All our lights are designed to be USB-C rechargeable with Pass-Thru Charging to extend runtime, so the only way to charge them is through the integrated USB-C port. As a result traditional 2-wire dynamo setups can't be wired in directly as the power needs to be conditioned from AC to regulated DC voltage. Companies like SineWave make USB converters for dynamo hubs and PedalCell make bottle dynamos that have USB output built-in to them, as examples that would be compatible. 

For any of these setups, since the power output from the dynamo is dependent on the speed you're riding and the dynamo you're using, the amount of runtime extension is variable, but it is a good way for a touring bike to keep the lights on for multi-day trips.
