Power inverter capacity

[Fishwiz]

First off I apologize if it's been shared, but I couldn't find it via search.

I have a Bighorn level 2 with rambox. It has 3 power outlets (dash, back seat, and rambox). Are they all on the same circuit so that I have 400 watts total? Or do I have 400 watts at each outlet? Or, are the two interior outlets on sharing 400 watts, and the rambox outlet has its own 400watts?

They should be all sharing the 400w. You could always circuit check one of the outlets when two others are under load and see how much draw you have left before plugging something else in.

It's 400W for all. It's enough to charge batteries, not enough to run anything.

It's in the manual.... All outlets share the total capacity.

The RamBox outlet is almost pointless for running any power tool other than a corded dremel or charging a wireless speaker. Couldn't run my shop vac or my corded impact drill....the only two things I really would have liked it for so far.

Can the inverter be upgraded?

Good question... Where is the inverter located?

I’ve wondered the same thing. The answer is almost certainly yes, but you’d want to ensure all wiring is sized appropriately, too.

Yes, in reality its just if you have lower powered devices that use a standard plug instead of a USB.

I have plans to add a larger pure sine wave inverter in the Bed once the Cap is installed.

Has anyone tried running a coffee maker off their inverter? We lose power frequently and the last time my wife wanted me to plug the coffee maker into the truck....I wasn't sure if it could handle it.

An average coffee maker will draw between 1,000 and 1,200 watts. So no you can't run it off the Hasbro Toys inverter built-into the Ram.

Before I bought a generator I used my 2,400 watt inverter to run my appliances, coffee makers, that I'd installed in my F250 Powerstroke. The cable to the battery for large inverters is usually 00 gauge for long runs. The cabling can cost as much as the inverter. You need large gauge DC cabling to maintain voltage for such high current applications, along with a quality amp-rated fuse.

I have a BlueHawk air compressor from Lowes. Its 120v that pulls 2.0 amps. Does that mean its 240 watts? 120 x 2 = 240. If so can I run it using my 400 watt outlet in the RAM box? I am weary to try it. Afraid it will blow a fuse or the inverter or burn up wire. Thoughts? Is my math wrong?

I ran a 3 gallon HF compressor with mine and it ran fine.

Try it...if you smell smoke...then we'll all know Your math is correct. P=IV

1875 watts... I'll pass.

But it's got built-in overload protection

To avoid overpaying for large gauge wiring I saw people using 20 to 30" Booster Cables from Amazon for inverters.
