Description Power USB devices using a 3W bicycle dynamo hub from Shimano, Schmidt (SON) or SP and an Igaro D1. Commuters, audaxers, tourers and adventurists worldwide rely on the Igaro D1 to reduce or eliminate the need for mains or battery power. Offering class leading efficiency, compatibility and construction, the Igaro D1 is built in the UK to an unrivaled specification and comes with a 5 year international warranty.

The Igaro D1 offers an outstanding 88% end-to-end efficiency rating meaning USB devices power at lower speeds or at faster rates. High efficiency (combined with compatibility technology) is why the Igaro D1 is reputed for powering USB devices when others can't.

The Igaro D1 is crafted from a single piece of lightweight titanium just 70mm x 13mm x 8mm in size. The bespoke circuitry housed inside each unit utilizes components rated for a 25 year working life and a -40c to 80c temperature range to ensure operation in any season.

Plastic injection moulding (most Igaro D1 competitors) is fast and thus cheap, while Igaro D1 construction is slow and thus expensive. Unit assembly includes insulating the PCB from the casing, silicone filling the unit (for water ingress and vibration protection), and applying multiple water and flex resisting wraps. Subsequently the Igaro D1 is IP69 rated (it will continue to work while submerged under water and it won't be affected by condensation).

The Igaro D1 includes over-voltage, over-heat and short-circuit protection. Power continues no matter how fast the operator rides. Digital frequency monitoring enables power at the lowest possible stable speed and prevents connected USB devices switching on/off rapidly at very low speed, resulting in superb USB device compatibility.

USB ports are configured in power adapter mode and feature gold plated connectors and a water draining design. A limitation of the USB design means they won't work in outdoor conditions forever, however there is a free replacement service (excluding postage) for when they fail.

The Model 5 uses the same electronics as the previous models but removes the external capacitor making the Stability Bank accessory mandatory (d1acc01, included). The USB port has been moved to the other end of the device.

This model features an increased delay from stable power detection and a further five second delay from cold start. These delays allow the rider to build speed before power is applied increasing the chance of high power mode availability to the USB device.
