Just ordered my new bike

The buffer battery in the luxos u is relatively small and if you are slogging up a hill or have a large load on so are going slow it can be depleted fairly quickly. This means that whatever you are charging will stop charging. This can be particularly problematic with mobile phones because the first thing they tend to do is turn the screen on to tell you they are not charging. This can end up wasting more battery power than you are generating. A slightly bigger online buffer battery can help stop that from happening.

The luxos u is great, I got one when they first came out and have 0 problems. If you are price concious rose bikes do them cheaper but you will not then get the excellent install job that thorn are bound to do for you.

Sam any chance you can post pic's of that dynamo set up from the hub to the charger ,i'm a geek i need to see a set up sorry but i know your god with a cmera.
cheers,
anto,

Sorry Anto, I'm currently travelling O/S and away from my bike and my photos. I'll be back in early November and plan to update Atilla's gallery.

I will second what gover_1 said about the Luxos U battery, and also point out that these devices can only be sustainably charged if the lights are switched off, freeing up the current from the hub. I like to leave my lights on during the day when cycling around town, so I want a battery that will cover that off. It's not so critical on a tour out in the countryside, but it's then that you're in the saddle for longer periods. I also have multiple devices.

I bought a PowerMonkey Extreme, and am playing with mounting options at the moment, both for the battery and for the solar panel. My hope is that I can keep both an iPhone and GPS going for 8+ hours by starting out with a fully charged PM. I may be kidding myself...

Whatever dynamo light you go for you won't regret it. I don't ride a huge amount in the dark but just not having to think about if you've got your lights/batteries charged means you can have an extra pint and still see on the way home
I had the older version of yours on my Raven an I have a Schmidt on my Nomad and they both do a fantastic job.

Happy travels on your new bike

Exactly. My theory is that dynamos are more valuable the less you use them. If you ride every night, you'll have a regular routine to keep charged batteries at hand. If you just get caught in the dark on the rare unexpected occasion, a dynamo is your friend!

I have a few flashlights about that are dynamo powered: one has a crank, the other you shake. They don't get used much, but they are always ready!

I use the PM Extreme and carry an 2nd battery pack - Anker 2nd Gen 12000 one on charge / one in use. Not had any issues running my Galaxy Tab with GPS on, and keeps the phone charged as well.
