Create Your Own Credit Card Sized USB Multitool
If you have a lot of devices, you will always need different USB cables. Repairman Chris Robinson solves this problem by inserting four different USB cables into a credit card-sized case.
This small case includes a USB micro, mini, micro SD adapter and an adapter. Basically, it just strips the unnecessary things off each plug to keep them as thin as possible, and then solders everything together. The cables are inside the case, which has a handy magnet that prevents it from opening. If you always carry USB cables with you, this is an easy way to do it without taking up a lot of space.
