Laurel Posted June 9, 2014 Report Share Posted June 9, 2014 (edited) I would like to use the auxillary AC outlet in my SEL to pump up an inflatable kayak. The pump is http://www.costco.ca/AIRHEAD%C2%AE-SUPER-PUMP%E2%84%A2-Air-Pump.product.10334327.html The pump says something like draws 7.1 A/917W, and the owner's manual says maximum 150 watts for the plug in receptacle. Is the pump going to draw too much power to use with the SEL? Edited June 10, 2014 by Laurel Quote Link to comment Share on other sites More sharing options...
ArizonaEnergi Posted June 10, 2014 Report Share Posted June 10, 2014 Yep, with 917 > 150. Quote Link to comment Share on other sites More sharing options...
Laurel Posted June 10, 2014 Author Report Share Posted June 10, 2014 Thanks for the answer. I guess I will have to use a foot pump. Darn. Quote Link to comment Share on other sites More sharing options...
ArizonaEnergi Posted June 10, 2014 Report Share Posted June 10, 2014 Why don't you see if a high-volume 12v pump is available. Another possible alternative is to buy an inverter that will run off the 12v outlet, but you would need to make sure all those amperages match up too.

fotomoto Posted June 10, 2014 Report Share Posted June 10, 2014 Why don't you see if a high-volume 12v pump is available. I had this same decision when we went camping and decided on an ol' fashion manual pump. It was a high volume design, cheap, and worked perfect for air mattresses. I also found it incredibly handy for stoking a weak campfire into a hot blaze within seconds (literally). Quote Link to comment Share on other sites More sharing options...
kostby Posted June 10, 2014 Report Share Posted June 10, 2014 How big is the kayak, and how patient are you?The C-MAX 12v Tire Mobility Kit includes that small compressor and one adapter. The compressor does shut down automatically when it gets warm after about 5 to 7 minutes of continuous (auto tire) inflation. Once it cools off, it will run another 5-7 minutes.

Laurel Posted June 10, 2014 Author Report Share Posted June 10, 2014 Kostby that is a brilliant idea! Thanks. It is a Sea Eagle catamaran kayak--pretty big. The foot pump works well but on a hot day it is tiring. Quote Link to comment Share on other sites More sharing options...
fbov Posted June 10, 2014 Report Share Posted June 10, 2014 Two thoughts... I have a Coleman air mattress pump, doing a similar job, that runs on 4x D-cell batteries and is basically just a low-loss fan, what you want in a low pressure, high volume operation. No way that pulls 150W... Current/power ratings come in two kinds, sustained and transient. Given 4 D-cells can do the job, I suspect this pump is rated for transient power. Easy to test with a $20 device. Do a search for "electricity usage meter" and you'll find a bunch of small devices that plug into an outlet, and measure the power draw of whatever you plug into them. Measure the pump's actual power draw when inflating the kayak at home.- If it stays below 150W, you're golden for this application.- If it blips higher for a very short time, perhaps at start-up, you may well be fine- if the current draw rises as the kayak inflates and back-pressure builds, you're out of luck when it hits 150W...

Adrian_L Posted June 12, 2014 Report Share Posted June 12, 2014 Why waste money on D cells when you can use the car battery? There are a whole bunch of cheap 12v air mattress pumps out there. Ours plugs into the 12v socket and it takes about 5-10 minutes to blow up a queen sized air mattress. We've had it for a decade and it can't have been more than $15. The nozzle changes size too--handy for that big mattress plug. Quote Link to comment Share on other sites More sharing options...
fbov Posted June 13, 2014 Report Share Posted June 13, 2014 The main reason is that I don't always park within feet of my tent, and am loathe to pull the mattress out of the tent to fill it. Other reasons are fast and foolproof. It's a Coleman air mattress, so this pump mates with an oversize port you can't access with the cheapys. It inflates really fastm batteries last years and there's zero chance of overinflating. Have fun,Frank Quote Link to comment Share on other sites More sharing options...
