I've put on about 300+ night-commuting miles with this lighting/charging unit, and I feel I can finally give it a fair review.

Some general info:
I measured the voltage output of the dynamo: it varies from a few Volts, to over 10 or even 15 Volts when you are going faster. I assume there is circuitry inside of the lamp unit that stabilizes the voltage to 5V, which is then output through USB.

The lamp unit has a built-in rechargable battery that gets recharged as you pedal, but it seems not to be a very good system (read below).

Now the review...
The good:
1. This device does work to charge my iPhone 3G. I've used it about 4 times for that purpose so far. As soon as you connect it via USB, the iPhone charging starts -- even when you're not pedaling (it charges the iPhone from the built-in rechargeable battery).

2. The light is of decent brightness. It works well to make you visible to cars on streets that have some street lights on them. If you want to light a very dark road ahead of you, you may want to add another light of similar brightness.

The bad:
1. The built in rechargable battery seems to be garbage (either the battery or the charging circuitry). The other night I rode for almost 2 hours (about 30 miles) with the dynamo engaged and charging the battery. The next day, as a test, I was running the light without the dynamo engaged. The light lasted for only about 20 minutes, and got very dim afterwards. The conclusion is that this light will work great while you are pedaling with the dynamo engaged against the bicycle tire. Don't count on it when you want to disengage the dynamo. Mind you, I was running the light while I was charging the battery, so a lot of energy went into powering the light...

I was very apprehensive about buying this because there were not only no reviews on Amazon, there was nothing about this anywhere on the web that I could find, and reviews of other products from this company weren't stellar to say the least. But I wanted to be able to use my smart phone on long bike rides with the screen on the whole time and this product is apparently completely unique in providing a dynamo powered usb port.

I'm not the handiest guy, but not a complete klutz. Installing the dynamo was a bit of a pain on my bike. I'm not sure if it is the design of the dynamo/mounting bracket or my bike (or me), as it's been 30 years since the last time I installed one of these. I ended up installing it so that it rolls on the tire instead of on the metal rim. Works fine, but it's not the "right" way to do it.

I don't have an iPhone, but my LG Optimus fits very securely in the iPhone holder and no problem accessing the USB port on the LG through the iPhone port slot on the bottom. Based on the shape, I suspect it's made for an iPhone 3 / 3g / 3GS. It's a fairly hard rubber and curves around the front of the phone just a bit. Looks like the iPhone 4 will fit in it, but might be tricky getting it in and out. No cutout for camera. You might find you will get better mileage with a bike mount specifically designed for your phone from a better known company, but it's worth trying out first.

I haven't ridden with it at night, but the light is certainly bright enough to make you visible. I doubt it is going to be much of a headlight with its single LED.

The whole point of this for me was the USB charging port.

Bought devise and installed it right away. I have a Droid2 so I am not usiing the cradle and there are much better cradles out on the market for I-Phones. I would suggest one that is weather proof. The head lamp is ok for a low grade headlamp. The charging system works fantastic. The dynomo generator has two many plastic parts and broke within 2 miles of use. I have opted to use an in-hub dynomo instead of replacing the one it came with. In-hub is the way to go. No noticable drag and no noise. For the price the headlamp charging system is fantactic. Now I can keep the spare battery in my backpack and not have to worry about my battery life.

I ride mainly during the day.Average distance is 6 miles per trip. Upwards to 25 miles. I stream Pandora and use Mapmyride app for GPS and mapping.

The concept is great, but if you buy this product, be prepared to have a more sturdy replacement dynamo on order and in the mail for when this plastic dynamo gets grated on the tire like cheese on a cheese grater. Again, concept does work. Powers my iPhone, rear 6 Volt light, and charges the headlight as well, but the dynamo was destroyed just riding around the lake.

as possible back up dynamo's.

Design and Idea is very good. Equipment is CHEAP. The Generator is made of plastic and about 1 mile down the road it melted at the end. Design makes sense and it was working, up until it MELTED. Sending back, if I get a return and it works, I will upgrade my review.
