How much power does it draw? i.e., How many days/weeks can you go without driving the car and still have enough power left to start the car?

http://www.pocketfinder.com/gps-locator/gps-vehicle-tracker/ How does it work section: "The motion sensor also knows when your vehicle is not moving and it reduces power draw to only 4 milliamps. This protects your car's battery. The device has a backup battery that will power the device when the car is not on and notify you when full time power has been used up." I had it on a car that wasn't driven for a few weeks and didn't have any issues. I also haven't seen the battery percentage drop bellow 100% after the initial charge. It's a really great device, no complaints.

It draws almost no power while it's sitting still. After 30 minutes of no movement, it goes into "sleep" mode drawing only enough energy to wake up when the care is moved. Our vehicle has only sat for about a week but there was no noticeable effect on the starting power of the battery.

Www.pocketfinder.com says it only draws 4 milliamperes when not in use. The device has motion sensors which help it know when to use more power. If your battery is in good condition I don't see this effecting it much. I have had mine installed about 1 month

It draws a lot of juice. I had to add a bigger alternator and an additional battery. I would suggest asking the manufacturerer this question.

It plugs into the cigarette lighter in my car. I am not sure how long it will run when not plugged in. I haven't tried it. I seem to remember it said maybe 3 hours. I could be wrong.

while operating - at least 6 hours. I think mine died during the 7-8 hours after a full charge. I leave it in my car and the batteries remain charged until I actually use it and I'd say it keeps its charge for awhile, on a monthly basis. Not too sure about annually.

When your take your keys out of the ignition... it turns off the ability to draw power from your car battery. You wouldn't have a problem with this.

You can leave it plugged in but be aware that due to the budget construction it has minimal protective circuitry and could have a short lifespan running constantly, and that many vehicles have powered OBD ports when not running so it will gradually drain your battery. Estimates for current vary but are generally between 50mA and 100mA which isn't a lot but is enough I wouldn't leave it plugged in for more than a few days without running the vehicle to keep the battery charge level acceptable.

I don't know the exact number, my car has a drain of about 5 MA, I guess this thing might have only couple of MA. cause I left it on the car couple of days, I can still start my car, because, when I left it on, it feels cold than means not much drain:)

In my experience, it does not lose power when not used for weeks. I do not know how much longer it will hold a charge.

About 30 seconds after you unplug it from vehicle power source. It must stay connected to power to operate. Not a problem for me as my vehicle allows the power outlet to stay powered without key in place.

I've never had to use it until it's drained of power . I usually plug it into my car connections n it's always ready. I can say from one light indicator to full lights plugged in the wall took about 5-8 minutes. My daughter has one n she uses it all day about 5 hours at least.. it's a great buy.

Not unless you want to. It runs off the car battery as supplied through the cigarette lighter (accessory power outlet). Depending on he vehicle, you may have to have the ignition key turned to the on position to have access to battery power, but you don't necessarily have to have the engine running. I would only run the engine if your battery power is low or if you're going to spend forever inflating multiple items.

I only use it in my car. I drive about 30min to/from work 5 days a week, but the end of the week it has about 20% battery left (or less). I stop my player from my phone when I leave the car so the adapter stays on until it automatically powers itself off. Not sure if it helps, I haven't really counted the hours, but I'm pretty happy with it.

Hooked it up to the car. Used between 5.5 and 6 amps. With the car on it went up to 7 amps. I have an "average" car battery and alternator. Other setups will cause different amps. At 7 amps you may note that it is about 75 watts.

I just went through the manual and it doesn't mention power draw. However, the unit has an internal battery that supplies power until it runs low and then draws power from your vehicle to charge. There is a small blue/red light that displays what it is doing. During the set-up you can program the unit to shut off automatically after some period when you stop or leave the vehicle. It will automatically turn back on when you next start the vehicle. Plus, the on off button is readily accessible. This unit is so small I can't imagine it running a car battery down even if left on for a lengthy period (not programmed to auto turn off).

Starts as soon as power supplied. You have to be careful not to leave it plugged in all the time or it could drain your battery. I leave mine plugged in every where I go and unplug it at night. Some cars like mine give you the option of continuous power when the car is shut off or a separate plug to shut it down, when car turns off.

It can run attached to a power source but only with battery in. Thus you slowly destroy the battery's capacity to hold a charge. If you can remember to turn it off when not using, then battery will last. Don't buy it if you have a choice. I have three so far -- they only keep working about 6 months.

If the car's power port is on when the car is off, sure it'll work. Its fine to use it for a couple of hours while the car is off (depending on the health of the battery), but I wouldn't use it for more than 3 or so hours without starting the car.
