1. Watch the parameters of the machine: This method is relatively applied to those unknown small processing mobile power. For example, a volume of mobile power supplies is high, such as 6000-7000mAh power, it is very careful.
The electrical cell of the mobile power is the most 18650 battery and polymer lithium electricity. 18650 battery is cylindrical, 18mm in diameter, 650mm high. The capacity is up to 3000mAh, which is generally made into a cylindrical moving power supply of a distinct rounded corner, such as the PN-902.
3000mAh 18650 lithium electric products is between 25-30, mobile power finished products can be considering the battery. Polymer lithium battery can be customized, without a fixed shape. The capacity of the polymer can be large, while increasingly having volume, generally producing a box-type mobile power source.
Generally, the polymer of a credit card size is between 2500-3000mAh. 2, look at the outer shell of the machine: Basically, the appearance of a product represents the quality level of the product. Even if it is implicated in a beautiful shell, the overall industrial design is also a gap between the real product.
Since we are buying, there is only a kind of product in front of us, there is no contrast, here we have to look at: The interface between the power supply and the outer casing is very good; during shaking the mobile power, it is It is not a abnum that is loosened; seeing the outer casing seam, it is not a glitch 3, the upper and lower lids or part of the part of the part of each part is not a neutral gap, which is not a average outer casing. These can be light. Or look carefully in the sun, if you have these aspects, the most distinct time.
In addition to these, pay attention to the surface color is not a color difference, is there a black spot. .
