Operate jetze two identical pumps (have equal-ordered). Now I can my boat (Intex Excursion 5) with accessories completely inflate to the required operating pressure and (at least so important exactly) pumping again !! It still remains plenty of reserve if success occurs a little glitch (eg Schlauchg slips off). My hand pump I can mothball actually, but -na ja- safe than sorry. The battery lasts a long time and ausgesproche by the noise during the operation does not disturb me of skin. According to other reviews I had the device actually imagined even much louder than it actually is. If you consider that you probably ie pump operates mainly outdoors, the noise is negligible anyway. For me personally, an absolutely amazing part without ifs or buts. If you want to order the unit should keep in mind that really only battery operation is possible, the power adapter and the 12V Zigarrettenanzünderanschluss not allow operation but only charge the battery. For me, no problem, but you should consider that.
