The Anker 737 is our pick for the best Steam Deck/ASUS ROG Ally charger

We've chosen the Anker 737 as our favorite portable charger for the Steam Deck and ASUS ROG Ally portable gaming devices. The Steam Deck accepts up to 38W of USB Power Delivery and the ASUS ROG Ally accepts up to 65W. This means that the Prime can charge Two Steam Decks or ASUS ROG Allys simultaneously (or three Nintendo Switches) at maximum charging rate. Both the ROG Ally and Steam Deck suffer from short battery life when gaming on the go. For example, when playing most games at 60fps, you're likely looking at four hours of battery life for the Steam Deck and much less with the ASUS ROG Ally, which is equipped with a 2,600mAh battery. During our review, we found that games like God of War or Spider-Man would finish in under two hours as well. Ultimately, you'll never get the full potential from your Steam Deck or ROG Ally if you're not equipped with a decent portable charger.
