INIU 20,000mAh 65W USB Power Bank

Available at Amazon – Use promo code WN9GQJRA
This INIU power bank features a large 20,000mAh (74Whr) battery capacity. Accounting for an average 80% efficiency rate, you can expect approximately:
- Nintendo Switch (16Whr) – Recharge about 3.7 times
- Steam Deck (40Whr) – Recharge about 1.9 times
- Asus ROG Ally (40Whr) – Recharge about 1.9 times
- Asus ROG Ally X (80Whr) – Recharge around 1 full time
- Lenovo Legion Go (50Whr) – Recharge about 1.5 times
The power bank offers three output ports: a 65W USB Type-C port, a 36W USB Type-C port, and a USB Type-A port capable of up to 18W charging. The 65W USB port delivers fast charging speeds suitable for most gaming handhelds. For devices that support higher wattage, like the Asus ROG Ally X and Lenovo Legion Go, it matches the charging speed of the original power adapter. Considering most power banks in this price range only support up to 20-30W of Power Delivery, this is definitely a standout offer.
Additionally, this power bank is ideal for charging Apple’s iPhone 16 lineup. According to ChargerLAB, the maximum charging speed tops out at around 30W—even for the iPhone 16 Pro Max—making the 65W output more than sufficient.
