The USB Werk is a superb little device which when working provides good charging at all speeds for GPS devices and the on bike devices Ive wished to charge. It utilises a small cache battery within the unit which ensures a constant output to the device being charged. However, it is the cache battery that can be the USB Werks undoing. It needs to be kept charged. If the battery charge falls below a certain value then it wont charge again. The USB has no means to determing the charge held in the battery and has no means to charge the battery from any source other than a dynamo. I have had two USB werks now that have failed. One provided with a dead battery and the second failed after I hadn't used it in a recent enough period and the battery drained flat. Use it regularly and constantly and keep it charged it'll serve you well. Don't and it becomes a consumable item.
Easy to use and it works

I ran this with a light and to charge my phone or spare battery. I was using an iphone6 with the light on most of the time. If you keep the speed up it works. Over time the phone charge would reduce to the point it would go into low battery mode. At this point if moving enough it would maintain charge level. Through town inevitably the battery was drained. This was all using an SP style dunno hub to power the iphone using google maps to navigate. Using this with one small backup usb battery if needed in town and the phone charged it would last a full days riding. It was simple to fit and didn’t give any problems.

Is the USB output connector waterprooof?
By

Hi
We would say that the USB Werk is water resistant & not water proof, the connectors are fairly well protected within the housings however persistent heavy rain could eventually have an affect.

Is the voltage/amps high enough to charge a very large Anker Power bank? (20,000mAh)

Basically with it be powerful enough with a constant voltage to charge up something so large?
Hi there,

As we have never tried to use this with something so large we would have no idea if this would charge or not I'm afraid.

Thanks.
Can It Charge Iphones?

Your website says the E week can't charge iPhones. Can the USB werk?
Hi,

As the output is regulated at a fixed amp rating on the USB Werk it is indeed suitable for use with IPhones.

Thanks.
Is It Possible To Plug A Ewerk Usb Charging Device Into My Schmidt Edelux Head Light
By
12 Mar 2017
Hi,

the charging device will need to be wired directly into the dynamo as the rear output from the front light will not be sufficient to charge it. Depending on your dynamo you should be able to wire the light and charging device directly into the hub using piggy-back connectors.

Thanks.
Should I Disconect My Usb Werk When Not In Use?
By
03 Dec 2015
Hi,

We would recommend if possible disconnecting the USB Werk from the hub when not in use as it will still provide extra drag to the rolling of the hub. It is however completely up to you if you remove it completely from the bike, this would take longer for removal and re-instalment but would mean that you didn't have an electrical device and wiring sat on your frame exposed to the elements when its not even being used.

Thanks.
