l Firstly, the most important is the battery type assembled in a power bank.
As mentioned above, there are several kinds of batteries types from lithium polymer, to 18650. Of course, the most reliable is lithium polymer which has great reputation in market and won`t have any worry about explosion. Wimar technology ltd all power banks are assembled with lithium polymer batteries purchased from a list company.
l Secondly, it is the battery transform ratio determining the power bank.
How to test transform ration? Just using it to charge your phone and remember the electricity power and charging time. For example, if the power bank capacity is around 8000mAH, it should charge iPad from Zero to full while iPad capacity is more than 6000mAH. The 2000mAH is consumed by inside components. Then the ratio is 6000mAH divides 8000mAH equal 75%. That`s not the best but it is already a better power bank than others. Then other important point is the charging time. It depends on the Output current. iPad requires 2A input at least and with 2A output power bank charges mobile phones in a faster way than 1A output.
l Thirdly, the last but not the least to mention about is the shell material and surface treatment.
Usually most power bank shell adopts PPS material which is already hard enough for using. Fortunately, Wimar power bank adopts a better treatment on surface, called IML (In mould lable), which makes surface smoother and brighter. And moreover, the surface hardness reaches to 2H hardness, anti-scratching.
Of course, there are other methods to figure out good power bank from others. Anyway, Above 3 methods are just for power bank distributors` reference. If you have any interesting to bring up more, please leave a message here.
