Since I bought the product in July 2014, I can not say the fully charge lasts for 2 years without using it. In this period of 9 months I used it several times - maybe 10 times, jumping my suzuki scooter and my frontier truck, not charging laptops, tablets etc.... - and I had to charge it only once! I think this is a relly good product! I guess the BESTEK fully charged would last for one year at least for sure, just a guess....

I think I have a problem with mine. It only shows full power for about two weeks. I'm not real happy with mine.

The instruction booklet suggests charging every three months if left dormant. We just put in our phone's calendars to make sure we have a full charge when needed.

Hi Eric, I keep this charged and stored in my computer case. The longest I've had it charged without using it was three weeks. It seemed to have kept a full charge during that time. I hope this helps.

I'm not sure what you mean. If you mean how long will it hold a charge without being used I would say quite a long time, like months. If you mean how long does it last while In use then would say I get about 8 hours out of it.

Your car has to be able to charge the battery that way so i'd check your owners manual just to be safe if you havent already. but we had a Toyota Prius and the ignition battery died so bought this and a quick jump kit. we jumped it from the cig lighter anytime the car wouldn't start. we never left it plugged in longer than to start the car. hope this helps!

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.

you can start directly to play with the charge already in the cars. Anyhow, recharging a car takes only 8 minutes, while you can play with it for 20-30 minutes

Hi, Bob. The Mity-Mite should outlast your battery(ies) because you won't be using it day in and day out (at least I hope not!). I've had my Mity-Mite for about four years and have used it to jump start a variety of vehicles, including a riding mower, Toyota Tundra V8, the regular battery on a Prius, and vehicles belonging to friends. I use it five to eight times a year, so it doesn't get much of a workout and it does the job right every time I take it out of the box, as long as it has a full charge. So, I'd say yes, you should get 4 to 6 years out of it if you take care of it, don't over charge it, and keep it inside where it's dry and doesn't go below freezing. Hi, Bob.

Should not have a problem with leaving it unplugged for a half year. Remember, it is only a battery inside. If you left your car in the garage for a half year (assuming it was a good battery to start with), do you think that you could not start your car after that half year with no draw. This is a marginal example because todays cars have electronics working 24/7, but if there was no draw, it should be fine. There is a light on the panel showing if there is marginal power and should be recharged.

To be honest, it hasn't got much use in my household over the past year. We seem to just use the car charger and stick with one battery. However, I did use it the other day when I wanted to bring a backup battery, and it worked fine. For the price, it's a lot more durable than I expected. I hope that helps!

Yep, I was hoping to see reviews on it too. ALSO, I'm wondering if you charge it up and leave it in your trunk, how long does it retain the charge. I.E., sit for a year and still be able to be used to 'jump' a car?

I've never had it take more than 3 hours from completely empty, but it depends on what you're charging it with. As for how long it holds the charge, mine has held a charge for a couple weeks and any loss in capacity was not apparent to me. It may hold it longer than that, but I have used it so frequently that it has never been left alone longer than that. Make sure you charge it fully before first use, the longer the better for that. I believe the other answer was either a defective product or not fully charged the first time, because of how fast they lose the charge and how short their charging time is.

I do not know yet because I dont use it that often. However, you should follow the manufacture's instruction as always charge the camera to full charge for the FIRST time when you open it out of the box. Do not use it right away when the battery is not in full charge for the first time; I think it is not good for your battery. And always REMEMBER to charge it when not in use and I am sure that your camera will always have plenty of power. Most often people have a habit of not charging their device after extensively and abusely usage and this habit actually KILL the battery very quick. Make it a shorter life.

The owner's manual states that leaving it on charge is not a safety concern, but it can shorten the battery life. They recommend not leaving it on charge for extended periods, 30 days, if it is not used. If you are using it regularly there should be no problem leaving it on charge.

Well, I believe that anything using power from your car battery will drain it over time but I have used this product for up to 45 min with the car off and not have a problem. I wouldn't recommend doing it for extended times though. Yes, it works without the car being on.

I have doubts on this (or similar devices) being that reliable for jump-starting any car with a fully drained battery. The battery in this is about 20% the size/weight of most car batteries, so I don't expect but that much power out of them. Most manuals for these say things like "Don't try cranking the engine over 5 seconds or the battery will be damaged". The reason for that is because it's so small a battery and you're expecting so much power from it that cranking the engine seems like creating a short circuit (which could make the battery explode if kept in that state for over a minute). Although the sales people like to put the "400 amp" labels on these to make it seem big, I doubt you can really get 100 amps for cranking an engine. I've seen a fair number of reviews on units like this saying "It didn't work for me", so feel free to look at those (sometimes the negative reviews give more info than a "Works great" one where that's all they say). Also feel free to see my review of the Peak 1 450 jump starter (and that one has a 18 amp/hour battery, this one is only 5 amp/hour). I'm not trying to make you go after a brand (several brands sell virtually the same thing like Clore, Stanley, Black & Decker and more), but realize it's limitations since it's not a full size car battery.

It can stay in your car for emergency use. They suggest charging the unit after each use. The booklet says charge every 30 days and the machine suggest charging every 60 days. I leave it in the car all the time. When I have to use it,. . I recharge after each use. I also charge between 30 and 45 days of being idle. When it has not been used, it charges real fast.

Yes, you can keep it in your trunk. I would check it once in a while just to be sure it hasn't lost charge. Works great for me........ Good luck.......
