Guest post by Erica Rae Chong Many people have been donating blood in Azerbaijan recently. In fact, the country's blood donation rate jumped a whopping 335 percent thanks to this bracelet. Dubbed "The Donor Cable," the bracelet acts as a phone charger. When disconnected, the band forms a cable that can be plugged into two phones to transfer or "donate" energy from one to the other. There is even a smartphone app that helps find battery donors around you in case your phone's running out of juice. Nifty, eh? But what does this have to do with blood donation? Azerbaijan has highest rate of children born with thalassemia, a blood disorder that requires extensive blood transfusions. Unfortunately, there are never enough donors and hospitals often lack the necessary amount of donated blood. The Donor Cable is part of a campaign, created by Y&R Moscow for Nar Mobile, an Azerbaijani cellular network. On the inside of the bracelet is an inscribed message: "Donate energy to save a phone and donate blood to save a life." The bands were given away for free with any Android smartphone purchase at Nar stores across the country and mobile blood donation centres were set up outside to catch buyers while the issue was on their mind. The Donor Cable was the talk of the town when the campaign was launched and blood donations soared, all thanks to this one free gift.
