does it have its own built in rechargeable battery like the bose speaker?

You can also get a SLA battery and plug it into the 12v input jack on the back. A 12v 7ah should give plenty of runtime. That's really the only way to go for outdoor use, in my opinion. I've powered all my portables this way for years. D cells get expensive fast and rechargeable D's don't last long in powerful systems. (as little as 2 or 3 hours in one of mine)

This speaker has a built-in rechargeable Lithium Ion Battery built in. 2500 MaH, which lasts between 10 and 16 hours, depending on the volume that you play the music at. If using it at moderate volumes, our tests have lasted over 16 hours. If at maximum volume, it lasts about 10 hours. This speaker also has a built in power bank. You can actually use the built-in battery to charge other devices that can be plugged in using the USB port on this device. There are 2 ports- one Micro USB port that is used to charge the speaker. One full size USB port that you can use to charge another device. Obviously that will affect the battery duration- if being used to charge another device while listening to music. The speaker does come with a Micro USB cable, but it doesn't have a USB wall charger included. You can use any Micro USB phone charger or any USB charger to charge the device in only 1 to 2 hours. You can also plug the included cable into a computer's USB port. Most people already have either Micro USB or USB chargers that came with their Android or iPhone devices, so the same charger can normally be used as long as it either has a Micro USB or USB port. Please let us know if you have any other questions.

Hello Dear Buyer. Yes. It does have a rechargeable battery. As manufacturer says. 3 hour.

Yes, but I noticed that it doesn't if it has fully lost its charge. I love this speaker. My son told me to not play it so loud because it loses its charge quicker .

No, the battery must be recharged in a charger built for this style battery. It does not recharge itself.

It comes with its own rechargeable battery. Just make sure you install it properly to charge first use, and let it run right down before charging it again.

No. It has a built in battery that is charged via a USB cable that is included.

NO, the battery is built in and is rechargeable, just plug it in and charge it. I initially charged mine and have never charged it again since. I use it daily somewhere in the house, I have also used it to vacuum my car; it works great!

It does not unless you have the setting this way. However, when is had to remain lit continuous the charging rate was so slow it would not charge 100% at night. I do not recommend this item. It only works as a junior varsity speaker. I found a very good blue tooth speaker at Office Depot that is rechargeable and I use this, charge and have a speaker, and when I leave for the office I switch the charge to the speaker and both are 100%when I return home.

It has it's own built-in rechargeable battery. Not sure if it's replaceable though. The FM reception must depend on your location because mine was very good but I'm in a big city.

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, it has it's own internal battery. As far as a complimentary, back-up battery, No it does not. That would be nice, and a very good selling point.

I don't recall. It has less capacity than the original battery, though. I have to plug it in every day and I get about 8 hours of music out of it, whereas the original battery would last a couple of days before I would need to recharge it. Hope that helps!

No there is no speaker built in. It does not have "blue tooth".I wasn't aware when I bought it. There is a package with a portable included available at Amazon.
