How often do you have to charge the device itself?

It's the same as any other battery - depends on how much you use it..! It's a battery that gets its own charge from the solar panel then charges other batteries. If you do a lot of battery recharging, then you'll need to keep it topped up (ie, solar charging).

SORRY!! I reported that the device didn't work earlier.....I placed the unit in an east-facing window...AND IT WAS COMPLETELY RECHARGED AFTER THREE DAYS!!! I HADN'T USED IT IN ABOUT A YEAR.

On continuous play you should get a good 12 to 13 hours all depending on how long you charge it.

Depends on what mode you use, I always have it on the high setting and I maybe only charge it once a month. But use it everyday at work. I work grave shift security in a casino and I'm constantly using it. It's definitely worth the money

I have used it quite often. Actually I have two. Use them to charge iPad. I keep score for softball team at weekend tournaments and since we are outside all day they help me stay powered up once I have no access to a plug.

You really do not need to charge it very often. I charge mine maybe once a month. I also don't use it every day though. Maybe 3 times a week for not much longer than 2-3 hours at a time. So it really all depends on your usage of the keyboard.

Just plug the device into a USB port onto any computer (or any other device that has a USB port) or plug it into the wall of you have a wall USB to wall adapter. So yes, so long as you'll have access to a powered USB port, you'll be able to recharge it as often as you want.

I believe it charges while in use, but I rarely use it without having it plugged in.

I charged it as normal. I pretty much use it until it reaches around 20% battery life. I also keep my phone plugged in most of the time when under heavy use.

The device needs to be charged when it has exhausted its ability to charge. It can be recharged multiple times without any loss of efficiency.

yes, but very rarely. I go weeks without charging mine. charges extremely fast when it does need it, takes standard micro usb so I don't even carry extra charger just borrow phone cord for a bit

I generally charge it for about ten to fifteen minutes and work a full time job and it's never really died on me...If I get up to leave the computer I'll usually just hook it up and when I come back unplug it and I'm good to go. Never had it die on me yet.

Yes, I've had it for about a year, and never lets me down, it charges for like 8hrs, so I charge it at night, when I wake up it's full and good for some 3 days, it'll depend on his much you use it.

I use it at the gym and I charge it about every 2 weeks. I'd say their stated 4 hours in the description is a bit modest.

I don't really have to charge mine too often... I'd say between 150-200 tests between charges (I'm not exactly keeping count haha!). I probably charge it less than once a month. Similarly, I haven't really kept track of how long it takes to charge, as I usually just plug it in and leave it overnight, but I can't imagine it takes longer than a couple hours to fully charge? Maybe someone can provide some more exact answers, but hopefully this helps a bit. By the way, this thing is awesome. Highly recommended.

.Direction say to leave it on the charger all the time except for when you're using it so it will be charged whenever you need 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.
