Giantz 12v 30a Portable Car Battery Charger for Fast and Safe Charging for 12v Batteries in Cars, Boats, Caravans and More

The Giantz 12v 30a Portable Car Battery Charger is a smart, no-nonsense way to keep 12v batteries charged and ready, whether it’s in the shed, the garage, or out on the road.

Built for everyday Australians who value reliable gear, this compact unit delivers steady charging with full safety protection built in.

Using Pulse Width Modulation (PWM) technology, the charger ensures efficient power delivery without energy waste.

The system self-regulates to prevent overcharging, with an automatic floating charge mode that protects battery health long term. 

It’s compatible with both gel-cell and wet-cell lead-acid batteries, making it a handy tool for everything from motorbikes and utes to caravans and boats.

The charger includes built-in protection against short circuits, over-voltage, over-current and overheating, so you can connect it and walk away with peace of mind.

It’s SAA and CE approved, and fitted with high-quality battery clips, an 85cm cable, and a durable outer shell designed for tough conditions.

Weighing just 1.7kg, it’s light enough to stash in the car or carry to a job site, yet powerful enough to bring a flat battery back to life quickly.

Whether it's for everyday use or as a backup in the glovebox, the Giantz 30A Charger is a practical addition to any 12V setup.
