Does it have an internal battery so you can disconnect from the power source and use it wirelessly?

It is wireless but not mobile. Wireless means it can connect to your browser without a direct (Ethernet) cable. I think the issue raised is mobility. It is not a mobile unit and needs a plug. It is a "Desktop" and is far too large (27 inch) & heavy to carry. It is performing admirably as a Desktop.

no it does not have an internal batteryThe instructions make it seem like it does, but if you unplug the power you crash

It's a 27 inch screen - huge for any computer. It's not a laptop you carry around with a battery. Why would you want an internal battery on a computer this size. The data communications are wireless but not the power source. There's no need for it. This is the best computer ever - head and shoulders above anything Apple offers.

Not that I'm aware of. Didn't see anything about it in the owner's manual. it is wireless so you could take it off the wall and hide it.

Yes, their is an internal battery (not replaceable) that you charge using a standard micro usb cable and any standard usb power source, just like most other devices these days.

Yes it does. But you will get longer battery life by manually switching it off.

It does. However, there is no way to turn the unit off without taking the battery out, so it runs down fast if you don't remember to remove it.

Nope. It works without any external power source and yes it works just fine.

It has a proprietary rechargeable battery inside of it. I had to take it apart because the power switch broke and fell inside of it. Build quality was... less than to be desired but it does zap.

The internal battery is recharged through a charging stand/cord. The battery is non-removable.

No, but the battery life is great. Our baby used it until he grew out of it, and we never had to replace the battery.

no,..it uses an internal lithium ion battery. But you can buy parts and replace it if needed,..but doubtful that you would ever need to replace it, as they last a LONG time.

It comes with a power supply for the wall outlet and yes it requires batteries only if you want to use it wirelessly.

It has an internal battery that can be recharged via USB on your Mac or PC. It works very well and the data it comes back with is very comprehensive.

Yes, but I use the battery alone without the plug in power. My shop is off grid so it is nice that I don't need to plug it in.
