Common Questions Before You Buy

Will it work with Australian appliances (240V)?
The inverter outputs 220V ±10%, which means up to 242V at the upper range. Most Australian appliances rated for 240V tolerate this range, but check your appliance's specs to confirm.
Can it run a microwave or kettle?
Yes for small to medium appliances rated under 4000W. Check the appliance wattage label. High demand items like kettles (typically 2000W+) work but will drain the battery fast.
Is it pure sine wave?
This is a modified sine wave inverter, suitable for most appliances. For sensitive electronics like CPAP machines, medical devices, or studio audio, look for our pure sine wave models.
How long will it run before draining my battery?
Depends on battery capacity and load. A 100Ah battery running a 500W load will last roughly 90 to 120 minutes before recharging. Start the engine periodically to top up the battery.
What protection does it have?
Built in protection for overload, short circuit, low voltage, overheating, and reverse polarity. The inverter auto shuts off if any condition is exceeded.
