We know people rely on their iPhones to keep them connected, and sometimes need an extra charge to get them through those longer days. At tech21, we challenged ourselves to develop a truly safe battery solution, free from the problems that today's batteries bring. Using unique technology, specifically designed for maximum safety, the result is the world's first ultra safe charging case.
