  • Fadt and easy
I had a charger for my 18650 batteries and it just stopped working. I tried this one and it works perfectly. It is easy to load and unload and the charge indicator is easy to check It charges the batteries quicker than the previous charger. Would definitely recommend!

  • As Described
this item is what is to be expected. I will say the cord is a bit on the short side, not by much just could use another couple of inches. Otherwise the charger works great!!!

  • GREAT,BUT UGet what you pay for
It does what it says as far as it's marketing but you really have to manipulate the 10-440s or Triple A's to get them to actually make contact so it's a little difficult and it's pretty slow but it was inexpensive and it gets a job done

  • Bought two replaced one and one stopped working now only one left.
Bought two of these because I had 8 batteries to charge at once. They worked fine the first time I charged the batteries but the second time one of them did light up or charge. I returned after I had it for a week and they were very quick to replace it. Now trying to charge the batteries again one of them didn't work, again. Returning it for refund. ... show more
