It has been several weeks, and I am very happy with my spinpower. First of all, it really does make my phone battery last for the entire ride. So far, I have tried it on 2, 4, 6, and 8-hour rides with stops. I use my phone very actively. I run a cycle app, I recently used a gps feature to explore a new bike path, and I listen to books almost all the time. What a liberating experience not to think about turning the screen on and off. My phone's battery now last for the entire time. After an 8-hour ride, and some very active use, the phone battery went down maybe 4-5%, which was really great. Also, one surprising result - it takes me a fraction of the time to get ready to go out now because I do not have to spend time for charging the phone battery. In fact, I do not even worry about that anymore.
Overall, as I said in the title, I am very pleasantly surprised. I bought the device without much expectations, but got really good usage out of it. I highly recommend it to other cyclists, especially those going on bicycling tours.
Problem is, I found myself on the road after dark with my phone out of power. I have used small portable solar chargers with built-in batteries, but they give an emergency charge at best and are more suited to the older style phone that use far less power (and will run for a week on a single charge). What I needed was the ability to charge my phone ANYWHERE at ANYTIME and keep it going all day long. The Bike2Power SpinPOWER S1 kit provides this at a cost that won't break the bank. First off, there are several issues that one needs to consider when using power from any kind of source that is off-grid. No matter if it is solar, dynamo, or backup battery, the watts and mah (milli-amp hours) need to add up. I'll focus on the dynohub since this is what I'm reviewing, but keep this in mind for ANY off-grid charging or power source and ask someone who knows if you don't.
The dynohub produces power just like other generators; it consists of a wire coil and magnets which spin from the bicycle wheel motion. As you might imagine, bicycle wheels spin at widely varying rates, which causes the power to fluctuate as well.Read more ›
We Purchased the spin power S1 for our next trip. I was not too hard to install and it was able to power our Garman NUVI 370 with no problem. It will also charges up our MP3 player. The cell phone mount also held our Garman NUVI with no extra modifications. We are happy with this purchase and recommend it highly.
