This Steinbeck Charge 41 cm Desk Lamp is a contemporary style table lamp that includes a wireless charging pad with Qi inductive charging technology. Many smartphones have Qi technology built in, so just place your phone on the pad and it will charge right up. No cords, no mess. This is unique in that you can use this charging pad, the USB, and the light all at the same time with maximum efficiency of all three. A simple touch switch on the base turns the lamp on and off. This sleek charge pad design that is flush with the surrounding area provides an attractive charging station with easy access to your phone while it's charging. Just plug in the lamp and the charger will work. The light on the lamp does not even need to be turned on. This wireless charging pad will charge your phone through most materials, so you do not even need to remove your case. Only metal will hinder the function of the charging pad to charge through the case. If your smartphone doesn't support Qi wireless charging, you will need to purchase a Qi compatible case, which is sold through a variety of retail channels.
