100W GaN charger with smart display

The Anker B121B delivers up to 100W from any USB-C port using GaN technology that sustains peak output longer than average chargers. A built-in high-definition display shows real-time power, voltage and temperature with animated visuals. Touch control adds direct interaction. The foldable plug and 330% smaller frame measure just 2.72 x 2.17 x 1.34 inches for easy daily carry.

GaN thermals and adaptive low-power mode

Advanced GaN components keep the charger running cool while maintaining steady 100W output during extended sessions. The smart display provides live temperature readouts so you can monitor thermal performance at a glance. When a connected device draws 5W or less for one minute, USB-C2 or USB-A automatically switches to 95W + 5W Low-Current Mode, safely charging earbuds and other low-power accessories without user intervention.

Three-port layout with included 4.9 ft cable

Two USB-C ports and one USB-A port charge laptops, tablets and phones simultaneously, with intelligent power distribution across all three. The package includes a 4.9 ft USB-C to USB-C cable so it works straight out of the box. The compact footprint frees desk space and fits tight travel bags, while the foldable plug eliminates snag risk. Not suited for buyers who need more than three ports or a battery-backed power bank for off-grid use.

Questions about this item

How do I install the Anker B121B and what step is most often missed?

Unfold the plug, insert it into a wall outlet, then connect devices to the USB-C or USB-A ports. The step many skip is waiting one minute at or below 5 W on USB-C2 or USB-A so the charger automatically enters 95 W + 5 W Low-Current Mode for earbuds or other low-power gear.

What maintenance or replacement will this charger need later?

The unit itself has no user-serviceable parts. Only the included 4.9 ft USB-C to USB-C cable may wear over time and need replacing; the welcome guide and 18-month warranty cover defects but no routine upkeep is required.

What limit appears first when I run the B121B at full load for a long period?

The smart display will show rising temperature as the first sustained-use constraint. GaN technology sustains peak 100 W output up to twice as long as typical 100 W chargers before thermal throttling reduces power.
