Hi,
I’m writing because I’m the owner of two iSUPs and I’m having trouble getting reliable data on electric pump durability. We bought two 12’6″ iSUPs last summer. We’re not that young and don’t relish the hand pump option, so I did my research and we purchased 2 electric pumps similar to your #4 Tower pump reviewed above. Our requirements were: 20psi, 12volt, 2stage, auto-shutoff, and durable. I found that various vendors/manufacturers were selling same pump (the one you review above by Tower) just re-branded and in different colors for various iSUP manufactures (Tower, Airhead, Connelly, OBrian, Aqua Marina, etc.). We bought two pumps because the specs said they would overheat and if used continuously for more than 20 minutes. It takes 15-20 mins to fill our boards to 19 psi. This wasn’t an issue as they were selling for approximately $90 last year (well worth the price). We loved them, and they did a great job.
However, last week one of the pumps stopped working during the compressor stage. The O-rings in the compressor gave out. We’ve only used it about 20 times (the other one is still working fine). I contacted Airhead, the dealer of my pump, and they will honor their 1 year warranty (I’ve had the pump for 11 month’s). I’m still worried about the quality of this unit, so I went back online to research again. There isn’t very much technical/reliability information out there on 20 psi pumps, and the vendors I’ve talked with don’t even realize these re-branded pumps are all the same. Yesterday I called Seamax regarding the #3 pump you reviewed above. The exterior is obviously quite different from the others and it uses digital gauges and controls. Their rep assured me that their pump was very durable, but when pressed didn’t know the term of their warranty, the inflation rate, or technical information regarding the compressor.
I was hoping you might have more information on this topic or could point me in the direction of someone who did.
Thanks for your time
