The Mu plug open
The designer of a folding power plug has turned the prototype into a USB adapter, the Mu, that can be used to recharge devices such as smartphones, tablets and cameras.
The Mu, which went on pre-order on Friday, reduces the 4.5cm depth of a traditional three-pin plug to around 1cm using a pivot. The live and neutral pins rotate and the sides fold down to take up 70-percent less space, manufacturer Made In Mind said in a blog post.
Min-Kyu Choi first showed off the folding plug design in 2009, before joining
forces with Made In Mind. The PVT technology used for the pivot has been in development for three years and is
protected by six global patents, according to the company.
"I was frustrated by the dimensions of the traditional plug, and felt that the existing unit, which dates back to 1947, was out of touch and incongruous with modern design," Choi said in the blog post. "My idea was very simple — redesign the plug to bring it in line with the clean look and feel of today's technology, without compromising functionality."
The Mu measures 14mm x 55mm x 60mm and is fully certified to comply with British Safety Standards regulations, according to Made in Mind.
