Quality of internal lithium battery

    Although power banks look similar, the inner is clearly different. Part of the decision just mentioned, in addition to cost control chip, naturally, the quality of the lithium battery itself. Such as Tesla Motors recently very red, is to use the 7000 Panasonic NCR 18650 3100mAh lithium battery. Generally speaking, lithium batteries from Japan such as Panasonic, Sanyo has a good performance and reputation, we can focus on what manufacturers in the purchase from what the internal lithium battery label brands. Of course, price is a key, expensive is not necessarily the best, but the use of low-cost mobile power lithium battery poor must not be very good.

    Output current, interface and control chip

    Another parameter can not be ignored is the output current, usually "A" (ampere) to represent. Mobile power supply output current will determine the charging time, and the application of the device. Generally speaking, the maximum current charge acceptance when the phone is 1A, 2A and tablet PCs will need more. So, try to choose when buying mobile power dual USB interfaces, different output current products, such as 1A + 2.1A configuration, you can meet the charging needs of iPhone and iPad.

    Since the mobile power is actually used to control the discharge of an integrated circuit, the control chip is also very important to recognize the charging status of the device, and a corresponding change in the charger behavior. Generally speaking, having a fast charge, excellent security level of mobile power and other advanced features are used to better control chip. Therefore, the purchase may be appropriate to look at these features and price, after all, a sub-price goods, dozens of dollars but has a large capacity mobile power, in addition to poor battery performance, control chip usually extremely cheap, can not provide good performance and security.
