@3DNub_364413 I'm just using the MOSFET as a relay to disconnect the USB power supply from the battery, since the led in it would probably drain the battery over time. Could have just done it with the switch but that tiny switch isn't rated for the current. #unelegant workaround
It might still be a good idea, but I don't know that you need the mosfet. These car chargers tend to accept 12 to 24v on their own.
