Solar Power Bank Charges in 26 Minutes, Tops Off in Sunlight

Running out of battery power while traveling might soon become a problem of the past, thanks to a power bank that charges itself using sunlight.

The Solly power bank wraps a solar panel around its exterior, letting users recharge simply by leaving it in the sun. While solar charging takes over a day to fully power the device, it provides a reliable backup option for outdoor adventures or emergencies.

What makes this gadget stand out is how it solves multiple travel problems at once. The device serves as both a high-capacity power bank and a travel adapter, with foldable US, UK, or EU wall plug prongs built right in. Travelers can ditch their separate adapters and enjoy pass-through charging that powers devices directly without draining the internal battery.

The 20,000-mAh capacity provides enough juice to recharge an iPhone 17 Pro Max four times. Two USB-C ports deliver 140 watts of output each, making the Solly powerful enough to quickly charge laptops and other demanding devices.

Safety gets a major upgrade too. The Solly uses solid-state battery technology, which replaces flammable liquid electrolytes with solid materials. These batteries won't burst into flames if damaged or punctured, making them much safer for everyday use.

When plugged into a wall outlet, the power bank fully charges in just 26 minutes. The shock-proof, water-resistant exterior protects the device from travel wear and tear. At 14 ounces and roughly the size of a deck of cards, it slips easily into pockets or bags.

The Bright Side

This innovation points toward a future where our devices work harder for us. By combining solar charging, fast wall charging, and travel adapter functions, the Solly eliminates the need to carry multiple gadgets. The solid-state battery technology also represents a meaningful step forward in device safety and longevity.

The company claims the battery will retain over 80% of its performance after 3,500 charging cycles, roughly three years of regular use. That durability means less electronic waste and fewer replacements over time.

The Solly launched on Kickstarter at $79, discounted from its expected $115 retail price. Orders are scheduled to ship worldwide in August 2026. While crowdfunding campaigns carry inherent risks and this appears to be a new brand's first product, the technology offers a glimpse of smarter, more sustainable travel gear.

One device that charges in sunlight, powers your laptop, and works in any country shows how innovation can make life simpler.
