I bought 2. From the first minute of use, the plates would come out every time you removed the batteries, in both chargers. One of them broke, with very light use and without ever using Fast Charge. Bought from different stores, one did not have a car lighter cable in the box, while the other had it in the packaging, but the other one did not have a power cable (!!), and I had to buy one. I cannot know if the good battery that broke is due to the faulty charger, but I mention it because I cannot exclude it. What I can exclude is buying this product again.

I bought two chargers, one of them was making a crackling sound inside and I got scared so I recycled it, and the second one stopped charging the batteries after 1 year.
