Does the power have to be on, in order to recharge?

Power it off it charges better just like a phone if you turn it off its charges faster than keeping it on

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....turn the power off to charge. The red light will come on when you plug in the charger. When the red light disappears it is fully charged.

I really don't know. I don't plug the unit in, unless I have a handful of batteries to recharge. Then the light goes on, and I figure the batteries are all recharged when the light goes off. (Trial and error?)

It is plugged, the rechargeable battery is for back up for the programmed set-up, in case there is a power outage.

No its powered all the time. Has a surge protector too. I have two and will be getting more.

Mine did not. I happened to have recently bought a power pack to charge my phone. I use it on the light so I don't have to use the computer as my energy source.

It needs to be plugged in to a usb socket to be powered. No on/off switch thus nothing is charged.

Yes, the power source, being the power coming into your home, must be wired to the emergency light for two reasons. One, to keep the battery charged in the emergency light and two, incase of a power outage the emergency light will come automatically.

Yes if used to charge a battery and then power is drawn from the battery for the lights.

When you plug in to recharge it you can use it, so I would say yes. I use it both ways. The charge lasts a long time as it had never run out on me. Lights on the side indicate level of power left which is helpful. I love this device!

No. Once it's plugged it will turn on perfectly. Once unplugged, it will turn off and rest.

It does not retain power so yes u have to keep it plugged to a power supply in order to power anything

I have tried it both ways, but it always seemed that when I left it unplugged and needed it, there was no power. Now I leave it plugged in all the time. However, probably like other devices of this nature, it might be a good idea to let it run out occasionally and recharge.

No. It has to be manually turned on and off. It will probably run out of power and cut itself off and come back on if it were charged back up.

Not to my knowledge. We used 2 of them to power a handicap vehicle and needed recharging after every use.

No.There is a charging light as you charge. In addition, a charging indicator shows you the bettery power at any time.

No, it is wired in directly, so a source of power must be present but a cord with plug could be added.

no you have to plug it into a power source. that's the only way it will work.
