I got this one Aquasonic Vibe Series... https://www.amazon.com/dp/B0C1CYX2CT?ref=ppx\_pop\_mob\_ap\_share specifically for travel about two years ago. I use it but ugh. The case is so obnoxiously big and the case has no option to plug it in for charging. Even when fully charged, the vibration is pretty weak. I have a Sonicare that I love for at home use and always wish I had that instead, but it didn’t come with a case. Ages ago I had a Sonicare that have an unattractive but fairly streamlined white case that had a direct plug in for charging. These days I always eye the simple manual toothbrush and wish I could convince myself to travel with one of those instead. But I am one of those who wants to water floss, manual floss, and brush with an electric toothbrush every night. Have not found a good solution.
I use and love the Aquasonic Vibe. I paid about $35 for it. It comes with 8 replacement heads, a travel case, 4 cleaning modes, and warranty. It also times your brushing in 30 second increments for each part of your mouth. The replacement heads are $30 for 8 but I won't need to buy more for a long time (the company says it is 2 years worth that comes with the toothbrush initially) so i thought that was do able. I finally bought mine after my best friend bought his last year and recommended. I wish I would've have gotten one sooner. I personally like it better than my Phillips Sonicare and I used that thing for the last 15 years.
I bought an auquasonic black series electric off amazon for like 40$ I'm pretty happy with it.
I got a $40 Aquasonic Black Series from Amazon after seeing the positive reviews. I’ve had it about 9 months and no complaints other than the hinge on its case broke but it still closes. It comes with a ton of the replacement brushes too and I only have to charge it like once a month it feels like. It’s one of the better investments I made but I’ve never had one of the $100+ ones.
I use an Aquasonic Black Series and I like it a lot. Plenty of power but it’s big for travel. Uses their own wireless charger but I don’t know how long a charge lasts - more than a month.
Not exactly small or light, but I use an $40 Aquasonic at home, and I like it so well, I may start taking it on trips. It comes with a travel case (& 8 brush heads), and uses a proprietary "mag-safe"style inductive charger but I haven't found out how to run it out of charge (rated at 2xday for 4 weeks) so I would just not take the charger for any of my usual short trips.
Aquasonic black. Inexpensive, comes with 8 replacement heads and a travel case. Battery lasts for a month per charge. At least
Been loving my aquasonic black. You don't have to buy a charging brick, battery lasts for over a month in a single charge, it comes with 8 heads and a traveling case, and has more oscillations per minute than the sonicare 4100. I believe it's also cheaper than the 4100 right now.
