This article covers ASUS 5K モニター ProArt PA27JCV.

Overview

The Anker Power Bank packs a 20000mAh capacity into a lightweight body of roughly 345 grams, making it one of the most portable high-capacity options on the market. With two USB-C ports delivering up to 30W each, this power bank can fast-charge smartphones, Nintendo Switch, and even some tablets. Anker’s PowerIQ 3.0 technology intelligently identifies connected devices and delivers the optimal current for safe, efficient charging. A 4-stage LED indicator on the side shows remaining battery level at a glance, while Anker’s MultiProtect safety system guards against overcharging, over-discharging, and short circuits. For the price, this 20000mAh/30W combo hits a sweet spot between capacity and portability.

Connectivity & Compatibility

The power bank features two USB-C ports (each supports both input and output) plus one USB-A port (12W max). The USB-C ports support Power Delivery (PD) and are compatible with iPhone 15 series, iPad Pro, MacBook Air, Nintendo Switch, and many Android phones. The USB-A port works with legacy devices and accessories. Pass-through charging is supported, meaning you can charge the power bank while it simultaneously powers another device. However, when multiple ports are in use, total output is limited to 30W, so charging a laptop and phone at the same time will slow down both.

Product Info

The Anker Power Bank 20000mAh 30W sits in the mid-range tier of the portable-charger market. Released in 2024, it carries a typical retail price of around $49.99 (official store) and comes with an 18-month warranty. The package includes a USB-C & USB-A cable (approximately 0.6m), a quick-start guide, and a manual. It is widely available on and at major electronics retailers.

Best Use Cases

  • Smartphone user: With enough capacity to fully charge a typical smartphone 3–4 times, this is a great travel companion. You can leave the house without worrying about finding an outlet. However, it lacks wireless charging support, so if you rely on MagSafe or Qi, consider another model. - Nintendo Switch owner: The power bank can charge a Switch in handheld mode about 1.5 times. The 30W PD output works even while playing, though it cannot power the Switch dock for TV mode. - Frequent traveler: The 20000mAh capacity (roughly 72Wh) falls under the 100Wh airline limit for carry-on luggage, making it air-travel-friendly. Its light weight and compact size fit easily into a backpack or carry-on bag. However, it is not suitable as the primary power source for high-end laptops that require 67W or more for fast charging.
