Other Power Banks Need Charging. Lumacore Charges Itself.
Lumacore
Lumacore quietly adds juice back on its own, offsets self-discharge, and stays ready without you thinking about it, with any kind of light.
Traditional solar power bank
Solar power banks promised off-the-grid power, but they didn't deliver, and usually require direct sunlight.
Everyday power bank
Everyday power banks are always with you, but not always ready.

Designed in Palo Alto
Our journey began in the Bay Area with a simple goal: rethink how everyday devices can harvest energy. Through years of R&D in next-generation perovskite technology, we developed a power solution designed to perform where traditional solar falls short — even in low-light environments.
FAQs
Most solar power banks use silicon cells that need hours of direct sunlight to do anything useful. Lumacore uses perovskite, a new solar material that converts indoor and ambient light into power, not just full sun. That means it keeps charging on your desk, in a café, or near a window.
Yes. Under normal room lighting Lumacore is always collecting power in the background, so the pack stays topped up between uses instead of sitting there draining.
Yes, you can charge your phone and collect solar at the same time.
Yes. Lumacore will be UN 38.3 certified, so it's allowed in carry-on baggage. Like all power banks, it can't go in checked luggage.
UL 62368-1, UL 2056, UL 2738, UN 38.3, FCC, and official Qi2 certification from the Wireless Power Consortium.
