I have the big battery version with the USB Loader cable, so I can use it as a standard USB power pack and charge from AC if needed. I put it in a PVC tube the size of an old school bike pump and it clips into pump clips on my downtube. I disconnect it and take it into the tent at night. The only slight downside is it looks like a bomb to Airport security, what with it being slightly home made, having a push button and flashing lights. Usually gives them a laugh when I explain it though.
If I was with TSA, I do not think anyone could talk me into believing that a PVC pipe full of electronics is that harmless.
I have had good luck with my Sinewave Revolution, but when I saw the output claimed by the Cycle2Charge, I thought about ordering one. That is until I saw a 30 Euro shipping charge to USA, then I rapidly lost interest. If my Sinewave died, I would probably give the Cycle2charge a try as the price with shipping is competitive with another Sinewave, but I do not need another charger that much. And the Sinewave waterproofing is exceptional, I have no clue how well waterproofed the Cycle2charge is.

The Cycle2charge website claims about 4.8 watts at 20km/hour, that is pretty close to the Forumslader output.
