Does this have an internal battery or does it always have to be plugged into AC? Thanks.

Hi. This unit does not run on batteries. It's AC power only. The sound is OUTSTANDING for the price and size. I have had mine for a couple of months and have zero regrets.

I'm not sure I understand the question. The heater does not have an internal battery. It is powered by the golf cart batteries. We do not use our cart on on golf course. Ours is used to "tour" our neighborhood. We routinely run about 30 minutes a day. With a full charge on our batteries and running the heater for the entire time, our batteries end up around 3/4 of a full charge.

Battery is internal you plug the whole thing into the wall... It has the regular outlet plug like a lamp.

It is charged with a cord supplied via 12v outlet.Has an internal rechargeable battery buildt in. In the standby mode, I have left it on for 3 days and it worked. Great item, best I have ever had! You will not regret it I promise you!

It has no internal battery, It just allows you to charge multiple devices (not only the ones listed) from a single plug.

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

It's battery or ac powered. Mine only was used about 6 times before it broke.

My husband said it does have an internal battery but it probably won't save for more than a few minutes. Hope that was helpful.

Does this run on battery or AC power? And, if AC power, does the cord disconnect directly from the unit?

It has an internal battery that needs to be charged, it does hold a charge for over 6 hours, I have had mine run for 10 hours on a single charge.

Hey Ken. This unit has an internal rechargeable battery. Its actually pretty long lasting too (from my experience).

It is to be plugged in - comes with cord - but has battery back up if electricity should go out. I don't remember how long battery back-up last. This is a great unit and would recommend to anyone. I purchased for my mother. There is no question - she knows when to take her medication. And medications are secure. it is easy to set up and/or change frequencies if needed.

Does not have to be plugged in all the time. Just after using it and every 30 days. I don't know how much current it uses but you can keep it plugged in and it'll stop charging it once it's fully charged

It has a built-in rechargeable battery. The battery plugs in via a micro-USB charger (included).

It needs to be plugged into the wall socket at all times. No battery operated function.

This unit has no batteries. It is only powered by an AC adapter that must be plugged in to a wall outlet.
