Amazon is offering the Talix 20,000mAh 140W Power bank for $38.99 with free shipping after applying the 57% off coupon code “KHA1WFIH.” The deal does not require an Amazon Prime membership and is described as limited-time.
The power bank has a 20,000mAh battery, rated at 74Wh, and three outputs: a 140W USB-C port, a 65W USB-C port and a 30W USB-A port. Talix is backed by Lenovo, and the product is described as closely matching the Lenovo Thinkplus Fluxo power bank apart from its branding.
Its 140W output can charge gaming handhelds at their maximum charging rate, including the Asus ROG Xbox Ally X and Lenovo Legion Go S. It can also charge many laptops, with the source noting compatibility with the 2026 Apple MacBook Pro and certain Lenovo ThinkPad and Legion laptops that support 140W input.
With an estimated 80% power efficiency, the 74Wh battery could provide around 3.3 full charges for a Nintendo Switch 2, 1.2 to 1.5 for a Steam Deck, and about one for a ROG Xbox Ally or Lenovo Legion Go S. The estimate is around 0.7 charges for a ROG Xbox Ally X, 4.2 for an iPhone 17 and three for an iPhone 17 Pro Max.
The 74Wh capacity is below the stated TSA carry-on limit of 100Wh, so the power bank can be brought on airplanes in carry-on luggage.
