How does this work? Do you have to have this plugged in all night, or for a limited amount of time?

It depends on the temperature. If your car is outside and the temp is below freezing you could keep it plugged in but you dont want it plugged in unless the air temperature calls for it. My useage is less extreme. I'm usually parked in a garage and the temperature "usually" stays above about 40 degrees in an average winter. So, in an average winter I would probably not plug it in at all. Last year was very cold; there were several weeks where the temperature was closer to 25 degrees in the garage and several times I couldn't park in the garage and the car was outside at about -10 degrees. Those kind of temperatures can really wonk-out a car battery. I had some starting problems and decided to get this heater ready for this year. This heat strap is kinda an insurance policy for out of the average temperatures that may occur this year. Guess what, I'm already using it. The temperature is 20 degrees below average today, 5 degrees F this morning and my car is sitting in the driveway because of a project in the garage.

I just wired the battery heaters to my block heater and plug it in for however long I'm home. There isn't a maximun or minimal amount of time.

A couple hours works for me, I run it with a programmable timer. I use the same timer for the block heater.

I leave mine plugged in all the time until needed, then plug it in again. Doesn't seem to effect battery life as I've been doing this for over a year and I still get up to 6 hours of light.

I had experience with this. We had it go all night on a full charge, other times it quit around 4 am.

The person I purchased this unit for, leaves it plugs in at all time. She unplug unit for several day while on vacation, and the battery died. So I suggest you leave unit plug in at all time to preserve the battery life.

You need to charge the battery...keep it plugged into your computer over night for the initial charge

Hello. You can certainly leave it on all night. I do all the time. Also electricity is much cheaper in the later hours. :-)

It plugs in and can be set to go on and off at any amount of time you want. It works like a timer. Your in charge We just leave ours on year round and as it gets dark earlier we just change the time it goes on. I hope I answered your questions. If not feel free to ask more.

Plugged into an outlet it will charge a few hours (2-3) hours. Plugged into the computer it's much slower to charge, expect it to take all night.

I'm not sure. I purchased it for my mom awhile back. She always plugs it in sometime after coming home from work and she doesn't bother with it until she wakes up for work the next morning. I am sure it doesn't take all night, but then again, we really haven't tested it.

it plugs in, and recharges. I put them in 4 rooms and don't use unless power goes out.

It works well for an hour or two when it is not plugged in. It will keep working throughout the night with good batteries. The flow is less consistant and it gets worse as time goes on. It works best plugged in.

I tend to plug it in over night, but should fully charge in three to four hours.

As far as I know, it only works while plugged in. At least that's how mine works.

I usually have it plugged in all the time. So I really don't know how long it last or how long it takes to charge.

Hi. I think the light stays on as long as it is plugged in. I don't think it goes out when the device if fully charged, but I could be wrong. To be honest, I never paid attention. It is fairly bright, though. You wouldn't want to charge overnight in a bedroom. I usually plug mine in in the kitchen. Good luck!

I do not have this system but if it only turns on and off by plugging in and out and you only want it on at night, plug it into a timer. That might do the trick for you.
