Question: Can replacement pumps and/or AC adapters be purchased?
Document: Purchased for tent camping. Tried out before trip and all was well. While camping air pump died 1st night! Had to sleep on a mattress that was 1/4 full. Supplier informed us that Aero had a batch of bad pumps that went out and replaced it for me but took 4 weeks. Nice product but test more then once before you use it.
The pump is VERY fast, too. It takes 1 min 20 sec to get it to the firmness that we like, which is pretty firm. The valve allows it to be used with several alternate types of pumps and on an extended back country trip, I would recommend taking a backup of some kind, just in case.In all fairness, the 1st one we got did lose about 1/2 it's air in 4 hrs. Amazon had a replacement one on the way the same day that I requested an exchange.
Over the years, I have purchased several Aerobeds (still own them all), mainly the camp and travel beds, and they have been wonderful. The mattress is very comfortable and durable. Normally, I will charge each of the pumps a few days prior to use for about 12 hours. The cord that connects to the newer pumps contains an indicator that turns green when the pump is fully charged. I still use an Aerobed and original pump for camping trips that I purchased about 10 years ago.A few important items:1) Be sure to charge the pump for 24 hours prior to first use.
Bought two of these, the pumps don't work properly. Even after plugging in to the wall for 24 hours one didn't work, and you can't inflate simply by plugging the pump into the wall while inflating, it needs to charge ahead of time. Poor design.
This is critical.2) Prior to further uses, charge the pump for 12 hours. This is also critical.3) If the pump is not charged, it will not work even if it is plugged into a wall outlet.4) However, the pump will work when plugged into an automobile's 12V outlet.Overall, the beds are easy to set up, inflate, deflate, and store in the generously sized supplied bag. Unlike some of the other reviewers, I have had good experiences with the beds and the pumps.
I have had a couple of these for several years, but apparently rats got into the attic storage and thought the polyvinyl tasted good. They chewed a large unrepairable hole, so this was a replacement. Best air mattress i have owned.
I have gotten a lot of use out of my Aero Sport  bed. My valve did break once, so I called the 800 number to see if I could get a replacement. Even though my bed was out of warranty; I only paid $8 to get a new valve.
I bought this thing new from amazon.com and it just doesn't work. After inflation, it's difficult to put the cap back on without losing a whole bunch of air, and then, it just deflates overnight. I was going to send it back for a replacement but it's not worth the effort, just threw it in the trash. A waste.
I just checked and after 2 1/2 months in the garage the pump had enough charge to do about a 2/3 to 3/4 inflation - I believe the instructions require  a little more charging maintenance, so I would say this is pretty good and as expected. I would like to have a hand pump to finish a final inflation to firm up the mattress or in case the pump doesn't work (but there is none that I know of). the Aero battery pump did considerably better than the old colman mattress & pump it replaced (FYI coleman pumps do not fit this mattress and the odd Aero air inlet configulation does not match any hand pumps I've seen).
The Aerobed held air for an astonishing 45 minutes before deflating.I want to get my MONEY BACK, and, honestly, if the people at Amazon had to spend five nights on my parents' hideously uncomfortable twin hideabed because of a defective product sold by their company, they would be completely on my side in this matter. Understandably, I do not want to take a THIRD chance on getting a defective replacement Aerobed.There is no visible reason why these two Aerobeds failed to function. We followed all the instructions. The bed inflated beautifully.
