Spektrum, part of the big Horizon Hobby family, keeps expanding its own Smart Technology lineup (that debuted last year). Now it’s the time of the S120 USB-C Smart Charger that features Spektrum Smart Charging technology in a small and simple to use platform. This 20W charger easily charges compatible Spektrum Smart batteries conveniently from almost any USB power source. When a Smart battery is connected, the S120 immediately detects the battery information and automatically begins to charge. Spektrum Smart charging is designed to be safe, intuitive and convenient.
Charging is really easy with the Spektrum S120 USB-C Smart Charger: just use the USB cable to supply power to the S120 Smart Charger from a USB power source. Plug in your Spektrum Smart battery (Lipo versions require the balance lead to be connected as well as the main lead) and the charger will automatically start charging. Monitor your charging status via a blinking purple or yellow LED. Once your charging is complete the LED will glow green.
