Bengaluru, India — GRAVL, a Bengaluru-based consumer electronics brand, is changing how Indians think about portable power with its lineup of semi-solid battery power banks. Built on next-generation battery chemistry, GRAVL power banks are designed to charge faster, last longer, and run safer than the lithium-ion power banks most people are used to.

A Safer Kind of Power Bank
Traditional lithium-ion power banks carry a well-known risk: under heat, physical damage, or prolonged use, their liquid electrolyte can become unstable, occasionally leading to swelling, overheating, or in rare cases, fire. GRAVL's semi-solid battery technology replaces that liquid electrolyte with a gel-like semi-solid alternative, significantly reducing the risk of thermal runaway while improving overall battery stability.

"We didn't want to build just another power bank," a GRAVL spokesperson said. "We wanted to build one that people could trust in their bags, their cars, and their homes without worrying about what's happening inside the cell."
That trust is central to the brand's identity. Every GRAVL power bank is backed by a 4-year warranty, reflecting the company's confidence in its semi-solid cell design and long-term durability testing. Which stands for peace of mind, safety, reliability, and transparency.

Built for How India Actually Uses Power Banks
GRAVL's product lineup, including models like the Sigma 35 and Qi Surface, is built around real-world Indian use cases: long commutes, frequent power cuts, travel, and outdoor trips where wall charging isn't always an option. The Qi Surface brings wireless charging into the mix, letting users skip the cable entirely, while higher-capacity models in the lineup are aimed at users who need multiple full charges before they see an outlet again.

Beyond specs, GRAVL has also been building out dedicated content for specific use cases, including trekking and outdoor travel, recognizing that power bank needs change dramatically depending on where and how someone is using one.
Why Semi-Solid Batteries Matter
Semi-solid battery technology sits at the midpoint between conventional lithium-ion and fully solid-state batteries, the technology many expect to eventually replace lithium-ion in consumer electronics and EVs. By adopting semi-solid cells now, GRAVL is positioning itself ahead of a broader industry shift, while giving everyday consumers access to safer battery technology today rather than years from now.

Key advantages of GRAVL's semi-solid battery power banks include:
Improved thermal stability, reducing the risk of overheating during charging
Longer cycle life, meaning the battery retains capacity over more charge cycles
Higher energy density, allowing more power in a compact form factor
Reduced fire risk compared to conventional liquid-electrolyte lithium-ion cells
