CIO, the Japanese company known for its chargers and power banks, has announced the products from its sub-brand CIO Mate that will be discounted during Amazon Prime Day[1]. The Mate Powerbank003, a 10,000mAh power bank with a built-in cable, makes its first-ever sale appearance at 2,980 yen (22% off), while chargers, power strips, and cables are offered at up to 25% off — with some Lightning cables discounted by as much as 47%.

Early Sale Plus Main Sale Adds Up to Seven Days

Amazon Prime Day runs from 0:00 on July 10 to 23:59 on July 13, 2026[1]. The CIO Mate items have already been discounted since the Prime Day Early Sale, which runs from 0:00 on July 7 to 23:59 on July 9, and the same sale prices apply across both periods. Note that the sale ends as soon as stock runs out.

The published discount rates are calculated against the manufacturer's suggested retail prices listed on CIO's official website as of July 7, 2026[1].

First Sale for the Mate Powerbank003 at 2,980 Yen

The highlight of this sale is the Mate Powerbank003, appearing in a sale for the first time[1]. It is a 10,000mAh power bank with a built-in cable that attaches directly to your smartphone while charging, priced at 2,980 yen (tax included), 22% off. The product just launched on July 2, 2026 at a regular price of 3,830 yen (tax included)[2], so it is reaching this accessible price only about a week after release.

Alongside it, the Mate Powerbank 002 — a slim 5,000mAh model with built-in magnets that clings to your phone and charges via a built-in cable at up to 15W — is offered at 2,580 yen (tax included), 16% off[1].

Chargers Range From One of the World's Smallest 20W Models to a 67W Dual-Port Model

Four charger models are included in the sale[1]. For smartphones, the Charger 001 — claimed to be among the smallest in the world (as of July 7, 2026, according to CIO) with 20W PD fast charging and a scratch-resistant textured finish — is 1,640 yen (tax included), 16% off. If you also want to charge tablets or some laptops, the 30W Charger002 is 1,980 yen (tax included), 18% off.

If you prefer a slim design, the Charger003 with two USB-C ports and 20W output is 1,650 yen (tax included), 17% off; its low-profile shape sits flush against the wall outlet and travels well. The most powerful of the four is the Charger004, delivering up to 67W over USB-C alone — enough for laptop charging — and 45W even when the USB-A port is used simultaneously. With a foldable plug for portability, it is 3,280 yen (tax included), 25% off.

Cables at Up to 47% Off, Plus Power Strips and a Stand

Among cables, the sale centers on CIO's magnetically self-organizing spiral series[1]. The newly introduced flat version, the Flat Spiral Cable CtoC (1m), is 1,680 yen at 15% off; the supple silicone-jacketed Silicone Cable C to C (0.15m–2m) is 1,080–1,600 yen (tax included) at up to 22% off. For iPhone users, the Silicone Cable C to Lightning is 1,000–1,400 yen (tax included) at up to 47% off — the deepest discount in this sale. The magnetic Spiral Cable is up to 25% off in its C to C version, and 45% off in the Lightning version.

In addition, the Mate Tap 001 power strip with three AC outlets, two USB-C ports, and one USB-A port is 1,930 yen (tax included) at 12% off, and the Mate Tap002, which adds a retractable built-in USB-C cable, is 3,280 yen (tax included) at 17% off. The aluminum Magnet Stand, which holds MagSafe-compatible smartphones magnetically (no charging function), is also available at 2,380 yen (tax included), 22% off[1].

Summary

CIO Mate is a brand built around gadgets you can carry like accessories, born from the idea of "feeling a future slightly more exciting than yesterday, casually"[1]. This Prime Day brings the just-released Mate Powerbank003 to its first sale at 2,980 yen (22% off), along with discounts across chargers, cables, and power strips. Sale prices last until 23:59 on July 13, but only while stock lasts, so if something catches your eye, checking early is recommended.
