TC2 USB-C Charger for Compatible 3.7V Li-Ion Cells
Recharge a compatible cylindrical cell between uses without a large charging station. The TC2 USB-C charger is specified for selected 3.7V lithium-ion battery formats. It is for users matching a charger to the actual cell chemistry and size.
- ✅ Prepare a spare cell — The charging cradle gives a compatible battery its own charging position.
- ✅ Use a USB-C power connection — A suitable external supply powers the charger.
- ✅ Pack a smaller charging accessory — The compact format fits a travel kit.
- ✅ Reuse supported cell formats — Named sizes cover several cylindrical battery types.
Check chemistry as well as cell dimensions
Named formats include 16340, 14500, 18650, 21700 and 26650. Check the actual charger's accepted cell length and chemistry; a similar-looking disposable battery is not automatically rechargeable.
The charger is described for 3.7V lithium-ion cells. Do not use it for alkaline, Ni-MH or LiFePO4 batteries unless the supplied instructions explicitly permit them. Battery, cable and adapter inclusion are not confirmed.
