CM120 FAQ


Q: Which batteries can the CM210 charge?

A: CM210 can charge a 2S lithium battery, and a 2S high-voltage lithium battery can also be charged, but the maximum voltage can only reach 4.2V.

Q: Which devices can be used as the power supply of CM210?

A: CM210, with universal Type-C 5V DC input, can automatically adjust the charging current according to the power supply to ensure that the power supply is not overloaded and achieve charging-friendly. Adapters, computers, mobile power supplies, car chargers, and other power supply equipment can be used as the power supply of CM210. Charging is as convenient and simple as a mobile phone. Safely charge anywhere, anytime.


Q: After the charger is powered on, the red light flashes just after inserting the battery or within 1 minute, why?

A:There are 2 possible reasons.

1.The current detection resistor is burned out, and the MCU detects that the current is too large.

2.The switch tube is damaged, so it is unable to switch normally. There is no current output or the output current of the power supply is too small.
