Emergency Backup Phone Charger Micro USB 2XAA

via Jaycar
Never get caught in an emergency without a phone charger again! This device takes two standard AA batteries to provide a Micro USB charging outlet. It may not fully charge your phone, but it’ll get an average Android phone (with a 2500mAh battery) to 40% in around half an hour. AA alkaline batteries have a long shelf life, so provide an excellent backup solution. It uses a clever DC-DC converter to increase the AA battery voltage and make it suitable for charging.
