Get a 20,000mAh 45W Power Bank With Integrated USB Cable for Under $20 Ahead of Black Friday

The 20,000mAh capacity can fully recharge most gaming handhelds

This CUKTECH power bank boasts a generous 20,000mAh, or 74Whr battery capacity. If you factor in 80% power efficiency, here are the approximate number of times you can fully recharge each gaming handheld or iPhone model:

• Nintendo Switch 2 (18Whr) about 3.3 times
• Steam Deck (40-50Whr) about 1.2-1.5 times
• ROG Xbox Ally (60Whr) about 1 times
• ROG Xbox Ally X/X20 (80Whr) about 0.7 times
• Lenovo Legion Go 2 (74Whr) about 0.8 times
• Apple iPhone 17 (14Whr) about 4.2 times
• Apple iPhone 17 Pro Max (20Whr) about 3 times

Can fast charge your Nintendo Switch 2, Steam Deck, and Apple iPhone 18 Pro

The power bank has three total ports: one integrated 45W USB-C cable, one 45W USB-C port, and one 18W USB-A port. If you use two or three ports simultaneously, the power outputer throttles down to 15W per port. The 45W of Power Delivery is enough to charge the Nintendo Switch 2 (20W) and Steam Deck (35W) even while you’re playing games at the same time. It will also fast charge the Apple iPhone 18 Pro (30W). The built-in cable is a popular feature because you no longer have to bring along your own USB Type-C cable.
