchase something with a capacity of 10,000 mAh or higher. And only then it will be possible to decide how to charge a laptop from Power Bank.
Now about the connectors. To charge the laptop requires a wire with a specific type of connector. Moreover, they may differ from different manufacturers. You won’t guess here. But some power banks (specifically designed for charging laptops) come with a complete set of connectors. There will definitely be no problems with these devices. And the average portable battery will not work. Neither current nor voltage is enough. Not to mention that connecting such a device to a laptop is very problematic. However, we turn to the answer to the question of how to charge a laptop through Power Bank.
Stage 1. Charging the most portable battery
So, let's move on to the description of the charging process. First you need to remember that before you think about how to charge your laptop from Power Bank correctly, you first need to charge the portable battery itself. If it has just been purchased, then it is worth leaving it to charge for the night. So he will gain full capacity. Even if the charge indicator shows full capacity earlier, do not disconnect the power bank from the network. This information may well be false. However, all of the above is true only for portable batteries with a decent capacity of 20,000 mAh. If the capacity is less, then the battery may be charged earlier. In this case, you should read the operating instructions for the device.
Stage 2. Charging the laptop
So, how do you charge a laptop from a “power bank”? If the portable battery is specifically designed to charge such devices, then there is nothing complicated about it. The algorithm is ridiculously simple. First you need to wait until the laptop is fully discharged. Then you should connect the powerbank to the laptop charging socket using a special adapter or a separate cable. Next, turn on the portable battery. Charging will start automatically. It is worth noting that using a laptop at this time is not recommended, since all the power of the portable battery will be spent on maintaining the operation of the device, and not on charging its battery. It is worth waiting for the completion of the charging process and only then start using the laptop for its intended purpose.
How effective is such a charge?
So, as we found out, you can charge a laptop from Power Bank. But no less relevant is the question of how effective such charging is. And does it harm the laptop battery? Let's just say that the voltage used in advanced portable batteries (19 volts) is exactly the same as when recharging a laptop battery using standard charging. This means that there will be no harm to the laptop battery in this regard. The only thing that can fail is the charging speed. Not all portable batteries provide enough amperage. It is possible that with a current of 2 amperes, the laptop will charge much more slowly than when using a standard charging adapter. However, you need to sacrifice something. It is impossible to get everything right away. Nevertheless, the effect of charging with a power bank is pretty good. You can charge your laptop anytime, anywhere.
And if the voltage of the Power Bank is less?
What to do if the voltage of the portable battery is less than required? How to charge a laptop from such a Power Bank? 12 volts is very small. But you can do something with such tension. However, you will have to purchase a special converter. It will help to convert insufficient 12 volts to acceptable 19 volts. However, this converter is quite an expensive pleasure. It will be much easier and cheaper to get a good portable battery. Yes, and charging directly through a power bank is much preferable to using different types of “crutches”. You never know what can happen. So it will be more reliable. And power surges will not bother.
Positive feedback on portable laptop batteries
What do owners of portable laptop charging devices say ? Many note that such gadgets more than once helped them out in a variety of situations. For example, power banks are very popular among those who like to travel. Users claim that there is nothing easier than charging a laptop from Power Bank. And indeed it is. It is very convenient to use such portable batteries in trains and airplanes. After all, far from everywhere there are 220 volt sockets. Powerbank can operate in various conditions. And some of these devices are also protected by a shockproof and waterproof housing. This is a great advantage. However, the price of such devices is quite high. But this is not so important. The main thing is that you can charge your laptop anywhere and anytime.
Negative reviews on portable laptop batteries
Oddly enough, but there are those who found flaws in such useful devices. The first thing that users did not like was the size of portable batteries. Indeed, the dimensions of particularly capacious devices are quite large. In the jeans pocket, these are definitely not fit. Also, many were not happy with the price tag of the batteries in question, designed to charge laptops. But it normal. After all, not everyone is capable of this. Another drawback (according to many users) is the lack of current. Because of this, the laptop is charging prohibitively long. And you can’t use it during the charging process, otherwise the battery will not charge. But this is a normal state of affairs. In a portable battery, it is simply physically impossible to make a decent amperage. You have to sacrifice charging speed. But you can charge everywhere. And this is the main advantage.
Conclusion
So, above we examined the question of how to charge a laptop from Power Bank. It is very easy to do. But only if the portable battery is designed to charge such devices. Conventional power banks are not suitable for such a task. They purely physically will not be able to fully charge the laptop battery, as they do not have sufficient capacity, have a very low amperage and cannot provide an acceptable voltage. So you need to use only devices specifically designed for this business. No other way.
