Previously known as Ark, the Prelude is a portable wireless charger for smartphones and smartwatches. Using the Qi (inductive power standard), the Prelude recharges mobile devices through contact with its top surface. The Prelude is compatible with a range of mobile devices, including smartphones, tablets, and wearables. Devices with built-in Qi wireless charging (such as the Moto 360 smartwatch from Motorola) can be charged with the Prelude out of the box. The Prelude charges non-Qi-compatible devices (such as the Apple iPhone line) by installing a wireless charging patch or case onto the device. BEZALEL's campaign was named a top 10 Kickstarter campaign of 2014.
