Prestige 9900 Series

I have a Sonicare 9900 prestige and the travel case is type c

I had my previous Philips toothbrush for 12 years until it broke down. It was at that time the most expensive model they had. Then I bought the prestige version and it broke down within a year. Now I'm using the 5300. Cheap and does the job. Can't tell the difference between the posh one and this £50 version. Philips quality has deteriorated so get the cheap one

Well, firstly, you can buy toothrush covers to put over the head of your brush which I use anyway and secondly I have a Philips Sonicare Power Electric Toothbrush 9900 mainly because of the USB charging case which works pretty well.

The Sonicare prestige or even the 9000 model has a travel case that can charge

Sonicare 9900 Prestige. Had it for 3 years now.

I looked specifically for one with a travel case, but those are usually the higher end (Sonicare 9900 and the like). I tried a cheap one from Concept but it cleaned noticeably worse than my Sonicare. Then last year I snatched a new Sonicare for 50 euros at a clearance sale and I'm very happy with it. This one has a built in USB A cable to charge.

It doesn’t meet your criteria because it uses a travel case to charge via USB-C but the Sonicare DiamondClean is amazing. I actually prefer the wireless charger at home (easier than plugging in a cable and the toothbrush itself is fully sealed) but the travel case is perfect. It’s small and has a spec compliant USB-C port. It also looks fairly nice. The only downside is that it’s very expensive.
