What is Semi-Solid State Battery Technology? 

Conventional lithium-ion batteries use liquid electrolytes, which can pose leakage/oxidation risks; if the casing is compromised and the liquid is exposed to oxygen, it may lead to ignition or explosion.

CIO’s semi-solid-state cells engineer the electrolyte into a stable “clay-like” / “sponge-like” structure, reducing liquid content to ~5%.

Even in extreme tests including nail penetration, the cells are described as highly resistant to ignition or smoke.

Beyond Safety

Industry-Leading 8.7mm Thickness

8.7mm thick, 121g. The thinnest Qi2 power bank in its class.

Featuring a NovaCore C2 internal expansion buffer designed to manage natural battery swelling (limited to just 8% after 300 cycles) without creating a bulge.

True Pass-Through & Dual Charging 

Charge your phone and the power bank with one cable. 

Once the internal battery is full, power is diverted directly to your phone, bypassing the battery cells to reduce the heat-related degradation common in standard pass-through systems.

Use it as your permanent bedside wireless charger every night without worrying about wearing out the power bank's battery lifespan .

Fast Charging, Wired and Wireless

Via Cable: The 20W USB-C port charges an iPhone to 50% in just 30 minutes.

Via Wireless: Toggle the output between 7.5W and 15W to balance speed and heat.

Advanced Cooling

NovaSafety S2 firmware actively regulates power output to keep surface temperatures around 42°C (107°F).

 Combined with an aluminum heat-dissipation casing, it delivers more effective cooling than typical plastic alternatives, even during fast charging.

"Tech-Luxe" Aesthetics 

The matte-finish aluminum alloy resists scratches, stays fingerprint-free, and features a rounded "R-edge" design for a smooth, ergonomic grip. 

The Liquid Silicone Rubber (LSR) charging surface helps prevent the power bank from scratching your smartphone’s glass back.

2.5x Longer Lifespan

CIO’s semi-solid cells boast an extraordinary lifespan of approximately 2,000 cycles.  (~2.5× vs ~800 cycles for standard lithium).

Although the initial manufacturing cost is higher, the long-term durability is 2 to 3 times greater than traditional products
