Anker Nano Power Bank (20,000mAh, 30W with Built-In USB-C Cable)

Description

The Anker Nano Power Bank (20,000mAh, 30W with Built-In USB-C Cable)—model A1387—is a high-capacity, highly portable portable charger designed to power smartphones, tablets, and even smaller laptops on the go without the clutter of extra wires.

Full details regarding its specifications, design, and performance features include:

1. Capacity & Core Performance

• Battery Capacity: 20,000mAh (74Wh total energy using dual cells in series). This is enough to charge a standard smartphone roughly 3 to 4 times or a tablet multiple times.

• Max Power Output: Up to 30W Max, which is powerful enough to fast-charge modern iPhones (e.g., iPhone 15/16 series), Samsung Galaxy devices (supporting PPS fast charging), and iPads at optimal speeds.

• Bi-Directional 30W Fast Recharging: The power bank itself can be fully recharged at 30W speed, meaning you can top it back up rapidly using a high-output wall charger.

2. Ports & Connectivity

The device features a versatile 3-port configuration, allowing you to charge up to multiple devices simultaneously:

• Built-In USB-C Cable: An integrated, durable, angled USB-C cable that acts as both an output and a high-speed input channel. When not in use, it neatly tucks away or doubles as a handy carrying strap.

• USB-C Port: A separate standalone USB-C port supporting 30W max input/output.

• USB-A Port: A legacy port offering up to 22.5W Max output for older devices or accessories.

• Total Combined Output: Max 24W total output when multiple ports are utilized at the same time.

3. Smart Digital Display

• Features an intelligent color LCD screen that provides real-time updates.

• Clearly displays the remaining battery percentage, active charging status, full recharge time estimates, and indicators when specific modes are turned on.

4. Special Features

• Trickle-Charging Mode: Designed for low-power accessories like wireless earbuds, smartwatches, or fitness bands.

  • How to use: Can be activated by double-pressing the power button (particularly when using the USB-A port) to supply a safe, low-current charge without cutting out automatically.

• Compact Ergonomics: Despite packing a heavy-duty 20,000mAh cell capacity, it is engineered with a slim, travel-friendly profile (roughly measuring 6.5 × 3.0 × 0.8 inches) that easily slips into a backpack, purse, or briefcase.
