The modular smartphone makes a comeback, sort of, as a Chinese vendor you've probably never heard of unveils a rugged phone with two surprising accessories.

• Oukitel's third smartphone to launch at CES is the WP300 Pro
• It's a rugged smartphone that claims to be modular
• One of its modules is a powerful LED light and the other is a headset that can be transformed into a smart watch.

The best rugged smartphones are designed to withstand extreme conditions and harsh environments, making them ideal for users working in industries such as construction, mining, and outdoor exploration, as well as adventurers who need a device that can handle difficult activities.

These phones are made with reinforced frames, durable materials, and shock-resistant components. While the most interesting thing about them is often their ability to withstand punishment, some models also include features like high-capacity batteries, enhanced GPS functionality, and even thermal imaging or night vision cameras.
