Q Industries Air Pump, Multipurpose 12 Volt Portable Inflator/deflator, by MasterFlow for Inflating Full Size Car Tires and Inflating/Deflating Air Mattresses and Inflatable’s

I bought this with all the intentions of pumping up my raft. For the price and reading the specs, I really thought it was going to do the job. FAIL... It barely produces air right out of the box. It claims to be able to pump a car tire in 2 minutes. Wrong, it barely pumped in in my tire which was on;y needing about 10 more psi and that took 4 minutes. Blowing up my raft took over 20 minutes and it didn't even make it full and the cigarette adapter was hot to the touch. I have a $10 pump from Target that does the same job for less. If you are looking for power to fill a raft or something larger, like a car tire, look elsewhere. It's too much money for so little results.

I was looking for something I could put in the back of the truck and have the power to be able to inflate tires with ease. This was exactly what I was looking for. It safes a lot of time when you need to put air in the tires instead of dragging out the big air compressor. It is small but, strong and not very noisy. I like that you can either blow up tires or other items. I like the ability to either flip one switch and inflate tires or flip both switches and be able to inflate air mattresses or any type of a sports ball. I would recommend this to anyone who is in need a small but, powerful air compressor that is capable of pumping up a tire in a short amount of time.

I own it about a year. It works now as it did when I received it.I use it almost once a month or little more. So I would onlyinflate 2 - 3 lb more. If I did not have it I should have visited togas stations (and pay) for the same thing using a huge compressor.So I would say it works like a "little giant" brother.Just be careful on the gauge reading. You may have to calibrate witha standard gauge. I always check psi with another gauge.

This pump has been a LIFESAVER on more than three occasions.We've kept it stored under our back seat and in the original box - and pull it out when needed, either for our tires or for the unfortunate stranger who needs a quick pump!The cigarette lighter power cable is durable and all of the electronics on the appliance have lasted just fine since we purchased and used for the past 8-9 months.We recommend this for every car! You never know when you'll need it!

Turns out you can get a total of about 7 pounds of pressure in a standard car tire before it overheats.After it blew multiple fuses 3 months in I finally decided to try again at the 1 year mark. You cannot get more than 7-10 pounds of pressure before it overheats and starts letting pressure OUT of your tires.Yes I read and followed all the directions exactly.Very disappointed.Oh guess I should mention it's great with ATV and mower tires. If you're by the vehicle when they need inflating.

Tried to inflate a kayak, stood sweating in hot sun for over an hour while others were in the water. Until someone came along with a manual pump and I was up and running in about 10 minutes. Returned this sucker...

Works OK. Not as fast as it claims

Used it for blowing up an airmattress and it stopped working after my second time using it
