The output voltage range of mobile power charging treasure molipow, although some devices with USB interface, but also requires you to use the mobile power supply. However, you should pay attention to the input voltage range of your device, the voltage output range universal mobile power is 5.0 ± 0.5v. If your device is within the required range of input voltage range is not in the power of the movement, then I suggest you do not use your device as a mobile power supply fast-charging treasure to ensure the life of your mobile power. Polymer batteries polymer batteries are divided into three qualities, namely product A, B goods, C product A product polymer batteries is the best quality new polymer battery, battery manufacturers are usually custom-made on quality requirements are relatively high, all parameters can compliance, without any unusual products. Under normal circumstances the big manufacturers of mobile power will use A product batteries. B product polymer batteries such batteries in the production process, for some reason, some products can cause flaws in appearance, capacity, voltage, or other parameters have a little problem, so the product is called B goods. Also, if A product batteries stock for too long, such as 3-6 months without shipping the product, usually also called B goods. B products 1-2 months of use of the previous A product with almost no difference, the capacity and number of cycles will be a sharp drop after 2 months. C product polymer batteries like 18650 disassemble products wholesale charge treasure, usually discarded batteries charge treasure, of poor quality, usually in appearance, capacity, voltage and other indicators are substandard. Such products there are security risks, has the power to move its production capacity not only on the problems, is likely to cause damage to the digital devices. Consumers also need to be wary of buying. Charging treasure manufacturers, large energy (certified), charging treasure provided by Shenzhen Shuo New Energy Limited. Shenzhen Shuo New Energy Co., Ltd.
