Anker makes great power banks, but the caveat is that they are a lot more expensive than other brands. If you're on a budget, Amazon is offering this powerful and high capacity Poweradd Pro 27,000mAh 140W USB Power Bank for only $55.99 after you clip the 30% off coupon. This is an outstanding price for a power bank that features a spacious 27,000mAh capacity and a hefty 140W of charging output. If you were to buy a comparable Anker model, you'd be paying double the price. This power bank can charge a Nintendo Switch, Steam Deck, and ASUS ROG ALLY simultaneously across all three of its USB ports.

The Poweradd Pro can be used like any other power bank; it does a fine job of charging any of your standard mobile electronics. However, its main purpose is to charge more power hungry devices like laptops, portable gaming systems, and high end phones. It has two USB Type-C ports and one USB Type-A port. Each USB Type C port supports up to 140W of Power Delivery. If both ports are used at the same time, they can each deliver up to 65W. The USB Type-A port delivers up to 22.5W. This is one of the biggest capacity "pocketable" power banks around, so it measures a hefty 6"x2"x2" and weighs in at 1.6 pounds.
The Poweradd Pro is an excellent Steam Deck / ASUS ROG Ally charger
The Poweradd Pro is an outstanding charger for handheld gaming consoles 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 2 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 Steam Deck accepts up to 38W of USB Power Delivery, ASUS ROG Ally accepts up to 65W, and the Nintendo Switch up to 18W. That means the Poweradd Pro can theoretically charge a Steam Deck, ASUS ROG Ally, and Nintendo Switch at their maximum charging rate all at the same time. In real world applications however, most power banks thermally throttle themselves from the excess heat generated when they are forced to charge at the max wattage for a long time.
The Poweradd Pro is TSA-approved
The Poweradd Pro features a 27,000mAh 97.5Whr capacity, which is just under TSA's 27,000mAh 100Whr limit so it can be brought onto airplanes. The 97.5Whr rating is when the power bank is pushed to its max (and even then it probably won't ever hit that number). If a TSA official actually does take the initiative to test the wattage on your power bank, you're well in the clear.
The Poweradd Pro has a digital display like the pricier Anker Prime
The Poweradd Pro also has some extra features you'd normally only find on premium power banks, like a LCD digital readout which displays a lot of useful real-time information like remaining battery capacity, power input, and power output from each port.
