The HOTA T8 Ultra is a compact, high-power 1-8S AC/DC smart charger featuring advanced GaN + SiC power technology. It combines a built-in AC power supply with up to 650W DC charging power, making it a versatile charger for RC helicopters, airplanes, cars, FPV systems and other high-capacity battery applications.
Unlike the original T8, the new T8 Ultra can be powered directly from a standard AC outlet, delivering up to 300W without an external power supply. When connected to a suitable DC source, output increases to as much as 650W at 22A.
GaN + SiC Technology
The T8 Ultra uses modern GaN (Gallium Nitride) and SiC (Silicon Carbide) power technology to provide higher power density and improved efficiency in a compact package. This allows the charger to integrate a powerful AC power supply while keeping overall size and weight low.
