The battery in most smart glasses lasts two to four hours of active use. That sounds adequate until you're on a long flight, a full day of outdoor shooting, or a conference where you need your glasses on for eight hours. When the glasses die, you're done — there's no quick-swap battery option. The SGG LOOP is a wearable power bank that sits around your neck and keeps your smart glasses charged continuously through a short cable.
The battery problem
Smart glasses pack their battery into a tiny frame. There's only so much capacity you can fit alongside cameras, speakers, processors, and display components. The result: 2–4 hours of active use is typical, and charging requires taking the glasses off and plugging them in. For daily commute-and-office use, this is manageable — you charge at your desk. For extended use scenarios, it's a hard limit on how long you can stay in the experience.
LOOP turns that hard limit into a soft one. The neck-worn power bank connects to your glasses via a short cable and provides continuous power. Your glasses stay on, stay charged, and your session length is limited only by the LOOP's own battery — which is measured in multiple full recharges of the glasses, not hours.
Wearing it
LOOP sits around the back of your neck and rests on your shoulders, similar to a pair of neckband earbuds. The weight is distributed across both sides so it doesn't pull to one side. A short cable runs from the band to your glasses — short enough to stay out of the way but long enough to allow normal head movement.
The form factor is deliberate. A pocket power bank with a long cable running up to your face is awkward and looks terrible. A neck-worn unit keeps the cable short, the weight centered, and the appearance minimal. It's not invisible — people can see the band — but it's far more practical than the alternative.
Who actually needs this
- Travelers. Flights, trains, long car rides — any situation where you want your glasses on for 4+ hours without a charging break. LOOP is the only way to get there on most smart glasses.
- Content creators. If you shoot first-person video on Ray-Ban Meta, the camera burns through the battery fast. LOOP keeps recording going through a full shoot.
- Conference and event attendees. All-day smart glasses use at a conference or trade show without hunting for outlets.
- Display glasses users in long sessions. XREAL, Rokid, and VITURE all drain faster when the display is active. LOOP extends movie marathons, productivity sessions, or gaming without interruption.
Compatibility
LOOP works with any smart glasses that charge via USB-C. This includes most modern smart glasses from Rokid, XREAL, VITURE, and RayNeo. Ray-Ban Meta uses a proprietary charging case rather than direct cable charging, so LOOP is not directly compatible with Meta frames — though it can charge the Meta case if you carry it in your pocket.
The honest take
LOOP solves a hard problem — battery life on smart glasses — with a practical tradeoff: you're wearing an additional device around your neck. For short daily use, you don't need it. For extended sessions where battery death would end your experience, it's the only real solution. At $59.99, it's priced as a serious tool for serious users, and that's exactly what it is. If you've ever had your smart glasses die at the worst possible moment, you already know whether you need this.
