Product basic parameters:
Input port: Micro USB (Android port)Input requirements: 5V constant voltage power supply can be used for charging input power, the most matching charger is 5V 1A or moreOutput port: USBOutput parameters: 5V 1A / 5V 2A
Requirements for rechargeable batteries:
Available battery(3.7V-4.2V polymer lithium battery):
18650 battery, mobile phone battery, flat battery, MP3 battery, can choose single cell power supply, or multiple cell parallel power supply(does not support the series). (Note: increasing capacity in parallel and increasing voltage in series, can only be used in parallel!)
Can be connected in parallel with 2-6 pcs 18650 batteries!!!
Batteries are not available:
Dry cells, batteries, 1.2V rechargeable batteries, nickel hydrogen batteries, 3.2V iron lithium polymers, lithium batteries, etc.
Product installation should pay attention to the following points:
1. The battery should be connected in parallel, only the voltage between 3.2-4.2V can work, 18650 flat head and polymer batteries are available;2. The battery is connected to the motherboard, B+ stands for the positive pole, B- stands for the negative pole, if it's connected reversely will burn the motherboard;3. The old batteries and new batteries, the batteries which model and brands are inconsistent, these battery can not be mixed.
