Does this have an internal battery

Yes and no. I believe there is a smaller battery that remembers the stopping point when power is disconnected but not one big enough for cordless use. I read through the owners manual and checked the players to verify. The kit comes with wall chargers and a car charger. Hope this helps.

No it does not but when you turn the car off the device goes off which is a good thing. When you turn the car back on the movie picks up where you left off in lieu of starting over. I have another device that has the internal battery and I prefer this one. The other one I also bought from Amazon at about the same price.

I really don't remember. This item was such a piece of junk I just gave it away. I do remember batteries for some reason, but they were like D sized. But don't quote me. Listen, GARBAGE is what these are. With today's technology there are many other digital options that fare much better. Steer away, you'll be sorry!

I think it has an internal rechargeable battery, charging through a USB to mini USB.

No internal batteries. A small low voltage power supply for the USB.this is a great product I owned 3 of them.

It does have an internal battery but no internal memory. It has to be used with a computer or tablet

Yes - mine came with the cord which is detachable from the unit, so you can use the internal battery for short trips.

No man, it doesn't have an internal battery sadly. By portable they just mean self contained. Its quite heavy though. Slightly awkward to lug around. Great speakers though. Definitely worth the price tag IMO. You will need a 110v power source to operate them at all times though. You can run it on a car battery with the 12v adapter. Gotta leave the vehicle running though or it'll drain it fast.

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.

No it does not. This was a terrible purchase, this battery does not last for two hours. I should have sent it back but I discarded my old one and now I am stuck!

No internal battery, but you can buy a kit to hardwire it to your cars battery instead of having it plugged into the cigarette lighter.

No it does not, but it is an excellent spare battery if you already have one
