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. 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.
