Charger maker CIO Inc. has released the "CIO Mate Powerbank002," a power bank with a built-in charging cable. Its main appeal is convenience: it attaches magnetically to the back of a smartphone, and you can charge simply by pulling out the built-in USB-C cable. It has a 5,000 mAh capacity, weighs about 120 grams, and carries a suggested retail price of 3,080 yen (tax included). Sales began with pre-orders on Amazon on November 21, 2025[1].
A "Built-In" Design That Saves You From Carrying a Cable
The central idea behind this power bank is that the charging cable is integrated into the body. A typical power bank requires you to carry a separate USB cable. Many people have experienced forgetting just the cable while out, leaving them unable to charge despite having the battery on hand. The CIO Mate Powerbank002 has a USB-C cable with up to 15 W output built into the body, so you can quickly pull it out and use it whenever needed[1].
The way it attaches to a smartphone is also distinctive. If your smartphone or case supports magnetic attachment, the unit sticks firmly to the back. Because you can keep the battery stacked on the smartphone and insert the built-in cable into the charging port at the bottom, the structure is easy to handle with one hand even while charging[1].
The side of the unit also has a USB-C port (up to 15 W output). Together, the built-in cable and the side port support a combined maximum of 15 W of charging[1]. This covers situations where you want to use your own cable or charge a device the built-in cable cannot reach.
5,000 mAh at About 120 Grams, With Battery Level Shown on a Digital Display
The capacity is 5,000 mAh, which is enough to top up a smartphone while out and about. At about 120 grams, it is light, and its compact design fits easily into a bag or pouch[1]. Since this product is designed to be carried attached to a smartphone, its light weight and slim profile matter in practical use.
Features that improve usability are also included. The unit uses a digital display that shows the remaining charge in increments of 1 percent, so you can tell at a glance when it is time to recharge before running out[1]. Compared with products that only have a rough lamp indicator, the ability to plan your usage is reassuring.
The surface of the unit has a textured finish that fits comfortably in the hand. According to CIO, this finish makes the unit resistant to scratches in everyday use and provides a comfortable feel[1]. For a product carried daily alongside a smartphone, a finish that helps maintain its appearance is a welcome consideration.
Six Color Options and the Fun of Matching the Mate Series
The colors available are Light Black, Natural White, Moss Green, Shell Pink, Calm Blue, and Airy Purple, for a total of six[1]. Charging gadgets tend to center on black and white, so a wide lineup of six colors is attractive for those who want to match the color of their smartphone or case.
CIO offers the "Mate" series, which includes chargers and cables, and the CIO Mate Powerbank002 is part of it. By matching colors within the series, you can give your belongings a unified look[1].
The suggested retail price is 3,080 yen (tax included). Pre-orders began on Amazon, and the product is subsequently being carried at some electronics retailers and at the CIO STORE direct shops[1]. During the "Amazon Black Friday" event at launch, it was sold for 2,580 yen[1]. Third-party reviews have also highlighted its light weight and wide range of colors as easy-to-use points[2].
