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.

Can I use with an Alpkit Juice hub dynamo?
26 Sep 2019
What, if any, connectors would I need, or would bare wires be acceptable? Finally, where do the wires run in the stem mounted Reactor if, as previously stated, there is no need to drill carbon forks: it was the Reactor that really caught my eye.
These fit bare wire onto that hub, same as Shimano or SP or Jtek.

The Reactor wire simply goes into the bottom of the fork and up the steerer tube.

how to connect the stripped wire end to dynamo hub SON 28 ?

Add a Garmin mount to the Revolution?
18 Jul 2019
Is it possible for you to customise the Revolution with a permanent mount so that it fits on the underside of the double mount for a Garmin gpx? The advantages are an easier installation by twisting it 90 degs to lock it as opposed to using a cable tie. Also the device will benefit protection from the rain as it positioned under the Garmin device. Thirdly is it a far better space saving area than cable tying it to the stem. I lead charity cycle tours London 2 Paris many times a year, keeping my Garmin and phone is paramount. I am sure for many, it is a winning idea.
We have never tried! We like the flexibility of simple cable tying the box wherever it fits. On our Thorn touring bikes and many similar we rarely see anything mounted in the small space under the stem so this is an obvious and ideal place to pop it. The device is fully waterproof so no need to worry about rain protection.

Son delux 12 Hub, Exposure light and Revolution
25 Jun 2019
Hello, my bike has a son deluxe 12 hub wired to rear of Exposure Revo front light, which then feeds rear red eye. Can I fit Revolution to charge battery power bank to then charge garmin and iphone? If yes, can it have connectors to wire between existing cable and revo. As in permanently wired ? If not, is it possible to come with connectors that the electrical feed to light is removed from light and plugged into Revolution indaylight? thanks Alan

to light can be plugged into Revolution
Hi there,

We think your best option would be to use piggyback connectors at the Dynamo, which will allow you to wire in the Revolution at the dynamo and have constant power going to it.

However, as we have never tried this here we cannot guarantee that this will work 100% I'm afraid.

SP PD8 Dynamo
23 May 2019
Thanks for your earlier reply.

The SP dynamo hub came with the bike so there are no connectors with it. Could you please recommend some connectors?

Thanks again.
Hi there,

The best connectors to use would be part #32495.

SP PD8 Dynamo
23 May 2019
Can I use the Sinewave Revolution with an SP PD8 Dynamo and if so how would I connect them please? Many thanks.
Hi there,

You should be able to do this without an issue. The Sinewave comes with bare cable allowing you to insert this into the connectors that should have come with the hub.

Can I use the sinewave to charge my Iphone 8
13 May 2019
Can I use the Sinewave with a Son Edelux11 & a Sondelux dynamo? What connectors would I also need to run the light and USB at the same time? Also would this be able to charge an Iphone 8?
The deluxe Is only suitable for lighting, its a paired down version of the 28 so not really suitable for both / or charging.

Connectors - SJS Cycles part number : 28876

Son dynamo, Revo light AND other devices
10 May 2019
How do you connect the son dynamo to the Sinewave so that you can switch between Revo lights and/or charging other devices? Do you have to crimp & run two cables from the dynamo or is there a more neat solution?
We would use SJS Cycles part number : 28876, connecting both the lighting and charging devices at the same time.

Thanks - 10/05/19
Can this be wired into SON coaxial cable connector?
05 May 2019 that I could connect to SON Y-junction box rather than piggyback connectors at hub
Yes, this would work.

Thanks - 07/05/19
will this charge a samsung s7 phone using son dynano
06 Dec 2018
Yes, this should have no problem!

Thanks - 07/12/18
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?
28 Feb 2018
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.
