This is very ideal situation, sometimes moving the power to protect the batteries, the batteries in the output voltage is too low when the couple will protect mobile power molipow, cut off the output, we can not always put the entire mobile power batteries run out of power . Another case is the mobile phone power supply output voltage is lower than the charging voltage requirement (the iPhone is 4.35V), will trigger the protection mechanism couple phone mobile power, such as the iPhone will prompt "Charging is not supported with this accessory" This case for the use of mobile power capacity will be reduced. 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 Couples mobile power customized gifts, the 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 product with almost no difference between A couple of mobile power supply manufacturers, capacity and number of cycles will be a sharp decline in two months. C product polymer batteries like 18650 disassemble products, usually discarded batteries, 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. Couples mobile power charging treasure | Couples mobile power | Shuo Shuo provide by Shenzhen New Energy Co., Ltd. Shenzhen Shuo New Energy Co., Ltd.
