Will it operate while the USB charging cord is connected, but without any battery installed?

Yes it will operate with the USB cord connected. The battery is built into the device and can't be removed.

It has a rechargeable internal battery. How are you planning to take the battery out?

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.

Yes. It works right away with zero charge as long as it is plugged in. This actually happened for me yesterday, so I can say without question that yes, it will.

It will work without battery. Not sure you should remove the battery. But it will work in both scenarios.

No, must be plugged in to operate....there is a "back-up"battery for the clock/alarm only.

Hi.The controller can be turned on without having it plugged in the USB cable. The rechargeable battery allows independent operation. Regards

The short answer is yes. The unit has an on/off switch. The USB cable will charge it while off and charge/power it when on.

I would say not necessary, it's your choice. It stays charged even when its not in use.

No, it powers up on it's own when connected to the USB cable that is provided with the package.

No. It has a built in battery that is charged via a USB cable that is included.

Nope, unfortunately, you can't just plug it in and run off the cord alone. It has to sit there and charge first or else it'll only be on for a few seconds before dying again, which is a significant design flaw.

Yes it can be used without the dock, and the charger should plug into the wand. It is just like any other rechargeable device in that it will eventually go down. If you are low on battery without the dock just turn it off to minimize drain.

No. This will not anywhere near charge while the laptop is active. It'll be best to charge the laptop while it's completely off. It'll take abit to charge compared to it's required amp's from it's wallplug system. But it will charge while it's off.

it won't charge it without a battery, but you can keep it plugged in and use the controller without batteries it just has to remain plugged in the whole time.
