FC2 2-SLOT USB-C CHARGER - XTAR

FC2 2-Slot USB-C Charger - XTAR

The XTAR FC2 combines a compact build with manual current adjustment. This lets you choose a gentle 0.5 A charge, a daily 1 A recharge, or a maximum 2 A current on a single bay when the battery and power source allow it.

Its two slots work independently and accommodate common vape Li-ion batteries as well as several Ni-MH or Ni-Cd formats. The USB-C input simplifies setup, while the indicators show the real status of each cell.

Which batteries should you use?

Check the format, 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 into the bay. Never try to force a cell and always respect the polarity indicated on each slot.

For a dual-battery mod, keep a pair of the same brand, same capacity, and with the same number of cycles. Recharge 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 or damaged 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, then remove the batteries once the cycle is complete.

Maximum current is only relevant if the battery and power source accept it. A gentler charge may be better for smaller capacities. Do not leave a charge unattended for long periods and always transport batteries outside of devices in an insulated case.
