No charging cable for USB-C but you already have one for your phone - no sweat! - Excellent device and super easy to travel with and feel like you're getting a full sized water flosser in a mini sized travel pack. There are a number of settings with a starter level to help your teeth and gums get used to the pressure without damaging the gums. The size of the COSLUS is compact enough to take on all your travels. The cordless device is easy to charge and lasts a long time. I highly recommend this traveler model for all your travel needs. I went to Japan with this device for two weeks and performed like a champ! The water capacity is perfect for my mouth and while it may seem small, you can refill it effortlessly. By far the best value for the money spent. I would buy again or even as a gift! Review: Cute, compact, and functional - Perfect little travel water flosser! I ordered this last minute for a two week European trip and it was perfect. It arrived in less than 24 hours of ordering. It’s compact, yet holds enough water to do a thorough once-over of my teeth. I refill it a second time when I wanted a extra thorough cleaning. It hasn’t needed a recharge yet and I’ve used it a few times a day for a month or so now. It’s so much better than my older travel water flosser which was bulkier and heavy and took AA batteries that wore out quickly and depleted the water pressure gradually - this one maintains the full pressure despite not having been recently charged up. What an improvement! I also really like the pink/purple color I got - it’s cute and matches my bathroom’s color scheme. ## Features - Easy-go, Mini Ultra-Portable Design for Frequent Travelers: Weight comparable to common smartphones.
