I've been looking for an inverter like this for a long time but never caught one at a price I was willing to pay. Reviews are comparable to other options. I just ordered one.

Keep in mind if you actually try to pull 300 W through this, you're probably going to blow a fuse on your car first.

300w at 12V is 25 Amps.

The pictures of recommended uses show a CPAP machine. I would not recommend a non-sine wave inverter for a CPAP machine. In my experience most things with a motor don't work correctly on a non-sine wave inverter.

Fine for charging things and I sometimes run a TV off a cheap inverter when the electric is out. But IMO, best to spend the extra on a pure sine wave inverter and not have to think about it.

I just ordered one using the app. When you paste the code in, make sure to press the right arrow and you should see a response saying the code was applied.

I am new to this stuff. Do I need this inverter to use with a Portable Power Station, 300w (296w)?
