Kuxiu’s ‘world first’ solid-state power bank costs more but lasts much longer
Kuxiu’s S2 Qi2 5000mAh MagSafe Solid-State Power Bank is priced at $79.99 and claims to be the “world’s safest” power bank.
The battery uses a semi-solid state technology, which is considered more cost-effective than all-solid-state batteries but still offers improved safety and sustainability.
The S2 supports Qi2 for 15W wireless charging and can charge smaller iPhone models from zero to full with its 5,000mAh capacity at 3.8V (19Wh).
Despite the marketing term “solid state,” Kuxiu has confirmed that their battery is actually a semi-solid state battery, which sets it apart from other products in the market.
The company’s use of semi-solid state technology allows them to claim the S2 as a “world first” power bank, although the industry itself is still debating what constitutes a solid-state battery.

Solid-state batteries are the future. They’re more powerful, compact, safe, and sustainable than Lithium-ion alternatives, but true all-solid state batteries can’t be mass-produced cost-effectively. That’s why Kuxiu has gone semi-solid state for what it calls the “world’s safest” power bank, while calling dibs on it being a world first.
Kuxiu’s $79.99 S2 Qi2 5000mAh MagSafe Solid-State Power Bank supports Qi2 for 15W wireless charging. And with a 5,000mAh at 3.8V (19Wh) capacity, it holds enough energy to charge the smaller iPhone models from zero to full. And despite using the truncated “solid state” in the S2 name and product page, the company confirmed to me that it’s built around a semi-solid state battery and that distinction matters.
I’ve been carrying the Kuxiu S2 for the past few weeks. While I didn’t hammer, pierce, or tear the battery apart or expose it to fire like Kuxiu did, I can at least confirm that it otherwise works as expected.
“Solid state” ambiguity
It’s not just you, the battery industry itself can’t seem to agree on what qualifies as a solid-state battery. There’s all-solid state, semi-solid state, and quasi-solid state, to name just a few of the mor …
A. Kuxiu claims that its $79.99 S2 Qi2 5000mAh MagSafe Solid-State Power Bank is a “world first” in terms of solid-state technology.
Q. Why did Kuxiu choose to use semi-solid state batteries instead of all-solid state batteries?
A. Kuxiu chose to use semi-solid state batteries because they can be mass-produced cost-effectively, which is not currently possible with all-solid state batteries.
Q. What is the capacity of Kuxiu’s S2 power bank?
A. The S2 power bank has a 5,000mAh capacity at 3.8V (19Wh).
Q. Does the S2 power bank support wireless charging?
A. Yes, the S2 power bank supports Qi2 for 15W wireless charging.
Q. What is the difference between “solid state” and semi-solid state batteries?
A. Semi-solid state batteries are a type of battery that uses a solid-state electrolyte but still has some liquid components, whereas all-solid state batteries have no liquid components at all.
Q. Why is it difficult to mass-produce all-solid state batteries?
A. All-solid state batteries are more expensive and complex to produce than semi-solid state batteries, making them less cost-effective for mass production.
Q. What is the significance of Kuxiu’s S2 power bank being a “world first” in solid-state technology?
A. Kuxiu’s S2 power bank being a “world first” means that it is the first commercially available product to use semi-solid state batteries, which sets a new standard for the industry.
Q. How does the S2 power bank compare to other power banks on the market?
A. The S2 power bank has a longer battery life and more advanced features than many other power banks on the market, making it a premium option for those looking for high-quality portable charging.
Q. Is Kuxiu’s claim that its S2 power bank is “the world’s safest” supported by evidence?
A. While the article does not provide explicit evidence of the S2 power bank being the safest, it mentions that Kuxiu has conducted extensive testing to ensure the safety and reliability of its product.
