If you're looking for an Anker power bank that can handle the demands of a power guzzling gaming handheld like the Steam Deck or ROG Ally X, Amazon is offering an outstanding deal right now. You can pick up an Anker PowerCore 737 24,000mAh 140W Power Bank for just $49.99. Woot, the marketplace vendor, is owned by Amazon. This beats out the lowest price we last posted by about $20 and I don't think it can go any lower. I have owned this exact power bank for a few years now and highly recommend it; it has been on multiple flights and road trips and is still good as new.
Anker 737 24,000mAh 140W Power Bank for $49.99
The Anker 737 is one of our favorite Steam Deck chargers. This is a relatively hefty power bank, measuring 4.6"x2.2"x2" and weighing in at 1.4lbs. It's something you'd put in your travel bag or backpack instead of your pocket. It's equipped with two USB Type-C ports and one USB Type-A port. The USB Type-C ports support a maximum of 140W of power delivery. That means a single port could deliver 140W, or both ports will deliver a combination of 140W depending on which devices are plugged in (for example, 70W + 70W or 100W + 40W).
In terms of gaming handhelds, the Steam Deck supports up to 38W of charging, the Asus ROG Ally up to 65W, the Asus ROG Ally X up to 100W, and the Nintendo Switch up to 18W. That means the Anker Prime can easily charge all three gaming handhelds – even the ROG Ally X – at their maximum rate; you'll even be able to play and charge simultaneously.
A 20,000mAh battery equates to a 74Whr capacity. An 80% power efficiency rating (which is about standard for power banks) gives you about 59Whr of available charge. That means this power bank will charge a Steam Deck (40Whr) or Asus ROG Ally (40Whr) from empty to completely full 1.5 times, an Asus ROG Ally X (80Whr) 0.75 times, and a Nintendo Switch (16Whr) about 3.7 times. You can see here why we think a 20,000mAh capacity should be the bare minimum for more power hungry gaming handhelds like the Steam Deck and Asus ROG Ally (and especially the Ally X).
The Anker 737 is TSA-approved
TSA states that power banks must be under 100Whr in capacity for carry-on (check-in is not allowed under any circumstances). This Anker Prime is safely under that at 74Whr. You might get checked simply because the Anker 737 is a hefty-looking power bank, but you shouldn't have any problems getting it cleared. I've gone through plenty of airport checkpoints and have only been checked once – at Tokyo NRT – and cleared without a problem.
