Best portable water flossers for travel

Top pick: Waterpik Cordless Pulse 3100 — a genuinely travel-sized rechargeable from the brand that made water flossers a thing, with a sealed tank that won't leak in a bag and a battery that lasts a trip rather than a night.

Who the others suit:

• Cordless Advanced 2.0 — if you want a proper travel kit: tip storage case and travel plug included, and it's the most capable of the compact ones.
• Rechargeable Cordless Water Flosser (Amazon) — the budget pick; magnetic charging and weeks of use per charge, though the build feels cheaper.
• Cordless Express — a simple, light Waterpik for short trips if you don't need many pressure settings.
• Cordless 1100 — better for a big bathroom counter than a suitcase; the tank is bulky.

Skip the plug-in and countertop models here — they're not travel-friendly.
