Do not be surprised, this is reality! As the mobile phone charging circuit there are some losses, assuming the phone charging circuit efficiency is 80%, then the above mentioned 2960mAh battery last only 2368mAh, can give two iPhone mobile phone charging, or to a battery charge In about 2400 phone is full, for example, the Sony Xperia Z L36h 2330mAh or 2300mAh for HTC One. If you can not achieve such results, then the mobile power capacity is vacuity correct. 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 Shenzhen mobile power, usually a battery factory for customers custom made mobile power, high requirements in terms of quality, 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, usually discarded batteries, poor quality mobile power magic bubble, 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. Mobile power _ Master can fast charge (certified) _ mobile power provided by the Shenzhen Municipal Shuo New Energy Co., Ltd.
