There are a variety of models of different brands and the range of prices is really outrageous. Also, in order to sell more, many stores are lying about the power and autonomy of the batteries and lead to negative comments from the users. Some seller not say that they lie to sell and deceive their customers and they say that the sellers are not well informed of the operation, for that reason then we have listed the typical questions and answers to make you have more information about power bank.
The vast majority of batteries like all other electronic products, are manufactured in China.
You can charge your power bank or external battery just like you do with your mobile phone charger. It has a mini usb input that you can connect with your mobile phone cable and light. You can also charge it with another external battery.
That depends on the REAL Capacity of your external battery. If your battery has 1500 mAh it will logically take less than if you have an external battery of 12,000 mAh. A part of that will also depend on whether the charges to the home network (220V), from the USB port of your laptop or if you do it with another battery. Batteries usually have an indicator to warn you when it is charged.
The charging time of your power bank or external battery depends on several factors, temperature, level of charge, support, time the battery has, etc ... for that reason it does not always take the same time to load.
MAh means the milliamperes of consumption per hour. The capacity of the batteries is measured in mAh. The more mAh, the more autonomy the battery will have.
This is one of the typical lies or mistakes that sellers make and it causes the logical anger of the client that is made with a power bank and then they realize that it is not true. In order to really calculate how many times you can charge your mobile you should do the following operation:
REAL CAPACITY x CONVERSION RATIO x MOBILE BATTERY HEALTH / MOBILE CAPACITY
That is to say: 12000 X 0.8 X 0.8 / 1500 = 5.12 (YOU CAN CHARGE 5 TIMES YOUR MOBILE BATTERY)
The health of the battery is the state of your battery. The capacity of your battery goes down more and more over time. For that reason the battery of your mobile does not last so long after having used it for 6 months. Depending on the quality of the battery some tend to lose autonomy much faster than others.
The PCB means the plate where the control chips go. The more quality the more times you can charge the battery and the less autonomy you will lose over time.
The size of the 18650 is fixed. The size of lithium polymer batteries is flexible.
The power of the 18650 is greater. Polymer batteries are much safer.
The price of 18650 is lower. Lithium polymer batteries are more expensive.
The autonomy of the 18650 is lower. Polymer batteries discharge more slowly.
The useful life of 18650 is less. Polymer batteries have a longer life.
The 18650 batteries usually have 1300 mAh at 2200 mAh
The external battery using 1 bat 18650 are from 1200 mAh up to 2600 mAh The external battery using 2 bat 18650 are from 2500 mAh to 4400 mAh The external battery that uses 3 bat 18650 are from 3750 mah to 6600 mAh. So, the one that uses 8 batteries of 18650 the result will be between 10400 and 14400 mAh.
Yes, but they are very expensive.
Completely false. It is many brands are buying external batteries to factories in China that sell generic and simply put their brand. After that, the brands sell them more expensive.
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.
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.
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.
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.
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, which means it can be used to charge power bank while charging other devices from the output port.

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.
