Never worry about a dead laptop battery while working on the go. The Anker Laptop Power Bank 25K (165W) is built to deliver fast, desktop-class charging performance in a compact, travel-friendly package. Packing an enormous 25,000mAh internal cell capacity and pushing up to a massive 100W single-port output, it easily fast-charges MacBook Pros, Dell XPS laptops, iPad Pros, and flagship smartphones. Designed for ultimate convenience, it features a built-in magnetic retractable USB-C cable to simplify your mobile workflow.

165W Massive Total Output & 100W Single-Port Delivery

Power through high-demand tasks anywhere. The power bank features a multi-port power system capable of delivering a combined 165W output across multiple devices simultaneously. The primary USB-C line outputs up to 100W Power Delivery (PD 3.0), allowing you to charge a 16-inch MacBook Pro up to 50% in roughly 30 minutes, ensuring your heavy editing, coding, or gaming laptops stay operational through long remote shifts.

Built-in Retractable USB-C Cable + Secondary Fixed Line

Say goodbye to tangled, messy cables in your bag. The power bank integrates a heavy-duty, retractable USB-C cable that smoothly extends up to 2.3 feet (0.7m) and snaps back safely into place via a magnetic latch when not in use. Tested to endure over 10,000 friction pulls, it works alongside an integrated lanyard-style USB-C cable, ensuring you always have fast-charging lines ready to go without needing extra cords.

Huge 25,000mAh Capacity & Ultra-Fast Self-Recharging

Enjoy multi-day power independence. The massive 25,000mAh (90Wh) internal battery bank can charge an iPhone over 4 times, a Samsung Galaxy S Series device nearly 4 times, or supply a full battery top-up to a 14-inch laptop. When it’s time to recharge the power bank itself, it supports 100W high-speed USB-C input, refilling the entire 25,000mAh battery cell in just around 1.5 hours using a compatible wall charger.

Smart Digital Display & ActiveShield™ 2.0 Temperature Protection

Track your power metrics with absolute precision. A built-in smart color TFT display gives real-time visual feedback on remaining battery percentage, input/output wattage for each port, and estimated full-charge time. To keep your expensive devices safe, Anker’s proprietary ActiveShield™ 2.0 system monitors internal temperatures millions of times per day, dynamically adjusting power levels to prevent overheating, short circuits, and battery degradation.
