4

The AsperX is a candy bar style power bank with a unibody aluminum shell that gives it a premium feel and helps with heat dissipation. There are a total of three outputs: one 2ft 100W USB-C retractable cable, one 100W USB-C port, and one 30W USB-A port. The total output capacity is 165W, so you can run charge two USB-C devices at 100W and 65W respectively.

The 100W charging input can fast charge gaming handhelds and laptops

The 100W output will charge all gaming handheld PCs at their fastest charging rate, including the Nintendo Switch 2, Steam Deck, and even power hungry models like the Asus ROG Xbox Ally X and and Legion Go 2. It can also fast charge many non-gaming laptops like the MacBook Air, which maxes out at 70W.

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

This AsperX 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 (80Whr) about 0.7 times
• Lenovo Legion Go S (55Whr) about 1 time
• Apple iPhone 17 (14Whr) about 4.2 times
• Apple iPhone 17 Pro Max (20Whr) about 3 times

You don’t need to worry about being stopped at airports. The 20,000mAh 74Whr capacity is well below TSA’s 27,000mAh/100Whr carry-on limit, so you are safely in the clear.
