This is one of the smallest 20,000mAh power banks I've seen, measuring 4.3" long and 2.8" wide (it's pretty chunky though at 1.1" thick) and weighing in at about 11 ounces. The ample 20,000mAh (74Whr) capacity can charge any gaming handheld PC, including ones with bigger 80Whr batteries like the Xbox Ally X, from 0% to 100% (or close to it). It can recharge smaller capacity gaming handhelds like the Nintendo Switch 2 or Steam Deck multiple times on a single charge.
The Iniu power bank has three total ports: one 65W USB Type-C port, one 36W USB Type-C port, and one 18W USB Type-A port. The 65W output can charge any gaming handheld even while you're playing on it at the same time. Some models like the Asus ROG Ally and Legion Go 2 can accept up to 100W of charging, but you don't necessarily want to max out the rate even if you can. Asus and Lenovo package them with conservative 65W chargers to reduce stress on the battery.
