Adjustable amp rate for restoring batteries or fast charging.
Works great, gives in depth data and can be controlled at what amp you want, totally dead and not used for a long time need a low 0.5 amp and long time to restore, recently used batteries can be fast charged at 2 amps. Doing the right amps can repair older batteries using this functionality.

Slow but sure, good price.
The charger can charge a number of rare batteries. My battery was 21700. I could buy the charger cheaper than the battery and it worked just fine. It does charge slowly, but for $13 fast enough. :-)

Fits 21700 lithium ion batteries no problem
Bought to charge lithium ion 21700 batteries for power tool battery pack repairs. Takes several hours (3+ hours for new batteries) to charge batteries even at the 2 amp setting. Also you have to supply the USB type a power supply (charge block).Also where this is a ni-cd and lith ion charger. It auto detects battery voltage to decide which type of battery is in charger. If battery has less than 1.5 volts it will see this as a ni-cd battery and stop charging at 1.6 volts. Had to jump lithium ion batterys with good battery to get voltage up above 2 to get to charge lithium ion to the full 4.2 volts. Lithium ion batteries should never be drained below 2 volts as it could damage the battery so I assume this is a safety feature to keep them from overheating.Has worked well but I do wish I had purchased the larger 4 slot charger.Also accepts 18650 batteries no problem.

Good value
Device works as intended and is quite good at charging devices quickly. I was genuinely surprised by the quality and value you get for your money. I would recommend this as a battery charger but if possible try to wait for a sale cuz this often goes on sale.

Tiny but works for 21700 batteries.
Feels quite rinky dink, but it charges the batteries no problem without heating up. I had to Google my batteries for the amp setting for my battery, as the directions are TERRIBLE as usual for this type of electronic gadget. Small gripe is that you can't see the percentage of the charging for both slots at once, but no biggie really. For the price it's a great value!

Works well but...
Charges batteries with no problems. It can't charge gum stick batteries without modifications.
