Power That Keeps Up With You

Meet the SMARTCOBY Ex04 — a slim, intelligent 5000mAh power bank engineered for the way you actually live. Qi2.2 wireless charging, a built-in USB-C cable, and a semi-solid battery cell that prioritizes both performance and peace of mind. Everything you need. Nothing you don't.

Qi2.2 Wireless Charging — Up to 25W

Built on the magnetic Qi2 standard, the Ex04 delivers up to 25W wireless charging for Qi2.2-compatible devices (iPhone 17 series, Galaxy S26, Pixel 10, and more), and up to 15W for Qi2-compatible devices. Just place your phone and charge — no cables, no fuss. Prefer a cooler charge? Hold the button for 5 seconds to switch to 7.5W Safety Mode.

※ Simultaneous wireless and wired charging is not supported. When charging two devices at once, connect one to the built-in cable and one to the USB-C port (combined output: max 15W). Qi2-incompatible devices will charge via standard Qi.

Semi-Solid Battery Cell — Built for Everyday Confidence

The Ex04 uses a semi-solid battery cell designed with both structural integrity and intelligent control in mind. It's been tested against heat, short circuits, pressure, and drops — and features automatic output control that monitors internal temperature in real time to prevent excessive heat buildup. You can't see it working, but it's always on.

※ "Semi-solid" is defined by CIO's own standards, as no universal definition currently exists.

Built-In USB-C Cable — One Less Thing to Carry

A ~21cm USB-C cable is integrated directly into the body, supporting up to 20W input/output. Charge your phone, earbuds, or even the power bank itself — without ever digging through your bag. The cable is detachable, so if it ever wears out, it's replaceable with any standard USB-C cable.

Slim, Light, and Ready to Go

At just 100 × 70 × 14mm and approximately 151g, the Ex04 slips into a pocket, sacoche, or bag without weighing you down. A rubber-coated surface protects your phone's back from scratches during magnetic attachment, while the thin profile makes it easy to hold alongside your device.

5000mAh — The Right Amount of Power

Enough to charge an iPhone 17 Pro approximately 0.77× wired or 0.66× wirelessly, and an iPhone 16 Pro approximately 0.88× wired or 0.8× wirelessly. Perfect for topping up on the commute or during a long day out. Battery level is displayed in 1% increments on the digital screen — no guessing.

Full Pass-Through Charging

Charge the Ex04 via USB-C while simultaneously charging your device — wired or wirelessly. Once your device is fully charged, the Ex04 resumes charging itself. And once the Ex04 reaches 100%, it cuts power from the battery cell and routes power directly to your device. Use it as a permanent wireless charging pad at your desk, and it'll always be ready when you head out the door.

Core-Level Safety Design

Beyond the semi-solid cell itself, CIO's internal design standards cover expansion clearance, cell partitioning, flame resistance, and heat dissipation. The core cell temperature is designed to stay within 55°C. Real-time thermal monitoring and automatic output control are managed entirely by CIO's proprietary firmware — invisible, but always working to keep your charge safe.
