How's the battery life? Can you use an AC adapter?

Great! Has worked for over 3 years now. The pen has had to be replaced several occasions though.

There is no AC adapter. It's battery operated by D batteries. I only activate it when I'm going to be away for one night or more (about once a week) but I'm still on the original battery for 6 months now.

It's battery operated, however, you can also use an AC adapter, but that's not included.

You recharge it by USB. I don't know if there is a USB to AC adapter for this item.

It has a rechargeable battery as well as the standard AC adapter. Side note: You *may* need to purchase a USB printer cable if you have Windows 8... installation for that OS is tricky. :-P

It doesn't come with AC adapter. It requires (4 )AAA batteries (included) .thank you.

I have the new version which uses 6 AA batteries. I now change batteries every week so they go pretty fast. There is built-in no port for an adapter but you can use rechargeable batteries. Or get someone to create an attachment for the adapter

Mine came with the AC adapter. It comes with it. It uses also, six C batteries,a option, instead of the adapter, get some if it might not have the adapter.

Yes, works with AC adaptor only. I don't even put batteries in unless I'm going to be using it where AC isn't available.

Hello, the AC-DC switch power adapter is good for quickly charge as table light e.g. or use as outdoor/indoor motion/sensor light with battery back-up feature instead of solar panel, and can't be replaced battery. Thanks,

The batteries are C-Cell and with average use (20-30 minutes a day) they will generally last about 2-4 weeks. However, in addition to the batteries, the unit does come with an AC Adapter. Let us know if you have any additional questions :)

Hello.There is no AC adaptor. The device requires 2 AA batts. It has brought me huge peace of mind. I highly recommend this.Getting Mom to use it, is a whole other issue. :) Good Luck!

It's already calibrated by the manufacture. You can verify. It does not need an AC adapter. It only uses AA batteries which comes in the box.

If you can take the battery out and run your laptop on just the power adapter - the battery is dead.My battery only lasted 5-6 months. Initially I got 3 hours on a charge - no more.

The batteries are necessary to keep the memory of data and setting. Other user find out that using the battery alone without AC adapter drain the battery quite fast, therefore I recommand use the AC adapter whenever possible to save battery cost.

Yes -- most of my use is AC. Battery performance is marginal when played loud.
