Product Features
  

         
4.5-5.5V power supply, suitable for single lithium battery (parallel connection is not limited), maximum 1.2A, can stabilize 1A current as required.
         
Suitable for all types of 3.7 V lithium batteries, including 18650 and aggregate batteries
         
With overshoot and overdischarge protection, overdischarge protection 2.9 V, charge cut-off voltage 4.2 V
         
When there is no external input voltage, it automatically switches to output mode, supports small current output of 5V, and supports output of about 450 ma. If the output is 1A, the voltage will be around 4.9V-4.5V depending on the power.
         
Automatically switch input and output, charge the battery when the external voltage is input, otherwise discharge, the charging green light flashes, the green light is always on when fully charged, the light is not on when discharging without load standby, and the blue light is on when discharging with load. The standby power consumption is approximately 0.8 ma.
