How to choose a suitable phone power bank?

By  Steve Lowry 2018-10-30 6243 0

People are more and more fond of going out to travel. At this time, mobile power will be an indispensable thing. Let me see how to choose a good mobile power supply.

Capacity of power bank

The power bank capacity, which ranges from 2000mAh to more than 10,000mAh , and it's important to note that they are all 3.7v, so if you're charging something which isn't 3.7v you need to convert Whether it's enough or not. Capacity is discounted during charging, for example the iPhone's battery is 1420mAh, but if you want to fill it once, perhaps 2000mAh's power bank is enough.

Power bank weight

A more than 10000mAh power bank is about 500g, you may already have more than 1 kg notebooks in the bag, paper and pen, Kindle, some cosmetics and toiletries, etc., more than 500g may be the last straw breaks the camel, which cause your shoulders can't bear the weight, and you need a backpack which can support the weight of 3kg, than transfer the weight to the hips. So, consider your needs, just enough. Don't go for too much capacity and ignore the weight.

Electric core


The electric core, which used to be 18650. It is said that it is not good. As for how it is not good, opinions vary. But if you start using a lithium-ion battery cell right now, which is going to be a little bit better than the 18650 one. As we all know, the batteries have a life span. It's going to be 300 cycles, if your power bank which is equipped with second - hand electric core may soon be out of date, and that capacity will be compromised.


Input and output ports

If you have two or more devices, it is best to choose a power bank with two output ports. And, if you have an iPad or Android tablet, you'd better choose one with two output ports, because one of them will be a 2A export. Generally one of them is 1A, the other one is 1.5A or 2A, depending on the capacity. If you plug in the power bank and watch a video or play a game, the charging speed cannot even catch up with your power consumption that would be terrible.


Input and output ports


Generally, the mobile power supply can only accept the charging input of 1A, and the input speed is discounted. The input of 1A cannot be fully charged with 1000mAh in an hour. In addition, some power banks are equipped with a 220V plug, so you can save the charger and charging line and plug directly into the socket.


Pass through function

Pass through function, which means it can be used to charge power bank while charging other devices from the output port.

Wrap up


So, seriously analyze your needs. If you only charge your phone and you can charge it at work and at home every day and at night, then you only need to have enough capacity to charge your phone once or twice. This kind of power bank is about 100 grams of weight, which is lighter.


If you are traveling and have an iPad, you can consider power bank above 10000mAh. Use your phone and iPad every day, and plug in a power bank pack to recharge. At night, the iPad charger is plugged into the socket, the Micro USB cable is connected to the power bank, and the two ports of the power bank are respectively connected to the phone and iPad to charge them. The next morning when you woke up, all the devices were fully charged.
