## Customer Reviews

### ⭐⭐⭐⭐⭐ This one works, don't buy cheaper you'll regret it !
*by A***K on 10 May 2025*

This one works, I have it fitted between my 300W solar panels charging two 12 v leisure batteries and the drive battery. This is in my camper conversion , once fully charges this trips and the charge from the solar goes through to my drive battery. I tried to save money and bought a cheaper version with out a volt display. I didn't know it failed for months when I got in to trouble with a flat. Never a slow start again with this fitted and easy to see it operable status at a glance

### ⭐⭐⭐⭐⭐ Works fine
*by S***S on 5 May 2025*

Workers fine

### ⭐⭐⭐⭐ Keeps your leisure battery separate whilst still able to charge
*by M***T on 19 November 2024*

This is perfect for keeping your leisure battery charged from the alternator whilst not draining your car battery when the engine isn't running. Everything you need is in the box apart from tools. The instructions are easy to follow and should be fairly quick to fit. The display tells you all the info you need and LEDs show the current mode.
