Overall Product Rating 5 / 5
Amazing device!

5 / 5
I recommend this product
ConsWhen running at night slight loss of power to the light but still plenty enough to see by
ProsClean simple design, does everything you would want it to!
After an a disappointing experience with a similar product by another brand that lasted 5 days I was recommended this by SJS. Its been faultless and I cant recommend it more highly! I recently used it on the London-Edinburgh-London 1400km Audax, it kept my iphone running RWGPS and my Garmin 500 charged for the entire ride. I had no issues running them directly off the device with no need for a cache battery. It worked in all weather conditions and was left out in the rain at night on several occasions and worked fine the next day. The build quality is very good and it can rotate on the mount which can be useful for moving it for different length USB cables or just ease of access.

I recommend this product
ConsA little pricey, but worth it IMO
ProsEasy to fit, small, dependable
Only taken this on a brief test ride so far but the results are great. Super easy to fit and the unit is small enough to tuck in a frame bag, or be stealthily mounted on the outside of your frame. Will be an essential piece of my touring kit going forward.

bottle dynamo ok?
29 Jul 2018
Can I use this with a bottle dynamo? If so, which one would you recommend?
You can use this with a bottle dynamo, but we really do not think the power output would generate enough to actually transfer a power into a device and therefore would not recommend it.

Can I use this with Exposure Revo Dynamo?
08 Jul 2018
Would this be needed to if I were to use an exposure revo dynamo light? Many thanks
Yes this would be suitable.

What comes in the box?

What parts are supplied with this product?

You get the charging unit, the hard wired cable coming from it and a large zip tie for mounting. You will need to supply the appropriate connectors for your hub.

Revolution vs Reactor
30 Aug 2017
Hi - is it just the form factor that is different when comparing the revolution to the reactor? I don't particularly want to drill the fork on my bike, as it will invalidate the warranty and if there is no added benefit other than the size, I wouldn't see the need of spending an additional £100


The differences are just in the fitting, internally they both are the same. You should not need to drill your actual fork to fit the reactor though.
