Electric toothbrushes, shavers, and beauty devices are among the most commonly packed personal care items for international travel โ and also the ones people worry about most unnecessarily. The good news: the vast majority of these devices already work worldwide. The bad news: the few that don't can be easily overlooked.
This guide covers every major brand and device type, tells you exactly what to check on the label, and explains the rare cases where you actually need a converter. If you are unsure how to read a power label, start with our power label reading guide.
Electric Toothbrushes: Brand-by-Brand
Electric toothbrushes are the easiest category. Nearly every model from every major brand uses a dual-voltage inductive charging base or USB charger.
| Brand / Model | Charger INPUT | Charger Type | Verdict |
|---|---|---|---|
| Oral-B iO Series (9, 10) | 100โ240V ~ 50โ60Hz | Magnetic charging stand | Adapter only |
| Oral-B Pro / Vitality series | 100โ240V ~ 50โ60Hz | Inductive charging base | Adapter only |
| Philips Sonicare DiamondClean | 100โ240V ~ 50โ60Hz | USB charging travel case or glass charger | Adapter only |
| Philips Sonicare ProtectiveClean | 100โ240V ~ 50โ60Hz | Inductive charging base | Adapter only |
| Waterpik Sonic-Fusion | 100โ240V ~ 50โ60Hz | Inductive base | Adapter only |
| Quip electric toothbrush | AAA battery or USB-C | Battery / USB | No adapter needed |
Electric Shavers: Brand-by-Brand
Electric shavers are nearly as universally travel-friendly as toothbrushes. Braun and Philips Norelco have designed their chargers for worldwide use for decades.
| Brand / Model | Charger INPUT | Charger Type | Verdict |
|---|---|---|---|
| Braun Series 9 / 9 Pro | 100โ240V ~ 50โ60Hz | Clean&Charge station or charging cable | Adapter only |
| Braun Series 7 / 5 / 3 | 100โ240V ~ 50โ60Hz | AC adapter or USB-C | Adapter only |
| Philips Norelco 9000 / 7000 / 5000 | 100โ240V ~ 50โ60Hz | AC adapter | Adapter only |
| Philips OneBlade | 100โ240V ~ 50โ60Hz | USB-A charging cable | Adapter only (or any USB port) |
| Panasonic Arc5 / Arc3 | 100โ240V ~ 50โ60Hz | AC adapter | Adapter only |
| Wahl Professional clippers | 120V ~ 60Hz | AC corded | Converter needed (15โ25W) |
The exception: Professional barber clippers (Wahl, Andis, Oster) are often 120V only because they are designed for salon use in the US. If you travel with professional clippers, you will need a small converter like the DOACE LC-C30. Consumer-grade electric shavers from Braun, Philips, and Panasonic are all dual-voltage.
Water Flossers (Waterpik)
Water flossers are the one personal care device that frequently catches travelers off guard:
| Model | INPUT Voltage | Wattage | Verdict |
|---|---|---|---|
| Waterpik Aquarius (countertop, corded) | 120V ~ 60Hz | 45W | Converter needed โ or leave home |
| Waterpik Cordless Advanced (WP-560) | 100โ240V ~ 50โ60Hz | 2W (charger) | Adapter only |
| Waterpik Cordless Select (WF-10) | USB charging | 5W | Any USB port โ no adapter needed |
Travel tip: If you use a countertop Waterpik at home, buy the cordless model for travel. The cordless version charges via dual-voltage USB and takes up far less space. If you must bring the countertop model, a DOACE LC-C30 (300W) easily handles its 45W draw.
Beauty Devices: The Category That Requires Checking
Beauty devices are the most varied category. Unlike toothbrushes and shavers, beauty device brands are less consistent about dual-voltage design. Always check the charger label.
| Device Type / Brand | Typical Charger INPUT | Wattage | Verdict |
|---|---|---|---|
| NuFace Trinity / Mini (microcurrent) | 100โ240V ~ 50โ60Hz (USB charger) | 5โ10W | Adapter only |
| ZIIP Beauty (microcurrent) | 100โ240V ~ 50โ60Hz (USB) | 5W | Adapter only |
| CurrentBody LED mask | 100โ240V ~ 50โ60Hz | 10W | Adapter only |
| Dr. Dennis Gross LED mask | 100โ240V ~ 50โ60Hz (USB) | 10W | Adapter only |
| TriPollar Stop VX (RF) | 100โ240V ~ 50โ60Hz | 20W | Adapter only |
| Therabody Theragun | 100โ240V ~ 50โ60Hz (USB-C) | 15W | Adapter only |
| Foreo Luna (facial cleansing) | USB charging | 2W | Any USB port |
| Older/generic IPL devices | Check label โ some are 120V | 30โ80W | Must verify โ converter if 120V |
Most modern beauty devices charge via USB or have switching power supplies rated 100โ240V. The exceptions tend to be older IPL (Intense Pulsed Light) hair removal devices and some lesser-known brands. When in doubt, check the charger label.

The Key Pattern: Charging Type Predicts Voltage Compatibility
| Charging Type | Dual Voltage? | Examples |
|---|---|---|
| USB-C or USB-A cable | Always โ any USB port works worldwide | Philips OneBlade, Foreo, newer Theragun, Quip |
| Inductive/magnetic charging base | Almost always โ check the base's label | Oral-B, Sonicare, Apple Watch |
| AC adapter brick (wall plug) | Usually โ but check the label | Braun Clean&Charge, TriPollar, some IPL |
| Corded (plugs directly into wall) | Rarely โ usually 120V only | Waterpik countertop, Wahl clippers |
Recommended Products
DOACE 70W GaN Travel Adapter โ For the 95% of personal care devices that are already dual-voltage. Adapts the plug shape and adds USB-C/USB-A ports for USB-charged devices.
DOACE LC-C30 โ 300W Voltage Converter โ For the rare 120V devices (Waterpik countertop, Wahl clippers, some IPL devices). These draw under 100W, so the 300W converter provides ample headroom.
Frequently Asked Questions
Can I charge my Oral-B toothbrush in a European bathroom outlet?
Yes โ European bathroom "shaver outlets" are specifically designed for low-wattage devices like electric toothbrushes and shavers. They provide 230V through a special two-pin socket. Your Oral-B's inductive charging base plugs in directly (the two-pin plug fits without an adapter in most cases) or with a simple Type C adapter. The charger is dual-voltage, so no converter is needed.
My Sonicare charger has a two-prong plug. Will it fit European outlets?
The Sonicare inductive base has a Type A (US) two-prong plug. European bathroom shaver outlets accept two-pin plugs, but the pin diameter may differ. A small Type A to Type C adapter ensures a snug fit. Or simply use your DOACE travel adapter at a regular outlet.
I have a NuFace that charges via USB. Do I need anything special?
No. USB is a universal standard at 5V DC. Any USB charger or USB port anywhere in the world will charge your NuFace. If you bring a dual-voltage USB charger (like a phone charger or the DOACE GaN adapter), you are covered.
What about my Waterpik? I don't want to leave it home for a 3-week trip.
The countertop Waterpik Aquarius is 120V only at 45W. If you must bring it, a DOACE LC-C30 (300W converter) handles it easily. But for travel, we recommend the Waterpik Cordless Advanced (WP-560) โ it charges via dual-voltage USB, weighs a fraction of the countertop model, and takes up almost no suitcase space.
Are there any personal care devices that definitely need a converter?
Very few. The main exceptions are: (1) countertop Waterpik water flossers, (2) professional barber clippers (Wahl, Andis), (3) some older IPL hair removal devices, and (4) any corded device that plugs directly into the wall without a separate charger brick. Everything else โ toothbrushes, shavers, beauty devices, massage guns โ is almost certainly dual-voltage. When unsure, check the INPUT line on the charger label.
