How long will the charge last if not used? (How often to I have to charge it even if I don't use it? I only want it for emergencies.)

The charge should hold, can't really say for sure because I use mine often. Just remember to unplug the wire when youre not using it so that the powerbot doesnt think it's charging a device.

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 keep it plugged and use it every morning so I never have it run out of charge. I think it will run O. K. if you have to plug it to finish in the event the battery runs out.

The end that charges the item has to be plugged into a USB receiver. Either a PC or an iPhone plug that plugs into the wall. To add to my last review... I must say that after re-charging it and using it a few times, it seems to be holding a charge way longer then the first time, making it more handy to have for emergencies! I'm considering purchasing another for my teenager. Hope this helps!

I do this a lot! I have never checked the time a charge last but the speaker holds a good charge. I have never run out of charge time. I use my mine all the time around the house and have one for my car.

No warning, but I have used it for over 60 hrs without recharging. Like 3 months occasionally using it for 1 to 2 hrs a time. Not sure what the norm is.

Brand new with average use it will last more than 20 hours. Do not make the mistake of overcharging the battery. Disconnect right after it is fully charged. The battery will start dying faster which happened to me.

No. You only need to charge when needed. I have only charged mine once in two years. And yes, I use it often.

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.

I think they say not to use it plugged in, but the charging time is a short four hours and the charge lasts for many hours, so the power it uses without being plugged in is more than sufficient to tackle the job.

would think it would stay charged for 5 days if turned off when not in use. But to be sure, take an extra battery.

I keep it charged all the time, but I don't know how necessary that is or how long it will hold a charge when it is not on the charger. I do know that if I took it off the charger for any amount of time it would disappear and never be seen again (hence why I keep it on the charger).

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

If it doesn't stay charged at all, then it's defective. If it stays charged, but not as long as you think it should, it could be usage. I use mine walking my dog every night. Granted it's only 20 minutes at a time, but it seems to stay charged for about 5-7 days, using it once a day for 20 minutes. When my husband uses it on a project, I have to charge it more frequently.

Not that long! If it's only working when plugged in, something is wrong. It also holds a charge for quite sometime. I can't remember the last time I charged mine (though I only use it sporadically).

Mine I've charged twice since about 8 months ago and its always pretty full. I only use in emergency as well but i can always guarantee it will at least be at the % i left it at last. Its probably loses battery about as much as your normal energizer battery not in use.

You are only suppose to recharge the battery no longer than 6hrs; however, I can charge it 6hrs and when I go to use it - one charge will last about 30-45mins....

I have only used it a few times but it has worked everytime for me. If my phone is almost dead it doesn't take it to 100% but usually to the 80's. Mine didn't come with any information on it so I've never been sure how long to charge it. But for the few bucks that it costs I think it's a decent buy.
