I've tried smaller models from Omrom and Panasonic but they aren't as good at giving that "clean" feeling. I went back to traveling with a Sonicare 4100 which has a lighter Lithium Ion battery and slightly slimmer handle. It only needs to be charged every few weeks when used and I also swapped a dying DiamondClean at home for another 4100. I periodically check 3D printing sites to see if I can find a cover for the button similar this one for an older model https://www.thingiverse.com/thing:2495721. I also DIY'd a cap for the stem out of a straw and some sugru but a pen cap would probably also work - just something to prevent it from stabbing through my toiletry bag or getting bent.

There's a USB-C chargeable toothbrush by Aiwejay which isn't much smaller but comes with a small cap
