Anker Zolo A110E — 20,000mAh. Slim. Built-In. Ready to Go.

For those who can’t afford to run out of battery — travellers, field workers, heavy smartphone users, or students with back-to-back days away from a socket — the Anker Zolo A110E is the answer. A massive 20,000mAh capacity, 22.5W fast charging, built-in cable, carry strap, and ActiveShield 3.0 protection, all in a surprisingly slim package. This is the daily carry power bank for serious battery needs.

🔋 20,000mAh — Four Phones. One Power Bank.

With 20,000mAh (74Wh) of stored energy, the A110E delivers approximately 4 full charges to most smartphones — enough for a full weekend trip, a field day without sockets, or keeping multiple people powered during a long haul. Despite the massive capacity, the body measures just 14.07 × 7.17 × 2.77 cm and weighs 392g — genuinely slim for a 20K unit.

⚡ 22.5W Fast Charging — Serious Speed

The 22.5W USB-C output charges compatible smartphones to 50% in around 30 minutes. Whether you’re on an iPhone, Samsung Galaxy, or any modern USB-C device — the A110E pushes power in at the maximum rate your device supports. No compromises, no throttling.

🔌 Built-In Bidirectional USB-C Cable — Input AND Output

The integrated USB-C cable is bidirectional — meaning it charges your devices AND recharges the power bank itself, eliminating the need for any external cables entirely. Tested to survive over 10,000 bends, this cable is designed for daily rough handling. Combine it with the USB-C port and USB-A port for simultaneous 3-device charging.

👜 Built-In Carry Strap

The A110E features an integrated wrist carry strap — a small but genuinely useful design detail. Slip it on your wrist, hang it from your bag, or loop it through a backpack strap. It keeps the power bank accessible during commutes without needing a pocket or dedicated pouch.

🌡️ ActiveShield 3.0 — Anker’s Best Safety System

ActiveShield 3.0 performs over 6 million temperature checks per day — constantly monitoring and adjusting charging parameters to prevent overheating. This is Anker’s most advanced protection system, providing peace of mind for both the power bank and connected devices, even during extended sessions.

🔄 Pass-Through + Trickle Charging Mode

Recharge the A110E while simultaneously charging a device via pass-through technology. The dedicated Trickle-Charging Mode delivers a safe, regulated low-power stream for devices like wireless earbuds, smartwatches, and fitness bands that are sensitive to standard charging currents.
