Review: Philips Sonicare DiamondClean Rechargeable Sonic Toothbrush
The chrome like round styled base is rated 100-240V, 50/60Hz, with a 1.4-1.6W power draw and a cable length of around 3 ft. A number of pads on the underside of the base help prevent the unit slipping around. A centre depression within the charging base is for seating the glass tumbler which is required as the toothbrush is not designed to stand in the charger base unsupported (although there is a version that ships with an adaptor instead of the glass).
The glass tumbler is pretty substantial and chunky, almost squared off like a larger version of a shot glass, and it sits easily onto the charging stand. The glass tumbler does not click into place onto the stand but rests on top after which the toothbrush can be stood within the glass for charging. There is no need to click the toothbrush into anything although one would imagine the glass needs to be dry (and kept free of any other metallic objects) as the induction charging works through the glass.
This arrangement keeps everything neat as there are no connectors (other than the power lead on the charger base) and a full charge, according to Philips, should last around three weeks depending on use.
