Description

Chargerless Ray is a 7 g solar-powered wellness tracker designed for continuous wear. It tracks sleep, heart rate, heart-rate variability, temperature and steps without a charging port or subscription.

About one minute of direct outdoor sunlight per day keeps Ray powered, with roughly 60 days of reserve in darkness. Its lightweight, jewelry-like design makes wellness tracking part of everyday wear without routine charging breaks.

Ray starts at $219. Batch 3 is available for preorder, with shipping expected December 2026–January 2027.

Chargerless is based in San Francisco and was founded in 2025 by Andy Kong, who studied at MIT and previously worked at Google. Visit getchargerless.com for product details and preorders.
