Review on Efficient and Reliable: Coghlan's Electric Air Pump for Quick Inflation by Daniel Russell

I bought this pump to inflate a large air mattress that I will be using for motorcycle camping. I installed 12 volt outlets on all my bikes so I no longer have to use a D battery powered pump. I figured a 12 volt pump would be the best solution. How it is. The pump itself is tiny, much smaller than the plug-in pump that came with the mattress. Small is good - takes up less space on the bike. The pump has an on/off switch - not essential but nice to have. The pump comes with a 10-foot power cord, which should be enough. It has a standard car plug (cigarette lighter). I replaced this plug with a smaller one that fits into the accessory sockets on my bikes. (If you do this, be careful of polarity. The pump will definitely inflate more when properly connected.) My airbed is nominally 72 inches long, 60 inches wide, and 22 inches high - queen-sized. But at almost 2 feet tall, it takes a lot of air to inflate it. The Coghlan pump can inflate and fill this mattress very firmly in less than 10 minutes. I see no need to "pad" the mattress, which is very good. It actually takes longer to deflate a mattress with a pump if you really want to flatten it. About 15 minutes. Although the pump worked hard and for a long time, it did not heat up. It drew a maximum of 4 amps (48 watts). Its output noise was in the dustbuster range - acceptable. The only thing that caught my eye was the fact that the adapter that connected the pump to the mattress fill hole didn't fit snugly. I can't blame Coghlan for that. A few wraps of vinyl tape around the adapter tube increased its diameter by a few thousandths of an inch and provided a good seal. The problem is solved. How long does this pump last? Good question. I hope this lasts a very long time. I also hope it doesn't stop without warning. It can make for an uncomfortable night! But no matter how cheap these pumps are, I could buy a spare, and no matter how small they are, I could pack it just in case.
