Support for Alternative Layouts
This is a summary of how alternative layouts have been supported by kits such as Colevrak and Homing. It is not a discussion of alt layout performance and development, but if that interests you I highly recommend starting with Pascal Getreuer’s A guide to alt keyboard layouts (why, how, which one?). It’s a concise and comprehensive overview with links to some great sites that go deeper. He also has a separate Links about keyboards page. The Keyboard layouts doc he recommends explains layout goals and metrics in detail, summarizing the alt layouts discussed here as well as more than one hundred others. Sculpted-profile The majority of custom keycap sets are sculpted-profile (Cherry, SA, MT3, KAT, etc. - more on profiles generally here) so let’s start there. Because each row has a unique keycap shape, alt layouts require a unique keycap for each legend that moves off its QWERTY row. At first there were two The Dvorak layout was patented in 1936 by August Dvorak & William L....

Phones/tablets and their chargers operate off-spec (on purpose), for supplying more than 500mA. They do it for offering you shorter charging times. This is why your phone charges slower if you charge it from a PC, and this is why some PCs/laptops come equipped with "special" USB ports that can provide more than 500mA.
So, if you intend using this cable for charging your phone from a "plain-old" USB port on a computer (which will anyway deliver up to 500mA), you can safely order 3 ft long version (on 6ft, it's 4.6V already on a 500mA load). Longer ones will still work at the expense of increased charging time.
However, if you intend charging your phone via a source capable of 1000mA or more, be it a charger or a special USB port on a PC, you should choose 1ft option. Longer ones will still work at the expense of increased charging time (an example here: http://forum.xda-developers.com/showthread.php?t=2545497)
To answer your question; as a _backup_ cable, yes, it will work. Better keep it short though. You need to go for "USB A to USB micro".
