Amazon is currently offering the Baseus 20,000mAh 45W Power Bank for $20.99, a price achievable with the coupon code "OJAGXRO6". This deal is available to all customers, not just Amazon Prime members, as part of the retailer's Back to School Sale.
The portable power bank features a 20,000mAh capacity, equivalent to 74Whr. When accounting for an 80% power efficiency, this capacity can recharge a Nintendo Switch approximately 3.7 times, a hypothetical Nintendo Switch 2 around 3.1 times, and a Steam Deck about 1.5 times. It also offers approximately 4.1 recharges for an Apple iPhone 17 and 3 recharges for an iPhone 17 Pro Max.
This Baseus power bank is equipped with four USB outputs. Two of these are built-in 45W USB-C cables that can connect together to form a lanyard loop. Additionally, there is another 45W USB-C port and a 33W USB-A port. The 45W Power Delivery output is capable of charging the Nintendo Switch, Nintendo Switch 2, and Steam Deck at their maximum charging rates, allowing for simultaneous play and charging without battery depletion. The integrated USB-C cables are a notable convenience, eliminating the need to carry separate charging cables.
