Key Features:
- Smart Charging & Repair Mode: No need to worry about overdoing it—this charger automatically tweaks the charge to avoid overcharging or leaving your battery a bit limp. The pulse repair function can give tired batteries a new lease of life, although it can’t work miracles on those that are properly knackered.

- Versatile Charging Modes: Whether it’s a car, motorbike, AGM or GEL battery, or you fancy giving the repair mode a go, you can easily switch between options to suit whatever you’re working with.
- Temperature Compensation: British weather can be all over the shop, but this charger isn’t fazed. It automatically adjusts voltage and current to suit the temperature, ensuring your battery gets the best treatment come rain or shine.
- Top-Notch Safety Features: It’s loaded with protections—so there’s no need to panic about reverse polarity, sparks, overcharging, short circuits, or things getting too hot under the bonnet. There’s even a mini fan to keep things cool when the going gets tough.
- Built to Last, Easy to Use: Made from tough ABS plastic, it shrugs off knocks and scrapes. With a UK plug, it’s a doddle to use—just plug in and you’re away.
