Baseus Blade 20,000mAh 100W Power Bank for $49.79

Amazon Prime member exclusive

The Baseus Blade features a slim and lightweight form factor that measures only 0.7 inches thin and weighs in at 17 ounces. It has four ports: two USB Type-C ports and two USB Type-A ports. The USB Type-C ports deliver a combined total of 100W of power output (charging your devices) and 65W of power input (charging your power bank). The USB Type-A ports deliver up to 18W. The power bank can be brought onto airplaines since it is well below TSA's 27,000mAh threshold. Despite the thin profile, the Baseus Blade is able to pack in a digital readout that displays a lot of useful real-time information like remaining battery capacity, power input, and power output from each port.

The Baseus Blade can fast charge a Steam Deck or ROG Ally

This is a great charger for gaming handhelds like the Steam Deck, ROG Ally, and Switch. Both the ROG Ally and Steam Deck suffer from a short battery life when gaming on the go. During our Steam Deck review, we found games like God of War or Spider-Man would tap out in under two hours. At the end of the day, you'll never get the full potential out of your Steam Deck or ROG Ally if you're not equipped with a decent portable charger. The Baseus Blade can fast charge all three at their maximum rate. It supports up to 100W of charging over USB-C, which is more than enough for the Steam Deck's charging rate of 38W, the Rog Ally's charging rate of 65W, and the Nintendo Switch's charging rate of 18W.

The Baseus Blade can fully charge a Steam Deck or ROG Ally

The ROG Ally and Steam Deck both consume about 40Whr going from full to empty. The Baseus Blade has a 20,000mAh capacity or 74Whr battery. If you factor in 80% power efficiency, then you should expect the Baseus Blade to charge either gaming handheld about 1.5 times. That's why it's better to get a larger capacity like this than a 10,000mAh power bank, which cannot charge these handhelds from empty to full even once.
