How long does the unit stay charged? My husband works offshore and leaves his truck in a parking lot for 6-8 weeks will it still be charged?

Yes, it will still be charged. The best way to use it is to connect it to the truck battery and wait 5- 10 minutes and then try to start the truck. I have had mine for several years now and still use it every so often. It is a good jumper when you use it right and take care of it. Mine holds a charge for several months at a time before I get around to charging it again.

I don't know. I charged & put it in my truck. I haven't even looked @ it since then. I don't even know if it's holding a strong charge.

I had an a/c tech check and then charge the system. It was not precharged.Good Luck

I have not had any problems, I charged for 3 or 4 hours. I mounted mine in the upper left of my windshield with no problems

I took it on the road for 2 weeks without charging the unit and charged our cell phone's 5 times with 2 lights still available getting home. Ive since re-charged 2 weeks ago (june 23) and it still holding new charge

I have charged it several times and found it charges rapidly. I did it the first time overnight so I don't know exactly how long. Other charges were completed in 1 to 2 hours.

Weeks/months I would imagine. I haven't gauged the time to be honest, but think of it like a battery that is waiting to be used - if you don't use it, it will just stay charged for a rather long time. This is essentially a rechargeable battery.

I use mine daily, and if I forget to charge it up, it dies after about 10-12 hours of use. So for an 8 hour work shift, you should have no problems at all! When you charge it, a red indicator light goes on. Mine seems to go out, meaning it's fully charged, after about 2 hours.

I leave mine mounted in my truck. I don't leave it charging, for I'm afraid it might damage it. The good thing is, when it gets low, it flashes and warns you the battery is low. I then just simply plug it in and let it charge. It holds a charge for a good while.

You can go quite awhile once charged...I think at least a month if not more. You did remind me to check mine though since it has been awhile since I charged it! ;)I've never kept it plugged in though...only plugged in overnight to charge it up and it holds a charge for a good duration of time!

I cannot honestly say... At LEAST 2-3 days... I haven't let it go any longer than that, but there was always lots of remaining charge...

You can do whatever u want to but I would not do it if it was me because these things last a long time.I normally dont have to charge it up but once a week.im a truck driver and I talk on mines a lot but I have never charged over twice in one week.thats for normal talk time to .

I routinely charge it every week to 10 days for at least 6-8 hours. The charge level is about 25-30% when I do, so I'd estimate that it will safely last up to two weeks between charges. (The charge level appears on screen when you click on a vehicle location to get info.) BTW, when I looked into buying, I read in the reviews that it can be connected directly to the car's electrical system. No details, though.

It will depend on ambient temperature of where you park it. My car will charge in 3-4 hrs. depending on how much charge remains in the battery. I plug in at night with the cheapest rate of 9 cents per KW.

I believe it is one year. We have had it for several years and had no issues. We have had surges with park electrical posts. The unit will shut off to protect your rig. It will then automatically reset after a few minutes. The power will come back on. We purchased this because our rig was hit with a surge that took out our onboard surge protector and converter. Would never plug in our rig without it. Even tho we have an onboard surge protector.

I've left it for 3 weeks and lost about 25% of its charge. So after 2 weeks I think it loses 15% or so. It sustains a charge a lot longer than another device I have does (1 week for the other device).

Hi Norma. I never had a problem with it if I charged overnight. Its possible to get a couple of days between charges if its not on all the time like at work, etc. I work in call center so its off for 8hrs on those days. I was happy with it till I lost it. Like all most of the others. :-) Happy Halloween.
