INIU 20,000mAh 45W USB Power Bank

• List Price: $39.99
• Deal Price: $18.31 (Save 54%)
• Where: Amazon
• Promo Code: E58LOYPK

This Iniu power bank packs a substantial 20,000mAh (74Whr) battery capacity. Taking into account standard 80% efficiency, 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

The unit features three output ports:

• A built-in 45W USB Type-C cable
• A separate 45W USB Type-C port
• A USB Type-A port supporting up to 18W

The 45W Power Delivery ensures fast charging for both the Nintendo Switch (which charges at 18W) and the Steam Deck (which supports up to 40W). Even for the latest Apple iPhone 16 series, this power bank delivers more than enough juice, as ChargerLAB testing shows that even the Pro Max variant peaks out at around 30W.

One standout feature is the built-in USB Type-C cable, which is increasingly common in premium models. No need to carry an extra cable—it clips onto the power bank to double as a lanyard. The cable is durable, tested with a break strength of 44 pounds, while the lanyard loop itself holds up to 13 pounds of force.

What About the Upcoming Nintendo Switch 2?

The Nintendo Switch 2 is set to launch on June 5, and although it will be a portable device by design, Nintendo only guarantees a minimum of 2 hours of gameplay in intensive titles. While that might cover a quick commute, longer trips or flights will demand a reliable power bank. The Iniu model featured here could be an ideal match, especially if the new Switch supports higher wattage charging.
