Braun Oral-B Toothbrush Chargers

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