Wireless Car Charger Jarvis with Intelligent Detection Function – the true "smart" device from the STARK brand lineup! Upon connecting to a 5V~9V DC power source, the device automatically checks the voltage parameters. When a phone is within 5-10 cm of the device, the automatic detection function opens the clamps and secures the phone once placed. To remove the phone from the charger, simply touch the back of the device where the touch sensor is located, and the clamps will automatically release, allowing you to take your phone. Jarvis features protection against overvoltage, overheating, magnetic fields, and short circuits. In case of any malfunction, the device will automatically shut down. It complies with the Qi wireless charging standard and supports devices such as iPhone 8, iPhone X, iPhone 8 Plus, Samsung S6, S6 Edge, S7, S7 Edge, S8, S8+, and S9+. For devices that do not support wireless charging, a Qi-compatible wireless receiver must be purchased separately.
