CIO has begun selling a limited-run model called the SMARTCOBY SLIM II Wireless2.0 8K Ikefukurou Edition, decorated with the Ikefukurou owl that has long been embraced as a symbol of Ikebukuro. The release marks the opening of Yodobashi Camera Multimedia Ikebukuro, and only 500 units were produced. The base product is a slim Qi2 wireless power bank, and the price is 7,680 yen including tax[1].

Turning an Ikebukuro Landmark into Line Art on the Back Panel

The Ikefukurou is a figure familiar to both locals and visitors as a symbol of Ikebukuro. This limited model renders it in a line-art style across the rear panel of the battery. According to CIO, the design was shaped from customer survey responses into something that conveys the character of Ikebukuro[1].

Two colors are offered, black and white. Sales are limited to the CIO store on basement floor 1 of Yodobashi Camera Multimedia Ikebukuro, and the run ends once the 500 units are gone. It sits comfortably between a souvenir and a charging accessory people will actually carry every day[1].

About 12mm Thick, Qi2 Support, and Roughly One Phone Charge

The base model, the SMARTCOBY SLIM II Wireless2.0 8K, is one of CIO's slim wireless batteries. It attaches magnetically to MagSafe-compatible iPhones and delivers up to 15W of wireless charging under the Qi2 standard. Capacity is 8,000mAh, enough for roughly one full smartphone charge[1][2].

The body measures about 12mm thick and weighs about 162g, so it fits in a pocket or a small pouch. CIO uses an aluminum alloy shell for heat dissipation and rigidity, and finishes the magnetic contact surface in liquid silicone to balance grip and durability[1][2].

Input charging runs at 20W, reaching a full charge in roughly 120 minutes with a fast charger. Full pass-through charging is supported, so the battery can charge a connected device while it is itself being charged. Once the battery reaches full charge, it automatically switches to a DC circuit dedicated to device charging. The goal is to limit degradation of the internal cells, which matters for anyone who tends to leave the battery plugged in on a desk[1].

Choosing Between Heat and Speed with Two Output Modes

In slim wireless batteries, charging speed, thickness, and heat all pull against one another. CIO's answer was to provide two output modes[1].

Safety Mode keeps temperatures down, while High Performance Mode prioritizes charging speed. Safety Mode suits summer use beside a bed or inside a pocket, and High Performance Mode fits the moment before heading out the door. Rather than committing the product to one philosophy, CIO hands the decision to the user[1].

CIO was founded in 2017 and is based in Moriguchi, Osaka, building its own chargers and power banks. A limited model tied to a local landmark is an easy fit for a retailer's store opening, and it gives gadget enthusiasts a reason to stop by[1].

Summary

The SMARTCOBY SLIM II Wireless2.0 8K Ikefukurou Edition wraps a practical package, Qi2 support, roughly 12mm thickness, and 8,000mAh, in a design tied to a symbol of Ikebukuro, limited to 500 units. It costs 7,680 yen including tax and is sold only at the CIO store on basement floor 1 of Yodobashi Camera Multimedia Ikebukuro. Performance matches the base model, so the decision comes down to whether the design appeals.
