Car Inverter on boat?

(malibuboarder75)

I have a 95w appliance that I want to run on the boat. Will a 100w car inverter work. Is it safe?

Blender?

Actually a pump.

Details!!!

I've used a small one to power my laptop, had no problems.

Does it say how many Amps DC it draws. If the 100w inverter has a breaker that would trip in case of over load, then give it a shot.

That is what I dont understand. The pump says 95W and 1.33 Amps. If P=IV, then this is wrong. Because at 110V, the power should equal 146 Watts. Everywhere states that this pump is under 95 watts. As far as power inverters, they are rated on watts not amps. So wouldn't a 95w amp run on a 100w continuous inverter?

I run a 500w inverter hooked to a breaker so things won't blow fuses

if you haven't purchased one yet....just go bigger
woo hoo

check out the chart on the optima battery site
cant find the link....I have it bookmarked at home

I will post it later

it pretty much tells you how big of a inverter to use based on appliance used

is there any danger of running that large of an inverter on your boat? would a larger alternator be a requirement?

my stereo guy didnt think so
I power a 4 hp vacuum/blower/inflator
blows up a 2 man tube in no time!

i just forget to turn it on, so it will "charge"
takes a little bit to "charge"

I am actually thinking about going with the dida-2 instead....for the boat
the dida-4 is a beast

Leo, that is not enough margin. There will be a giant spike on start up, for any electric motor. Go bigger. In fact get one rated at over 1000 watts so you can run a blender. I paid $75 for one from Costco that is 1750 watts.

what I have is a 1500 watt inverter
the Cobra cpi 1550

do teh costco one. I'd get way higher than 100watt if you are running a 95 watt applicance.

Give some room for variance...and other thigns you may want to run.
