What with the forecast for a severe winter I would really like to see this thread grow with some good information about precautions and remedies in case of power failure. I cannot afford to spend 1500 dollars on a Honda 2000i I cant even afford the 1000W model for 800. A few years ago when we had the power outage I bought one of those things you plug into your car cigarette lighter and then plug an AC device into it, my thought was to power a space heater, but it kept blowing the Durango's fuses. Herfishy mentions a power inverter and 12V deep cell car battery. I do not have a working knowledge of electricity so pardon my noobish questions. Am i right in assuming that a 200 Watt Ebo Jagger heater draws 200 Watts and a MaxiJet900 draws 8.5 Watts which compared to the heater is negligible, so it seems the real emergency power requirement is the heater. Given that the house may get cold in a power outage, I would probably be running 2 200 Watt heaters. So where is the electrical formula to tell me how long a 12volt DC battery will supply 120V AC at a 400 watt draw? Do i have to figure out amps and current and stuff?
So I am looking at the Voltec 1000 Watt Power Inverter for 80 dollars. How do i figutre out how long this device attached to a fully charged 12V car battery will run 400 Watts worth of heaters?
The following was taken from Voltecs site.
Most vehicle batteries are designed to provide short period of very high
current for starting the engine. They are not designed for a constant “deep
discharge”. Constantly operating the unit from a vehicle battery until the low
voltage shut off will affect the life of the battery. If you are operating electrical products for extended periods of time, you should consider connecting the unit to a separate deep discharge battery. OK so I guessing this means a Deep Discharge Marine Type battery? It still doesnt look good, by the estimates I have come up with 400 Watts of heaters are going to run a 12VDC battery down in less than 6 hours, probably sooner.
Any "cost effective" suggestions would be appreciated. I found this 1000 Watt Generator online for only 129.00 but it scares me because it is so much cheaper than other 1000W units. Anyone have any experience with this or any opinions?
