Will this battery provide output (voltage/current) while itself is being charged ?

Hi Thomas, thank you for your question. For safety concern, simultaneous input/output charging has been disabled. Since the Jupiter787 carries such a high capacity battery, concurrent charging may cause current under/over-flow (output greater than input when Jupiter787 is not recharging from wall outlet) and may deplete/damage the battery. You will not likely need this feature because our Jupiter787 will provide enough power for your phone for up to 3 days.

I don't think so. It has 2 USB connectors, one is 1 amp and the other is 2.5 amps. It can only charge with the 2.5 amp connector unless you want to wait forever, so I think the answer is "no."

It will charge the internal battery. If you hook it up when the internal battery is fully charged, it will keep it that way. However, with mine, it failed after the 4 recharge and was totally worthless. I tried to contact the company and they never answered. Amazon couldn't could not, or would not do anything to help me. I would advise that you forget it unless 4 or so charges is worth the price it costs.

No. you have a built in charger in your unit and it will top charge the battery in case it is a little bit discharged.

I advise u not to charge it with a different charger b'couse it may cause defect on it . The battery can support a certain A or volts but it was designed to measure when it's full charged or empty , what i'm trying to say it's u can short the batery life if u use the wrong charger .

No....it charges only when led is alight and concludes whern led turns green. That excludes led alight while unit is in play.

Yes, when I charge the battery the light shows a full charge, but the battery is still dead.

No, it will remember. Mine actually knew what battery type I was charging once I hooked up the batteries (2 - 12v).

Yes. It charges the battery, one at a time. Very easy to use, two lights - charging and full.

Apparently it does. I just turned the power off and placed it on the charger pad. After a couple seconds an image of the battery state displayed.

sir, i am confused by your statement. i would verify the battery is being charged. since it is DC current a simple multimeter will provide this information.i purchased this battery for a back up security system. the system becomes active in the event of a power loss.

No...the external battery can not be charged as it is charging. I have tested this as well several times as I thought you would be able to.

No, the USB charges the battery and it won't work w/o battery. Although you can work with it while charging, but it is recommended not to do so, to increase the life of your battery.

According to the manufacturer, no because the power output level should not affect the battery. However, the dead panel ended up draining my battery.

Yes, the camera functions normally while plugged in. I'm pretty sure it actually charges the battery even while recording.

Yes from my experience it can. I always wait for my batteries to die completely before I charge.

No. When it's time to recharge, you won't have any power left to turn it on. Just plug it in and it will automatically recharge. A little light comes on to show you it's charging.

no, but it does bring it up to full charge. It supposedly stops the oxidation of cells, which is better for them. There is no where on the outside showing the monitoring of temperature. It will tell you the condition of the battery, once charged it will go on to maintanance when fully charged.
