FAQ
-
Will the inverter drain my battery if I leave it attached?
Like all inverters, it draws a small amount of standby power. Remove it when you're finished to protect your battery's lifespan.
-
Is it safe for my laptop?
Yes. It works well with laptop adapters, phone chargers, and lighting.
-
Does it have low-voltage protection?
Yes. It shuts off automatically before your battery is fully drained, so the cells stay healthy and can recharge later.
-
Can it run a power tool or heater?
No. It's rated for 140W continuous output, so it isn't suited to high-wattage devices like heaters, saws, or kettles.
