Review on Universal Smart Battery Charger: 4 Slots for Rechargeable Batteries - AA AAA C Ni-MH Ni-Cd Li-ion IMR 18650 26650 25500 16340 14500 18500 10440 18350 RCR123A - LCD Display, UL Listed by Bob Collins

Including connector. It loads a bit slow, but for me that's normal - there may be issues depending on usage. It is very easy to use with expandable slots. The maximum charging speed is 500 mh for 1-2 batteries and charges up to 4 at the same time. The display shows the battery level, which is very convenient. Can only be used with rechargeable batteries (Li Ion, Ni MH, Ni Cd, LiFePO4) - I've used it to charge 1 battery at a time and up to 4. I bought the lithium ion batteries separately - I love it , that you can use it for small and larger batteries because the slots expand. You can toggle the loading speed above by pressing the A, B, C and D buttons. The default is the highest setting. This is not a small item (just something to be aware of) - car adapters need to be ordered separately. CONS - Depends on your battery (e.g. C or 26650) if the battery is wide. This charger cannot hold 4 at the same time.
