Baseus EnerGeek GR12 Power Bank Launches With 20,800mAh Capacity

Baseus released the EnerGeek GR12 power bank with a larger battery and higher output than its predecessor. The device targets users who carry multiple gadgets and need fast charging without swapping cables.

The new portable charger features four ports and a digital display for live wattage tracking.

The GR12 sits in Baseus's EnerGeek line alongside the cheaper GR11 model that includes a retractable USB-C cable. It uses two USB-C ports and two USB-A ports to charge four devices simultaneously.

• Capacity: 20,800mAh (8 x 2,600mAh cells)
• Max Output: 145W combined; USB-C ports up to 100W each; USB-A ports up to 33W each
• Input Charging: 65W (approx. 2 hours for full charge)
• Dimensions: 2.0 x 1.7 x 6.1 inches
• Weight: 1.1 pounds

Each USB-C port can deliver up to 100W when charging a single device or split power between two laptops at 100W and 45W, or 65W and 65W. The two USB-A ports provide up to 33W each. When all four ports run at once, the unit caps out at 145W combined output.

The battery contains eight 2,600mAh cells for a total of 20,800mAh. Baseus claims this capacity can fully charge an iPhone 16 Pro roughly 3.6 times or power a 13-inch MacBook Air once per cycle. The unit supports PPS, PD, and UFCS charging standards for broad compatibility with smartphones and laptops.

The GR12 measures 2.0 by 1.7 by 6.1 inches and weighs 1.1 pounds. Recharging the power bank itself takes about two hours at 65W input. A digital display on the front shows remaining capacity and live output wattage.

Baseus lists the GR12 at $99.99 in the US market through Amazon. That price sits above the $79.99 GR11 model, which trades a smaller 20,000mAh battery for a built-in retractable cable.

The EnerGeek GR12 ships with confirmed specs and pricing. It offers high combined output across four ports while maintaining a compact form factor for portable use.
