CIO Mate Joins Amazon Smile Sale with Up to 37 Percent Off, August 28 to September 3

CIO, a gadget maker based in Moriguchi, Osaka, has announced that it will take part in the Amazon Smile Sale running on Amazon from 9:00 on Friday, August 28, 2026 to 23:59 on Thursday, September 3, 2026, discounting products from its CIO Mate sub-brand by up to 37 percent^[1]. The lineup spans power banks with built-in cables, a 67W charger, and a power strip with a retractable cord, centered on PC charging gear.

Sale Overview and Covered Categories

The sale runs for 7 days, from 9:00 on Friday, August 28, 2026 to 23:59 on Thursday, September 3, 2026^[1]. Discounted items are gathered on the CIO Mate store page inside Amazon^[1][2].

According to CIO, the discounts center on PC charging equipment, covering chargers, power banks, cables, and phone stands^[1]. That said, the published per-product discount rates mostly land between 5 percent and 27 percent. The Spiral Cable C to Lightning comes next at 35 percent off, and the headline figure of 37 percent applies only to the C to Lightning silicone cable described below^[1]. CIO states that the list prices and discount rates are rounded figures the company calculated against the suggested retail prices shown on its official site as of August 27, 2026^[1].

CIO Mate is a brand built around accessible pricing and portability, positioning its gear as something you carry daily like an accessory^[1][3]. While the main CIO brand covers higher-end lines such as SMARTCOBY and NovaPort, CIO Mate serves as the more affordable entry tier.

Three Power Banks with Built-in Cables and Magnetic Attachment

Three power banks are included. The 10,000mAh Mate Powerbank003 has a built-in cable and sticks to the back of a phone while charging, priced at 3,280 yen including tax, a 14 percent discount^[1].

For a slimmer option, the 5,000mAh Mate Powerbank 002 attaches to a phone with an internal magnet and charges at up to 15W through its built-in cable. It sells for 2,580 yen including tax, a 16 percent discount^[1].

The steepest cut goes to the 10,000mAh Mate Powerbank 001 at 2,780 yen including tax, 27 percent off^[1]. With two USB-C ports and one USB-A port, it suits charging a phone alongside a second device. CIO says the capacity covers roughly 2 full phone charges^[1].

Chargers Ranging from 20W to 67W

Four chargers are discounted. Charger 001 is a compact model supporting 20W PD fast charging, with a textured finish that resists scratches. It costs 1,780 yen including tax, 9 percent off^[1].

Charger002 delivers 30W, enough for tablets and some laptops in addition to phones, at 2,080 yen including tax, 13 percent off^[1]. The slim Charger003 carries two USB-C ports at 20W and sits flush against a wall outlet, making it easy to pack. It is 1,780 yen including tax, 10 percent off^[1].

Charger004 is the one to watch for laptop users. It pushes up to 67W through USB-C alone, and still manages 45W when the USB-A port is in use, so a laptop and a phone can charge together^[1]. The folding plug helps on the road. The sale price is 3,480 yen including tax, 21 percent off^[1].

The 37 Percent Discount Belongs to a Silicone Cable

Six cables are on offer, and this is where the largest discount comes from. The silicone-jacketed C to Lightning cable comes in 0.15m, 1m, and 2m lengths, priced from 1,180 yen to 1,680 yen including tax, up to 37 percent off^[1]. CIO says it has passed a 30,000-cycle bend test^[1].

The spiral family, which coils itself together magnetically, is also included. The 240W Spiral Cable C to C comes in 1m and 2m at 1,880 yen to 2,280 yen including tax, up to 9 percent off, while the 1m Spiral Cable C to Lightning is 1,780 yen including tax at 35 percent off^[1]. The Spiral Silicone Cable C to C, which combines magnets with a silicone jacket, runs 1,980 yen to 2,180 yen including tax, up to 12 percent off^[1]. The flat version, Flat Spiral Cable CtoC 1m, is 1,880 yen, 5 percent off^[1].

Power Strips and a Magnetic Stand

Power strips are worth a look for desk setups. Mate Tap 001 offers 3 AC outlets plus two USB-C ports and one USB-A port, with USB-C output reaching 20W. Total output is 1,500W, and the sale price is 2,030 yen including tax, 7 percent off^[1].

The higher-end Mate Tap002 keeps the same port layout and adds a retractable USB-C cable that pops out at the press of a button. Total output drops slightly to 1,400W, but you no longer need to bring a separate cable. It sells for 3,580 yen including tax, 10 percent off^[1].

Rounding out the list, the aluminum Magnet Stand, which holds MagSafe-compatible phones or cases with magnets, is 2,680 yen including tax, 12 percent off^[1]. It has no charging function, so it works purely as a stand for setting angle and position^[1].

Summary

CIO is discounting CIO Mate charging gear by up to 37 percent during the Amazon Smile Sale, from 9:00 on August 28 to 23:59 on September 3, 2026. The headline 37 percent applies to the C to Lightning silicone cable, while power banks and chargers mostly sit between 9 percent and 27 percent off. With built-in-cable batteries and a retractable-cord power strip designed to cut down on the cables you carry, it is a practical week for anyone rethinking a commute or desk charging setup.
