Upgrade to next-gen portable Power Delivery. We designed our Power Pack Pro+ with a simple motto in mind: “Do more with less.” With new-and-improved components, the 20,000mAh XL-capacity battery lasts 45% longer and provides up to 70 hours of extra life for your devices on the go. The re-engineered USB-C Power Delivery port is now PPS-compatible and powerful enough to charge the latest iPhone, iPad, and Android devices at super-fast speeds – and the 35W maximum output transforms this power bank into a portable full-speed charger for MacBook Air and other notebook laptops. This is laptop-level power in an ultra-slim, ultra-portable design that is smaller than most other phone-charging power banks.
