The worlds best-in-class Dynamo Hub Dual USB-C Power Converter

Optimized, perfected and engineered without compromise. With two USB-C ports and lots of smarts. For those seeking the best of the best, this is it when running a Dynamo system. Perfect space saver for lights or any other essentials on your bike! Weighs only 150 gram.


Internal Storage

Huge super-capacitors.

Hoovers up excess power, provides stability during slow riding and rough terrain, and provides 4 minutes of stationary power1. Features higher efficiency and 5000x life-span over lithium batteries, and works great in sub-zero temperatures.

limited to 4 minutes but may be less depending on charge state of charge and USB power consumption.



Full USB charging from 12kph.

Worlds highest performance. Power starts from just 6kph and most devices will charge from 10kph. More power is available as speed increases.

Full charging is 0.5A for USB2. Output measured using our automated test-rig (SON 28 QR dynamo).



Packed with incredible density.

Redefining what’s possible from dynamo hub power with a huge list of features packed into its small and light-weight body. Unbeatable in every aspect.



With smart status indicators.

Five blue lights are conveniently placed in the riders line-of-sight. Discrete patterns show storage level, how much power a USB device is consuming (and when charging is complete) and whether the second USB-C port is powered. Mount accessories directly onto the bar.


With a 5 year international warranty.

A tough aluminium body and brackets, a IP69 water-proof rating, and recessed USB-C ports for natural rain protection. It’s built to last a lifetime.


The Igaro S1 Pro is the world’s highest performing USB power converter and fuses together our advanced knowledge and experience with the very best technology. Use the Igaro S1 Pro with STVZO 3W dynamo hub and charge your USB devices on your next Munga / Freedom Challenge RASA /  Audax / Randonneuring challenge challenge, round-the-world tour or commute to work.

By integrating maximum-power-point-tracking and dual reactance tuning, the Igaro S1 Pro extracts every milliwatt of power out of the dynamo hub and does so at maximum efficiency, regardless of speed and riding volatility. This power is buffered into super-capacitors with 60 times the capacity of those found in high-end dynamo lights and which provides up to 4 minutes of standby power. With two USB-C ports designated for primary and secondary roles, power is first delivered to a phone or GPS and then surplus power is typically output to a power-bank.

With an all metal body which doubles up as an accessory bar and IP69 waterproof rating (keep the USB ports dry – all USB ports corrode when wet), the Igaro S1 Pro is made for long-term use. It works at any speed, generates no heat and comes with a 5 year international warranty.
