MC2 V2 2-slot USB-C Charger - XTAR

The XTAR MC2 V2 is all about simplicity: two independent slots, USB-C power, and easy-to-read indicators. It is especially suited for users of a dual-battery box mod who want a compact charger to keep in a pouch or on a desk.

Each slot can deliver up to 1 A with a suitable 5 V/2 A power supply. The charger recognizes the installed cell, manages charging automatically, and can revive certain batteries that have dropped to a very low voltage, with no manual settings needed.

Which batteries to use?

Check the size, voltage, and chemistry of each cell before placing it in the charger. Diameter compatibility does not always guarantee that protected batteries, which are longer, will fit in the slot. Never force a cell and always respect the polarity indicated on each slot.

For a dual-battery box mod, keep a pair of the same brand, same capacity, and with the same number of cycles. Charge both cells together and replace the whole pair if one shows abnormal wear.

Tips for safe charging

Inspect the battery's insulating wrap before each charge. Do not use a cell with torn wrapping, or one that is deformed or has been dropped. Place the charger on a stable, dry, and clear surface, away from heat sources. Use a cable and adapter that match the stated input, and remove the batteries when the cycle is complete.

Maximum current is only relevant if the battery and power supply can handle it. A gentler charge may be better for smaller capacities. Do not leave charging unattended for long periods and always transport batteries outside the device in an insulated case.
