Review on Awesafe 20PSI Electric SUP Air Pump | 7800mAh Rechargeable Battery | Inflatable Paddle Boards | High Pressure | Dual Stage Inflation | Auto-Off | Deflation Function | AC Adapter & 12V DC Car Connector by Steve Jones

If you are looking for a battery powered ISUP Pump this is perfect. It's capable of inflating two boards to 15psi (10ft - 2in and 11ft) non-stop and the battery gauge was at 59% allowing it to inflate a third board after a pause. Connected to DC, it is only slightly faster to inflate. The 11 foot board was 11:40 versus 10:50 and the 10 foot board was 10:10 versus 9:25 (battery versus plugged in). The battery is constantly discharging, so I think the battery should be 30% or more even when connected to the mains. I have an Outdoor Master pump and the time it takes is 11 minutes -8:10 and 10 minutes -2 inches -7:40. Both can do 2-3 boards in a row, so it's all about speed (30% faster). compared to battery performance. several times the car is not close to the starting point The two pumps have a strong family resemblance as the hoses are identical, as is the inflation characteristics, as well as the note that the pump must rest for 10 minutes after 30 minutes of operation.
