Humanscale's NeatCharge lets you turn almost any surface into a wireless charger

Humanscale's approach to wireless charging gets rid of the charging tray/pad entirely. Rather than having another device clutter your desk, table, or nightstand, NeatCharge hides under almost any surface so you can remove any unsightly or space-hogging devices out of sight and there's a sticker included to display where the charging surface is. NeatCharge is compatible with any Qi-certified device and can charge devices at speeds of up to 10W.
