Whether you’re topping up a battery between weekend drives, recovering from a flat in your driveway, or preparing for roadside emergencies, the right battery charger makes all the difference. In 2025, there are plenty of great options on the market – but not all chargers are built for the same purpose.
In this guide, we review the top-rated battery chargers available in Australia today, highlight what to look for when choosing one, and explain why some are better suited for the garage while others, like Boost N’ Inflate, are made to go with you anywhere.
Wondering which type suits your situation best? Read our Battery Charger vs Jump Starter Guide.
What to Look for in a Car Battery Charger
Voltage Compatibility
Most Australian passenger vehicles use 12V batteries. Make sure any charger you buy matches that. Some chargers also support 6V or 24V systems, but unless you're charging trucks or motorcycles, 12V is your focus.
Amp Rating
-
2A trickle chargers: Best for slow maintenance or long-term charging
-
6A–10A smart chargers: Great for regular use or top-ups
-

Smart Features
-
Auto shutoff when full
-
Reverse polarity protection (prevents damage if clamps are swapped)
-

Portability
Some chargers are built for bench use in a garage. Others are compact, portable, and designed to live in your glovebox or boot – ready when things go wrong.
Charging Modes
Look for chargers that offer:
-
Standard charging
-
Maintenance/topping up
-
Engine start mode (if you ever need a jump)
-
Recondition/deep cycle recovery (for deeply discharged batteries)

Final Word: Charge Smart, Stay Ready
Every car owner should have access to some form of battery backup. For some, that’s a full-featured smart charger that lives in the garage. For others, it’s a glovebox-ready jump starter that kicks into action when they need it most.
The Boost N’ Inflate covers more than just battery charging – it handles flat tyres, flat batteries, and flat phones. It won’t replace a trickle charger, but in real-life emergencies? It might be the most useful tool you own.
