Best advice, get a full second brush - same model and brush. The excess items not needed for your daily use, put in a cabinet and leave it there. If your charger ever breaks (as it is a glass charger cup), then you’re certain to have a working replacement. Or another if you choose to travel. Also, at one time there was a model that had a storage spot for 2 brushheads, and a single motored unit. I’d recommend that model if you’re tight on space, and set your glass one aside for travel. Did you gather I travel a bit - having the available brushes, and chargers have helped me out over the past 10 years of using a Sonicare brush.. for both my spouse and I.
