very nice , slim and charges slow and steady for a good charge. great charger for the price.

Easy to use charging my 21700 batteries without issue has setting for 3 charging amp rates Good deal

Inaccurate charge readings but it works fine and it eventually gets to 100%

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. :-)

Charges my vape mod batteries perfect! Small , compact and light weight makes it a perfect charger for travel.. Hope it lasts!

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.

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!

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.
