If you’re just quickly looking for the latest and most widely compatible charger to work with your Braun Oral-B toothbrush, click or scroll down to the Type 3757 charger section below for info and where to buy it.

The input voltage of the replacement toothbrush charger you buy must match your domestic electrical system, as should the plug unless you wish to use an adapter. More on charger plug types below.

A Note on Type Numbers

All Braun Oral-B electric toothbrushes and their chargers have 4-digit type numbers marked on them. The type number of your toothbrush and the type number of your charger are independent and do not necessarily match. Confusingly, they used to match to some extent but in recent years they have diverged and are now independent of each other. This is why in the list below sometimes the charger type number matches the type number of one of the compatible toothbrushes and sometimes there is no overlap.

As you can see in the photos below, they look quite different with the shrouds in place:

Chargers-for-braun-oral-b-Pulsonic-and-Slim

But once the shrouds are removed you can see the difference is that the latching mechanism on the shroud is taller on the Slim version (right.) Also, the original Pulsonic version has a peg (left) for the Pulsonic toothbrush to sit on whereas the Pulsonic Slim version only has a slight dimple.

Also note that the Slim version is slightly taller at the back to accommodate slots for wall-mounting the charger.

30 thoughts on “Braun Oral-B Toothbrush Chargers

  1. I cannot find my charger for my (older model) Braun Oral B “Type 4712” (“Braun 908”). Those words are around the base of the instrument, which also has “CE NC-Accu” on the side. Help. I see none on this website for Type 4712.

    1. It looks like a Type 4728 charger would fit your Type 4712 toothbrush. It has a spline up the front of the peg that the toothbrush sits on.

  2. Is there a charger for multiple toothbrushes? I own 4 Vitality ones and shuffling around the brushes on the charger is annoying.

    1. The only official one I’m aware of was supplied with the old 4727 duo toothbrush set, but this went out of production years ago. Perhaps you could make a stand to fit 2 or more chargers wired together?

  3. Can one use a US-voltage (100-130V AC) on a European toothbrush, which typically charges with a 220-240V AC charger?

    I ask because I’ve just moved back to the States, and the EU charger I have doesn’t work as it is the wrong plug settings (and of course the voltage too high).

    I was considering buying a US-voltage charger (100-130V AC) but before I do so I am wondering if this would actually charge up the EU toothbrush properly, given it usually handles the 220-240V for a charge?

    I’d welcome any input you may have, thank you for your consideration of this (rather bespoke!) request 🙂

    1. Hi, you can put the same toothbrush on a 230V charger in Europe or on a 110V charger in North America and it will charge correctly. It doesn’t matter which charger the brush originally came with.

  4. Which new type brush ie 4000n, 2500 will charge on 4720 base. I like the storage just need new brush.

    1. Hi Eileen, do you mean the Type 4729 charger? All current year 2020 Oral-B toothbrushes will work with the 4729 charger. I recommend the SmartSeries 6000 or 6500 available on Amazon here if you want the extra features, or one of the Pro 2 (Pro 2000) models which are often on offer.
      Please note that it’s best to store your brush on its side with the head removed to prevent water from getting inside the handle. Also, only put the brush on charge when the battery is nearly empty. Don’t store the brush on permanent charge.

      1. Yes I did mean 4729 charger with lots of storage and small footprint. Thanks for that. 6000 and 6500 a bit pricy, are they nearest to my original brush? Just a thought do any oral b toothbrushs have adjustable power or just fixed for applications?

        1. The Pro 2 (also called Pro 2000) is most similar to your original 4729 toothbrush. It has 2 speeds and comes in different colours and they come with different types of brush head included. The 6000 and 6500 mentioned earlier have more speed settings.

  5. Thank you for this wonderful guide!

    In 2015, I purchased the Oral-B Braun Triumph 5000 electric toothbrush in the UK. (This model has now been discontinued.) I used the toothbrush regularly for a year — until mid-2016 — but then misplaced its charging stand. So, after the brush’s existing charge ran out, I couldn’t recharge it. I still retained the toothbrush handle and brushes.

    Now, I live in the US. This past Christmas, I found this old toothbrush handle at my parents’ and brought it back with me. My roommate has an Oral-B electric toothbrush (purchased in the States) and I tried “reviving” my toothbrush by charging it on his stand. It did not work (but the red light still flashes, indicating lack of charge).

    Is there anything I can do to get this toothbrush to work again? I know there are several factors against me:

    1. It’s out of warranty.
    2. It has been dormant/dead for more than 3 years now.
    3. It was purchased in the UK, so there may be some cross-compatibility issues.
    4. My toothbrush handle is “Type 3762,” while my roommate’s charging stand is “Type 3757.” I know the two are supposed to be compatible, but is their US-UK difference a problem?

    I just feel wasteful throwing this toothbrush away from an environmental POV. Any suggestions from you would be highly welcome!

    1. Hi! You should be able to revive your Type 3762 toothbrush. They are compatible with US and UK Type 3757 chargers so after 24 hours on charge you might find it runs a little. If not, you can replace the battery using our guide for the v2 Triumph toothbrushes here. Do open the handle before ordering to check for corrosion in case the old battery has leaked and damaged the PCB.

      1. You need maybe 1.2watts charger

  6. I have a triumph professional care model 3738 but I cannot find a charger for it, could you help me?

    1. Hi Jean, your Type 3738 Triumph Professional Care toothbrush is a v1 Triumph and takes a Type 3731 charger. See the 3731 charger section above for details and where to buy.

    2. I have one for sale if you are interested. None on ebay at the moment.

  7. Bought smartseries 6000 but it doesn’t sit fully on my old 4729 base. It does charge. Is it OK to use like this? It’s amazing how slow old brush had got compared to new one. Got extra £10 off the price it was at when you recommended it.

    1. You’re right that the v2 Triumph toothbrushes (types 3761, 3762, 3764) like your SmartSeries 6000 don’t quite fit fully on the 4729 charger. How annoying! However, if the toothbrush fits on far enough so that it activates the charging this should be okay. The only drawback is that it might take slightly longer to charge if the inductive coupling isn’t fully aligned.
      If it is only the plastic lump on the back of the toothbrush that stops it from fitting fully on the charger this could potential be cut or sanded slightly.

  8. Hello I have lost my Braun oral b charger.
    The number on the bottom of the tooth brush is 3754
    On side is NI MN. I can not find these advertised
    Fred

    1. Hi Fred, for your type 3754 toothbrush you need a type 3757 charger as shown here.

  9. Hi looking for charger type 3765, where can I get it? Thanks

    1. For toothbrush type 3765 you can use charger type 3757.

  10. I have existing Type 3757 charger. I am planning on buying Genius X 20900S dual pack, which ships with two handles but only with one Type 3755 charger. Will I be able to charge Genius X also with my older Type 3757 charger?

    1. Yes the Genius X brushes (marked 3765 or 3771) will charge correctly on a Type 3757 charger.

  11. Where can I get a 3731 toothbrush charger that plugs into a standard wall plug? The one I have no longer works.

    1. The type 3731 chargers are no longer produced but you should be able to find one through the eBay link in the 3731 charger section.

    2. Where can I get a 3731 toothbrush charger that plugs into a standard wall plug. Mine has worn out. I prefer not to order on eBay. Had a very bad experience with them, but so far that is the only place I have seen one. Please help.

      1. The type 3731 chargers were discontinued several years ago so they are only available second-hand. The easiest place to find them is through eBay. You can use an adaptor plug if it does not fit in your wall power outlet.

  12. This morning, upon attempting to use my Braun Oral B Plak Control Ultra electric toothbrush type 4728, which displays a tiny green light as it sits on the base of its charger tower, had melted overnight. Granted this is an earlier model, but can it still be used?

    1. Hi Brenda, if your charger has melted then it is unsafe to use. If the brush has melted at the bottom where it sits on the charger then this might have been caused by the charger overheating. You will likely need to buy a replacement charger. If in doubt get a qualified electrician or repair-person to check them for you.
