How long RP-PB11 hold energy between charges? I'm planning to use it may be once every few months. Should I charge it after some time of non-usage?

The self consumption of the power bank is very low and it can hold for more than half a year if you fully charge it once. However, we suggest you to give it a full recharge and discharge every two month to extended the battery life span.

Too early for me to give you a statistically accurate assessment. However, if you are going to store this battery for some time I would bring the charge down to about 40 percent charge and then store it (non usage).

It holds its power really well I've had mine sit for months and not lose any charge

I'm routinely using it for 3 to 4 hours and still has a charge. Guess I could probably go 4 1/2 to 5 hours. Definitely was a good purchase - at least for how I use my computer.

If it's first time after ur purchase than as per manul instruction may u need to charge little long but for routine use 4 to 6 hrs should be good. I usually put it in charging for mostly overnight.

After you do the initial breakin procedure, you're technically supposed to use it until it's fully drained then charge it. I like to get my cake and eat it too, so my opinion is that it sucks to do that, so I charge it whenever I want to so that I can guarantee I have a full battery to start with when I need it. I've been doing that for the last 2 years and the battery life is probably still about 80-90% of what it was when I first got it. I think it's well worth it. It's cheap, so when I feel like it's no longer able to hold a capacity that I'm happy with, scrape it and buy a new one.

never timed it, but usually i charge at about 50-25% available power and seems like it takes several hours--It just leave it in charger in the AM and remove later in afternoon..Sorry not exact..

U should charge it once per month. Never let it drained completely. We hooked ours to solar during the day. We don't charge it using AC power much

Sould but where batteries are concerned I don't like to rely on continuous charging over a long period of time. Charge, chweck state of battery and shut off for a month. Batteries in good condition don't need continuous charging.

You won't know. If you use it a lot, you probably should just count on charging it once a week.

I re-charge until the green light goes off. This is only when I know I'm going to need it soon. Obviously if it will be weeks or months before needing it, I don't re-charge.

Did everyone try charging the unit while it is powered off? It seems to make a different to me. I bought three(3) and so far all battery seemed to be decently averaged out around 2.5 hours or so (mainly net surfing and video conferencing) after few months of usage. Power on while charging seems like charges don't hold too well even it shows 100% charged. Try it out...it may make some different.

It seems to last a number of hours. I charged it initially and have had only one time where I ran low. It gets used two to three times a week and I only charge it once per week.

On a full charge Ive found that true to their word that a charge will last the full 11 hrs or more. I have not had a power failure yet.

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!

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).

I'd not assume it's safe to leave it plugged in unless you see a statement saying that it is. In fact many manuals will say "Don't charge for more than 24 hours" or "Don't overcharge" showing that you shouldn't leave it on. If your thinking of that so it has a routine "fresh charge" that you don't need to think about doing regularly I'd get a timer that turns it on for just 15 minutes a day and/or a regulated power supply (like the Schumacher PC-6 or Coleman powerchill cooler AC supply) that won't "overcharge" it.

When it is fully charged the light turn into green and stops. I don't think there's any problem in living it more hours connected... I have forgotten it some times charging of r a day or more and nothing happened...

I have only charged it once since I bought it about a month and a half ago. I use it occasionally during the day to reinforce our dogs commands and then turn it off when not needed.
