About O-Ring

O-Ring is a concept for an ultra-slim magnetic power accessory designed to attach to the back of a compatible smartphone and deliver supplemental power while you keep using your device. Where cables restrict movement, charging pads demand a surface, and traditional power banks add bulk to your everyday carry, O-Ring is being designed to provide a small, targeted boost of backup power without the tether.

The accessory is being developed around magnetic attachment for compatible iPhones, with Qi2 and Android compatibility planned but not yet confirmed. A proposed thickness of 4.8 millimeters and a target capacity of roughly 600–800 mAh are design goals, not validated specifications; final dimensions, capacity, and supported devices will be confirmed before launch.

O-Ring is for people who move — commuters, travelers, creators, and anyone whose phone rarely makes it through a long day. It is not meant to replace a wall charger or a high-capacity bank, but to offer a discreet, carry-anywhere top-up that fits the way you already use your phone.

O-Ring is built by an independent hardware team. The product shown on this site is a concept in development, not a finished product available for immediate delivery. Pricing, launch timing, and production are tentative. Our $1 VIP reservation is a refundable early-access deposit that qualifies you for planned launch pricing of $29 versus a proposed $49 retail price; it is not a purchase, and production is not guaranteed.
