Six-slot Li-ion charger for multiple battery sizes

This six-slot smart charger accepts a wide range of 3.6 V and 3.7 V lithium-ion cells including 10440, 14500, 16340, 17670, 18490, 18500, 22650, 25500 and 26650 formats. It suits hobbyists, flashlight users and anyone who keeps several rechargeable cells in rotation. Each bay operates independently so different sizes can charge at the same time.

AC and DC input with low heat and silent operation

The unit runs from AC 120-240 V 50/60 Hz at 15 W maximum or from a DC 12-24 V source also rated at 15 W. With only 500 mA per slot the charger stays cool and produces no fan noise during normal charging cycles. The black casing blends into a workshop or bench without drawing attention.

Steady 4.2 V termination across all bays under load

Each channel delivers a constant 500 mA until the cell reaches 4.2 V ± 1 %, then stops cleanly without overshoot. All six slots maintain this behaviour simultaneously during extended sessions. Users needing faster recharge rates or support for chemistries other than 3.6 V/3.7 V Li-ion will need a different charger.

Questions about this item

How do I set up the 6-slot charger on AC mains, and which step do people skip?

Plug the unit into a 120-240V 50/60Hz socket; the step often missed is confirming the 15W max input rating matches the outlet before connecting any 16340 or 26650 cells.

What will need replacing after heavy use, and when?

The spring-loaded contacts that grip 18490 and 14500 batteries lose tension over time; expect to swap the charger once slots no longer hold cells firmly at 4.2V ± 1%.

What limit appears first during a long 6-bay charge session?

Total output is capped at 500 mA per slot, so all six bays combined draw the 15W input ceiling — thermal throttling kicks in before any single 17670 reaches full voltage.
