Quickly charge a USB-C compatible device, such as a laptop, with the Tether Tools ONsite USB-C Battery Pack. The battery's 25,600mAh power output can provide 1.3 recharges of a 13' MacBook Pro and other laptops as well as two recharges on an iPad Pro, and up to five recharges on smartphones.

When used with Tether Tools ONsite Relay Camera Power System and coupler (sold separately), the 150W battery will power a camera between 10-27 times as long as a normal battery. This is key when shooting tethered, as USB-C powering and tethering from the same port is not recommended. For tethered shoots, you can power your computer and camera from one single battery. When not tethering, this battery can charge your camera via its USB-C port.

Designed for mobility, this power bank is TSA/Airline-Compliant, and its sleek design slides into any backpack, camera, or computer bag. The battery takes approximately three hours from empty to charge and delivers pass-through charging so you can power your tech, while the battery is recharging.
