If you're in the market for a power bank that can keep up with the high demands of gaming handhelds like the Steam Deck or ROG Ally X, Amazon has an unbeatable deal on offer. The Anker PowerCore 737 24,000mAh 140W Power Bank is currently available for just $49.99 through Woot, an Amazon-owned marketplace vendor. This price is a whopping $20 less than the last time we reported on it, and it's unlikely to drop any further. Having personally used this power bank for several years across numerous flights and road trips, I can attest to its durability and reliability.

The Anker 737 is a top choice for charging your Steam Deck, thanks to its robust capabilities. This power bank measures 4.6"x2.2"x2" and weighs about 1.4lbs, making it more suited for your travel bag or backpack rather than your pocket. It features two USB Type-C ports and one USB Type-A port, with the Type-C ports capable of delivering up to 140W of power. This allows for flexible charging configurations such as 140W from a single port or a combination like 70W + 70W or 100W + 40W.
For gaming handhelds, the Steam Deck charges at up to 38W, the Asus ROG Ally at up to 65W, the Asus ROG Ally X at up to 100W, and the Nintendo Switch at up to 18W. The Anker 737 can charge all these devices at their maximum rate, allowing for simultaneous play and charge.
A 24,000mAh battery translates to a 74Whr capacity. With an 80% power efficiency rating, you get about 59Whr of usable charge. This means the power bank can fully charge a Steam Deck (40Whr) or Asus ROG Ally (40Whr) approximately 1.5 times, an Asus ROG Ally X (80Whr) about 0.75 times, and a Nintendo Switch (16Whr) around 3.7 times. This capacity underscores why a 20,000mAh power bank is the minimum recommended for power-intensive gaming handhelds.
The Anker 737 is TSA-approved
The TSA allows power banks with a capacity under 100Whr in carry-on luggage. At 74Whr, the Anker 737 comfortably fits within this limit. While its size might prompt occasional checks, it's fully compliant with TSA regulations. I've traveled extensively with this power bank and only faced a single check at Tokyo NRT, which resulted in no issues.
