Something to watch for with electric impact guns, the cheapies on sale are often 3-4amp and the better ones are 7-9amp. Wait for the better one to be on sale, the 3amp would not loosen lug nuts on my F150, the 7amp spun them off.
The number one thing I hear (as a consultant for a tool company that sells compressors) , it wont power my 'X', The CFM ratings are usually optimistic, there is peak CFM, the moment you pull the trigger, and sustained CFM. In Chinese imports its usually "generous". Don't expect a small compressor to keep up with a die grinder, orbital sander or spray gun. Nail gun, blowing dust, pumping tires, air brush , no problems.
Even getting a tubeless tire to pop the bead back can be a challenge.
Bigger tank just means more initial air, you still need the right size pump to put air into that tank.
The air filters on compressors are crap, the import compressors are complete crap. If you blowing dust out of things or sanding / die grinding keep the compressor away from where you are, the pump (a vaccuum) just sucks all that dust into itself and grinds the valves and piston seals and the dust comes back down the hose and wrecks the seals in your tools.
sorry if this all sounds common sense, 20 people a week used to write into the company complaining tool X wont do Y. Nobody likes to hear you bought the wrong tool.
Know why there is a shutoff switch for low oil in a generator , because idiots would buy a generator, ignore the HUGE label that says must add oil before starting engine. Call later and say WTF , it ran for 20 mins and seized. Now the sticker says engine WILL NOT start until you add oil.
