【Frequently Asked Questions (FAQ)
Q1: What is the 0V activation function?
A1: If a Li-ion battery has been deeply discharged (drained to 0V), most standard chargers will refuse to charge it, thinking it's broken. The XTAR MC1 features smart 0V activation, which can safely apply a small current to revive the battery and bring it back to a usable state.
Q2: Does the charger stop charging automatically when full?
A2: Yes. The MC1 uses a professional 3-stage charging algorithm (Trickle -> Constant Current -> Constant Voltage). Once the battery voltage reaches the 4.2V cut-off and the current drops below 130mA, the charger automatically stops to prevent overcharging and protect the battery.
Q3: Will this charger work with my 21700 battery?
A3: Yes. The XTAR MC1 has wide compatibility and supports many battery sizes, including 20700 and 21700 batteries, as well as both 18650 and 26650.
Q4: How do I know when the battery is charging?
A4: The MC1 has a simple, easy-to-read LED indicator. Green light means Standby or Fully Charged. Red light means Charging in progress. If the light turns Gray, it indicates an abnormal situation or that the battery is inserted in reverse.
Q5: Can I use this charger with my standard USB wall plug?
A5: Absolutely. The charger uses a standard USB Type-C input. You can use your smartphone's Type-C cable and plug it into any 5V/1A (or higher) USB power adapter, power bank, or laptop USB port.
