Kuxiu S3 Power Bank Boosts Capacity and Charging Speed

Tech enthusiasts looking for a safer, longer-lasting portable charger have a new option. Kuxiu’s latest S3 power bank doubles the capacity of its predecessor, offers faster wireless charging, and includes handy upgrades like a kickstand and a built-in USB-C cable. The new design promises both convenience and durability for smartphone users on the go.

Bigger Battery for Longer Smartphone Use

The S3 now features a 10,000mAh capacity—up from 5,000mAh in the S2—enough to nearly double the battery life of most iPhones, depending on the model. The semi-solid state battery continues Kuxiu’s use of a safer, solid-liquid mixed electrolyte that extends battery longevity while reducing risk compared with traditional lithium-ion cells.

Faster Wireless Charging with Qi2.2

Wireless charging gets a significant upgrade with Qi2.2 compatibility. The S3 can deliver up to 25W wirelessly, making it easier to top up smartphones quickly without the hassle of cables. Kuxiu has also added stronger N52 magnets—18 in total—to keep the power bank securely attached during charging.

Handy Display and Kickstand

For added user convenience, the S3 includes a small display showing remaining battery and charging status. A built-in kickstand allows for hands-free device use while charging, perfect for watching videos or video calls without propping your phone awkwardly.

Built-In USB-C Cable for On-the-Go Charging

Another notable feature is the integrated USB-C cable, which supports power delivery of up to 35W. This means the S3 can charge other devices efficiently, from smartphones to tablets and even some laptops, without needing extra cords.

Slightly Heavier, But More Practical

Thanks to the larger battery and additional features, the S3 is heavier than its predecessor, weighing in at over 245g. Despite the extra weight, Kuxiu’s design tweaks—including stronger magnets—ensure stability and prevent accidental drops during wireless charging.

Ideal Upgrade for Gadget Lovers

Overall, the Kuxiu S3 blends enhanced capacity, faster charging, and practical features like a kickstand and display, making it a versatile choice for tech users. Whether you’re commuting, traveling, or working from home, it addresses many of the small annoyances of portable charging.

Availability and Pricing

While Kuxiu hasn’t yet revealed pricing details for the S3, the company has confirmed it will roll out shortly in select markets. Given the upgrades over the S2, it’s expected to appeal to anyone looking for a safer, more powerful portable battery with smart features.
