Anker PowerCore 737 25,600mAh Power Bank for $79.99
Includes a 65W USB PD wall charger
The Anker PowerCore 737 can be used like any other power bank; it does a fine job of charging any of your standard mobile electronics. It has two USB Type-A ports and one USB Type-C port. This is one of the largest capacity power banks that can be brought onto an airplane as carry-on. It can charge a Nintendo Switch OLED over 5 times, iPhone 15 Pro Max over 5 times, Steam Deck over 4 times, and an ASUS ROG Ally over 9 times. The power bank is physically larger than smaller capacity ones and weighs in at 1.3 pounds.
The USB Type-C port supports up to 60W Power Delivery. That's enough to charge the Steam Deck (35W) and Nintendo Switch (18W) at their maximum charging speed. It's also very close to the maximum charging speed of the ASUS ROG Ally, which caps at 65W. The two USB Type-A ports support up to 18W of total charging, which is enough to fast charge a Nintendo Switch.
What's unique about this deal compared to some other similar deals we've posted is that this one also comes with a USB Type-C wall charger that supports 65W of Power Delivery. There's no need to buy another wall charger or scavenge one from another power bank you might have sitting around.
The Anker 737 is our pick for best Steam Deck / ASUS ROG Ally charger
We picked the newer Anker 737 as our favorite portable charger for the Steam Deck and ASUS ROG Ally portable gaming handhelds. 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, at most. We even found games like God of War or Spider-Man would tap out in under 2 hours on the Steam Deck. 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.
