Anker Charger (100W, 3 Ports, Smart Display) Silver
The Anker Charger (100W, 3 Ports, Smart Display) Silver is a compact GaN charger built to power a laptop, phone, and accessory all at once, while showing live charging details on a built-in screen. Its advanced GaN technology delivers a steady 100W max output on either of its two USB-C ports, and Anker states it sustains peak performance roughly twice as long as an average 100W charger. The dynamic smart display shows real-time power, voltage, and temperature readouts with animated visuals, along with milestone tracking of total charging hours, and it rotates 90° with each long press to match however the charger is oriented. A foldable plug and a frame roughly 30% smaller than earlier designs make it easy to pack, while ActiveShield 4.0 monitors temperature more than a million times a day to keep charging stable. During three-port charging, the USB-C1 port is prioritized for maximum output, and the USB-C2 or USB-A port automatically switches to a low-current mode for devices like earbuds or a smartwatch.

Best Suited For
- Laptop users needing full-speed charging on the go, since either USB-C port delivers a steady 100W for MacBook Pro, Chromebook, or similar devices
- Multi-device users who want to charge a laptop, phone, and earbuds simultaneously from one compact charger
- Buyers who want visibility into their charging, given the smart display’s live power, voltage, and temperature readouts
Recommended Action: Use a cable rated for 100W or higher to reach the charger’s full USB-C1/USB-C2 speed, since a lower-rated cable will cap the output below the charger’s maximum.
