Transnovo SnapCharge

Charging Ray-Ban Meta smart glasses normally means taking them off and setting them into their case. That's a real limitation for people who rely on the glasses away from home. Transnovo SnapCharge takes a different approach: it attaches to the glasses so they can charge while still being worn.

Charging without the interruption

The maker's central claim is wear-while-charging operation. Instead of losing the glasses during a top-up, the wearer could keep listening to music on a walk or keep information on display in a meeting while the battery is replenished.

What the maker claims

• 1600mAh of additional power
• Up to 24 hours of extended use
• 6 charges for models such as Meta Wayfarer and Skyler
• A dual battery swap system: one battery charges while the other is in use
• A weight of 20g
• A multi-function protection system and smart temperature control, intended to guard against overcharging and overheating

The dual-battery design is meant to bring downtime close to zero. When one pack runs low, it can be swapped for the other so the glasses stay in use.

At 20g, the attachment is meant to preserve the light feel of the glasses during extended wear. The maker says its protection and temperature-control features keep charging safe and reliable.

Looking ahead

According to the source, the development team plans further improvements. Possibilities mentioned include higher-capacity batteries, faster charging and support for other smart glasses models. None of these is presented as confirmed.
