PWR 

Introducing the new Knog PWR range of products.
PWR is an ecosystem of bike and outdoor products designed to share their battery. But, that battery also works as a power bank to charge your devices.
PWR products have the PWR Bank as their battery. You can choose the simple “charger” bike lights which have an integrated power bank, or you can upgrade to the modular system which have interchangeable lightheads and PWR Banks. Either way, now you can use your bike light to charge your phone, watch, Garmin, Christmas mitten warmers...whatever device you like.
