The Plug5 Pure is a USB power supply which is powered by a bicycle’s dynamo hub.

The Plug5 Pure 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 gravel bikes as well as on mountain bikes.

Not wired-in directly. The Plug5 Pure 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.

The Plug5 Pure without internal battery allows flexible mounting options on all kind of bikes. The Plug5 Pure  is our device with integrated buffer battery.

Yes. The Cinq Smart Power Pack buffer battery is optimally tuned for operation with Plug5 Pure. 

Yes, since the Plug5 Pure is bolted to the bike, it cannot simply be removed. For further theft protection we recommend the use of Hexlox.

Yes, if the Plug5 Pure 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.

Due to enormous market diversity, it’s impossible to verify every light combination separately. However, we know in a few cases customers experienced issues with Busch + Müller IQ-X light. Therefore we don’t recommend this combination.

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.

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.

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.

The Plug5 Pure 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.

Yes, you can use it with an iPhone without a special charging cable. The exact functionality and charging capability of your smartphone depends on the power requirements of your device.

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

The electronic unit of the Plug5 Pure is waterproof, the USB plug is protected against splashing water by the rotary door. 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.

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.

This is very low with the Plug5 Pure, approx. in the range of 10km/h. But the charging current depends on your riding speed.

No, this is not possible.

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

No. The Plug5 Pure needs virtually no power if no device is plugged in.

The LED indicates that the dynamo has enough power to supply the USB port when no device is plugged in. When the device is plugged in, a pulsing LED means that the device is supplied with sufficient power.

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 hub dynamo used or the wheel size. The smaller the wheel, the lower the required speed. The Plug5 Pure provides from approx.12km/h enough power to operate or charge a Smartphone or a GPS device.

The power provided depends on the speed. The Plug5 Pure provides a maximum of 700 mA from about 12 km/h.

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.

We use a USB-C connector, because it allows a more compact design and the connector can be connected in any orientation.

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

In any bike with a stem that meets the 1 1/8" standard, except for bottom closed carbon forks. The Plug5 Pure cannot be used on bikes with Speedlifter, as it is not possible to run cables through the head tube.

The Plug5 Pure 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 Plug5 Pure should be facing forward during installation. In this orientation it is optimally protected against impact damage when the bicycle falls down. The Plug5 Pure should be kept in this orientation even if you turn the handlebars for transport. If the Plug5 Pure rotates during this process, it is possible to damage the wiring.

Yes, included with the Plug5 Pure 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.
