INIU 20K mAh 65W Fast-Charging Power Bank

Original: $59.99 | Save 56% | Now $26.46 at Amazon

While INIU markets this as their most compact 20K mAh model (measuring just 4×3 inches), it maintains a thicker 1.1-inch profile weighing approximately 11 ounces. The device features three charging ports: one 65W USB-C, one 36W USB-C, and an 18W USB-A port. Importantly, the maximum simultaneous output across all ports caps at 65W despite the combined 119W potential output.

20K mAh capacity provides multiple charges for gaming devices

With its substantial 74Wh capacity (accounting for standard 80% efficiency), here's how many full charges you can expect:

Nintendo Switch 2 (18Wh): ~3.3 charges
Nintendo Switch (16Wh): ~3.7 charges
Steam Deck (40Wh): ~1.5 charges
Asus ROG Ally (40Wh): ~1.5 charges
ROG Ally X (80Wh): ~0.7 charges
Lenovo Legion Go (50Wh): ~1.2 charges
Legion Go S (55Wh): ~1 charge
iPhone 16 (14Wh): ~4.2 charges
iPhone 16 Plus (18Wh): ~3.3 charges

65W output enables fast charging during gameplay

This superior 65W output outperforms most chargers in its price range, supporting max charging rates for popular devices: Nintendo Switch/2 (18-20W), Steam Deck (35W), and ROG Ally (65W). While newer models like the Ally X and Legion Go can handle 100W charging, using the included 65W charger helps preserve battery longevity.

TSA-approved for air travel

The 74Wh capacity easily complies with TSA's 100Wh limit for carry-on electronics, making it airport-safe.
