Smartphone and Nimble power bank charging on a rocky surface.

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.
