Hi everybody:
I travel with a 25'5th.I'd like to
know,provided that my battery in my unit and truck is charged can I use the microwave for a short period of time,just to warm up something
at the truck stops?Are there any precautions to
take before I run out of juice?As always many thanks for your help........araucano.

HUH?

Every microwave I've ever seen in an RV runs on "house current" (110-120 VAC). So, unless your fiver is equipped with an inverter (and you don't mention this fact in your posting) to convert to AC voltage from 12 VDC, the only microwaving you're going to be doing is wiggling the "pinky" on your hands.

Microwaves generally pull enough power to require a pretty substantial inverter and a pretty good sized bank of batteries. I think most of them shut down if the battery voltage gets to 10.5 or so.

We have a 1100 watt inverter that is mounted over the fuse box in engine compartment of PU. I used jumper cable clamps to hook up to batt. posts when in use. I plug in an extention cord to camper or TT to use micro. Works fine. I don't leave it on except to use micro. I don't want to waste the truck batts.

a min blast on the microwave iwll owrk but bare in mind that at 10amps at 120vac is just over 100 amps at 12VDC so make sure all the feed connections and cable are up to the task ! at a min use # 4 cable and keep the 12volt side as short as possible.

I am running a 2000w inverter, 4.0 cabling and T-105 batteries. It is all my setup can handle running the microwave. My battery voltage will drop quite quickly to 11v. A large micro pulls mucho amps.

We also have a 2000watt inverter and 4 6-volt batteries, and it will run the microwave, but it sounds really weird and drops the voltage meter down almost instantly!!

I'm thinking if you only have one battery, it's a no go.

drawing 20~30 amps off of one battery is no big deal , drawing 140 amps off one battery for more then 30 seconds is going to kill it in a very short time frame. Like stated above if you have a bank of batterys that you can divide the 140 amps across each of them will supply equal amperage to add up to the sum .Most RV 12 volt batterys are around 70~80 amp hours , you can only use about 30% of that stored energy before the voltage drops off to the point the inverter shuts down (24 amp hours basicly)

The size of microwave makes a big difference. Ours is about 750 w. If you have a big one it will be a lot harder on the batt.
