I have a 300w power inverter which plugs into a typical 12v socket.

The socket isn’t stock, I wired it myself and it has its own 10a fuse. I used a fuse tap, tapping into the accessory circuit.

I have a 200w device I’d like to run off of the 300w inverter, but the fuse blows immediately.

Is there any danger in using a 20a or 30a fuse?

    Power (watts) = Voltage (volts) * Current (Amps)

    300W at 12V pulls 25 fucking amps, you better triple the wire gauge before upping the fuse and starting a fire.

    Aside from that, the inverter puts out a squared sine wave which is good for exactly no electronics, only AC motors
