Iniu 25,000mAh 100W Power Bank Hits Year's Lowest Price

I've shared many power bank deals, but today's offer stands out as arguably the best I've encountered this year. Amazon has the high-capacity, high-output Iniu 25,000mAh 100W power bank available for just $27.49 after applying coupon code "IP3GGX8A". This power bank is perfect for long flights or trips when you may not have access to an outlet for extended periods. It delivers enough power to charge almost any smartphone or gaming handheld—including the Asus ROG Ally X and the upcoming Lenovo Legion Go 2—even while you're gaming, along with most non-gaming laptops.

A 25,000mAh power bank isn't exactly small, but this model is surprisingly compact, measuring 6"x3"x1.3" and weighing around one pound. It includes three ports: one USB-C port with 100W output, a second USB-C port offering 45W, and one USB-A port with 18W output. Keep in mind that the maximum total output is 100W. While the individual port capacities total 163W, the power bank will only deliver up to 100W across all three ports simultaneously.

Its 25,000mAh capacity is ideal for powerful gaming handhelds

This Iniu power bank features a sizable 25,000mAh (92.5Wh) battery capacity. Assuming 80% power efficiency, here’s approximately how many full charges you can expect for popular gaming handhelds and iPhones:

Nintendo Switch 2 (18Wh): around 4.1 charges Nintendo Switch (16Wh): around 4.6 charges Steam Deck or Asus ROG Ally (40Wh): roughly 1.8 charges Asus ROG Ally X or Legion Go 2 (74-80Wh): approximately 0.9 charges Lenovo Legion Go/Go S (50-55Wh): about 1.4 charges

This clearly illustrates why a 10,000mAh power bank falls short for more demanding handheld devices.

With 100W output, it fast-charges nearly all phones and gaming handhelds

The 100W output exceeds what's typical for chargers in this price range. It provides sufficient power to charge every gaming handheld on the market—even during gameplay. This includes the latest models like the Asus ROG Ally X and Legion Go 2 / Go S, which support up to 100W charging. It also works with most non-gaming laptops that support USB-C Power Delivery, a feature common in newer laptops.

This power bank is approved for air travel

The 25,000mAh (92.5Wh) capacity stays just under the TSA carry-on limit of 27,000mAh (100Wh). Although its substantial size might attract attention (I was once stopped with a 24,000mAh model), you should have no trouble getting it through security.
