It is rechargeable. The charge lasts more than 2 weeks for me using it twice or three times daily. It is great for travel.

It runs only with an electric rechargeable built in battery that cannot be replaced. It runs at 110 volts and the charging is wireless on a mini stand via induction system so as can be charged in wet environment. I hope that this information will help you. Personal i would recommend you the other model that uses two AA batteries. Alkalines not necesary rechargeable. It lasts for a very long time the alkaline ones too.

Mine was an electric charge-comes with stand to plug in, not a changeable battery. Lasted a long time so far, although I only use the electric once a day, and recharge every week and half.

It has a base charger which you plug into an electrical outlet. After using the brush you replace it on thecharger until you use it again. The toothbrush handle is left on the charger after every use.

I believe it is AAA. I got mine for my sister and I believe that it comes with a battery.

It runs on a rechargeable battery. All I do is plug it in a few days, unplug, and it works for a long time. You can tell when your using it when it will need to be plugged in again. I am very happy with the product and because of the multiple brush heads it comes with I can share it with my daughters and not have to have several different electric tooth brushes. Hope this helps.

The device uses AAA size regular alkaline disposable batteries and consumes very low power (they last long time depending the frequency of usage), it does not make a sense to use rechargeable batteries.

The Sonicare are a re-chargeable toothbrush. A full charge last about 1 week assuming 3 brushings a day. This kit" comes with 2 handles and TWO chargers - they are small enough to pack any time your are travelling for an extended amount of time. It's always a good thing to take along a battery operated bac-up toothbrush; but I take my Sonicare everywhere. Have not tried outside of the U.S.

No, it runs on a AAA battery. And don't bother asking Coby at their support email address. They never reply to questions!

It was a gift for my son and I haven't used it. He is very happy with it and reviews on Amazon and other places were very positive. It uses two AAA batteries based on the owners manual I downloaded. NOTE: the manual says NOT TO USE rechargeable batteries.

It is an electric toothbrush that operates on a battery (rechargeable battery). It is not plugged in while you are using it.

Yes it is. Some also have a place for a (AAA) battery which will power the unit if you are away from an electric outlet to recharge it with. In other words, the (AAA) battery provides power until such time you plug in to recharge.

No. I tried to use it on my Oral B with no luck. This toothbrush has officially died and I am stuck with brushes. This was a horrible product.

The cup/glass plugs into an outlet, and the toothbrush just charges inductively - just drop it in the glass. Kind of weird having new technology emulating old school, but it works well.

It is plug in. No battery. See cordless waterpik if you want battery operated. Waterpik Waterflosser Cordless PLUS

Looks like its dual voltage http://www.usa.philips.com/c/electric-toothbrushes/for-kids-2-modes-2-brush-heads-hx6311_02/prd/en/;jsessionid=F9159B89A66591E7BD94CE761CE4B72F.app101-drp2?t=specifications

Yes it is a manual brush, not motorized. The battery helps to create the ionic charge (Sakuma et al., 1987). In the middle of the plastic handle there is a metal conductor rod. It connects the bristle portion to the battery. A second conductor (the metal strip) is also connected to the battery. When you grasp the handle of the toothbrush, and hence the metal strip, an electric circuit is formed through your body, your teeth, and the conductive rod. The resulting ionic action weakens the electrostatic bonds that enable tartar to stick to your teeth. There are ionic toothbrushes without the battery that are powered by a reversed current circuitry but Ansai et al. (2000) concluded that the lithium powered ones were more effective.

The battery lasts a good two weeks no matter how you handle it. I would not worry about it one way or the other. This electric toothbrush is a great product at an ideal price.

I have the same question and was wondering if the toothbrush supported 220V. did you find out?
