For a limited time, Amazon is offering the powerful and high-capacity Anker PowerCore 737 24,000mAh USB power bank for just $90, a massive 40% off the original MSRP of $150. This power bank dropped to $110 on Black Friday, but it’s even cheaper right now. This is almost the highest capacity power bank you can carry in an airplane carry-on, and it also has an absolutely massive 140W USB power delivery. It’s one of the best Steam Deck and ASUS ROG Ally chargers.

The Anker PowerCore 737 has an impressive battery capacity of 24,000 mAh, which is just under the TSA limit of 27,000 mAh; It can charge a Nintendo Switch OLED about five times, an iPhone 15 Pro Max about five times, a Steam Deck about four times, and an ASUS ROG Ally about nine times. It features two USB Type-C ports and one USB Type-A port with up to 140W power delivery on a single USB port. That’s enough power to charge a MacBook Pro 16 at the highest rated charging speed. If you want to use all three ports at the same time, the two Type-C ports charge up to 122W in total and the Type-A port charges up to 18W.
What makes this power bank unique compared to most other power banks is the digital LCD display that shows a lot of useful real-time information such as remaining battery capacity, power consumption and power output on each port. The power bank measures 6 x 2 x 2 inches and weighs 1.4 pounds.
The Anker 737 is our pick for the 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 USB Power Delivery and the ASUS ROG Ally accepts up to 65W. This means the Prime can charge two Steam Decks or ASUS ROG Allys at the same time (or three Nintendo Switches) with maximum charging rate. Both the ROG Ally and the Steam Deck suffer from short battery life when gaming on the go. For example, if you play most games at 60 FPS, you’ll probably expect four hours of battery life with the Steam Deck and significantly less with the ASUS ROG Ally, which has a paltry 2600mAh battery. In our testing, we even found that games like God of War or Spider-Man would also be available in under two hours. Ultimately, you’ll never be able to use your Steam Deck or ROG Ally to its full potential if you’re not equipped with a decent portable charger.
