The Plug III is a USB power supply which is powered by a bicycle’s dynamo hub.

The Plug III can be used on cycling tours of all kinds. There are no restrictions regarding the range of use, i.e. it can be used on trekking, touring, city and road bikes as well as on mountain bikes.

Not wired-in directly. The Plug III is powered by alternating current, as provided by a dynamo hub. It is not possible to connect it to the DC power supply of an e-bike battery. If your e-bike is equipped with a dynamo hub this can of course be connected.

Yes. The Cinq Smart Power Pack buffer battery is optimally tuned for operation with Plug III. 

Yes, if the Plug III is connected parallel to the light. It is important to note that both the light output and the power of the plug are reduced if both consumers are switched on at the same time. Therefore we recommend "either/or" operation.

Yes, since the Plug III is bolted to the bike, it cannot simply be removed. For further theft protection we recommend the use of Hexlox.

The Plug III is our device with integrated buffer battery.

The Plug III can theoretically be used in combination with any device that is capable of external USB operation or which can be charged via USB and operated simultaneously. The Plug III is especially suitable for outdoor GPS devices. For operation on smartphones we recommend the Plug5 Plus because of its integrated buffer battery.

Yes, you can use it with an iPhone without a special charging cable. The exact functionality of your smartphone depends on the power requirements of your device. For charging or operating most smartphones we recommend the Plug5 Plus or the combination of the Plug III with the Smart Power Pack.

No. Any standard USB cable with a suitable plug for your device can be used.

Yes, a fully charged smartphone requires less power and therefore charges at lower riding speeds than a device that charges and operates simultaneously.

Yes, when charging devices, we recommend switching them off for faster charging. Here, too, the charging performance depends on your device and its battery.

No, as long as your device meets the USB specification.

Not if your device uses a modern lithium ion or polymer battery. Although these only have a certain number of charging cycles, it is irrelevant whether the battery is charged in one go or in many small steps. If, however, you are frustrated by notifications when a device starts and stops charging, we recommend the use of the Plug5 Plus or our buffer battery "Smart Power Pack II", which enables continuous charging.

The electronic unit of the Plug III is waterproof, the USB plug is protected against splashing water. The connector itself is not pretected when a device is plugged in. Avoid high pressure and streaming water at all costs.

Not necessarily. Depending on the where you ride and the weather, the metal contacts may corrode slightly. However, the formation of a "rust film" does not impair the function. For cleaning you can use a cotton swab with some alcohol.

In this case, your device requires too much power which cannot be provided at lower speeds. We recommend using the Plug5 Plus or Smart Power Pack.

First, check if your light's on. If this is the case, the light has higher priority. Alternatively, in this case your device may require too much power which cannot be generated by the dynamo hub. We recommend using the Plug5 Plus or the Smart Power Pack.

Check that the wiring is correct - see the user manual. Also check that the dynamo contacts are connected correctly.

First, check if your light's on. If this this case the light has higher priority. Alternatively, in this case your device may require too much power which cannot be generated by the dynamo hub. We recommend using the Plug5 Plus or the Smart Power Pack.

No, this is not possible.

We recommend the Smart Power Pack and we have not tested other Powerbanks.

No. The Plug III needs virtually no power if no device is plugged in.

The green LED indicates that the dynamo has enough power to supply the USB port with 5V when the device is not plugged in. When the device is plugged in, an illuminated LED means that the device is supplied with sufficient power. When the LED is flashing, your speed is not sufficient to provide the power required for the terminal device.

The Plug III checks at certain intervals whether the dynamo is providing enough power to operate the connected device. If the LED goes off, you are moving too slowly, and the Plug III checks the status again after a few seconds.

This depends on various factors, including the dynamo hub used. The required 5V are always maintained. For example with 6V/3W and 26" wheels, charging is possible from approximately 5km/h. The actual function depends very much on the connected device and its power consumption. As a rough guideline, the speed required to power GPS devices is approximately 10 km/h, however, in our tests some smartphones with very high power consumption were charged only above 25 km/h. In order to make optimal use of the dynamo's low power when riding slowly uphill slowly or to counteract charging interruptions during traffic light stops in city traffic, we recommend using our Smart Power Pack buffer battery - this can be charged from 7 km/h!

The power provided depends on the speed. For reference, the output voltage of the Plug III is always 5V. The USB 2.0 nominal current of 500mA at 5V is provided from approximagely 12 km/h. For many devices this is the maximum charge current, and a higher output would not charge the battery faster. This is not the case for modern smartphones.

The dynamo should provide a power of 3W at a voltage of 6V. Older rim or tire models and 1.5W dynamos usually do not deliver enough power.

In any bike with a stem that meets the 1 1/8" standard, except for bottom closed carbon forks. The Plug III cannot be used on bikes with Speedlifter, as it is not possible to run cables through the head tube.

The Plug III must be connected in parallel to the lighting system.

Yes, but in case of any doubt you should have the installation carried out by a dealer or specialist.  With some manual skill and the appropriate tools listed in user manual, installation should not be a problem.

The USB socket of the Plug III should be facing forward during installation. In this orientation it is optimally protected against impact damage when the bicycle falls down. The Plug III should be kept in this orientation even if you turn the handlebars for transport. If the Plug III rotates during this process, it is possible to damage the wiring.

No. When retrofitting your existing bike, note the removal/modification of the Star-nut. On our Youtube channel you will find a video on how to remove it.

Yes, included with the Plug III is an Aheadset expander. This simplifies assembly as well as installation and removal. When retrofitting your existing bike, note the removal/modification of the star-nut.

Yes, simply adjust the headset preload as you would on a normal topcap / Ahead system.
