Does this have an internal battery or does it remain plugged in constantly? If it has a battery, how long does it last?

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 internal battery. Must be plugged in. Can be hardwired or you can use the cigarette lighter plug which is provided.

It has it's own rechargeable battery included. You flick a switch on the back, unplug it and you are good to go. I used it for about thee hours this weekend at moderately high volume for three hours before the battery gave out. The battery is not removable.

No, it does not have a battery inside of it. Do consider, though, that when you plug it in, it blocks 2 outlets (the one you plugged it into and the one above or below it) giving you a net increase of 1 addtional plug (plus the usb port, of course). As a result I have never really used it.

There's an AC adapter to charge it....I haven't tried keeping it plugged and using it - but once charged it will keep for quite a long time I've noticed!

You can keep it plugged in all the time and you won't damage it. I think it takes at least 20 hours to fully charge it, after it's been totally drained of it's power.

It must remain plugged in. There is no internal rechargeable battery or batter compartment.

2.5 hours is a long time. I have to keep mine plugged in constantly. The battery is terrible on this thing. After 6 months of use its even worse.

Its a plugged in only...I dunno where you see it has a battery at? I assure you that it doesn't work like that.

It has an internal battery and you recharge via USB either plugged into computer or a wall plug. You can also use it while plugged in.

Hello Barbara,This plugs in and does need to have the switch continually held. That said I'm fairly happy with it and as I'm unlikely to know ahead of time when I need it prefer to not worry about the battery being dead.

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!

This is a very small device without serviceable batteries...no snap opens etc...it is recharged automatically via the usb cable. The batteries will last for at least one hour or longer...I let my dog run and have made videos much longer than an hour...and still have some battery left...I shut it off intentionally...never had a problem with not having battery power available...but I also make sure that it is fully charged before using...I leave it plugged into my computer before use...

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.

4-6 hours of continual use when new. My son's is several years old now and now needs to stay plugged in. It comes with a car charger and wall charger though so it's not a huge problem.
