• Price: $18.31 (Save 54% off the original $39.99)
• Where: Amazon
• Promo Code: E58LOYPK

The Iniu 20,000mAh (74Whr) power bank delivers serious juice. Taking into account standard 80% efficiency rates, here’s how many full recharges you can expect for popular devices:

• Nintendo Switch (16Whr): ~3.7 times
• Steam Deck (40Whr): ~1.9 times
• Apple iPhone 16 (14Whr): ~4.2 times
• Apple iPhone 16 Plus (18Whr): ~3.3 times

Equipped with three output ports—45W USB Type-C (with built-in cable), a standalone 45W USB Type-C port, and a USB Type-A port delivering up to 18W—this power bank is more than capable of fast-charging both the Nintendo Switch (18W) and Steam Deck (40W) at their optimal speeds. It also performs well with Apple's iPhone 16 lineup, even though ChargerLAB tests show the charging cap maxing out around 30W for most models.

One standout feature is the built-in USB Type-C cable, commonly found in higher-end power banks. No need to carry an extra cable—just clip it onto the unit when not in use for a convenient lanyard-style setup. The cable is durable, tested with a break strength of 44 pounds, while the lanyard loop itself holds up to 13 pounds before breaking.

What About the Upcoming Nintendo Switch 2?

The Nintendo Switch 2 is set to release on June 5th and promises enhanced portability. However, Nintendo only guarantees a minimum of 2 hours of battery life during demanding gameplay. That might be fine for short commutes, but for extended travel or all-day usage away from an outlet, a high-capacity power bank like this Iniu model becomes essential. While official charging specs for the Switch 2 remain unclear, the Iniu 45W power bank remains a smart and flexible option regardless of what lies ahead.
