What is the advantage of an OBD2 scanner on a booster?

Saves unnecessary garage visits. It reads engine fault codes and often allows you to clear the 'Check Engine' light directly from the trail.

Does the built-in compressor inflate tires quickly?

It's not an expensive ARB compressor. It's noisier and takes longer, but for weekend off-roading, it gets the job done and saves money and space.

We compared the relevant jump starters in our community — UTRAI and BUTURE. One for daily drivers, one for off-road, one with a compressor.
