الاجهزه الالكترونيات الامريكية قد تحتاج الى محمول فولت من ١١٠ الى ٢٢٠.قد تحتاج إلى محول كهرباء
مميزات خاصة
UPS Function: When the power supply has power directly from the power supply through the boost circuit to the load power supply, and at the same time to the lithium battery charging. Once the power supply is disconnected, it will automatically start the battery path to supply power to the load through the boost circuit
Boost Circuit: Peak power up to 20W, rated power up to 15W, BOST boost circuit, built-in 12A high-current MOS, small cage up to 96%
Li-ion Battery Protection: Over-shock, over-discharge, over-temperature, over-current protection (if the misuse of short-circuit into the protection state does not output, access to 5V charging automatically activated to restore the output)
Module Function: The module can achieve seamless switching of external power supply and battery dual-channel power supply (no delay), suitable for small power DC equipment, instruments and other uninterruptible power supply solutions, power outage self-starting, self-charging on incoming calls
Multi-interfaces: The module is equipped with a universal micro USB charging interface and a direct DC5V input to charge the Li-ion battery

Caveats:
1. Board has MOS and other components, has been soldering iron inductance electricity or classic damage, please ensure that the use of the soldering iron has a ground (and plug ground conductive), it is best to wear anti-static gloves to operate!
2. Installation of batteries pay attention not to install the reverse
3. Please select the power supply enough power to keep the board working properly!
4. Board power supply should not be higher than 5V
5.It is normal for the module to heat up when working with high power, please pay attention to heat dissipation.
