What is the charge retention on this? Will it last for weeks to a month?

It charges one phone to full charge & another to half charge. Then you need to fully recharge the power pack.

I've let it go more than 2 weeks and it retained enough power to recharge a completely drained cell phone and appeared to still have half a charge.

My daughter uses it as often as daily. We did not buy it to see how long it would stay charged. Sorry I cannot help more.

it must give you like 24 hours of use or more cause i got mines 45 days ago and charged it once ... i have used it like 3-4 times a week

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.

Hi! The battery lasts a ridiculously ling time! I used it nightly and used it for several cycles each night, and the battery lasted well over a month on a single charge

Not good. It drains really quick depending on what you are doing. A full charge would last about 1 to 2 hours. However I have it plugged in all the time so it is not a problem for me.

Hello. Based on usage a full charge should last between a couple weeks of non-usage to a few days of extensive use. Thank you

I would not expect to see it lose charge for one or two weeks. But if you are at home, just leave it plugged in. The circuits will protect it, it will not overcharge.

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 do not know how many days it holds a charge but I have had mine fully charged and unplugged for a month now and it is still fully charged as I checked it yesterday. Hope this helps.

Well..Ive had it for probably a month and a half now. I dont use to to type long papers (usually, but i have), but i do use it daily for notes and texting and i have only charged it once since ive had it. The manufacturer says it holds a charge for 60hrs of use.

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.

Mine has stayed charged for several weeks at a time; I know for at least a month.

I haven't tried to measure how long it holds a charge, but, like the others who have responded, I know it is at least a few weeks. Also like others, the blue light on mine goes off after a little while. Do you have the switch in the off position?

I can't answer that - I have had mine and been using it for about 3 weeks - and I still haven't had to charge it...

After complete charge, it will last me about a week or more. This week, I will use it 7 days for 1 hour and 30 minutes per workout.

I am sorry but I can't give you a true answer because I plugged it in and went to bed. I can tell you it holds it charge for a couple weeks at a time and has never failed me yet.
