Short answer
Waterpik itself calls the white Waterpik Cordless Pulse 3100 (WF-20CD010) perfect for travel and small bathrooms. Its USB-C cable charges from a laptop, car, power bank or wall adapter, a full charge lasts up to 9 weeks, and Waterpik lists it as global voltage compatible. Pack your own USB wall adapter: one is not included, and neither is a travel bag.

Why the Cordless Pulse 3100 suits travel
It charges from gear you already pack
Waterpik says the Cordless Pulse 3100's USB-C cable (rated 5.0V DC, up to 3.0A) charges from a laptop, car, power bank or wall adapter. The cable in the box is USB-C to USB-A.
One charge can cover a long trip
Waterpik rates the Cordless Pulse 3100 at up to 9 weeks of use per charge, and its instruction manual says a full charge lasts up to 9 weeks with typical use. A battery light flashes white as the battery gets low and turns solid red when it needs charging.
It works on different voltages
Waterpik lists the Cordless Pulse 3100 as global voltage compatible, and its FAQ notes that many travel plug adapters also include USB ports.
It is compact and light
Waterpik lists the unit at 11.75 in tall with the tip fitted, with a base up to 2.50 in wide and 3.75 in deep, and a unit weight of 0.70 lb. The water reservoir is removable.
How to use it
- Charge for 4 hours before first use, using a USB wall charger (not included).
- Lift the flip top on the reservoir and fill it with lukewarm water.
- Insert the tip at the top of the handle and press firmly until it clicks into place.
- Start with the lowest setting and increase to your liking.
- Lean low over the sink, place the tip in your mouth, aim it toward your teeth and turn the unit on.
- Start with the back teeth and work toward the front, directing the jet at a 90-degree angle to the gumline; look into the sink, not the mirror, to reduce splashing.
- Turn the unit off and empty any liquid left in the reservoir.
