Braun Oral-B Toothbrush Chargers

Over the years various models of charger have been supplied with, and are available for, recharging Braun Oral-B electric toothbrushes. In this guide we take you through the different charger models and which toothbrushes they are compatible with, along with where to buy a replacement toothbrush charger.


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.

Type 3709 Charger

The Type 3709 Braun Oral-B charger was supplied with Vitality toothbrushes marked Type 3709 or 3737 on the bottom of the toothbrush.


Only certain toothbrushes will fit on this charger due to the proximity of the body of the charger to the peg the toothbrush stands on to charge.

Type 3731 Charger

This Braun Oral-B charger is unique in that it has the high-voltage to low-voltage conversion circuitry contained within the electrical plug and a low-voltage cable connecting it to the charging stand. The Type 3731 charger was only supplied with Triumph V1 Professional Care toothbrushes, which were marked with the Type numbers 3731, 3738 and 3745 on the bottom of the toothbrush handle.


The top picture above shows the Europlug version and the lower picture shows the UK shaver-plug version with its electrical specification printed on it. The Type 3731 charger is universal voltage (100-240V AC) and it has a velcro strap to keep the cable tidy so it can be considered a travel charger.

Type 3746/3747 Charger

Pulsonic toothbrushes from Braun Oral-B came in both the original Pulsonic (non-slim) version and the Pulsonic Slim version. These brushes were supplied with slight variations of the same Type 3746 charger which was also fitted with slightly different plastic shrouds to the top to support the toothbrush. As you can see in the photos below, they look quite different with the shrouds in place:


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.


These chargers are universal voltage (100-240V AC) so can be considered to be travel chargers suitable for taking away on trips. Make sure you buy the correct variation for your toothbrush so that it has the correct shroud fitted as the shroud must match your slim/fat Pulsonic toothbrush. The shrouds are not interchangeable.

  • Type number marked on charger: Type 3746 or Type 3747
  • Fits toothbrushes marked: Type 3716, 3716A, 3717, 3722, 3723 (depending on shroud)

The Type 4725 charger was supplied with the Plak Control Travel toothbrushes from Braun Oral-B. As you might expect from the name of the accompanying toothbrush, these chargers are universal voltage (100-240V AC) so can be considered to be travel chargers suitable for taking away on trips.

73 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.

      1. Hi, But is there a difference between the US bases /chargers and the European ones?
        The writings on the bottom of the base is different ( 100-130V in US, 220-240V in Europe). Users reported that they have used the us charges in Europe with only plug adapter and no current converter. I suspect that the bases are pretty much the same worldwide. can it be checked? does anyone knows if it is true?

  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 as detailed on our new toothbrushes page 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.

      1. Did you ever sell that 3731 charger?

      2. Can the peg be cut off a charger so I can charge my Triumph on another charger?

        1. The geometry of the induction coils is different between the 3731 charger and the other Braun chargers, so this is unlikely to work effectively. The electrical specification of the induction coils is also likely to be different.

  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

    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.

  13. Just bought a new 1500, can I use the 4729 charger. We like the storage on it.

    1. Yes as long as it physically fits and seats correctly.

  14. I’ve had a lot of oral b brushes over the last 20 years (Now I’ve found you I will try to replace the battery next time, as per your guides). I have several different chargers that will work on my family’s 3767 and 3766 brushes, but they have different wattages from 0.9W and 1.2W 3575 chargers and a 2W one that looks to say 6729 (looks like a 3709). Given the different powers of the chargers, I assume the bigger ones will charge a brush more quickly but will they harm the batteries inside?

    1. Hi Andy, the higher wattage chargers just waste more energy as heat due to their older internal design. They don’t charge the toothbrush any faster. The newer, lower wattage chargers are more efficient in their power conversion so waste less electricity while giving the same output.

  15. Looking at type 3764 toothbrush, on would think that the 3731 charger might work in addition to the type 3757. Is this a dream? (I have five of 3731 and no 3757 and need a new handle….)

    1. Hi Gena, I don’t think the 3731 charger will work with any handles except the Type 3731, 3738 or 3745 toothbrushes. These chargers are quite valuable so you could easily sell a few of them on eBay to cover the cost of a new toothbrush. New brushes come with a new charger anyway.

  16. i have a braun type 4730 which buzzes but without turning the spigot: how can i open it to check whether it needs a new battery?

    1. See our guides to opening various toothbrush models here. The type 4730 is not covered but it will probably open from the bottom.

  17. I have Oral-b i0 type 3758 and require a charger fore it, would you please tell me the name of supplier or any other charger can be used

    1. Your Oral B iO type 3758 toothbrush requires a type 3768 charger. What country are you in?

  18. I have a 3766 toothbrush which is a Li-ion Lithium battery unit and they are 3.7 volt. Is the 3757 charger which is used for the NIMh 1.2volt toothbrushes suitable for this?

    1. The type 3766 toothbrush was originally supplied with 3757 chargers so this will work for your brush. The chargers output high frequency AC and this is regulated to the correct voltage for the battery by the brush’s own charging circuitry.

  19. hello, I want to order—oral B Braun triumph toothbrush 5000 series type 3738 charger only…do you have one? I don’t mind if it is reconditioned? ty..ed guevara from the Philippines

    1. You’ll need a type 3731 charger for your type 3738 toothbrush. These are available through the eBay links in the 3731 chargers section here. Make sure it has a suitable plug to fit your wall sockets.

  20. HI

    I have a 4729 charger 2 watt output and around 5 x 3757 0.9 watt chargers. My new lithium powered toothbrush type 3766 came with a new 3757 charger.

    Should I just bin the 4729? I note you don’t mention this model/charger combo as suitable.

    Since I have very old toothbrushes and brand new ones all supplied with 3757 chargers I think maybe I should dump the 4729. Not sure where it came from or what with but the extra wattage made me think I should keep it? Thanks

    1. Hi Steve, the extra wattage on the 4729 charger relates to how much power it consumes from your mains supply, not the output. Some of this is wasted as heat during charging – more than the 3757 chargers waste. The type 4729 charger will work well with the toothbrush it came with (probably a type 4729 brush). Otherwise you can sell it along with some of your unused 3757 chargers on eBay.

      1. Thank you very helpful. I have a Panasonic irrigator charger , a 4729 & 3757 charger in the bathroom. Be good to get rid of one!

  21. Hi I am looking to buy a replacement charger for an Oral B io9 and cant seem to find it anywhere, can anyone advise where i would be able to get 1 Thanks

    1. The Oral B iO series 7, 8 and 9 toothbrushes have type number 3758 marked on their handles and are also known as iOM7, iOM8 and iOM9 brushes. These type 3758 brushes are charged using either a type 3768 charger or a type 3759 charging case.
      What country are you in?

  22. Hi,
    I have a type 4736 handle with type 4729 charger ( think it was a wall mountable one – but just used as standalone), still perfect working order. Have bought a new type 3766 toothbrush for my grandaughter with type 3757 charger. Are they all interchangeable??. Would prefer to use smaller charger for travel, but don’t want to damage new handle.

    1. In general the chargers are interchangeable but with a few exceptions. The newer 3766 brush should charge on the older 4729 charger fine. The older 4736 brush will charge on the newer 3757 charger but you might find that once it is fully charged the light on the toothbrush will start flickering. I am not sure if this is damaging to the brush or charger and it could be due to the charger wanting to shut off to save energy but it keeps reactivating because the brush is slightly incompatible.

  23. I want braun 3768 charger. How can i buy it?

    1. What country are you in?

  24. Hi I am in Singapore, where can i buy type 3768 charger for io9 please? I do not mind ordering from US or UK if not available locally

  25. Unconfirmed – the part number for io9 charger is 81739985A

    3758 Oral-B Replacement Parts – Encompass › Oral-B › Health & Wellness
    Oral-B 81739985A High Power Charger Na White.

    3758 Oral-B Replacement Parts – › model › ORB3758
    Oral-B 81739985A High Power Charger Na White.

    This looks like the standing magnetic charger for i09 – cannot be sure.

    1. Yes this looks like the internal spare part number for the Type 3768 iO series charger in white with North America/Japan plug, and 81739986A for the black one. You’ll need to verify that these will work on the voltage in your country if it’s not 110V AC.

  26. I have the Braun Oral B electric toothbrush with timer and have lost the cord. It says Type 3710. Which replacement charger should I get

    1. Type 3757 chargers are supplied with type 3710 Vitality toothbrushes, so a replacement type 3757 as shown in our article here is what you need. I’ve updated the list of compatible brushes for you to include the type 3710 brush.

  27. Hi,

    I’m looking for a charger for the braun oral-b aquacare 4 water flosser, can you help with the 4 digit identifier I’d need for that component in the UK?


    1. Hi Matty, for the Braun Oral-B Aquacare Waterflosser (Type 3720) it looks like these need a Type 3726 charger.

  28. I have an old braun wall mounted type 3719 with a 4736 type brush
    I want to buy a vitality 100. Can I charge it on my old base?>

    1. Yes you should be able to charge a new Braun Oral-B Vitality toothbrush on your type 3719 OxyJet flosser/toothbrush system

  29. Hi- I’m looking to upgrade and have seen the Oral B Genius 8000 Dual Handle Toothbrush – as this comes with one charger do you know if I could I use an old 3757 charger my current brush uses? thanks so much ..

    1. Yes I believe so. It looks like the single charger supplied with the dual handle pack is a 3757 too.

  30. I am trying to find a new replacement charger for my Oral B toothbrush type 3772. Which charger should I purchase as a replacement? Thank you!

    1. For the Type 3772 Braun Oral B toothbrush you need one of these Type 3757 chargers.

  31. Which chargers would be compatible with a Braun Oral B toothbrush which says N2820 on the bottom of it?

    1. Is there a 4-digit Type number marked on the back or bottom of your brush? N2820 is an approval certification carried by multiple different models.

  32. Hello
    I have a ORAL-B charger with number 3747
    It says 0.6W, not 1.2W

    Can I use a charger number 3746, that says 1.2W to charge my pulsonic 3717 tootbrush?
    The shroud is interchangeable.

    I ask because we have booth tootbrushes, 3717 and 3716A, and 2 chargers. and when we travel we have to take 2 of those stupid chargers with us. I could only take the shroud…and it would charge faster.

    Or is 1.2W too much for my 3717 tootbrush?
