Will this discharge the battery when not plugged in?

I suppose it's possible there would be a slow draw on the battery if the status lights remain lit. I haven't actually checked that.

It worked for me NOT plugged in. Try that. It is a terrific device. Make sure it is charged, then unplug and run it from the charged battery.

Yes. It automatically turns on once plugged in, but can be shut off while charging.

Yes, but is not something you have to get out and re-charge. I guess it does it automatically, so when your power goes out it stays programmed.

Mine will run off the cord, but I plug it in before the battery is completely dead. If completely discharged, you may have to wait a few / several minutes for the battery charge to build a bit. Not sure. DO NOT let ANY rechargeable batteries charge constantly between uses. They can over heat and cause a fire. It happened to me (but it wasn't this light that caused the fire - it was a rechargeable drill).

I leave mine plugged in all the time when not in use. The battery hasn't been a problem for me.

You could leave the unit plugged in until you need it but it's not necessary. It holds a charge for a very long time. You won't be disappointed. I purchased this for my husband three years ago for Christmas. He still says this is his favorite present, EVER!

NO. I have it plugged into my computer battery back up so I can use it when the power goes out.

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.

The person I purchased this unit for, leaves it plugs in at all time. She unplug unit for several day while on vacation, and the battery died. So I suggest you leave unit plug in at all time to preserve the battery life.

This item doesn't have an internal battery. It has to be plugged in during operation.

no. however if it stays plugged in, the controller should draw power from the console.

YES... If AC power is connected it continues to charge the battery and the charging light is on. If AC is removed, it should continue to operate but once removed, with no battery, it will stop due to no power.

No, it will not. The unit will not run while plugged it until the battery is partially charged. If the battery is worn out due to age, the power adapter is useless and you will need to purchase a new battery from Wahl. I've had my unit for 4 years and have thoroughly tested it. The battery is not covered under the warranty plan as it is considered normal wear and tear.

The battery on my device is rechargeable so there is no need to plug it in to use it unless the battery is dead.
