Compact but powerful
Great little charger this, takes both AA and AAA batteries plus other sizes that I do not possess. The state of charge and power is displayed for each of the batteries on charge, and it will take them in pairs or even individually. Charges quickly and you can even put the batteries in either way round and it sorts out the polarity.Excellent unit.

useful many features charger
This charger works well and charges 18650 batteries quickly. The other features - time on charge and milliamp/hours supplied only show for 30 seconds then display reverts to voltage.

Kratax do these things well.
Having to acquire a new LI-Ion battery system for 2 new items, I returned to Kratax, for a universal charger, which included 18650 3.7v cells.I've previously used Kratax Li-Ion AA cells, with a dedicated charger, and they've been brilliant.

Packed in after 3.5 years
Was good for about 3.5 years, then it started malfunctioning and is now useless. Worked well with my 21700 batteries.

Not impressed.
The 4th slot stopped charging after a few weeks, sometimes it will register full when it hasn't charged the battery properly.

Ticks all boxes but have marked a 4 star only. See comments why below
Could not give full 5 star because I don't yet know how long batteries retain charge. Jury's out there.
