[About SMARTCOBY Ex04 Wireless2.2 CABLE SS5K]
The Ex04 being sold this time is a mobile battery equipped with a "semi-solid state battery cell."
In recent years, the term "semi-solid state battery" has become commonly used, but there is currently no official standard or industry-wide definition. CIO defines "semi-solid state battery" based on cell specifications, test conditions, and actual measurement data, and designs products after confirming their performance and safety.
While positioned as the successor to the Ex01, the Ex04 is a product equipped with the latest technology. It supports Qi2.2 wireless charging (up to 25W) and wired output (up to 22W), allowing for speedy smartphone charging. With a capacity of 5,000mAh, it achieves a compact design of approximately 151g and a thickness of about 14mm.
