I looked a bit closer at some of the power inverters on Amazon, and while they all love to advertise high amperage ratings, it usually only applies to the USB output. The A/C output is usually around 2.5 amps. This means that if the Auger PID gets current hungry, a power inverter won't cut it. I'm seeing why Cannabis Hardware sells a 12v PID for use in cars. The bummer is that their 12v PID isn't compatible with their usual coils, so at that point you're not just buying a new PID, you're also buying a new head assembly. It's possible a UPS could act as a safety net, but I'd have to see what the power draw looks like on the Auber before going with that route, and at that point the jank factor is pretty high. That all being said, it's very possible the Auber doesn't draw nearly as much power as I'm thinking when using the regular 100w coil, so maybe a basic power inverter would be fine. If anybody knows how to test current draw from the Auber I'd love to see what the spikes look like and how long they last.AUBER 300b SPECS:

Seems the specs are close, but bear in mind, running any of these inexpensive converters near their “stated” capacities, they can get hot, and fail early.
