### ⭐⭐⭐⭐ Good product for the price
*by K***I on December 11, 2025*

This is a great charger. I bought this specifically for C batteries so it was a good deal for what it’s for. My only concern is the batteries seem loose when you put them in to charge and you have to have a block or something to plug this into with a usb. Most my other batteries chargers I have plug into the wall so it’s less space but this does not so that’s a little more of an inconvenience in my opinion. Charges great though!
