Does what it says on the tin

Haven't had this product long but fixed it to the outside of the garage door , had a few down pours and it has survived , so no reason to think it won't last were it is , charges my 955i as have a datatool attached and it's a constant drain but the Oxford solariser more than makes up for the drain , I would recommend this product

Just the job when using to charge my bike's battery in the shed away from an electrical socket? It is only a trickle mind! Especially in the British climate!

Keeps the battery topped up.

Not had a battery go flat since using this to keep them topped up. I have adapted one of the battery leads to accept a more standard connector so I can plug it into an Optimate type connection as fitted to all our vehicles - shame such a connector doesn't come as standard (took 10 minutes with a soldering iron to do the job.)

So far so good installed in garage window, proof of the pudding though will be next winter.

So far so good

Compact and easy to install and connect to car battery via crocodile clips and option to add lead hardwired to motorcycle battery. Pushes out 17V on cloudy days and 24 in direct sunshine. Will need more time to see if it does what it's supposed to ...

Seems to do what it says on the tin

So far so good, seems to be doing the job. I bought this solar charger to keep the battery topped up over Winter when I don't ride it that often. The bike is kept outside, so I use an Oxford cover to offer a bit of protection against the elements. The optimizer fits nicely inside the pocket provided for this in the cover, and I've permanently connected it to the battery using the lead and socket provided. This makes it real easy to disconnect when removing the cover. Seems to be well made and so far appears to be doing the job OK with no signs of the battery running down. It's not just the inconvenience of having a flat battery, I've also found that if you allow a battery to remain flat for too long, it's likely to give up the ghost sooner rather than later. So hopefully this will also save me money the the long run. Time will tell. But for now I'm a happy bunny.

Didn't work for me

The unit doesn't appear to work in winter, when I need it most. My bike's battery was fully charged, connected the Optimiser and after just under a month the battery didn't have enough oomph to start it yesterday morning. The blue charging light was flashing during daylight hours so I can only assume it was doing its job but not effectively enough.

It works when has lots of sunshine

I bought this charger so that it keeps the battery in top shape when I do not run the bike. I have an alarm and a GPS tracker that they draw current from the battery continuously. The charger is easy to install and the cable connection are easy to use. The output of the charger however depends a lot on the sunshine. Here in the UK that is a big problem. I guess that during the summer months it will be OK but during the winter it has failed to keep the battery charged. During a week the battery has discharge below an acceptable level. Another downside is that the solar panel is not classified as waterproof. That means that you have to disconnect it when it rains. I didn't and there was no damage done so far but I do not know how long it will last. So for the winter months I have a mains powered charger. It is a good product but the details let it down.

Usual Oxford Quality

Delivery was up to usual reliable standard I expect from Sportsbikeshop. The product was well packaged and seems robust. Easy to follow instructions and easy to install. I used the battery leads and left the connection socket just poking out beneath the seat of my Ninja 650. It is very easy then to connect and disconnect. Will it keep the battery topped up over winter? Only time will tell. I do note that the charging light is flashing even on dull winter days so looks hopeful.

Seems to do what it says and here's me sceptical

Thought that it looked a bit non starter but was wrong, as it did what it says and kept my battery on the bmw charged while I was away for three weeks !! Easy fit and came with all the connections that you could possibly need, great stuff from Oxford as per usual.

I am presently impressed

Was very sceptical of products effectiveness, but I have to say I am presently impressed. I do feel the lead length between solariser & my bike could have done with being longer but I guess I could invest in a extension cable Oxford produce. As for quality of of product I guess time will tell. So far I recommend this as a alternative to a mains powered trickle charger.

Great bit of kit

BMW R1200RT was getting a bit difficult to start. No power in the garage so got the solariser. Problem solved. Recommend this product.

Handy to have but realistically does little

Had high hopes for this solar charger but I've had little benefit from using it. Max output is a real world measured 0.11A as stated on the box, a mains Optimate trickle charger maintains a battery at 0.23A charge rate. More realistically you'll be charging at around 70-90mA. But it's free power and portable too, and if you buy a Tamiya connector off eBay and swap the red and black wires over you can then plug it straight into your Optimate charge lead if you have one fitted to your bike. Surprised this Oxford charger doesn't come with that connector as it comes with crocodile clips, cigarette adaptor etc but no optimate connector. So yes this will keep a battery topped up if you have an alarm or tracker fitted but it won't charge up a battery unless you leave it connected for a week or more. Worth having just for it being solar power as a quick and easy backup.

I have been nicely charged

A great little charger; its my second actually as I unfortunately let the first one fall off the garage roof!

Simple and effective

Great and surprisingly compact charger, the LED is a useful touch that lets you know its getting enough light to do its job. Nicely designed electrical connectors that are unobtrusive and neat. Can't comment on the long term durability yet but first impressions are good.

Great charging system

Just a spot on idea combined with the Oxford Stormforce cover to ensure the battery is maintained all year round.

So far so good

Keeps my battery topped up on my Suzuki GSX750 My lock up is away from the house with no power and this piece of kit was recommended to me. I have it fixed to my garage roof with the cable running through to the bike. Its been rained on and is open to the elements so don't know how long it will last but so far so good.
