Does this device charge up when its depleted or does it just charge other devices so many times and then its useless?

This works like a bigger battery, that can be charged over and over again. So you charge it and then you can use to charge a device/phone. With my HTC android phone on position 1 or 2, I can get 1 full charge. The 3 position are not well described, except how many milliamps (ma) are outputted.

This device can be charged by usb cord to computer or usb to powerblock outlet numerous times. I use it as my purse back up as it is smaller and lighter than other backup batteries we have. This charges my Android 4.3 phone between 40 and 50% before needing to be recharged.

You have to recharge it time after time. I haven't reached its max life yet, but of the 6 I have purchased, all have been used at least three times with no degradation (and one I have charged a couple dozen times), other than the one that charged but didn't work at all when I plugged in the phone. I get about 85% of a charge on my iPhone 5 with one charge from this device. Hope this helps. Is that what you were asking?

I do not own either, but I see no reason why any USB device couldn't be charged using this device. It works on my tablet, phone, e-cigs, and MP3 player. To charge my phone the phone has to be off (otherwise it tries to boot from the USB). That applies to the tablet, as well. If your charging cable ends in an USB it will likely charge. If you have difficulty charging, try turning it off. I've found that it will fully charge my tablet once OR charge all my other devices (2 e-cigs 1300's, phone and MP3 player) once.

You have to charge it on your computer. One charge is only good for one charge on your phone, then you have to recharge. I ordered two, one for me and one for my husband but it definitely was not worth it.

The first time it is plugged in it backs up everything. After that it should back up only new data, unless you request it to back up everything.

1.) I didn't try syncing multiple devices simultaneously but it will sync to multiple devices. 2.) It is a standard mini USB 2 connection. 3.) It does work while charging.

It says in the packet to let it charge for 5 hours or until the light turns blue. I did this and it stillwouldnt ccharge any of my devices. I actually bought another one and it works fine. Im guessing the first one was just defective. My new one ibe left on charge.over night and it seems to.work just fine.

This model sucks as far as that is concerned get the one off ebay that doubles ad a jump pack and laptop charger. But to answer your question It only charges one at a time. The two ports are a 1.5 amp and a 0.5 amp port either way I have had devices on this thing and they never filled up... they will continue running but filling one up is never really easy... also check into spare batteries for your phone on ebay... they are usually only like $5.00 so good deal...

Well, this is something everyone agrees on. When you attach your device a number of the four LEDs will light up and start blinking, depending on how discharged your device is. You are fully charged when all four are lit up and steady. It really is something I've found very handy.

It doesn't take long to charge the device. It will only fully charge your phone once or twice I'd recommend investing in a better one if your looking to use it a lot.

This is just a guess, but the device is digital. It is possibly not fully charged and so goes to the highest level it can maintain. As its power drains below what's needed for the highest level, it drops a level. If it is fully charged, it might be defective -- ours stays on for extended periods.

No I've charged it time and time again with it off. Its best that it's turned off during such process due to the fact in its on state it will be corresponding as a active device.

Do You know how many amps consumes each of your devices? Each USB port of the charger has a specific load. Surely it will charge all your devices. But you need to give me the individual amps for me to tell you if all charge together and best.

Mine did the same thing. Just leave it in. It charges just fine (even though it saus differently)

Sometimes my own does that when it is not charged adequately. I charge mine every night all night. I have had it since February I believe. Works fine. It does say if it is run completely down, you do have to charge it longer to get the strengh back. Other than that maybe it is wearing out. Bluetooth earbuds usually blow after a couple of months of steady use and are much more expensive and not nearly as effective. I would just buy another one.

I found that it charges via a male-to-male standard USB cable, and beeps when it's full. The indicator is counterintuitive - one light appears to mean full charge, and four lights low charge.

The EZO itself recharges by plugging into the wall. The EZO then plus into my devices charging port. I get three full charges before the EZO is dead.

That is a great question. I really haven't noticed it being drained too much after no use. To be honest, I haven't really tested that too much. I think mine is dead right now. I would think it's like every other battery and it will lose some charge after no use. Just don't know how much.Regardless, it's a great device and I love it. It's saved me several times.
