decent inverter needed

just looking for suggestions on a decent (2000w) inverter i have a small heater im going to be using in the jeep this winter and it is rated at 120V / 60Hz, 12.5 amps and 1500 watts, so im guessing a 2000W continous power inverter should work (correct me if im wrong, electricity and me are not the best of friends ) im also trying to keep it under $150, thanks for any input its greatly appreciated



also if anyone has any creative locations they mounted theres post some pics please i am thinking behind the glove box for mine as i dont want to mount it under a seat ( pull my rear seat out and power wash the interior when i clean the jeep ever week or so) and under the hood seems like a bad idea for puddles.... any info here would be awsome too, thanks again!

12.5 amps at 120v is going to be pulling slightly more than 130 or maybe 135 amps at 12 volts out of the 12 volt battery where the converter gets its power. Even if the converter was 100% efficient, which it is not, it would draw 125 amps from the battery while providing 12.5 amps at 120vac.

1/10th the voltage, 12 volts, providing the same number of watts as 120 volts provides, means 10X the amperage will be required.

Powering an electric heater from your battery via a converter just isn't going to do anything but drain your battery in real short order. The alternator couldn't begin to keep up with it even with the engine running.

makes sense when you put it like that, ive been looking for a 12V heater but they all seem to suck, the blend door is cracked on mine and i dont have the money / time to fix it and dont want to go through another freezing winter without one lol, i get off work between 2-7am so its even colder then lol! i do have an optima battery (older one, pre-made in mexico) in my camaro i will be pulling out for the winter, think it would help if put it in the jeep for the winter? i dont plan on using it constantly, maybe just turn it on when i start the car and leave it on for 2-5 minutes while i let it idle and defrost the windows? i only have a 20 minute drive home from work but DAMN it was cold laster year


EDIT- also think it would help if i wired in something like a 1farad capacitor? that way it could run off that for a few minutes when i turn it on, then when the cap is low i can just turn it off..

Cheaper to invest in heated gear we sell for motorcycle guys. Just a small lead to battery and draws nothing at all. I have ridden with it plenty and it's amazing how little you can wear and feel like your warm in a blanket haha. Keep a real large jacket in the jeep. Get in and put on over what you are wearing haha.

hmmm those are pretty cool, ive been wanting an inverter for my jeep for a while for other things (laptops and such) so i dont mind spending a little on one but im going to have to convince myself on the 12v vests as i would need 2 (for passengers in the jeep which i have often)

All honesty so you know out of all we sell and have delt with. Harley davidson brand themselves make the best and longest lasting we have seen. It's like a battery tender lead to terminals. That or you could do a variation of this backwards for your heater haha

lol im not quite THAT ghetto, i have been wanting an inverter in the jeep since i bought it (i had a small one in my s10 that i traded in and used it a lot) and figured a small little heater would work perfect in the jeep for 2 months, i didnt think to do the math jerry did tho, 130 amps is quite a bit to be pulling, the most powerful 12V heater i can find is 300W tho and the reviews say it can barely defrost a window when held right up against it lol

actually i can afford an inverter + 10 farad cap, think that would be enough for short uses without damaging the altenator?

well ive been doing some more research on these bigger inverters and they seem to require 3+ batteries to operate at full , so i guess i need to find a good 12V heater, anyone have any experience with one?

A fully charged capacitor would be discharged in no more than seconds with that type of continuous draw. They don't help against steady current pulls, they only help to steady the voltage from surges in amperage being drawn... like momentary bass hits from an extraordinarily powerful audio amp.

A capacitor won't help in the least in this type of application, that's not what they do.

ya i have been reading nonstop since i first posted this and it seems like a pretty bad idea, going to try and fix my jeeps heater it might just be cheaper anyway lol!!! im PRETTY sure its a cracked blend door but not 100%, im going to try and diagnose it a little bit 2morrow and make a new thread for more help then, thanks for the help, saved me from wasting quite a bit of money

just going to post on here what i remember from trying to figure out the heater problem last year incase anyone has any good tips for diagnosing it,

1- i installed (recently) a new climate control panel so i have all new switches

2-both hoses off the core are hot to the touch after it warms up (but there is a weird splice/valve in one of them with a cap on it, looks exactly like the valve where you service freon in the A/C system) ill take a pic and put it in my new thread 2morrow because im not sure if it should be like that

3- hot air comes out of my floor vents (and i think my defroster vents, ill check 2morrow) regardless of where my switches are set, IE full cold with the system off, full cold with it on middle vents...)

4- i can see/feel the blend door actuator moving freely when i turn it from cold to hot and it doesnt sound bad at all

5- no leaks at all from the heater core

im ready to just bring it to the dealership to diagnose it if i cant figure it out by friday (extra paycheck this month) but i would REALLY like to figure this one out and fix it so i can spend that money on a new AA SYE / tom woods DS so i can ditch this t-case drop (http://www.4x4groupbuy.com/store/adv...aft-p-115.html)

I have a 3000 watt Coleman inverter I will sell to you for $175.00 shipped. I was in a Land Cruiser and only used one time to power an electric chain saw. I bought a small gas chain saw and took the inverter out. I also have a few feet of the heavy duty wire left over to get you started. Let me know.

depending on how much it costs me to fix the jeeps heater i might buy it still for other stuff, where are you located? and is there an airport by you that i could meet you at to test / pick it up? lol

You could try heated seat covers or if your handy, buy the cheap heated pads and install them in the seat your self. a warm seat goes a ways if your heat doesn't work.

I am in Chapel Hill, N.C. and the closest airport is Horris Williams, but it is private, unless you are a big whig.
Also, IIRC the inverter is 3000 with a 6000 peak output. If you are seriously interested I will check. I was thinking about selling it, with a bunch of other stuff at a yard sale we are having at the end of the month.

lol im no big wig, just an airline mechanic (who obviously doenst mess with the electronics much haha) so it tends to be cheaper to fly for me (free) than to have it shipped, im going to try and get the jeeps heater fixed and if i can get it done cheap ill let you know about the inverter, but if someone else wants to buy it sell it to them for sure
