As part of the October Prime Day Sale, Amazon is offering the Anker PowerCore 737 USB Power Bank for only $89.99. This portable battery features a generous 20,000mAH capacity and a powerful 140W power output, but is still TSA-approved. It can fast charge a Steam Deck or ASUS Rog Ally from empty to full multiple times over.
Anker PowerCore 737 24,000mAh Power Bank for $89.99
with 140W of USB Type-C Power Delivery
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-C ports and one USB Type-A port. One of the USB Type-C ports is bi-directional, meaning it can be used to charge devices AND it can also be used to charge the power bank itself. The massive 24,000mAh is just under the TSA’s 27,000mAh limit. I recently brought this power bank to a trip to Japan. At the security checkpoint it was removed and the wattage fully tested. It passed with flying colors and I was able to get through security with my power bank in tow. Because of the larger capacity, it weighs in at a heftier 1.4 pounds.
The Anker 737 is our pick for best Steam Deck / ASUS ROG Ally charger
We picked the Anker 737 as one of our favorite portable chargers for the Steam Deck and ASUS ROG Ally portable gaming handhelds. This is an outstanding charger for handheld gaming consoles like the Steam Deck, ROG Ally, and Switch. Both the ROG Ally and Steam Deck suffer from a short battery life when gaming on the go. During our Steam Deck review, we found games like God of War or Spider-Man would tap out in under 2 hours. 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. The Steam Deck accepts up to 38W of USB Power Delivery, ASUS ROG Ally accepts up to 65W, and the Nintendo Switch up to 18W. The Anker 737 could theoretically charge a Steam Deck, ROG Ally, and Switch at their maximum charging rate all at the same time, but we wouldn’t recommend that because the thermal protection would kick in and throttle the output.
The Anker 737 power bank is TSA-approved
TSA requires that power banks be in carry-on bags only (they are not allowed in check-in luggage). Power banks must also be under 27,000mAh or 100Whr in capacity. The Anker power bank’s 24,000mAh capacity is =under TSA’s 27,000mAh 100Whr limit so it can be brought onto airplanes without worry. If a TSA official actually does take the initiative to test the wattage on your power bank, you’re well in the clear.
