Details

A flat battery is one of those problems that always seems to happen at the worst time — before a long drive, first thing in the morning, or halfway through a trip. The Giantz 20A Battery Charger is a straightforward way to recover dead or low 12V batteries and keep them maintained, whether you're at home in the garage or heading out to work on a vehicle in the field.

The integrated PWM (Pulse Width Modulation) charging system helps prevent power loss during the charging process, delivering a consistent charge to the battery. Once the battery reaches full charge, an automatic floating charge mode takes over — meaning you can leave it connected without worrying about overcharging or battery damage.

Built-in protection against over-voltage, over-temperature and short circuits adds another layer of confidence when charging. It's SAA approved, compatible with both gel-cell and wet-cell lead acid batteries, and includes 90cm battery clips to connect directly to your vehicle, boat, ATV, caravan or any 12V setup.

At 1.2kg and a compact footprint, it's genuinely portable — easy to keep in the back of your 4WD, in your workshop or stowed in a caravan bay for when you need it. Check battery compatibility with your specific setup before use.
