Ultra-compact

20,000 mAh, barely bigger than your phone.

Among the most compact 20K mAh portable chargers on the market — at 12.9 oz and under six inches long, it slips into a jacket pocket or side bag without the brick-in-a-bag feeling. A built-in lanyard loop lets you clip it to a backpack, so fast charging rides along wherever you go.

Fast charge any device

Two USB-C ports, 65W of pure power.

Enough juice to fast-charge a laptop through one port while topping off a phone on the other. Power Delivery handles smartphones, tablets, headphones, wearables, speakers, and laptops up to 65W — so the devices that run your day all run from one brick.

Sustainability

90% recycled plastic. -9.1 lbs of CO2.

Housed in 90% post-consumer recycled plastic, packaged in plastic-free post-consumer scrap paper, and backed by free e-waste recycling for your old tech. An average -9.1 lbs of CO2 saved compared to conventional portable chargers.

    I’m a college student, and I use this nearly everyday as a second charge to my laptop. It’s light weight enough while also keeping it’s durability. Love this thing!

    Power for a Video Camera

    I attached the charger to the bottom of my Steadicam (with Velcro), where it also serves as a balancing weight, and use it to power an Insta360 camera as a second camera. It allows a remarkable versatility!
