Can you use it while plugged in without the battery in it?

Yes. Just got mine today -- it plays with the battery removed if the usb is connected to power.

I just got mine (Nov 2014) and tried to leave the battery out (to possibly save the battery from being overcharged) - i was disappointed there is an annoying buzz once the music kicks in - it's like the charging circuit wasn't meant to operate without a battery in place :(

Yes, you can. Just dry it with a towel and let it get completely dry before plugging it back in.

It does not need to be unplugged to play and can be used while charging but as in all rechargeable battery devices if you never use the batteries, keeping the unit charging all the time, you will ruin the the batteries in time and they won't hold a charge.

It is not recommended to run it while plugged in. Like most rechargeable products, it it intended to run from only the battery. Properly charge up the battery before use, let it discharge and then recharge.

Yes you can use it when the battery runs down. Under those conditions, I have just plugged in the cord and it runs fine.

No, it can only be plugged into a power port or an adapter to run directly off the battery.

yes. I use it cordless unless it runs out of battery, when I plug it in, and it works while charging.

Yes, you can leave it plugged in and ready for use. However, I found that you do not need to worry about it discharging without it plugged in and just siting there unused. It is amazing that once charged, it holds that charge for a long time. This is a fantastic product. It is better than any others that I have owned previously.

No, you have to plug it in the charge it, but then you unplug it when you use it.

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!

Yes, it can be plugged in directly without removing the battery. It has 2 ports, mini-USB and hdmi.

Sure you can. But you will not need to keep it plugged in. It should do the job without a recharge.

You can plug it in and/or use batteries. Battery life is quick with much use, so we keep ours plugged in.

Yes. I've used it while it is plugged in.When you says "use it uncharged", I assume you mean use it when the battery has been drawn to a very low level. If you plug it in, it will start charging the battery and when you turn it on, it will stop charging while allowing you to shave and when you turn it off (while it is still plug in), it will resume charging the battery. Hope it helps.

Sorry I can't answer that question. I always have it plugged in and do not rely on batteries.

My experience is that the battery has to have some charge. You cannot plug it in and use it if the battery is completely drained. Even when charging (plugged in) it will only last for a short while before the battery is too weak. So, I suppose the short answer is "no". This is a great trimmer and the best I've ever used.
