The Best Anker Power Banks for Steam Deck Are 50% Off for Cyber Monday

The Anker 737 is a hefty power bank, measuring 4.6"x2.2"x2" and weighing in at 1.4lbs. This is something you'd put in your travel bag or backpack instead of your pocket. It has 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.

Alternative Deal: Anker Prime 27,500mAh Power Bank

Woot! is also offering the Anker Prime 27,650mAh USB Power Bank for only $99.99. This is again the best price we've seen for 2024 (the previous lowest price was $119.99). The Anker Prime is the successor to the Anker 737 with a couple of noticeable upgrades like a higher power capacity (but still within the limit for TSA eligibility), higher power delivery output (250W vs 140W) and a higher charging rate through USB Type-A (65W vs 18W).

Black Friday vs Cyber Monday

In most instances, you can consider Cyber Monday as a one day extension of Black Friday. Traditionally, Black Friday was known as the "retail holiday," where the best deals were found in-store, and Cyber Monday was known as the "online holiday," where the best deals were online only. Although today the lines are very much blurred, it is still true that many online only retailers still consider Cyber Monday the sale event of the year instead of Black Friday. Expect some amazing sales to come out of online-only sites like Amazon, Newegg, Dell, HP, Lenovo and several online-only deals from traditional retailers like Best Buy, Target, and Walmart.
