First there was the "ChargeCard". Now there's the "ChargeKey".

Last year at CES we were introduced to NOMAD’s first product, the ChargeCard. The ChargeCard, about the size of a credit card, has a flip out cable that becomes a real small USB charger for your smart phone. People were so interested in it, NOMAD had $161,897 pledged even though their goal was $50,000. At CES 2014, the company released their new ChargeKey. This is an even smaller charge cable. Billed as the world’s most portable USB cables, ChargeKey is available in two versions. One for iPhone 5, and one for micro USB devices like the Galaxy S4 & S5. Shaped like a key, ChargeKey fits onto any keychain. Use it for charging from any USB port (works just like your standard smart phone cable) with full data transfer when connected to a computer. Now no matter when you go, you can always have a charge cable handy! They’re $25 each.
