Does anybody know how many amps the 110V electrical outlets can handle? I'm wondering if I can run a Coleman air bed pump from one of these? Is it about the same as the 12V plug or more/less? I want to buy an air pump for camping, but I also want to be able to use it around the house, so 110V version is preferable it the truck can run it.

 

Thanks.

The alternating current (AC) accessory power outlet system consists of the accessory DC/AC power inverter module and the accessory power receptacle – 110 V AC. The accessory DC/AC power inverter module converts 12 V direct current (DC) battery power to 110 V at 60 Hertz (Hz) AC power to operate AC powered devices. The accessory DC/AC power inverter module provides up to 150 watts of power. The accessory power receptacle – 110 V AC provides the usual connection for AC powered devices.

The AC outlet is a joke. I plugged my Makita charger into it, and it tripped immediately. Why even put on in there in the first place?

 

You can plug the pump in and see if it trips.

Okay. Here's the equation:

 

P=VI (Power (watts) = Voltage (volts) x Current (amps))

 

With the numbers provided above, the available current (I, in amps)

should be...

 

I = 150/12 = 12.5 A

Don't know the specs but can tell you I tried using my 400w invertor to plug in a pump for an air mattress and it cut out immediately. I doubt the factory 110v plug will allow you to run that pump.

So, it looks like the 120V pump runs at ~250 watts after the initial ~450 watt surge. That won't cut it. I guess I'm going with the 12V pump.

12.5 amps should be plenty for most household appliances, even a microwave or a small refrigerator. I'd imagine, though, that you want to pull this much amperage only with the alternator turning/engine running.

Maybe I'm wrong, but the outlet is 120v, correct? So wouldn't it be I = 150/120, or 1.25A?

This is 120v AC, not 12v DC....

You are correct sir! :)

 

And on top of it from my experience with the outlet, it looks likes its a modified sine wave inverter and not a pure sine wave inverter. This means that there are certain things like some chargers will not be too happy on that modified sine wave.

You will be fine, I have done this many times with no issue.

Nerd, maybe but correct, no.

 

Your formula is correct, but you solved for the 12V amperage and not the 110V amperage. Since the pump in question is a 110V device, it's THAT amperage that will dictate whether or not its current draw is too much.

    • probably won't get a response from that user, as they haven't returned to the site since making that one post.  users don't (at least I don't, and I haven't seen any setting which would notify me via say, email) get any notification other than going to this site, and checking if they got a response on their thread...
    • Thanks - I wasn't quite caffeinated this morning. 2:1 makes sense, turning the crankshaft 360 degrees will turn the cam 180 degrees, and had I done that, the cam's dot would be at 6 and the crank's at 12 again.   I went ahead and took the sprocket off anyway, aligned everything dot-to-dot including the balance shaft just for s&g. I'm glad I did because I discovered no Loctite on the timing sprocket bolts. Maybe it's not required, but at only 20 ft-lb torque spec, those bolts aren't in there very tight. Cleaned and reassembled with some thread locker and torqued.   A general observation: Less is more with RTV. If a little doesn't stop a leak, a LOT probably won't, either. RTV is thinly veiled revenge, in a tube...      
    • The timing marks are ok, that is #1, you can turn it over until they line up and it won't change anything, the crankshaft turns twice for every camshaft revolution, I have always set up SB Chevs as your pic shows using a straight edge
    • Someone's been here before.... There is a receipt for a 3-piece timing set, purchased earlier this year.   Is this picture something, or, nothing?   I have the timing cover off and my crank is perfectly TDC and the keyed gear's locating mark is dead on 12 o'clock.   The cam gear locating mark is also at 12 o'clock. Now, I'm not an expert, but all the install guides say the two locating marks should meet and be perfectly aligned when installing a timing set. The mark on the crank should be dead on 12:00 and the cam gear's mark should be dead on 6:00, and both marks should be perfectly vertically aligned.   I believe the timing gear is keyed or has a dowel that ensures it can only be installed on the cam in one position, so I have to believe the cam is out of phase somehow. At the very least, with a triangular bolt pattern, it can only be installed in one of 3 different positions.   Before I pulled the front cover, the truck was running alright, no service engine soon lights except an occasional P0172 / rich condition. Timing -16 timing at idle (should be +16), and total -35% fuel trim, two conditions I haven't been able to figure out.   In related news, my injector tested pretty well, wasn't leaking, but I had it rebuilt anyway, and it's on it's way back to me.         Along with this discovery, the good and bad:   Good: The oil pan seal appears undamaged.   Bad: -The timing cover has been reused, and the positioning dowels have been broken. That could explain some of the leaking. -Some kind of white paste or grease was used to try to seal the oil pan seal and timing cover (since wiped off..). -Then, someone globbed silicone all over the front of the cover and also buried the ckp sensor in it. But, they didn't put any inside the cover or use RTV to try to seal the oil pan seal with the timing cover (good).
    • The guy that owns K&P filters last I checked in with him has over 300,000 miles on his Dodge base Hemi using his own 35 micron absolute stainless mesh filter from its first oil change.    The GM study I've posted a dozen times shows the relationship in engine life based in multiples of base units, not miles or years. That is the base unit is the number of miles the motor ran using the reference filter efficiency.    The above two paragraphs dismantle anecdotal arguments IF one changes oil often enough to prevent particle formation and the motor is in otherwise good shape. That is not full of silica (no air filter) or suffering a metallurgical issue that is not part of the lubrication discussion. Poor heat treat in example.   Data from UOA's I've reviewed from more than a few engines can show remarkably broad variations in oil cleanliness using the exact same filter over the course of an engines life.     Lastly there is the common sense of it. Wear debris WILL circulate the engine BEFORE it ever sees a filter in route to that filter and WILL harm the pump which NEVER sees filtered oil.    Alpha question then becomes, given the facts, how long do you believe is a reasonable service life from a vehicle you are certain you will not pass down? That is the junk yard will be it's resting place when you're done with it? (the moral issue most don't care about).    Omega question is then how diligent are you prepared to be in general mechanical, air & oil maintenance? Preventing particulates and keeping them sufficiently dilute; preventing the precursors from generation, amalgamation and precipitation.    If I get a good look at the engine bay of a vehicle I have a fair idea of the owners commitment to the inside of the power train. That 30 micron WIX is still more efficient than a sieve.
