How long will it preserve the charge without being used?

It preserves the charge for a while. Have not used it for over a month and then charge the phone and it worked great.

Good morning-I use mine for school for charge it on a weekly basis (every Sunday) but I haven't noticed a huge decrease in charge over a week even if I don't use it during the week (10-15%).Hope this helps.

I have not had the chance to use mine as yet but I can say that the original one holds a charge a long time. If they are equal I would guess at least 3 days. ?????????don

I havent tried to be honest. The longest so far is couple of days, but i havent lost anything out of it so far. I think if u keep it for a month u might lose just a bar of its light indicator which could account for 2 to 5% of its overall due to its internal connections lost. Which is nornal for these kind of devices. But i normally keep it on the charge when i am not using it at home.

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).

it depends on the amount of usage. i use mine quite often and it has lasted for about 14 months (single cell). i use it outdoors so i would leave it directly in the sun as much as i can, that way it maintains a charge, otherwise i charge it via a 12v adapter once or twice a week.

it lasts as long as you dont use it. the battery does not lose its charge once it is charged

I'm not quite sue--I've never used it long enough to drain a charge. My guess would be several hours. Sorry I can't be more helpful.

I use it for my cell and tablet and it stays charged for about 3 days to a week depending on use. As for keeping it plugged in, i would for safety just charge it and turn it off. If its not in use, it turns off to not burn the battery out. It is well worth the money. Mine has paid for itself more then once

to date I've had it sit for 3 weeks before having to use it. I'd guess that after 3 weeks it still had about 90% of its charge.

I usually charge overnight and the charge will last for 3 or 4 hours, although I am guessing - I haven't really timed it.

As with any electronic device, it will lose some charge if not charged in between. With this particular back up, it's negligible. I wouldn't let it go a month without charging though, but I'm also slightly neurotic about making sure my charger is powered.

We purchased this for our mother to use in a nursing home. She used it everyday for six months before passing. We only charged it twice. I was surprised how long the charge held.Hope this helps

I had it running fairly constantly with my portable Passport for about 4 hrs and it used about 3/4 of the charge...so between 5-6 hrs would be my guess.

I leave mine on charge for days most times. No problem yet. But I'm sure it's good to let it run down sometimes

You can charge it 1 time and it will never lose energy i think cause i had it charged for like 3 days and i didnt use it and when i used it it charged it all up

I have used it for 6 hours, and it still had a charge. Don't know average, I charge it after use.

You should be able to hold the storage battery power that is not used in one sitting for at least a week. I have not used it after an on the go quick cell charge and then didn't use it again for as mentioned above.. A week and I still had the same charge it had when I turned it off. I think that heat and extreme cases of cold conditions definitely play a role. Obviously try to keep it at room temperature and not leave it plugged in past the fully charged Mark. This will extend the life of this great product. I have had it for a good 8months. And not a single complaint!
