TOKYO, October 6 — MATECH has launched two new mobile battery products that integrate USB-C connectors directly into their design, aiming to simplify charging for users on the move. The announcement came via an ASCII.jp article published on October 6, 2026, which was AI-translated from Japanese. On October 5, 2026, MATECH unveiled the ‘PowerNano 5000’ and the ‘PowerNano Watch 5000,’ both featuring a built-in USB-C port that plugs straight into a smartphone for charging without extra cables.
Each battery holds a 5,000mAh capacity and supports fast charging up to 22.5W. They also include pass-through charging, allowing users to charge their devices while simultaneously recharging the battery pack itself.
The PowerNano 5000 is priced at 3,990 yen (approximately US$27), and the PowerNano Watch 5000 costs 4,590 yen (approximately US$31), based on current exchange rates. Both are available for purchase on MATECH’s official store on Amazon.co.jp. A limited-time 20% point back campaign is running on the Amazon.co.jp store until October 11, 2026, offering incentives for early buyers.
The PowerNano 5000 measures approximately 78mm (W) x 37.4mm (H) x 28.6mm (D) and weighs about 108g. It supports simultaneous charging of up to three devices.
The PowerNano Watch 5000 weighs approximately 113g and can charge up to four devices at once. A distinctive feature of the PowerNano Watch 5000 is its dedicated wireless charging pad for Apple Watch, enabling users to charge their smartwatch without removing the band. It also includes a rear stand for convenient video viewing or video calls.
Both models are available in silver and black color options. MATECH positioned these products as compact charging solutions suitable for daily commutes, school, or travel. The USB-C integrated design eliminates the need to carry separate charging cables, aiming to reduce clutter in users’ bags.
No further technical specifications, manufacturing details, or corporate background about MATECH were provided in the source material. Looking ahead, users will be watching how these cable-free charging solutions perform in real-world use and whether similar integrated designs gain traction across the portable power market.
