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. Note only does it carry a significant battery capacity, it also boasts an absolutely massive 250W of USB power delivery to charge even the most power hungry MacBooks, iPhones, and handheld gaming consoles (simultaneously, in most cases).
Anker Prime 27,650mAh Power Bank for $124.99
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. This is a heavier duty power bank designed to charge more power hungry devices like laptops, (multiple) portable gaming systems, and (multiple) 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, which is the max charging rate of a new 2024 MacBook Pro 16" laptop. If you want to use both USB Type-C ports simultaneously, one will charge at 140W and the other at 100W. The USB Type-A port also boasts up to 65W of charging, although that drops to 18W if you're using both USB Type-C ports at the same time.
The 27,650mAh battery capacity is more than you'll ever need on your itinerary. 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. What also makes the Anker 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.
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.
The Anker Prime is an excellent Steam Deck / ASUS ROG Ally charger
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 maybe half that on 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 could potentially 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 Anker Prime is an outstanding charger for the Steam Deck and ASUS ROG Ally portable gaming handhelds. The Steam Deck supports up to 38W, the ASUS ROG Ally up to 65W, and the Nintendo Switch up to 18W of power delivery, That means technically you could charge all three gaming consoles at the same time across all three ports. If you're traveling with a family with multiple Nintendo Switches or Steam Decks, this option will be a lot more convenient than bringing multiple power banks.
