Cost effective dc air pump

I tripped across this while on ebay and was wondering if anyone out there has tried one of these. I use a cheapo airhead pump modified with a long a$$ 10awg cord and a hose with a leafield fitting - but this looks nice and will do high volume AND high pressure automatically.

Thoughts?

I would be very skeptical that it provides both high pressure (not specified) and volume. At 11 psi, the pressure is far too high for rafts. Plus, it's expensive. $40 seems typical for a decent blower.

Blower and pumps are somewhat different in their function.

I haven't found too many dc pumps out there in the $40 range...but maybe I'm not looking in the right place. Moreover - the fact that it can handle higher pressure makes it great for IK, SUPs, etc.

It states that it will use the low pressure/high volume pump up until 3 psi then switch over to the high pressure/low volume pump. There is an analog gauge as well integrated into the pump.

This listing seems to have more detail that the first one I posted - but it's the same pump.

I've got one I've been using since 2010. It's awesome. I use it to blow up my 15 Sotar to 3 1/2 or 4 psi. Works so well, my friend bought the cordless version. He gets about 3 boats per charge.

Switches to the high pressure pump at 3 kpa, not psi.

Caution on high pressure for IK's. The drop stitch does need 8-10 psi, but the chambers are normally 2-2.5.

Wow! Really? So at under 0.5PSI is switches to HP? That seems like a waste of a stage and would drastically reduce the volume it can push.

Per the link:

"When the pump starts it will be on a HIGH VOLUME (Turbine) pump until the pressure reaches 2-3 PSI. Then the pump will automatically switch over to the HIGH PRESSURE (Piston) pump and inflate the boat to its set pressure. Once reaching the set pressure the pump will automatically turn itself off."

I'm wondering if one of those cheap 12v inflators combined with a K40 for finishing would get the job done on a boat with a high pressure floor.

or would the cheapy just burn out?

how agonizing would it be to do an entire 14 foot boat with a K400?
