Technical Suggestions for a portable air pump

Anderson has several Auto Zones, O'Rileys & Advanced Auto, only one Advanced Auto was open today so I bought the cheapest type that will plug in a cigar litter, it was on sale for 18 bucks, I need something right now, I've already used it, green slime. it does the job although it's a bit slow, much better than nothing.

I do intend to buy a Derwalt due to the fact I already have several 20 volt batteries & tools. HRP

 

I have two Viair’s. One has a max pressure of 100psi that I use for cars and another with max pressure of 150psi that I use for our motorhome. The smaller one plugs into the power port (for us old timers that’s the cigarette lighter) the larger has jumper cable type clips. I use the larger one to adjust or add air in the motorhome tires to about 100psi before before driving every time. Never had any problems with either in over 10 years. Amazon has a good selection and are usually the cheapest. I also have a jump box with an air compressor but is very slow to pump up anything.
