The Golisi Needle 2 USB Charger is a compact charger with 2 slots. It has a USB power port for 1A charging. And it's compatible with almost all types of cylinder-shaped rechargeable batteries. You can charge two batteries at the same time.
Battery compatibility: Li-ion 18650, 21700, 26650/Ni-Mh/Ni-Cd/AAA/AA (almost all types of cylinder shape rechargeable batteries)
The ability to not charge at 2A x1 or 1A x2 is a bit dumb.
