Little by little we are seeing electronic devices that make use of the principles of induction to recharge their batteries. Although the wireless Bluetooth keyboard and Magic Trackpad are not compatible with this technology, thanks to a cylinder-shaped battery and the Mobee Magic Charger we can recharge them inductively.
The price of the Mobee Magic Charger is $ 59,99 (about 42 euros) so it is still a bit expensive for a home user who does not cost anything to exchange batteries from time to time.
