How long does this take to inflate a medium SUV (like a Grand Cherokee) from 20 to 40 after going on the beach?

Simply a guess...I have a 4 door Lexus with 16" tires. To inflate 5psi takes just under one minute, so 20psi on same size tire would probably be @ 4 minutes....but some variables have to be accounted for, e.g. temperature, weight, whether the tire is sealed on the rim, connection of compressor is tight, etc. Like all compressors I have used, the gauge on the hose in not entirely accurate, so I always use a handheld gauge just to verify.

Unless you have unusually humongous tires on the vehicle my "guesstimate", assuming a cold tire pressure, would be five to seven minutes per tire. Not really sure about the relevance of the beach. As Ron Coleman points out, there are too many unknown variables to provide a definitive answer to your question.

It'll take days to inflate it by mouth. If you use a dinky car charger air pump, it takes about 30 minutes. If you use an inexpensive electric air pump it takes about 5 minutes. Deflating is pretty quick, but good luck fitting it back into the carrying bag it comes with. It's very difficult to be able to get every little bit of air out and roll it up as flat as it was when we got it.

You would need to buy a pump that is designed for air mattresses, it will have a head on it that fits right into the air hole, and yeah doing this by mouth would probably take more than 45 minutes!

We used this pump to air up beach balls, it took about 3-5 minutes on the size of the beach balls. I believe it would take much longer to air up a queen size bed, I would recommend a bigger pump instead of this one. The Coleman is good for smaller items. Hope this helps.

It inflates very quickly. About a minute or less. The fan is small but powerful.

I use a rechargeable air pump with a switch to deflate . It only takes 2 minutes.

I would guess mine took about 1 minute to inflate. My son did it every night and it was really quick!

While this item is great at starting a car with a dead battery, it isn't worth much at inflating a beach ball, let alone a tire. Look else where if that is a need (I'd recommend a VIAIR compressor. They work great and are as strong as air compressors you find at convenience stores.)

Hi I bought mine just before a camping trip --It inflates with the separate air blower that takes 4 D size battery's --I had one that had the pump built in and it would go soft halfway through the nite --Enjoy ---Rog

It's a smallish hand pump that works fine to inflate the kayak in less than five minutes. You could buy a larger, sturdier pump that might cut the time down to three minutes.

I used a portable car tire inflator. Yes, it was a bear, but only took about 10 minutes. Fortunately it seemed to hold the air well over the summer. Good luck.

I have a basic hand pump that I use which it only takes me 3 minutes to inflate.....super easy!

You have to inflate this mattress by blowing air into it. The instructions say it takes about 20 strong breaths to inflate the mattress.

Well it takes longer than 3 seconds. The biggest issue we had was dumping out the sand from the side pouches before folding. And the wind can definitely be difficult. It usually only took us a couple minutes though. It's not bad, wind and sand considered.

"Takes a few hours to inflate" is an exaggeration. It maybe takes an hour to inflate if left to itself, but if you want to speed up the process just blow yourself, a few blows and it's inflated in minutes. I wouldn't let it stop you from buying these Therm a rests. They are good quality at a great price.

It takes about 1 minute to fully inflate with the pump that comes with the bed. Just used it for the first time two days ago - it is great!
