# Charging Power Banks Lumacore's Perovskite Power Bank Recharges Without Direct Sun By Adam Harrie | Written with AI assistance | Published 2026-10-05 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/charging-power-banks References: [gadgetify](https://www.gadgetify.com/lumacore-perovskite)  Lumacore is making backup charging less sun-dependent with its 'Self-Charging Power Bank,' a portable battery that can recharge under everyday indoor light. The device uses perovskite, a light-harvesting material, so it can keep taking in energy without the direct-sun setup that usually comes with solar-style chargers. Its [15W magnetic wireless charging](https://www.trendhunter.com/trends/ugreen-magflow-magnetic-power-bank) and [MagSafe compatibility](https://www.trendhunter.com/trends/iniu-snapgo-air) also shift it from emergency gear to something people can use throughout the day. Users can snap a phone on for cable-free top-offs, making the pack feel more like part of a daily routine than a backup brick waiting for a blackout. For consumers, this means a [portable charger](https://www.trendhunter.com/trends/portable-batterycharging-device) that requires less planning and fewer ideal conditions before it starts helping. It also nudges the category toward a more hybrid, pocket-ready role, where convenience between charges matters alongside the usual promise of extra battery life.
