XTAR MC1 Plus The XTAR MC1 Plus Charger is XTAR's latest portable USB mini charger with a 1A maximum constant current. Compared to our original MC1 charger, you can charge an 18650 as well as other lithium-ion batteries at twice the amperage. The MC1 Plus features the ability to automatically detect the battery being charged and choose the most suitable charge current at either 0.5A or 1A. The MC1 Plus makes a great upgrade to the MC1 charger but is not a replacement. Features: Automatically selects most suitable charging current for batteries (0.5A or 1A)Reverse-polarity and shortcircuit protection circuitThree-stage charging and 0V battery activationMicro USB port to supply power for the chargerAdopts IC temperature monitor to avoid over heatCompact size and portabilityLow heat design The max charging current of XTAR MC1 Plus is 1A current. To fully charge a VTC5 just takes 3 hours. It can also automatically choose the most suitable charging current (0.5A, 1.0A) for your batteries to ensure the longest lifespan for your batteries.
