A Nitecore Charger will cover a lot a bases for different conventional cell types, has a 12V input. It will charge NiMh and NiCd and rechargeable Lithium Ion for those higher power 18650 flashlights etc. But you will need a consistent 12V 12+ Watt power source. i.e a 20W Solar Panel + Charge Controller + SLA battery system i.e as shown in Les's Photo.

No USB input though as you will only really find these on smaller capacity chargers due to the USB power specification limitations.

The Nitecore charger is very handy to charge 4x18650 cells for a Fandyfire UV-S5 Flashlight for home use, when you need some serious illumination.

A compact Soshine SC-S7 will also charge the similar range of cells, but only one cell at a time. Useful for portable Solar PVs of 5+ Watt specification for light weight back packing
