Sounds like a fantasy mostly..
Those plug-in DC air compressors you see on Amasin sites, cost $10-50 or so do work, but pay attention to the "duty-cycle" a 20% duty cycle means run it 2 mins and it needs to cool off 8 mins (10 min cycles). 50% means 5 mins on, 5 mins off. Running it past its rated duty cycle will heat it up too much and burn it out sooner or later.
There are DC air compressors that have a 100% duty cycle, so you can run them non-stop. You would want this for a big volume like a mattress or boat toy.
These are more expensive, but worth it if you are big into inflating things, and it will be great for inflating the car tire as those will take 30 mins or so if using these little compressors. You can set it and walk away...
IF you have a way to inflate a car tire then use this trick... It will cause lower digestive tract pains for many members here though, so it is just an option, not for everyone:
Make an air hose with Schrader fittings at one end (car valve type), and on/off valve on the hose and the little lever lock is needed.. The other end should be a fitting that fits your item to be inflated, so you might need more than one hose, or a way to adapt the toy end of the hose.
Here is the fun part. Use the air pressure in your spare tire as an air tank. It will inflate a mattress and you will barely notice any pressure change in the tire. You can pre-fill the spare tire to its max psi for longest results. It will fill fast.
When and if you need that spare tire, then you will have the inconvenience of waiting for the little air compressor to fill the tire back up. The tire will not be completely flat, maybe even have enough psi to drive on, so it will not take 30 mins to top it off. You can also keep it topped off every few times you use a lot of air out of it, and never run it down to zero. I have friends that do this method.
This method is not for the faint of heart, as you will see below soon
