Inverter fault light

So, for christmas my old man got me a 400w inverter and a small (4-cup) coffee pot. ...I'm a coffee person, regardless of if I feel I need a cup or not I love the taste of good coffee. (Drip-brew isn't great, but it's better than peelot and others!)

I know these coffee pots pull quite a bit to power the heating elements inside, but he and I were both under idea (after some research) that the inverter would support the use of the coffee pot.

That being said, I'm a company driver. All I can really use is the 12v plug and I can't adapt the truck in any way to suit the inverter "better."

Here's my issue:

I plugged the pot in and started to attempt to make coffee. Within two seconds of the coffee maker coming on, the "fault" light came on and I saw the in-cab light (the only other thing I had on.) dim. Immediately I pulled the power on the inverter and things restored to normal. There's no noted damage to the truck itself, and yes I had the rig running. I had a feeling that the batteries alone weren't going to power the coffee maker.

My assumption, from this, is that the inverter can't supply enough power OR that the alternator isn't enough to supply the needed power. (SNI told us that there's a limit on the inverters we can add, I believe I am within that level.)

I am going to use the pot tonight at home to make myself a brew and take it with me. It's possible that there's a short in the coffee maker too, but I'll know more later.

Right now, I'm just looking for some advice on the matter. I would, and am willing to, buy the roadpro coffee maker and not use the inverter. (But, Christmas gift.)

Thank you in advance and I do apologize if this has been resolved and asked before. I did do a quick search, but found nothing applicable. I'll be checking this when I shut down later tonight, I have a run leaving soon.

 

Yeah, as I unwrapped it I did ask him if it'd work. He claimed he'd used a similar setup and showed me some documentation somewhere but I did have the sneaky suspicion it work not work.

My understanding is that coffee makers use 100w per cup give or take for any addons. Otherwise this one is very basic, just an on and off switch.

Cest la vie. That sucks. Oh well, I do like percolated coffee. I can use less grounds since it's stronger.

Thanks you two!

 

Ah well crud. There goes good coffee. Heh. SNI doesn't do inverters that are hardwired in unless you're lease or o/o I believe.

Im home often enough to where I should be able to make my own though. At this point I'm considering leaving SNI after my 6 months newbie purgatory are up. That's what my gut tells me at least.
