Anker's 100W 3-port charger squeezes GaN internals into an ultra-compact body and charges several devices quickly. Reviewers pointed to the smart display, which reports charging status in real time, and noted the charger scales down for low-power devices. ActiveShield 4.0 checks temperature frequently. Users did report brief interruptions when devices switch, and the display has to be rotated by hand. It suits anyone who wants portable, high-performance charging with visual feedback.

Strengths
  • — Delivers up to 100W maximum output with advanced GaN technology for fast charging
  • — Features a smart display that shows live power, voltage, and temperature readings
  • — Compact and travel-friendly design with foldable plug and 30% smaller frame
Watch-outs
  • — Charging may briefly stop when connecting a new device due to power redistribution
  • — Display rotation requires manual adjustment with multiple presses

Anker Prime Charger
Ranked #3 in Best Gan Wall Chargers
Anker Prime Charger
4 sources2 derived$59.99as of Jul 31

The Anker Prime 100W GaN Wall Charger puts three ports and 100W maximum output into a compact block. Macworld praised the clever design and travel-friendly dimensions and noted it fast-charges most MacBook models, the 16-inch Pro excepted. The foldable plug helps it pack, though it runs quite warm under intensive use. Travelers and professionals charging several devices at once are the audience, but no cables are included.

Strengths
  • — 100W maximum charging power across USB-C ports for fast charging laptops and devices
  • — Compact dimensions measuring 1.7 × 1.1 × 2.7 inches and weighing only 6 ounces
  • — Foldable plug design reduces overall length to 7.5 centimeters for better travel portability
Watch-outs
  • — Gets very warm during fast-charging of MacBook Air M3 models
  • — Does not include charging cables for compatible devices

How they stack up

Anker 100W Ultra-Compact 3-Port GaN USB-C Charger

The Anker Phone Charger with ActiveShield 4.0 offers the smart display feature and ultra-compact design, but it's more expensive and less powerful than the Anker Prime 100W model. While it provides real-time charging feedback, the Prime model delivers higher wattage and better performance for laptops, making it more suitable for users needing maximum charging power.

Anker Prime Charger

The Anker Prime 100W charger surpasses the 67W model in power output and is better suited for MacBook Air M3 models, though it gets warm during intensive use. Compared to the Anker Phone Charger with ActiveShield 4.0, the Prime model lacks the smart display feature but offers more consistent performance for high-power devices. It's more powerful than the UGREEN but less feature-rich than the Anker Phone model.
