Today, Amazon is offering the powerful and high capacity Anker Prime 27,650mAh USB Power Bank for only $124.99, a hefty 31% price drop from its original $180 MSRP. This is the successor to the Anker 737 that we deemed the best Steam Deck and ASUS ROG Ally charger. It boasts an absolutely massive 250W of USB power delivery to charge all of your mobile devices simultaneously.
Anker Prime 27,650mAh Power Bank for $125
with 250W of USB Type-C Power Delivery
The Anker Prime is a hefy power bank, measuring 6.4"x2"x2.2" and weighing in at 1.5 pounds. It can be used like any other power bank; it does a fine job of charging any of your standard mobile electronics. However, its main purpose is to charge more power hungry devices like laptops, portable gaming systems, and high end phones. It has two USB Type-C ports and one USB Type-A port. Each USB Type C port supports up to 140W of Power Delivery. If you want to use both USB Type-C ports simultaneously, one will charge at 140W and the other at 100W. It can charge a Nintendo Switch OLED about 6 times, iPhone 15 Pro Max about 6 times, Steam Deck about 5 times, and an ASUS ROG Ally about 10 times.
Regarding bringing the Anker Prime on airplanes, this power bank outputs 99.54Wh, which meets the TSA requirements for carry-on baggage. Power banks need to be under 100Wh, which means this is the absolutely highest capacity you can bring on board without needing special clearance. What also makes the Prime unique compared to most other power banks is the LCD digital readout. It displays a lot of useful real-time information like remaining battery capacity, power input, and power output from each port.
The Anker Prime is an excellent Steam Deck / ASUS ROG Ally charger
The Anker Prime is an outstanding charger for the Steam Deck and ASUS ROG Ally portable gaming handhelds. The Steam Deck accepts up to 38W of USB Power Delivery and the ASUS ROG Ally accepts up to 65W. That means the Prime can fast charge two Steam Decks or ASUS ROG Allys simultaneously. In fact, you can also fast charge a Nintendo Switch at the same time because the USB Type-A port outputs 18W!
Both the ROG Ally and Steam Deck suffer from a short battery life when gaming on the go. For instance, when playing most games at 60 FPS, you're likely looking at four hours of battery life for the Steam Deck and far less with the ASUS ROG Ally, which is equipped with a measly 2600mAh battery. During our Steam Deck review, we even found games like God of War or Spider-Man would tap out in under 2-hours as well. 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.
