Shutter Precision (SP,) dynamo hubs are our most popular choice for integrated lighting and charging systems at Kissing Crows. We really like the SP hubs due to their low drag and exceptionally low weight. We also find the SP hubs to be more than durable and reliable enough in all contexts we've used them in. Shutter Precision makes fantastic dynamo hub generators.
If you're not familiar with dynamo systems they are essentially this; the hub generates power as the wheel rotates (as a magnetic generator,) and then transfers that as power output to your lights, charging setup, or both. There is no need for battery powered lighting if you opt for a dynamo wheel.
Some things to note - Almost all hubs work with almost all lights and charging systems, and almost all hubs have enough power to generate 2 lights at once or a charger. Every light and hub you find on Kissing Crows Outpost works well together unless otherwise noted. Another thing to consider: Generally, if you are running two lights and a charger you will be switching between the two systems for better transference of power.
