Review on 🔌 Tuomico Max 20 PSI SUP Electric Air Pump with Dual Stage Inflation & Deflation, LCD Digital Electric Pump | 6 Nozzles | for Stand Up Paddle Boards, Boats, Water Sport, Inflatable Tent, Yoga Ball by Justin Pavelko

I bought this pump mainly for low pressure inflatable boats that inflate to 0.5 or 1 PSI and also for SUP that inflates to 15 PSI. When I first inflated my kayak to 1 PSI, the pump worked great and I was completely happy with it. The pump is easy to use and displays the current pressure when filling. I then filled up my SUP and the pump worked well enough, although it is quite noisy and I can manually inflate the SUP just as quickly as the pump. Now every time I try to blow up an object at 1psi. Inches, the reading quickly increases to 1 psi. inflation. This pump appears to be identical to many of the others shown here under various brand names and I hope this is not a design flaw affecting them all. I have contacted the seller and will update this review if the situation improves. I'm totally disappointed at the moment. UPDATE: The seller was quick to respond to my concerns and is taking steps to help me. I've now used the pump a few more times and while I have basically the same problem as before with my low pressure boats, it works fine with my SUP. I'm changing my rating from 1 star to 4 stars because the seller was very responsive and I now expect a positive response.
