The travel version of the best wireless 3-in-1 charger on the market for mobile accessories. Despite its compact size, the STM ChargeTree Go can charge up to three different devices simultaneously – a phone (up to 5 mm thick in a protective case), an Apple Watch, and wireless AirPods and AirPods Pro headphones. Simply press lightly on the module on the side of the case after unfolding the charger, and the watch charging lever will automatically extend. Once the charger is assembled, you can use it like traditional Qi chargers to charge your phone in a horizontal position. To properly charge all three devices, a power adapter with a minimum output of 20 watts is required. The STM ChargeTree Go charger is designed for both iPhone users and owners of other smartphones that support Qi wireless charging (e.g., Samsung, Xiaomi, OPPO, and others). The built-in LEDs light up when the device starts charging and turn off after 30 seconds. The STM 3-in-1 charger comes complete with a 1-meter long USB-C cable.
