I just bought a Schumcher XP2260 that has the air compressor, 2 - 12 volt outlets, internal inverter with 2 - 120 volt outlets. I paid $99 for this, it was available at both Walmart and Lowes for the same price.
I used the air compressor 2 times to air up a tire on a Suburban, the compressor only ran for ~5 minutes before it kicked out after getting hot and the tire was not full yet. If you read the literature it says it can take 6-24 minutes to air up a passenger vehicle size tire.
I bought this to have out on some property I'm clearing, I have used it to jump start vehicles and used the air compressor.
We will also take it with us in our toad when we go on trips to run small cooling fans for the dogs and emergencies.
