Amazon is offering a significant discount on the Baseus Blade 20,000mAh 100W power bank, dropping its price to $39.49 when using the code Z6J1ANOV. This deal comes ahead of the Black Friday shopping season and does not require an Amazon Prime membership.
The Baseus Blade distinguishes itself with an ultra-slim profile, measuring only 0.7 inches thick. This design contrasts with the bulkier form factor of many high-capacity power banks, allowing it to fit easily into laptop bag sleeves or backpack compartments. While slim, it weighs approximately one pound, which is comparable to other power banks in its capacity class.
Despite its slender design, the power bank features four ports: two USB Type-C ports capable of 100W Power Delivery each, and two USB Type-A ports with 30W output each. The total maximum output across all ports is capped at 100W, meaning the combined output will be throttled to 100W if multiple ports are used simultaneously.
With its 20,000mAh (74Whr) capacity, the Baseus Blade can recharge various portable gaming devices multiple times. It is estimated to provide approximately 3.3 charges for a Nintendo Switch 2, 1.2 to 1.5 charges for a Steam Deck, one charge for a ROG Ally or Legion Go S, and around 0.7 charges for the ROG Ally X. For smartphones, it can deliver about 4.2 charges to an iPhone 17 and 3 charges to an iPhone 17 Pro Max.
The 100W output capability of the USB-C ports ensures fast charging for most devices. While the power bank can deliver up to 100W, it intelligently adjusts to the maximum rate supported by the connected device. For instance, the Nintendo Switch and Switch 2 draw up to 18W-30W, the Steam Deck up to 45W, and the Legion Go S up to 55W. The ROG Ally X can charge at its maximum rate of 100W.
Furthermore, the 74Whr battery capacity is compliant with TSA regulations for carry-on luggage, falling below the 100Whr limit, making it suitable for air travel.
