Michael always has his Sandberg ACTIVE flashlight with him when he's camping, hiking, canoeing or simply on the beach. When it's not in his pocket, it's in the glove compartment of his car. With seat belt cutter, emergency hammer and flashing light, it's an extra safety feature.
Not only is it waterproof, impact- and dust-resistant, it also has a very powerful beam. There's even a hefty powerbank built-in that can charge a typical smartphone four times from 0-100%.
