Picked up a new gadget last week, the iLoveHandles Trunk. This is a bendable USB/Lightning cable for charging the iPhone. The beauty of this design is that the Trunk can be bent into shape so as to support the iPhone when charging – very useful when traveling.
Bluelounge has a clever little cable too (the Kii) – this one is designed to fit on your keyring for when you need it. Very clever (and with a locking mechanism, so you don’t loose the important bit).
