Nomad started as a KickStarter project in 2012 with a product called ChargeCard, a USB cable the size of a credit card. That project raised more than 10 times the requested startup costs, and launched Nomad onto the stage, now with a range of USB products.
Their latest product to ship is the NomadKey, an ultraportable USB lightning adapter the size of a house key. It is rugged and flexible while remaining infinitely portable. So small it ships attached to a greeting card sized mailer.
For $29.00 this MFi certified cable is the greatest accessory cable I have for on the go convenience. It and a full line of accessories are available here.
