## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great
*by D***. on August 27, 2025*

Easy install, seems to do the job well. Made for a much easier trip when facing long travel days that otherwise would be draining the camper house battery bank.

### ⭐⭐⭐⭐⭐ A must have for charging lithium deep cycle battery.
*by P***. on October 13, 2025*

Keeps lithium deep cycle battery from overheating vehicle alternator.

### ⭐⭐ Narrow and small terminals now easy to connect
*by A***R on May 21, 2025*

Prods - built strong, works good also Cons - terminals for power cables too small - impossible to use standard cable terminals. Need to grind every terminal from both sides to fit then in narrow spaces. Moreover power connections should be rotated on 90 degrees because it’s difficult to connect to power terminals. Would return products and newer buy VEVOR dc to dc because it’s has terrible power terminals. I love VEVOR products, but this charger must be modified. Attached photos of example good terminals other dc charger.
