Outdoor Master electric air pump
The Outdoor Master pump is sold for inflating paddle boards. As these boats are very similar to float-tubes, with its maximum pressure of 20 psi, it's perfectly suited to inflating them.

This pump is very simple to operate. Simply enter the desired inflation value, and press a button to start inflation.

Real-time pressure is indicated on a digital display, so you can quickly see how far along you are. Once the pressure has been reached, the pump stops by itself, and all that's left to do is close the boat's valve. Pressure can be displayed in Psi or bar.

Inflation takes place in two stages. A first stage with a maximum flow rate of 350 l/min, to form the boat, and a second stage with a maximum flow rate of 70 l/min, to reach the selected pressure.
It can also deflate a boat, making it easier to fold. To use this mode, simply change the position of the hose that connects to the valve.

The pump is supplied with several nozzles, including those required for inflating float tubes.

A few precautions
Even so, the pump is fragile, and care must be taken. One of the first elements is the connection between the pump and the hose, which is made of hard plastic. It should not be screwed on too tightly, and of course, care should be taken when transporting it.

The other point is to make sure that the air intake is clear, so that no grass or sand gets in. To achieve this, I recommend placing the pump on a bag or on the boat when in use.

The pump features a cooling system, so you can inflate several pieces of equipment in succession without overheating and having to wait for it to cool down before using it again.
This fan is located underneath the unit, so it must be kept clear and unobstructed to ensure proper operation. Isolating the pump from the floor ensures air circulation.

Finally, the pump does not come with a storage bag. To transport it and protect it from pollution, it's best to find a bag.
My opinion
After a year's use, I haven't noticed any malfunction of the Outdoor Master pump, nor any loss of power or speed.
The pump is quick and easy to use, taking just seconds to set up.
So I recommend this pump, because it seems reliable and it's really practical, for inflating a float-tube, a flatform, or a paddle board.
