Baseus has expanded its EnerGeek lineup with the GR12, a 20,800mAh power bank built for users who carry more than one demanding device. Its headline feature is a total output of up to 145W, which places it well above typical portable chargers in this class.
The GR12 is now listed on Amazon in the United States at $99.99. That makes it more expensive than the EnerGeek GR11, which sells for $79.99, but the new model answers with a larger battery and a more aggressive power profile.
Two USB-C ports take the lead
The strongest argument for the GR12 is its charging layout. Baseus fitted it with two USB-C ports and two USB-A ports, allowing the power bank to handle as many as four devices at once.
Each USB-C port can deliver up to 100W when used on its own. When both are active, the output can be split into 100W and 45W, or 65W and 65W, making it possible to charge one laptop at full pace or power two laptops at the same time.
The two USB-A ports are not merely secondary extras. Each one supports up to 33W, and when all four ports are used together, the combined output reaches 145W.
Large capacity with broad fast-charging support
Inside the body sits a 20,800mAh battery made up of eight 2,600mAh cells. Baseus says that capacity is enough to recharge an iPhone 16 Pro about 3.6 times or fully charge a 13-inch MacBook Air once.
The GR12 also supports several widely used fast-charging standards, including PPS, PD, and UFCS. That broad compatibility makes it suitable for many smartphones, including a number of Chinese models that rely on specific charging protocols.
Recharging the power bank itself is handled through a 65W input. Baseus says a full recharge takes about two hours, which helps keep the unit practical for daily mobile use.
Digital display and portable dimensions
Another notable addition is the built-in digital display on the front. It shows key information such as remaining battery capacity and the current charging output in real time.
Physically, the GR12 measures 2.0 x 1.7 x 6.1 inches and weighs 1.1 pounds. That keeps it portable enough for a high-capacity power bank, even if it is clearly aimed at users who prioritize output over compactness.
The launch also reinforces Baseus’ strategy in the EnerGeek series. The company still offers the GR11 as a cheaper option with a 20,000mAh battery and a retractable USB-C cable, while the GR12 moves higher up the range with a larger capacity and stronger output.
