## Customer Reviews

### ⭐⭐⭐⭐⭐ Awesome Purchase
*by V***N on June 3, 2024*

I love this charger. I can get 4 batteries in it and still use my vape and have lots of back up batteries. I also use it to charge the batteries in our flashlights. It works great.

### ⭐ Very Disappointed!!
*by B***L on April 9, 2022*

The media could not be loaded. First time I ordered I got a used burnt, melted plastic smelling charger with a torn bag underneath and no wire ties that I wouldn't dare even try to plug in because it looked dangerous needless to say I sent it right back and thought it might be a mistake I'm willing to give another chance to get it but since I didn't have a replacement option I opted for a refund. I placed the order again the second time and this time around I got a brand new sealed unit and this one is completely dead. The minute you plug it in with or without the batteries it just flashes and doesn't charge at all. Very disappointed and would recommend looking elsewhere for a charger.

### ⭐⭐⭐⭐⭐ Battery charger
*by T***Z on August 24, 2023*

Excellent battery charger and easy to use just put the batteries in if the light is white the batteries are charging and when the batteries are done charging it turns blue can't get no easier than that
