## Customer Reviews

### ⭐⭐⭐⭐⭐ Lead acid battery charger
*by N***L on 10 January 2026*

Used to charge my remote controlled model lead acid battery, basic charger but does what it's intended and very functional

### ⭐⭐⭐⭐⭐ A mighty little package
*by A***H on 27 November 2025*

Highly reliable and still working perfectly after regular use and even charged a flat car battery overnight without overheating. Good build quality.

### ⭐⭐⭐⭐ Good value.
*by A***R on 12 September 2025*

Good value for the price, trickle charges my classic car nicely, and cuts out when the battery is fully charged. Be aware it is a 0.6amp charging rate, so takes a while if the battery is low. Cables are a good length and the clips fit securely on the posts. I would have liked a read out of charge level, but for the price you can't have everything!
