The RayNeo X3 Pro carries a 245 mAh battery. That one cell has to run everything else on the glasses: two full-color micro-LED projectors, a Snapdragon AR1 Gen 1 chip, Wi-Fi 6, two cameras and Google's Gemini assistant. RayNeo's product page gives no runtime at all.
The X3 Pro is RayNeo's standalone AR model, a step above its display-free iO glasses. The Air series is a separate line of screens for watching video from a phone or console. Its closest rival is the Meta Ray-Ban Display, which has a screen in one lens only.
Nobody at this site has worn a pair, and we have no independent measurement of battery or brightness. This review rests on RayNeo's specifications, its FAQ and the owner reviews on its store.
It suits a developer or an early adopter who wants the most capable display glasses on sale and will carry a charger. For anyone who expects glasses to last a day out, the unrated battery is the risk to weigh.
