Switched Basic: Lamp- inline switch for lamp/USB-hub connection – This system now allows you to turn off the lamp and turn on the Sinwave USB charger. This gives you the ability to charge your head light during the day or perhaps your phone if need be.
Top Cap Switch: Lamp – top cap switch for lamp/USB- hub connection – Similar to the bar switch the top cap switch allows for easy transfer between the lamp and the USB. The top cap is super convenient and is a nice alternative to the bar switch if you need more space.
Bar Switch: Lamp- bar switch for lamp/USB- hub connection – This system allows you to have easy access to to switch between the lamp and USB. You can put this directly next to your brake and shifters.
Kerry has recently developed a system where the lamp stays on and you can continue to run your Etrex/GPS at the same time. I have not had any experience with this system, and will likely continue to use batteries to power my Etrex. But if this interests you, he can certainly help you out.The main difference in these systems is where the switch is placed, which is nice to customize for your convenience. With the inline switch, top cap switch, or bar switch, you have an option to tell it to go to the light, or the option to tell the power to go to the USB port. Most recently, I used the bar switch, which proved to be super convenient. After a night of riding, I would take my Diablo Exposure light off my helmet and plug it into the Sinewave Cycles Revolution Charger, which was basically ready to go in my Bedrock Tapeats. With the quick flip of the switch, I would be charging the Diablo Exposure all day, or until it was fully charged. On the Tour Divide I could charge the Diablo Exposure in roughly 2/3rd of a day, especially with the fast road and ample sunlight there is in the middle of June. For the Arizona Trail, it took nearly all day for it to charge on slower singletrack. Something I was a bit worried about going into the race, and something I realized could be a problem during the race. I did end up turning off my headlight on some simple road sections to save the battery, but those were few and far between on the AZT. Luckily, my head lamp only ran out once, towards dusk one morning. While the bar switch is so convenient, I was a bit worried about how it would fair if I took a tumble, luckily that never happened. Cache Batteries On the Tour Divide, I did start by plugging in my cache battery into the Sinewave so I could charge something at all times of the day including my helmet light, iPhone, or iPod. But like many have experienced, the Micro USB port on my cache battery broke after it got jared around, rendering the battery useless weight. If you want to use a cache battery, be sure to secure it properly and perhaps reinforce the micro USB cable when installed into the cache port. I decided to carry a cache battery again on the AZT, but this time just for emergencies. Going slow speeds would not allow the hub to charge the battery, and I was better off just using the Sinewave port for the Diablo Exposure, and iPhone/iPod when needed. Overall, the system is pretty darn bomber and you can tell Kerry pays attention to the detail in making each wire and port waterproof and insuring that the system continues to work in all conditions. During the setup process, I did have a difficult time mounting the light to my specific needs, but that was a problem on my end, as Kerry provides plenty of mounting options, even zip ties to help you connect the system to your bike. The Bikepacker Pro may be a bit confusing at first, but once you get your hands on it, you will notice how easy the system really is. Please let me know if you have any specific questions, I have used this system for a solid year now, and would love to help out if I can.
