extending chord?

Hi,
We just purchased a:
SCOPREGA S.P.A. 12 HPP High-Pressure Inflator for our kayak and dingy.
“This compact 12V adjustable pump inflates up to 11.7 psi, and automatically shuts off when selected pressure is reached.”



We would like to extend the chord with the alligator clips on it to reach our batteries. We would like to extend it by ten feet. My question is will this compromise the pump? Would we need to add heavier wire?

All I see on the box so far is it uses 15-20 amps.
Not sure how long the chord is now. Could be 10-15 feet.

Thank you,
Chip

I would go with 10 gauge and install some type of plug with fuse protection as the clips will be a PITA and kind of easy to make a mistake

If a dirty bottom slows you down what do you think it does to your boat

We have tried using the pump to deflate our kayak and we could not get a fitting to work. We mainly got it for pumping up the stuff anyway. But while using the pump we had to put the leads down a hatch and onto our 400 amp buses (post + neg). I could see someone pulling on the pump and one of the clips pop off the bus and get welded to something,. Not a good thought.



I like your idea as it seems a Cigarette lighter adapter would work better with a longer chord. Only thought about that is will it carry enough current to supply the pump with the needed amps and with a longer cord? I guess a spot light must use 15-20 amps and the one we have has a Cigarette lighter adapter.
Thanks,
Chip

I agree with the switch that Tommays showed. I have used them and they can handle the load. Fuse the positive near the batteries as well.

Great stuff here, thanks.
We will proceed and set the wiring up for the pump that way.
