Does this have an internal battery it stores a charge in to be used later? Or will only charge directly to other devices?

No internal battery and yes you can charge directly to devices but you can buy a battery pack for under 10$ .

It only charges directly to other devices, there is no internal storage battery. I would suggest paring this product with several of Anker's portable battery packs, they work flawlessly together.

You can charge it directly from your phone, however once the battery finally dies you have to charge it for 12 uninterrupted hours. Which means your phone is off 12 hours, so the external charger is nice

No, the charger does. Re-charge internal battery on the charger. One charge lasts up to a month.

It has a cord stored underneath that plugs into device directly or I charge it by plugging into computer with USB cord provided.

Yes it have internal battery after you fully charged it. Once the 12v power are at loss, you can unplug the charger and power it up to continue it as long it is already fully charged. It will be charging while you operating it with charger while you drive.

Yes, it comes with an internal rechargeable lithium ion battery. It includes a USB power cable which you can connect to your computer's USB port or other USB charging device. Or, you can use a wall plug (output range: 5V 1A-2A). I just use the same USB wall charger adapter that came with my iPad-- I simply switch out the cables.

It has an internal battery. You can recharge it using the micro usb connector, but cannot change it (at least, there is no easy access to it).

It pulls power from the 30 pin dock you hook it up to, then stores it in its internal battery. The unit comes with a 30 pin - USB cable, (an idevice cable) that you can use to plug into a USB port and charge it that way.

The one I have came with a USB cable for charging but it stopped holding a charge after about 6 months. It still works but always needs to be plugged in to the computer which then supplies power directly. Defeats the purpose of bluetooth, but does function. Amazon says I bought this, but the description doesn't look like it - mine definitely does not take AAA batteries. There was only 1 or 2 models when I got it, now there are many, and I don't think any match what I have.

No it doesn't. Only seems to charge with a wall charger. It does hold a charge for a few hours of continuous use though.

Hi Jack,I bought this for my wife for Christmas. It is charged through USB only, which is a problem for her because she wanted to use it from her iPad. It works OK, but if the battery gets low she can't recharge it without USB.

It's charged through a micro USB connection. But once charged up, the internal battery will last for about six hours while connected to it through wi-fi.

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.

It uses a mini USB, a version that appears to be it's own proprietary type of jack, on the phone end, with a wall-wart at the other end. No external charger. The batteries are definitely 'unique.'

It does have some sort of internal battery. It is sort of wimpy. It ran on its internal power for about an hour. I ran a USB charging cable around the windshield and down to the cigar lighter power adapter so it was mostly out of sight and just leave it plugged in.

I don't know what kind of battery it has but it's a good one. You charge it with a cable with a typical micro USB end. The kind that charges most android phones and tablets. Plug it into a wall outlet or a USB port on a computer. Takes several hours to fully charge but it lasts.
