The ONsite USB-C 150W PD 25,600 mAh Battery Pack offers 150W USB-C Power Delivery (PD) to quickly charge a USB-C laptop, keeping you working despite the heavy power demands of your computer and other gear.

With the highest quality battery cells, you can rely on the ONsite 150W battery’s 25,600 mAh power output for 1.3 recharges of a MacBook Pro 13in and other laptops, as well as 2 recharges on an iPad Pro and 5 recharges on phones. So, whether you’re working or relaxing, you’ll always have power on location or on vacation.

The ONsite 150W Battery Pack can also charge three devices simultaneously, with 2X USB-C ports and 1X USB-A port to power up your laptop, tablet and phone.

Power Photo & Video Cameras

When used with Tether Tools ONsite Relay Camera Power System and coupler, 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.

Power USB-C Lighting

Many strobe and LED lights are USB-C power enabled. The 150W provides an all-day power source for your lights, which is ideal especially when shooting on location. Mount the battery pack with the Strapmoore directly to your light stand.

Designed for mobility, the ONSite USB-C 150W PD battery 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.

Let running out of power be a thing of the past with the ONsite 150W Battery Pack.
