Nitecore brings us the F2 charger. This little guy is impressive, powerful, and extremely durable all jammed into a very compact unit. The battery slots are literally the size of only two fingers, making this charger super lightweight and portable. Though the size is small, this beast is equipped with the capability to charge your batteries at 2A and can also store power from multiple devices including solar panel. When charging batteries on this charger the batteries charge independently, as well as if you have an external device plugged in, the unit will distribute current to both at the same time. Constructed from polycarbonate, it's also practically indestructible. If you need a charger but you're always on the go, this is the one for you.
