Lights and a Bluetooth speaker use a universal, swappable battery

Australian brand Knog is using Kickstarter to launch its pwr range of products that use a universal power source.

The pwr range comprises bike lights, a headtorch, a lantern and a Bluetooth speaker, all of them using the same “pwr bank” as their battery.

“It’s such an obvious idea really,” said Knog’s CEO Hugo Davidson. “You don’t use all these products at the same time so why not save on batteries? If you do use these all at the same time, then you can have as many batteries as you like, giving you longer runtime. It’s win-win.”

Beyond powering these items, the pwr bank has a USB charging port that you can use to power your phone, for example, or a Garmin while you ride.

The 800 lumen pwr 800 bike light is said to have an elliptical beam and a low-light mode where the ring of the lighthead glows, and the pwr 300 bike light (above) can convert into a headtorch if you buy a headstrap for it.

The pwr headtorch has spot and glow modes while the outdoor pwr speaker (above) is water resistant and works via Bluetooth.

The pwr bank battery is 3200mAh and is said to have enough juice to power the speaker for about six hours.

You need to pledge at least AU$65 (about £41) to be inline for the 300 lumen pwr 300 with the pwr bank battery. Prices for other elements of the system go up from there.

You need to pledge AU$379 (about £312) for the whole system (you only pay if the project meets its AU$75,000 target – about £61,649 and usual Kickstarter rules apply). 

One potential sticking point is that delivery is not expected until June 2017.
