Question: Can you also use this unit to deflate?  I see references to that in the reviews, but no specifics provided.
Document: I hooked this up on my boat and inflated Big Mable in no time (a couple minutes). It will also take the air out of Big Mable fairly quickly. But there is no better way to inflate a towable than on-the-go and this unit will get the job done! There is a high pitched  sound, but it will only be on maybe 2 minutes while inflating, so it will not bother me in the least.
As I read somewhere here, the instruction does not tell you why you need to use one finger to a small burning hole in order to inflate properly. (Not comfortable)Not only does a high pitch whistle when is blowing, but also the bearings are making awkward noises after only 10 uses.I use it for a 14 feet inflatable boat and also for camping mattresses.
I bought the RAVE Sports 12V High Pressure Inflator/Deflator... it worked perfect to inflate and deflate a huge raft in minutes.. This is a must buy and great value
Blew up my SEA DOO 6 lounge in 17 price , its a little loud but a small price to pay for the results. I will update as I use it.
This pump is pretty small. It actually seems pretty cheap when you hold it. It inflates pretty fast i got them to inflate tubes for tubing on rivers. The only issue i have is that the unit heats up pretty fast and pretty hot so its a good idea to let it rest/cool between inflating tubes. If this unit decides to break in the future I think i will go with something cheaper.It does beat blowing up tubes by mouth and almost blacking out.
So, over last month we took the float out twice and both times this pump was amazing. But...the last time, my second use of the pump, it made a weird noise mid inflation, spit out some black plastic and then ran like crap afterwards...so loud I couldn't even use it anymore and the performance was shot.
This 12 volt inflator works better than I had ever hoped for! It does in one minute what I can do with a foot pump in 15. After use it is easy to wrap it all together and back into the box for storage. I did leave the extra tip pieces home, but that shouldn't make much difference. If there is a negative it would be in the length of the battery cables .......they could be a few feet longer.
I was disappointed when I took this out of the box. It is small and feels cheap. Then, I turned it on. Unbelievable. Even after reading the good reviews on here, I didn't expect it to work so well. It is by far the fastest pump I have ever seen - much faster than air compressors used for cars.
Just bought a new 2 person tube. This inflator blows it up in 5 minutes. We no longer have to blow it up before we leave the dock. We blow it up in the boat and then deflate it when we're done.
After reading reviews on other 12V pumps, I was leary to buy any. However, the reviews on this one were dead on. It is loud, but I've used it to blow up several inflatables without any problems. It hits a slightly higher pressure than many of the others, and the connections and power cords are all long enough to get around my boat.
Answer: yes
