Product Description

The USB WORK is connected to the hub dynamo and harnesses the energy by delivering 5 V voltage and up to 500 mA current. An integrated, small buffer battery ensures that the power supply remains constant at 5 V even during slow travel and short stops. The USB WORK is therefore ideally suited for charging/operating USB devices of all kinds: Mobile phone, GPS, MP3 player etc. includes output cable with USB socket.


  • best suited for chargeing/operating USB devices of all kinds
  • Output: 5 V voltage controlled, short-circuit proof
  • Power: if buffer battery charged, max. 5 W, continuous up to 2.5 W
  • Idle power: 0.05 W at 30 km/h
  • Charging time of connected mobile devices (non-binding): from approx. 15 - 20 km/h comparable to charging time via power supply unit

Translated from French To the original

USB Werk mounted on Ortler travel bike equipped with a Shimano hub dynamo, used for charging a Samsung A10 smartphone operating continuously with the Komoot active application, on hilly terrain -speed sometimes <13 km / h- or in the plain, used on several outings: Maintaining effective charge or recharge over kilometers. The product, easy to install, meets my expectations. Note: Recharge not tested at night when the lighting is on.

USB Werk monté sur vélo de voyage Ortler équipé d'une dynamo de moyeu Shimano, utilisé pour la charge d'un smartphone Samsung A10 fonctionnant en continu avec l'application Komoot active, sur terrain vallonné -vitesse parfois < 13 km/h- ou en plaine, utilisé sur plusieurs sorties: Maintien de charge ou recharge effectives au fil des kilomètres. Le produit, d'installation facile, répond à mes attentes. Note: Recharge non testée de nuit lorsque l'éclairage fonctionne.

Smartphone is charged, if "screen always on" it gets the charge after all. I use Phone as Navi, this charger does a good job. However, the light should be turned off.

Smartphone wird aufgeladen, wenn "Bildschirm immer an" erhält es immerhin die Ladung. Ich benütze Phone als Navi, dies Ladegerät macht einen guten Job. Allerdings soll das Licht ausgeschaltet werden.

The installation according to the operating instructions was done quickly. During the test drive of about 1 km, the charge of my mobile phone increased by 1%. In August, the device will be used correctly. Let's see how it looks in continuous operation.

Die Montage nach Betriebsanleitung war ruck zuck erledigt. Bei der Testfahrt von ca. 1 km stieg die Ladeanzeige meines Handys um 1%. Im August kommt das Gerät richtig zum Einsatz. Mal sehen wie es im Dauerbetrieb aussieht.
