Keeping our smartphones charged up for when we need them most is something we're always considering, subconsciously or otherwise. As such, the third-party accessory market makes an absolute killing in flogging docks, retractable cables, charging mats, juice packs, and other such products. Considering there are so many different types of charging accessories available, you might have thought the scope for innovation in this field was somewhat limited, but iLoveHandles' "Trunk" Lightning cable for the iPhone 5 proves this not to be the case.
