In for one. We had an inverter in the back of our car. the power cord eventually got dry rotted from the heat in the trunk when not being used. So the price is right for this replacement.

Menards has a similar one for only $11.22 right now ($10 after their 11% rebate).

https://www.menards.com/main/300w...487669.htm

Worth it if you've got a Menards nearby for in-store pickup, but shipping kind of kills the deal.

Make sure your vehicle has the circuitry for this. Many cars' 12V sockets are only rated (and equipped with a limiting fuse) for 10 or 15 Amps, whereas this would require at around 30 Amps minimum (allowing for conversion inefficiency) to output 300W sustained.

Does this have some sort of remote mobile app via BT to monitor usage and potential also turn on or off via app?

The USB ports on this are mostly for charging phones etc while you also need the plugs, so you don't have to alternate what's using the cigarette lighter port. The main thing I've used one for is charging a laptop while on the road. These are also useful in power outages as a temporary generator (this one is not powerful enough to run a fridge though).
