USB-A Charger for Oral-B iO Series 2-6

The Mdforme USB-A Charger 3757 replaces the original Braun Oral-B 3757 power adapter. It supports a wide range of Oral-B electric toothbrushes including Pro, Vitality, Smart, Genius and iO Series 2, 3, 4, 5 and 6 models. The USB-A input allows connection to any standard USB power source such as a laptop, power bank or wall adapter. It is not compatible with iO7, iO8 or iO9 handles.

IP67 Waterproof Base with Inductive Charging

The charger base is rated IP67 for full waterproof protection and is made from insulated ABS material for safe use in wet bathroom environments. Inductive charging begins automatically when the toothbrush is placed on the base and stops immediately when lifted. Multi-protection safeguards cover electric leakage, over-current, over-voltage, over-heating and over-load during every charging session.

Travel-Ready Design with Two-Week Battery Life

Compact and lightweight, the charger fits easily into a travel bag without occupying much space. A full charge takes around 10 to 15 hours and delivers more than two weeks of regular brushing between charges. The USB-A cable connects to common USB ports, so no proprietary power brick is required on trips.

Questions about this item

How do I connect the USB-A charger to power and what mistake should I avoid?

Plug the USB-A connector into any 5 V USB port or adapter, then set the toothbrush on the base; the charger starts automatically when the brush is seated and stops when lifted, so do not leave it plugged in without the brush if you want zero standby draw.

Will the IP67-rated base need any seal maintenance or replacement over time?

The base is moulded from insulated ABS with a permanent IP67 seal; no user-serviceable gaskets or replaceable parts exist, so normal wiping with water is the only upkeep required.

What limits how long the charger can stay plugged in during a multi-week trip?

The charger draws power only while the toothbrush sits on it — about 10 to 15 hours for a full charge that then lasts two-plus weeks — so the practical limit is the USB host’s own uptime, not the charger itself.
