Amazon is currently offering the Baseus Enerfill 25,000mAh 145W Laptop Power Bank for $45.29. To achieve this price, customers must apply the coupon code "34WHWPWP" at checkout. This deal does not require an Amazon Prime membership and includes free shipping.
The power bank features dual integrated USB-C cables that can be combined to form a lanyard, a digital display, and the ability to charge up to four devices simultaneously. The primary USB-C port can deliver up to 140W of power when used alone, sufficient for charging a 16-inch MacBook Pro or handheld gaming PCs like the ASUS ROG Ally X20. When two ports are used, one can output 100W and the other 45W.
With a 25,000mAh (92.5Whr) capacity, the power bank can fully recharge various devices multiple times. Approximate recharge counts include the Nintendo Switch 2 about 4.1 times, the Steam Deck around 1.5 times, the ROG Ally and ROG Ally X at approximately 1.2 and 0.9 times respectively, and the Lenovo Legion Go S about 1.3 times. For smartphones, it can recharge an Apple iPhone 17 about 5.2 times and an iPhone 17 Pro Max around 3.7 times. These estimates account for an 80% power efficiency.
The power bank's 92.5Whr capacity is below the TSA's 100Whr carry-on limit, making it suitable for air travel.
A 20,000mAh version of the Baseus Enerfill power bank is also available for $33.29 with coupon code "RCYRSUYY", offering 100W maximum output from its USB-C cable.
