FAQ

  • Can I purchase the Mu® from overseas?

    We are currently only shipping to addresses within the UK and Ireland and, unfortunately, we can’t take payment from customers who are based outside of the UK. But we are planning on launching the Mu in some overseas destinations in 2015/2016. Sign up to our mailing list and we’ll keep you updated.

  • Will you be launching other Mu® products?

    Yes, we’re constantly coming up with ideas and developing new products within the Mu® range. For more information you can sign up to our mailing list or follow us on Twitter and Facebook to be the first to hear what’s coming next…

  • Is the Mu® USB charger being sold in shops?

    The Design Museum in London stocks the Mu® USB Adapter. We have also released 3 Limited Edition Mu® USB Adapters, which are only currently available at the Design Museum Shop, London. 

    The Mu® is also available to buy from the Conran shop, some O2 stores across the UK, and soon to be available from Maplin – more coming soon

  • If I want to buy a lot of them, can I place a bulk order?

    Yes, of course. You can place an order for as many Mu USB chargers as you need.

  • Has the Mu® been independently tested and does it comply with British Safety Standards?

    Yes – the Mu® USB Charger has been tested by recognised certification organisations and has the full pre-requisite approvals for CE certification.

  • Why has the Mu® changed from the original folding plug concept?

    After revealing the idea in 2009, designer Min-Kyu Choi’s ‘Folding Plug’ concept became a viral phenomenon. Min-Kyu joined forces with Matthew Judkins, a business creative, to form Made in Mind – the company that would commercialise the concept and champion other pioneering designs. Made in Mind started with the Folding plug design concept and adapted and developed it to make the product commercially viable. We rigorously tested the product scope, applied market and industry considerations, and prepared the design for its commercial manufacturing processes and certification. The result is the revolutionary Mu® USB Charger – the first of a range of smart power options for design enthusiasts.

  • Can I use the Mu® to charge my laptop?

    This is unlikely because laptops normally require more power than USB chargers can provide. However, we are working on a Mu laptop charger – sign up to our mailing list and we’ll keep you updated.

  • Can I use the Mu® abroad?

    Although our Mu® USB Chargers have been designed for use in the UK only, you can use them with a travel adapter as you would any other plug. 
    Also in 2015, we will be launching a Mu® international system, which is designed to work exclusively with the Mu® system products only. 
    • Exactly how flat does the Mu® fold down to?

      The folded dimensions of the Mu Classic are a sleek and minimal 14mm x 55mm x 60mm.
      The folded dimensions of the Mu Tablet and Mu duo are only a fraction longer in length at 14mm x 55mm x 72mm

    • What is PVT technology?

      PVT is the technology we’ve developed that allows a three-pin electrical plug to a pivot, enabling the live and neutral pins to rotate. By using PVT technology, the MU reduces the standard UK plug by over 70% in size, whilst still being operational in the open and folded positions. PVT, a technology that is central to the Mu® USB Adapter and the Mu® range of products, has taken 3 years to develop and is protected by six global patents.

    • Where did the name ‘Mu®’ come from?

      When it was unveiled in 2009, the response to the folding plug concept was phenomenal. The fan base that formed has faithfully followed and championed its development ever since. Which made us think – ‘who better to help us name it?’ So in August 2010 we went to our community to ask for suggestions for the name of the final design. Robin Freeman from London entered our competition on the 3rd August 2011 with ‘mu’ (Greek for small/micro) –a name that we feel is as simple, elegant and iconic as the product itself.
