Oukitel is probably best known for its smartphones with ingress-protection ratings such as IP68/69K, a reinforced-style casing and large batteries for prolonged screen-on time. These features also apply to its latest product, the RT1 - however, this one has the OEM's largest display to date, at 10 inches. Oukitel will launch it for outdoor-life fans later in November 2021.
