A compact four bay charger that handles both lithium and Ni-MH AA and AAA cells and screens out bad ones. It powers from USB-C, so you supply the wall adapter, and it does not take larger cell sizes.

Overview
Four independent charging channels let the XTAR charger fill each cell on its own, whether a lithium AA or a Ni-MH AAA. An LCD reads voltage, the charger refuses alkaline and damaged cells, and a repair mode tries to revive over-discharged Ni-MH batteries.
Support for both lithium and Ni-MH chemistries in one small charger simplifies a mixed battery drawer. It runs from USB-C power, and no wall adapter is in the box.
Who it's for
Families and hobbyists running remotes, toys and flashlights on rechargeables get one charger for both types. People with larger cell sizes will need another charger.
Pros and cons
- Charges lithium and Ni-MH
- Four independent slots
- Rejects alkaline and defective cells
- Repair Mode for old Ni-MH
- No wall adapter included
- AA and AAA only
- Charge time stated for lithium only
Performance notes
Each slot charges on its own channel, so a nearly full cell does not hold back an empty one. Charge speed depends on the USB power source, and a weak phone adapter slows it.
