CIO, a Japanese company known for its chargers and power banks, has launched the "CIO Mate Powerbank003," a 10,000mAh power bank with a built-in cable[1]. The suggested retail price is 3,830 yen (tax included), and sales began on July 2, 2026, through Amazon.co.jp, the CIO official online store on Rakuten, select electronics retailers, and CIO's own CIO STORE. Built around the concept of "keeping peace of mind close every time you head out," it combines a size that is easy to carry every day with the convenience of charging multiple devices at once.
A 10,000mAh capacity from two 5,000mAh cells
The Powerbank003 pairs two 5,000mAh cells to reach a combined capacity of 10,000mAh[1]. Beyond charging smartphones, the capacity is designed for those moments away from home when you want "just a little more charge" for wireless earbuds or other small devices.
The 10,000mAh class is a popular choice for everyday carry. It avoids being so large that it becomes heavy, while still offering enough headroom to feel reassuring during a commute or a day out.
Built-in cable and two ports handle charging on their own
The defining feature of the Powerbank003 is how it combines its ports with a built-in cable[1]. The body carries both a USB-C port and a USB-A port, and it also includes a built-in USB-C cable. Without carrying a separate cable, this single unit can charge a smartphone and small devices together.
The built-in cable uses a detachable design, so even if it ever breaks you can swap it out and keep using the battery[1]. With many cable-integrated power banks, damage to the built-in cable effectively ends the life of the whole unit. A replaceable structure is a reassuring point for long-term use.
Silicone body and six CIO Mate colors
The body adopts a compact size that fits comfortably in the palm, along with a soft silicone material[1]. Rather than an inorganic gadget, it aims to be something like an accessory that blends naturally into your daily belongings.
The colors follow the soft palette characteristic of the CIO Mate series, offered in six options: Light Black, Natural White, Moss Green, Calm Blue, Airy Purple, and Shell Pink[1].
CIO Mate is a brand born from the wish to "let people feel a future that is a little more exciting than yesterday, in a casual way"[2]. While keeping the core power-bank functions such as fast charging and high output, the brand aims to create products at accessible prices that can be carried like an accessory. The Powerbank003 is positioned as a device that embodies this direction.
Price and availability
The suggested retail price of the CIO Mate Powerbank003 is 3,830 yen (tax included)[1]. Since July 2, 2026, it has been on sale through Amazon.co.jp, the CIO official online store on Rakuten, select electronics retailers, and the CIO STORE. Keeping the price approachable while packing in practical touches such as the built-in cable and two-port layout makes it an easy pick for an everyday power bank.
Summary
The CIO Mate Powerbank003 is a power bank that combines a 10,000mAh total capacity from two 5,000mAh cells with a detachable built-in USB-C cable and both USB-C and USB-A ports. With its soft silicone body in six colors and an approachable price of 3,830 yen (tax included), it balances the convenience of not needing a separate cable with the reassurance of being able to replace that cable if it breaks, making it a solid companion for everyday carry.
