Amazon is currently offering the Baseus 20,000mAh 45W Power Bank for $20.99 when a specific coupon code is applied. This deal does not require an Amazon Prime membership.
The power bank features a 20,000mAh (74Whr) battery capacity. With an estimated 80% power efficiency, it can recharge a Nintendo Switch (16Whr) approximately 3.7 times, a Nintendo Switch 2 (19Whr) about 3.1 times, and a Steam Deck (40Whr) around 1.5 times. It can also recharge an Apple iPhone 17 (14.3Whr) about 4.1 times or an iPhone 17 Pro Max (19.8Whr) approximately 3 times.
Connectivity options include four USB outputs: two integrated 45W USB-C cables that can be connected to form a lanyard loop, an additional 45W USB-C port, and a 33W USB-A port. The 45W Power Delivery output allows for simultaneous charging and playing on devices like the Nintendo Switch and Steam Deck at their maximum charging rates. The inclusion of built-in USB-C cables eliminates the need to carry a separate cable.
