Use code: 'WN9GQJRA'

This INIU power bank features a substantial 20,000mAh or 74Whr battery capacity. With an 80% power efficiency, here's how many full recharges you can expect for each gaming handheld:

• Nintendo Switch (16Whr): Approximately 3.7 times
• Steam Deck (40Whr): Approximately 1.9 times
• Asus ROG Ally (40Whr): Approximately 1.9 times
• Asus ROG Ally X (80Whr): Approximately 1 time
• Lenovo Legion Go (50Whr): Approximately 1.5 times

The power bank comes equipped with three output ports: one 65W USB Type-C port, one 36W USB-Type-C port, and one USB Type-A port with up to 18W of power. The 65W USB port can charge most gaming handhelds at their maximum rate. Even for devices like the ROG Ally X and Lenovo Legion Go, which can handle higher charging rates, this power bank matches the speed of their official power bricks. Typically, power banks in this price range only offer 20-30W of Power Delivery, making this deal exceptional.

Additionally, this power bank is an excellent option for charging your Apple iPhone 16, as ChargerLAB has demonstrated that the maximum charging rate for these devices tops out at around 30W, even for the Pro Max model.
