My husbands Phonaks couldnt fit under my smaller one in its case. Which is the whole point of drying, cleaning while the hearing aid charges. Oticon charging isnt a case so no issue with the smaller one with it. The charger with the bigger one has a usb port to plug your hearing aid charger. One usb port for the dryer of course. I loved that I could use a portable charger to use with this dryer to dry and disinfect my husbands hearing aids. Not having to struggle to plug mine in behind the bed. Plus didnt want him claiming it as his. As now I use the smaller one to nightly dry and clean my Apple Watch. And the bigger one for my hearing aid. Plus if I ever have to get another pair at least I could be covered having enough room inside to put it all under the dome. Oh, nice surprise inside the box, m looks like the seller had wrapped the charging stuff box with a big cloth that can be used to clean many things like glasses, hearing aid, tablet screens. Oh, and no heat using this dryer, a huge deal for me after doing research on those that use heat and others reviews.
