Solving the “Forgot Apple Watch Charger” Problem
For daily Apple Watch users, running out of battery while away from home or on a business trip is a common inconvenience. Typically, charging an Apple Watch requires a specific charging cable, which can often be forgotten or add to one’s luggage.
EnergyLink addresses this issue by embedding the charging function directly into the Apple Watch band. With a standard USB-C cable and a power source, such as a mobile battery or power adapter, users can charge their Apple Watch whenever needed.

Three Features of EnergyLink
1. Apple Watch Band and Wireless Charger in One
The band features an integrated wireless charging function and a USB-C port. To charge, simply remove the Apple Watch from the band and attach the charging section to the back of the device. It is important to note that the product does not contain an internal battery; a USB-C cable and a power supply device like a mobile battery or power adapter are required for charging.
2. Combining Portability and Wearability
The band is made from soft silicone, designed to comfortably conform to the wrist. Its magnetic lock ensures smooth daily attachment, detachment, and size adjustment. With no need to carry a separate charger, users can enjoy their Apple Watch with greater ease during commutes, outings, travel, and business trips.
3. Compatible with All Apple Watch Case Sizes
EnergyLink offers connector groups for 38-42mm and 44-49mm, supporting a wide range of Apple Watch series. It is available in Black and White, and in M (wrist circumference 130-190mm) and L (wrist circumference 150-210mm) sizes.

Over 50 Million JPY in Cumulative Crowdfunding Sales
The EnergyLink series has achieved over 50 million JPY in cumulative sales through various crowdfunding platforms both domestically and internationally, including Kickstarter, Makuake, and CAMPFIRE. Its functionality, combining a charger and an Apple Watch band, and the convenience of reducing the number of charging accessories to carry, have garnered significant support. BELTIES will offer a total of 100 units for this initial domestic limited sale.
