Share a few of my principles for choosing a power bank
< br >
1. Choose mainstream brands
< br >
Under the premise of sufficient budget, preferred millet, purple rice, green link, Anker, Huawei, Samsung, etc., these brands are better with materials
< br >
The pursuit of cost-effective selection of well-known parts factory Beijing, speed, Taiwan power, Rome Shi, Bysi, feather Bo, etc., these brands safety, quality is qualified, capacity will not be false.
< br >
Do not choose unknown small factories, quality safety is not guaranteed, and the capacity is also a lot of virtual targets.
< br >
2, choose the right capacity
< br >
Do not look at what complex on-board conversion rate, rated capacity, just remember that 10,000 MA can probably charge the mobile phone 6000,20000 charge 12000, and then choose according to your own needs
< br >
3. The lighter and more portable, the better
< br >
The same capacity of the charging bank, the smaller, the thinner the thickness, the lighter the weight, the better.
< br >
4, it is best to have fast charge
< br >
The capacity of mobile phones and charging banks is getting larger and larger, and the charging speed is too slow without fast charging.
< br >
And whether you need to buy additional data cables, chargers.
