How long with this run off of 12v? (Does it drain the battery fast?)

If u run off your car battery I would keep your eye on voltage gauge. I use it in a tractor with opti idle so I don't worry about it draining my batt.

power draw is 4 amps @ 12 volts. So if you have an 80 amp-hr battery you'll get 20 hours.

I'm actually not sure because I've never run the battery dead to worry about it. I'm very happy with this purchase. Keep in mind it is not heavy duty, but it does the job for any smaller clean up jobs. I'm a guy but I got it for my wife but I use it more then she does.

I am using this for alarm system backup (line power failure) so it sees infrequent use. Still near 12v after a year.It will probably go 3 years but I'll swap it @ 11 volts-open.

You could buy a AA battery pack that could fit 8 of them which would make it 12v but it wouldn't last very long. There are longer lasting 12v batteries out there but biggee and heavier which you still need to recharge. If you are constantly draining and recharging, you'll have to consider a deep cycle battery. So it depends on your application

It runs fine off a 12v battery. A 2.5x5.5mm plug and cord is included with the unit that plugs into the fan housing. There is no connector on the other end of the cord (all you get is bare + & - wires) but once connected the fan runs at about ~0.6 watts of power max on a 12v battery drawing ~0.05 amps. It would use less that 15 watt hours or just over 1 amp hour of power per day running 24x7. I plug it into my 12v Goal Zero Yeti power pack which charges from a solar panel and it works fine!

It can be operated off of a 12v power supply but it does not charge a battery. It does not have a permanent internal battery like many others. If battery operation is desired you just purchase them at your nearest store (size "C" I think).

Not good. It drains really quick depending on what you are doing. A full charge would last about 1 to 2 hours. However I have it plugged in all the time so it is not a problem for me.

Very well built, I like it. The output is is 12.0 volts. This is good for a jump start, but can't recharge a week battery at 12.0 will need 14+ volts to recharge a week battery.

I don't know about battery life as I've only used it with the AC adaptor. There is a sticker on the back of the unit which says: 12v = 600ma. I assume that must be the voltage and current required to power the unit. That matches the rated output of the adaptor.

I've mostly used it on USB, but from time to time it comes unplugged and I dont notice til days later that it's still running. I've never attempted to use it for 80 continuous hours, but I'd say it lives atleast 60 before it needs a charge.

if you leave it on 24 hours straight, like i did, the battery drains considerably fast haha

I'm going to assume it's a standard 120v television, so you will have to power an inverter to get the 12v DC up to 120v AC. You have some loss in that process.The basic math is battery voltage x battery Ah so 12x35=420 wh. watt hours. That will run 420 watts for 1 hour, 210 watts for 2 hours etc. In theory. But you never want to drain your batteries below a certain point. I've been warned not to discharge batteries more than 50%. Plus the loss from the inverter, lines etc. You would be looking at 6 batteries just for this simple math not even taking into account the discharge factor. If I'm wrong on any of this someone please point it out. I'm going to assume it's a standard 120v television, so you will have to power an inverter to get the 12v DC up to 120v AC.

I do not know that for a fact. However, I would assume the worst and not run it on a car battery for that long. My usage pattern only had it in the car without the engine running for at most two hours. Otherwise, it was plugged in at the hotel/motel using the conversion kit which is sold extra.

The unit is 12v DC at 1000ma. I've used it on camera batteries of different type with no problems.

No It's a 12v battery. Charge time is fast about 20 min. If I remember correctly.

I have experienced no battery drain issues. I almost always turn it off when not in use as a precautionary measure. It has been on no longer than 24 to 48 hours without cranking a vehicle. Like I said earlier , I have never had any issues. It seems to use minimal power.

i've had it running for as long as 1 1/2 hours without losing power. I never used the camera long enough to drain the battery.
