I purchased the Phillips One that uses a AAA battery and has a small cover it’s much smaller than my sonic are but my gums are thanking me ….
You can do it for a lot less. A Sonicare One (that runs on a AAA battery) is like $15 and just as good as any other Sonicare i.e. really good. My last Sonicare rechargeable lasted -- I shit you not -- twenty years. But I got the One because it was good to have a good toothbrush at work as well as at home, plus it's nice not having to put the thing on a charger (or travel with the charger). Likewise, a generic water flosser that runs on AA batteries is like $40. My Walmart generic one has been going strong for a decade.
Get a Sonicare One. $20, takes AAA batteries, and lasts practically forever. I've got one at home, one for the office, and a backup one in my travel bag. I'll swear by Philips Sonicare. My first one lasted more than 20 years and they still sell replacement brush heads for it.
This. I have the phillips one with a AAA battery. I use a rechargeable battery.
Searching for the same thing, I ended up buying an AAA-powered Philips Sonicare One, and [this](https://www.amazon.com/dp/B0CFT759FP) USB-C rechargeable AAA battery.
Like many said already, look at the Phillip's Sonicare one, AAA version. Last a long time, slim, can be taken apart, packs well. That's my travel toothbrush and I love it.
Yes. I have the Philips One brush that uses a regular AAA battery. I carry a spare AAA battery with me but I haven’t needed it. It can go into checked luggage. It’s really small and doesn’t take up that much more room. It’s fine for 2 weeks.
