1) Maximum pressure
One of the first things to check is the pump's maximum inflation pressure. It must be capable of delivering the pressure required to inflate the boat.
Models delivering a pressure of 20 psi are ideal for inflating float-tubes and flatforms. They are often sold to inflate paddle boards, and it's in this very department that we'll find them.
2) Air flow
Another criterion to check is the air flow rate, because the smaller the flow rate, the longer it will take the pump to reach the desired pressure.
For a PVC float-tube, with a 70L/min pump, inflation time is around 3 minutes. A Dropstich model takes around ten minutes.
3) Electrical connection
In most cases, at the water's edge, the car's 12-volt cigarette lighter socket is used to power the pump.
Check that the pump can be connected in this way, and that the cable required for connection is included and long enough.
4) Matching ferrules
Before buying a pump, you should also check that it comes with the right fittings for your boat's valves.
It's best to take the pump with its tips at the same time, as it's not always possible to adapt a tip from one brand to another.
In general, the SUP type tip is used to connect to the valve.
5) Programming
Finally, for your convenience, we recommend a programmable model. In other words, once you've programmed the desired pressure and activated the pump, it will stop automatically once the set point has been reached, and maintain the pressure until you close the valve.
So many criteria to consider before buying an electric pump to inflate a float-tube.
