Kuxiu’s solid-state power bank now has more capacity and faster wireless charging
- The Kuxiu S3 solid-state power bank now has twice the capacity of its predecessor at 10,000mAh, offering nearly double an iPhone’s battery life.
- The new power bank is Qi2.2-compatible, allowing for faster wireless charging up to 25W and a built-in cable for charging other devices through a USB-C port with up to 35W power delivery.
- The S3 features an integrated kickstand for hands-free smartphone use, a small display showing its remaining capacity and charging status, and increased safety measures thanks to more N52 magnets.
- Despite being more expensive than traditional wireless power banks, the Kuxiu S3 is expected to have a longer lifespan due to its solid-state battery technology, which should only see an 80% capacity drop after 1,000 charging cycles.
- The power bank is currently available for $149.98 (temporarily discounted to $68.99) and offers improved safety features and faster wireless charging compared to its predecessor.
Seven months after launching its first semi-solid state battery that used a safer and longer-lasting solid-liquid mixed electrolyte, Kuxiu is introducing a new version with some welcome upgrades. The S3 has twice the capacity of the S2 at 10,000mAh – 5,000mAh at 7.7V (38.5Wh) – that the company says is enough to nearly double an iPhone’s battery life, but that will vary depending on the model.
The Kuxiu S3 is also Qi2.2-compatible so it can wirelessly charge compatible devices at up to 25W. Its larger battery means it’s over 100g heavier than the 145g S2, but Kuxiu has increased the number of N52 magnets it uses from 16 to 18 to help reduce the risk of the power bank being accidentally knocked off your phone. There’s an integrated kickstand now on the back, a small display showing its remaining capacity and charging status, and a built-in cable for charging other devices through a USB-C port with power delivery rated at up to 35W.
As with the previous model, the S3 is more expensive than traditional wireless power banks offering similar capacity, charging rates, and features, but the cost of the technology should drop over time as manufacturing improves and increases. It’s available now for $149.98, but temporarily discounted to $68.99. If that seems hard to stomach, remember that while the capacity of most power banks will start to degrade after 300 to 500 cycles, the S3 should only see a drop to about 80 percent capacity after 1,000 charging cycles. It will have a much longer lifespan, and is less at risk from issues like fire and thermal runaway should you accidentally drop it.
