The Supernova ThePlug III Dynamo USB Charger is a thoughtful and discrete upgrade to your existing dynamo system. You are your own power plant with ThePlug III. It is simply wired to your front hub and is capable of charging your USB-A devices with 5A at 8 mph. ThePlug III transfers dynamo AC to USB spec, with not upper limit on charge speed. While Supernova does not recommend charging with simultaneous lighting system usage we have done it without issue.
