For a limited time, Amazon is offering the powerful and high capacity Anker PowerCore 737 24,000mAh USB Power Bank for only $90, a massive 40% price drop from its original $150 MSRP. This power bank dropped to $110 on Black Friday, but it's even less expensive right now. This is close to the highest capacity power bank you're allowed to bring on airplane carry-on, and it also boasts an absolutely massive 140W of USB power delivery. It's one of the best Steam Deck and ASUS ROG Ally chargers.
Anker 24,000mAh Power Bank for Only $90
with 140W of USB Type-C Power Delivery
The Anker PowerCore 737 boasts an impressive 24,000mAh battery capacity, which is just under the TSA's 27,000mAh limit; it can charge a Nintendo Switch OLED about 5 times, iPhone 15 Pro Max about 5 times, Steam Deck about 4 times, and an ASUS ROG Ally about 9 times. It has two USB Type-C ports and one USB Type-A porth with up to 140W of Power Delivery on a single USB port. That's enough power to charge a MacBook Pro 16 at its fastest rated charging speed. If you want to use all three ports simulatenously, the two Type-C ports charges at up to 122W total and the Type-A post up to 18W.
What makes this power bank unique compared to most other power banks is the LCD digital readout which displays a lot of useful real-time information like remaining battery capacity, power input, and power output from each port. The power bank measures 6"x2"x2" and weighs in at 1.4 pounds.
The Anker 737 is our pick for best Steam Deck / ASUS ROG Ally charger
We picked the Anker 737 as our favorite portable charger for the Steam Deck and ASUS ROG Ally portable gaming handhelds. The Steam Deck accepts up to 38W of USB Power Delivery and the ASUS ROG Ally accepts up to 65W. That means the Prime can charge two Steam Decks or ASUS ROG Allys simultaneously (or three Nintendo Switches) at their maximum charging rate. Both the ROG Ally and Steam Deck suffer from a short battery life when gaming on the go. For instance, when playing most games at 60 FPS, you're likely looking at four hours of battery life for the Steam Deck and far less with the ASUS ROG Ally, which is equipped with a measly 2600mAh battery. During our review, we even found games like God of War or Spider-Man would tap out in under 2-hours as well. 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.
