Today, Amazon is offering the powerful and high capacity Anker Prime 20,000mAh USB Power Bank for only $89.98, a hefty 31% price drop from its original $130 MSRP. This is the successor to the Anker 737 that we deemed our favorite Steam Deck and ASUS ROG Ally charger. It boasts an absolutely massive 200W of USB power delivery to charge all of your mobile devices simultaneously.
Anker Prime 20,000mAh Power Bank for $90
with 200W of USB Type-C Power Delivery
The Anker Prime 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 100W of Power Delivery. In fact, both ports can charge 100W at the same time. If you want to charge using all three ports simultaneously, then the power distribution will be 100W (Type C), 60W (Type-C) and 40W (Type-A). The 20,000mAh is under the TSA’s 27,000mAh limit so it can be brought onto airplanes; it can charge a Nintendo Switch OLED about 4 times, iPhone 15 Pro Max about 4 times, Steam Deck about 3 times, and an ASUS ROG Ally about 7 times.
What makes the Prime unique compared to most other power banks is the LCD digital readout which displays a lot of useful real-time information like remaining battery capacity, power input, and power output from each port. The power bank measures 5″x2″x2″ and weighs in at 1.2 pounds.
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 charge three Steam Decks or two ASUS ROG Allys simultaneously at their maximum charging rate. 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 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.
