Want to keep your phone or portable battery bank topped off during a long day or over the course of a multi-day adventure? This little workhorse is just the thing.<\/p>\n
Let me tell you why we love this charger.<\/p>\n
The Sinewave Revolution\u00a0 will be the first and last dynamo powered USB charger you’ll ever buy. Why? Because it just won’t break.<\/p>\n
From the owner of WBK, “I picked this exact model in 2013 to keep my phone charged on a two-week Pacific Coast tour. Back then Sinewave was a\u00a0 startup in Massachusetts, USA, making a weird little dynamo powered USB charger device that made a splash in the touring world. Even then, I wasn’t sure it was worth the price when I placed the order. After thirteen years,\u00a0 three bicycles,\u00a0 several tours in Japan, Baja Mexico, and the United States, covering over 6,000 miles… it still works great. This weather proof charger has endured rain, snow, and desert heat, delivering trouble free independence from the grid.<\/p>\n
I’m delighted to confidently recommend the Revolution here with the assurance that it will most likely outlast me and you until nuclear-powered button batteries render it obsolete.”<\/p>\n
