the charger does not give a full charge the little green light goes to flashing red (its charging) and should stop after a reasonable time...ie when charged but it only charged for a small time so I have had to keep taking plug out and pushing back in again. I have had the light for 3 years and apart from the charging prob has been good. As the nano shot plus has top reviews and it is half price here certinaly worth getting with a different type of charger...ie usb cable....so here's hopingYou didn't learn from the failure of the last charger?
I love Edinburgh bike co op but they don't sell any decent lights at the moment. Cateye haven't been great for a few years now. As http://www.edinburghbicycle.com/products/cateye-nano-shot-plus-el-625rc says: " This light can be used on road but it does not meet RVLR requirements."
