How long does the power tank retain a charge once it is fully charged?

As far as sitting around, I don't think the battery leaks much power while not in use. While in use, the power tank definitely will last longer when charging something such as an iPhone because the battery is smaller compared to an iPad, which would probably take a larger toll on the power tank.

The description states it has lithium technology which will last many many months if it is fully charged and not being used. I'm very happy with mine and it has plenty of power to recharge phones and tablets without having to recharge the unit itself. I hope this helps.

Well, I once rode a plane from Boston to California with my phone connected the whole time, and it didn't die. I've never used it long enough to answer your question, but charging an iphone playing high powered apps for that long is pretty impressive.

about thirty minutes, but it only holds a charge for thirty minutes because of its size. plan on leaving it plugged in if your power card will stay in the unit. mine needs a rubber band to hold the power card in. suggestion keep looking.

About an hour or so. When it is done, the light goes from red to green but not sure if it continues charging. I have left it overnight charging and it works fine. It's a really good deal compared to purchasing a manufacturers battery. Does the same thing and last as long. Would recommend to anyone.

There is a light on the charger that changes color when the battery is fully charged. Usually, if the battery was totally discharged it will take one to two hours to fully charge.

Mine had a partial charge so I can't be sure, but I think about 4 hrs to fully charge.

It would probably stay on the shelf forever, however; drain it to 40% before first use, recharging to 100%, then draining to 20%, etc. When fully charged now I have 6 hours of time, although I haven't tested that to the max......about 4 hours is the most I have used it. I do leave it plugged in when not in use, but plan to use it on a 2-week trip soon, so will find out how it holds up when unplugged.

No idea, fully charged I can use for 5 hrs or so before plugging in, hope that helps

I found the charging time to be about a 1.5 to 2 hours. There is a red/orange light that illuminates when you first plug it in. It will go out when it is fully charged.

If the Leaf computer estimates a low range such as 15km remaining then it takes about 4 to 5 hours to bring it back to 100% charge. We charge at night when the electricity is cheaper. We often charge to 80% since this will extend the life of the battery. Good luck and consider the AeroVironment EV charger for purchase...it is a very good unit! Cheers Bill

I tend to keep mine on power save, it seems to last pretty well. I'm not sure and exact answer on a number but several hours.

Full charge in about an hour or at the most, 90 minutes. Charge lasts about 3 or 4 days.

probably a couple of hours if substantially discharged. The batteries I'm charging are not totally discharged - I just top them off every couple of weeks to keep them fully charged and it takes 15 - 30 min.

A brand new battery can take up to 3 hours to fully charge. After the battery has been charged and depleted to under 5% about ten times, the charge that is held takes about 2 - 2.5 hours to fully charge.

A few hours. A red light should come on when you plug it in to indicate it's charging and will go off when it's fully charged.

How long did it take you to charge this up to full capacity upon receiving?

It takes about 30 minutes to charge. It will usually stay charges for around four hours.
