Best Electric Toothbrushes for Travel

What separates the best electric toothbrush for travel picks?

Cleaning performance carries the most weight in our scoring (35 points), and it splits this page cleanly. The iO Series 9 and iO Series 5 both hit 88% plaque removal in our disclosing-tablet test, the Sonicare DiamondClean 9000 sits at 85%, the ProtectiveClean 6100 at 83%, and the quip at 72%. Price runs the other way: $300, $100, $230, $110 and $40.

Travel gear is the second split. The Series 9 uses a magnetic charger and a power-bank travel case. The DiamondClean 9000 and ProtectiveClean 6100 both ship with USB charging travel cases. The Series 5 includes a travel case. The quip skips the charger entirely — three months on one AAA battery, with a cover that sticks to a mirror.

Head cost is the quiet one. iO heads run about $8 each, DiamondClean 9000 heads about $10, and quip heads $5 delivered on subscription.

What should I check before buying a travel toothbrush?

Work down the scoring criteria and match them to how you actually travel.

• Cleaning performance (35): the two iO brushes lead at 88%; the quip trails at 72%.
• Comfort and pressure control (20): the Series 5 light ring shows too much, too little and just-right pressure. The quip has no pressure sensor.
• Battery and build (15): the ProtectiveClean 6100 runs two weeks per charge; the quip runs three months on one AAA.
• Replacement head cost (15): $8 for iO, about $10 for DiamondClean 9000, $5 for quip.
• Modes and app (15): the Series 9 tracks all 16 zones in real time. The DiamondClean 9000's coverage map caught spots our testers missed. The Series 5 app coaching is basic, and the ProtectiveClean 6100 has no app at all.

Two trade-offs worth naming. The Series 9 costs $300 for the same 88% clean as the $100 Series 5. And the DiamondClean 9000's brushing modes are more than most people use.

Oral-B iO Series 9

For the traveller who wants the colour screen, seven modes, 3D tracking and a power-bank travel case, and will pay $300 for them.

Philips Sonicare DiamondClean 9000

For someone who wants 85% plaque removal with the gentlest feel of the high scorers, a USB charging travel case and smart head recognition, at $230.

Oral-B iO Series 5

For the shopper who wants the 88% clean and the pressure light ring without the flagship price — $100, with a travel case.

Philips Sonicare ProtectiveClean 6100

For a two-week battery, a pressure sensor, BrushSync head reminders and a travel case at $110, and no app to bother with.

quip Electric Toothbrush

For the light packer: $40, one AAA for three months, no charger, and $5 subscription heads.

If cleaning matters most and you want to spend $100, the Oral-B iO Series 5 matches the Series 9's 88% plaque removal and adds a pressure light ring. The Sonicare DiamondClean 9000 suits anyone who wants 85% cleaning with the gentlest feel of the high scorers and a USB charging travel case. For the lightest bag, the quip runs three months on one AAA with no charger to pack.
