XTAR MC2 2-Bay USB Li-ion Charger | 18650, 14500, 26650

Key Features

Two bays, each detecting its own inserted cell and setting the appropriate charging current independently of the other, so a smaller 14500 that finishes its charge cycle early doesn't sit there waiting on a larger 18650 still topping off in the neighbouring slot, and there's no need to charge similar-sized cells together to keep timing aligned.

It runs off Micro-USB rather than the newer USB-C standard, worth calling out both ways: on one hand it means the MC2 is compatible with an older phone charger, cable or power bank a household likely already has, no need to buy a new USB-C cable specifically for this device. On the other hand, Micro-USB caps the practical charging speed lower than a USB-C model would reach, so charging times run a little longer here in exchange for that broader cable compatibility.

Covers

• 14500, 16340 and 18650 cylindrical lithium cells
• Compact flashlights and everyday gear, not the larger 21700/26650-format tactical lights
• Three-stage charging: constant current, constant voltage, trickle top-off

Overheat, reverse-polarity and short-circuit protection are all built into the circuit as standard safety measures rather than left for the user to manage through careful handling alone. The ABS plastic housing is built to survive being tossed into a bag or a glovebox rather than needing careful handling.
