  • Steam Deck (40Whr): About 1.9 times
  • Apple iPhone 16 (14Whr): About 4.2 times
  • Apple iPhone 16 Plus (18Whr): About 3.3 times

Equipped with three output ports, this power bank includes a built-in 45W USB Type-C cable, a standalone 45W USB Type-C port, and a USB Type-A port capable of delivering up to 18W. The 45W Power Delivery ensures optimal charging speeds for the Nintendo Switch (18W) and Steam Deck (40W). Additionally, it efficiently powers Apple iPhones, with ChargerLAB confirming a maximum charging rate of around 30W, even for Pro Max models.

One standout feature is the built-in cable, common in modern, higher-end power banks. This eliminates the need to carry additional USB Type-C cables. When traveling, the USB plug can double as a convenient lanyard. Built to last, the cable boasts a respectable 44-pound break strength, while the lanyard loop attached to the power bank holds up to 13 pounds.

What About the New Nintendo Switch 2?

The Nintendo Switch 2 hits shelves on June 5, and though it’s portable, Nintendo claims a minimum of just two hours of battery life during intensive gaming sessions. While suitable for short commutes, extended trips or prolonged use away from outlets demand a reliable power bank. Although we highlight top choices for the Switch 2, the Iniu power bank remains a strong contender, especially if the Switch 2 supports higher charging outputs.
