Anker Power Bank (20K, 87W, Built-in USB-C Cable) — Black
The Anker Power Bank (20K, 87W) is a high-capacity travel charger built for people who need real laptop-charging power on the go, not just a phone top-up. Its 20,000mAh battery is large enough for multiple smartphone recharges, tablet use, or keeping a lightweight laptop running through a travel day. 87W total output can be split across up to three devices simultaneously, with a single device able to draw up to 65W — enough to bring a 14″ MacBook Pro to 50% in under 40 minutes. The built-in USB-C cable delivers the same fast charging without needing a separate cord, pushing an iPhone 15 Pro to 58% or a MacBook Air to 52% in just 30 minutes, and is rated to survive over 10,000 bends of daily use. The power bank itself recharges to full in about 1.5 hours with a 65W charger, and it’s approved for airline travel.
