Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. The LED indicate different working modes and functions. On power-up with no Qi device placed on the charger, the green and red indicators blink three times. Once a charging device, like a phone is placed on the pad, a blinking green indicates the ongoing charging process. Once the charging is completed, the green indicator stays on. A blinking red indicator might show an error or the charging device is not correctly or centered placed on the charging pad/coil. www.V-Juice.xyz –V-Juice –Emil-Geis-Strasse 33 –81379 Munich –Germany –www.V-Juice.xyz V-Juice Model 1.0

Operational Description

Description of Operation for Wireless Charger V-Juice FCC ID: 2AV3O-V-JUICE1 The device is an inductive charger for mobile devices like Smartphones, based on the QI technology. It uses electromagnetic induction to provide electricity to portable devices. Energy is transferred through inductive coupling. An alternating current is run through an induction coil in the charging pad. This makes an alternating electric current in the induction coil embedded in the portable device. The operating frequency range is 110 kHz - 205 kHz (depending on the load and load position). The device is able to detect foreign objects like keys or other metallic parts that have been placed on the transmitter coil. In case of a detected foreign object, the transmitter reduces its power or switches its magnetic field completely off.
