One of the best things about using a Core or Photon is the fact that you can program and run it wirelessly without being connected to your computer. All by it's lonesome your Core or Photon will still need juice! This Spark-loving USB power adapter works just like the adapters you're used to and will give any of your USB devices (like your Spark boards!) up to 1A of power. It’s compact, light weight, and easy - the classic Spark way. So come on. Give your devices the 5V, 1A it deserves. Specs: USB power supply for 5V devices Input - 100-240V-50/60Hz, 0.3A Output - 5V, 1000mA Does not include USB cable
