Jamie I was talking about the truck being on but not in gear

 

I have brought my Blender camping and mixed up some good Mojitos out in the middle of no where!

 

Thank you! about time someone actually used math for this
It's simple as I=p/V

When the truck is in park the inverter will produce 400 Watts

I=400/12
current= 3.33 amps
This will get you well... not much. a charger, coffee pot. Probaly the most usefull thing is a work light.

as far as having 2 batteries:
2 batteries do not equate to more juice. The battery's would be wired in parallel which would give you the same 12V. If they were to be wired in series the 24V would fry your truck. If the truck is running the alternator charges your battery anyways. I sure hope your alternator can charge your battery faster than your 3.3Amps degrades it.

my circuts fail.. disreagard that

 

the inverter will shut off when the voltage gets to low. there will be just enough power in to start the engine. i mean just. every item has a power rating on it in watts. it is stamped right on it. there is a lot of stuff you can run on the inverter. most stuff would not go over 150 watts. the only items you can't run is anything with a heating element or a electric motor, except a drill or dermal. as for how long the battery will last, if you are just using it to power a charger for a phone or to run a radio, no problem for over night. a small tv and dvd, several hours.

 

I'm thinking of adding a second battery and a true sine wave converter, so that I can run two laptops during trips, etc. I have no idea to accomplish this goal and would like lots of input on how to do this! Thanks.

 

BLender!!! For those cold drinks!!!!!
