It started as a relief to my range anxiety
As a rider who pushes my board to the limits, I didn't like having to stop and charge every 4 miles or every 7 miles with the Boosted Extended. After hundreds of hours of research and testing, the Booster Box and Booster Box XL is the result. It triples your range in Pro Mode, can charge your cell phone, remote, GoPro, gimbal, Shred Lights via its two usb ports. The Booster Box also packs plenty of power to push bigger wheels for long rides with our custom pulleys for those who commute on rough streets and large distances.
