The Anker Zolo Power Bank (20,000 mAh, 22.5 W) is the ultimate grab-and-go companion, featuring a rugged, tangle-free built-in USB-C cable that’s permanently attached and tested for over 10,000 bends, delivering full-speed 22.5 W PD/QC charging straight from your pocket. With its 20,000 mAh high-density cells, it can fully recharge an iPhone 16 Pro Max nearly four times or a Galaxy S25 Ultra three times, while a bright digital display shows exact battery percentage (no more guessing with LED dots).
Thanks to one extra USB-C port and one USB-A port, you can charge up to three devices at once (phone at 22.5 W, tablet at 18 W, earbuds at 5 W), and smart power allocation ensures everyone gets the fastest possible speed. Double-tap the button to activate low-current trickle mode for safely topping up smartwatches and wireless earbuds.
Key Features
Built-in USB-C Cable That Never Gets Lost

20,000 mAh Capacity with 22.5 W Fast Output
High-density cells provide enough power to fully charge an iPhone 16 Pro Max almost four times or a Galaxy S25 Ultra three times, while pushing up to 22.5 W PD/QC to reach 50–60 % on most phones in just 30–35 minutes.
Precise Digital Percentage Display
A bright circular LED screen shows the exact remaining battery level (e.g., 73 %) instead of vague dots, letting you know exactly how many more charges you have left before heading out.
Three-Device Charging at Once
Use the built-in cable, extra USB-C port, and USB-A port simultaneously to charge a phone at 22.5 W, a tablet at 18 W, and earbuds at 5 W with intelligent power sharing that keeps speeds optimal.

FAQs
How long does it take to fully recharge the power bank itself?
It recharges at up to 18 W via the USB-C port or built-in cable, taking about 5–6 hours from 0–100% with a standard 20 W phone charger. Kenyan users recommend using your original Samsung or Apple adapter for best results, as slower 5 W chargers can double the time.
Can it fast-charge my iPhone 16 or Galaxy S25 at full speed?
Yes—the 22.5 W PD/QC output matches the max speeds for both (27 W on iPhone with PPS, 25 W on Galaxy). Most owners report 50% charge in 30–35 minutes, though actual times vary by case and temperature.
Can I charge three devices at the same time without much slowdown?
Yes, but total output caps at 15–18 W across the built-in cable, USB-C, and USB-A ports. A phone gets 10–12 W, tablet 5–7 W, and earbuds 3–5 W—still practical for mixed use like iPhone + AirPods + smartwatch.
