Anker 737 24,000mAh 140W Power Bank for $69.99
The Anker 737 is a powerful power bank measuring 4.6 inches x 2.2 inches x 2 inches and weighing 1.4 pounds. It’s something you can fit into your duffel bag or backpack instead of your pocket. It has two USB Type-C ports, one USB Type-A port and one USB Type-A port. The USB Type-C ports support a maximum of 140W of power, which means a single port can deliver 140W of power or both ports will deliver a total of 140W depending on what devices are connected (e.g. 70W + 70W or 100W + 40W).
When it comes to portable gaming devices, Steam Deck supports charging up to 38W, Asus ROG Ally up to 65W, Asus ROG Ally X up to 100W, and Nintendo Switch up to 18W. This means that the Anker Prime can easily charge all three gaming handhelds – even ROG Ally X – at maximum speed; you’ll even be able to play and charge at the same time.
A 20,000 mAh battery corresponds to a capacity of 74 Wh. An energy efficiency rating of 80% (which is about standard for power banks) provides approximately 59 Wh of available charge. This means this power bank will charge your Steam Deck (40 Wh) or Asus ROG Ally (40 Wh) from empty to completely full 1.5 timesAsus ROG Ally X (80 Wh) 0.75 timesand Nintendo Switch (16 Whr). 3.7 times. Here you can see why we think 20,000mAh capacity should be the bare minimum for more power-hungry gaming handhelds like the Steam Deck and the Asus ROG Ally (and especially the Ally X).
The Anker 737 is TSA certified
TSA states that the capacity of power banks cannot exceed 100 Wh for carry-on luggage (check-in is not possible under any circumstances). This Anker Prime is safely lower at 74 Whr. You may get checked out simply because the Anker 737 is a powerful looking power bank, but you shouldn’t have any problems checking it out. I have gone through many airport checkpoints and have only been cleared once – at Tokyo NRT – and passed without a problem.
