A significant discount is available on the Baseus 20,000mAh Power Bank during Amazon's Prime Day event, bringing its price down to $29.99. The portable charger boasts 140W of Power Delivery, making it a capable option for keeping power-hungry devices, particularly handheld gaming PCs, charged.
Powering Handheld Gaming PCs
The Baseus power bank features a 20,000mAh (74Whr) battery. With an estimated 80% efficiency, it can provide approximately 1.5 full charges for a 40Whr device like the Steam Deck or Asus ROG Ally. For devices with larger batteries, such as an 80Whr Xbox Ally X, it offers about 0.7 charges, and for a 55Whr Legion Go, it provides around 1.1 charges. Nintendo's Switch or Switch 2, with their 20Whr batteries, can expect up to three full charges.
The power bank is equipped with four ports: two 100W USB-C ports, a retractable 100W USB-C cable, and a USB-A port. While the total maximum output is rated at 145W, each individual USB-C port is limited to 100W. For devices that support 140W charging, such as some MacBook Pro models, users would need to utilize two USB-C cables for dual charging.
However, the 100W maximum output per port is sufficient for all current handheld gaming PCs. The Steam Deck supports up to 45W charging, the Asus ROG Ally up to 65W, the Legion Go up to 100W, and the Nintendo Switch models between 20W and 30W. This means these devices can be charged at their maximum supported speeds, even while in use simultaneously.
