Looking for a travel charger that can handle AA/AAA NiMH as well as 16340 and 18650 (21700 and 26650 would be great). Single cell would be fine, something like a Nitecore F1 but that does NiMH as well. Does such a beast exist?
The Olight UC is the most compact charger but lacks the powerbank feature. The Armytek Handy C1 Pro is similar to the F1 and also does NiMH.
