Tire Compressor broken again

Hello Minor problem compared to others but I wonder how long these compressors/Seal kit last. I had to replace one with the 2013 volt and now the one with my 2015 Volt broke. At the switch. I was expecting this one with the 2015 to go as it was laboring alot after 35PSIG where the units with the 2013 hummed right along to 42 PSIG. Actually the unit reads about 45PSIG to get 42 PSIG on the tires. You have to overshoot what pressure you want to see on the display. I think I checked this a few years ago with a hand gage and the display is more accurate then the compressor gage.

12v inflation devices blow lots of fuses and have very short lifespans. Compressors make hot air, hot hoses, hot nozzles, hot meters. Hence the higher pressure displayed. NEVER run them for more than 1 tire until they have completely cooled to room temperature.

Use CO2 cartridges. Trust me. Way better. Way faster. Dry air instead of wet.
Use CO2 cartridges only in emergency situations. Never use the C02 cartridge to regularly inflate your tires, once tires are inflated with a C02 unit air, air will dissipate through your tire. you will notice a noticeable loss of air overnight having used the C02 cartridge. If you do use a co2 cartridge, I would then deflate the tire and refill tire as your normally would do once you get to a safe spot.
I think the cycle life is charges for the main battery unit. I certainly wouldn't rely on that unit for regular usage to top off the tires, but great for a backup emergency situation. And with the additional capability of being able to jump start the car, $60 is cheap peace of mind.
only good to use if the car tire is low but no canister to plug the tire, not that those canisters ever worked for me.
C02 is soluble in rubber and not constrain by normal permeation loss, it can transfer through the bulk of the rubber resulting in severe pressure loss. We use C02 cartridges because constrained in a moderate pressure cartridge other gases would require a much more dense cartridge to constrain the gases. Anyway and all stories have an anyway C02 is a quick option for quickly pumping up the tire but loss of pressure is real and takes place in a very short period of time.
