Belkin launches longer-lasting semi-solid-state power banks

Belkin has launched its first power banks using semi-solid-state battery technology, joining a growing list of brands adopting the next-gen design. The company says its new models last up to three times longer than conventional lithium-ion power banks, thanks to a gel-like layer added to the traditional liquid electrolyte.

The move reflects a broader industry push toward safer, longer-lasting portable batteries. Semi-solid-state batteries bridge the gap between today’s liquid-based lithium-ion cells and future all-solid-state designs, which promise even greater energy density and stability. Brands like BMX, Kuxiu, and Zens have already released similar products, signaling a shift as manufacturers seek to meet demand for more reliable and durable power solutions.

Belkin’s power banks use a hybrid approach, combining a gel-like electrolyte with liquid components to improve longevity and reduce degradation over time. While the company hasn’t disclosed full technical specifications, it positions the new line as a premium option for consumers frustrated by the short lifespan of traditional power banks.

The announcement comes as solid-state battery technology inches closer to mainstream adoption, with startups and automakers investing heavily in the space. For now, semi-solid-state offerings like Belkin’s provide a practical middle ground, delivering measurable improvements without the high costs and production challenges of full solid-state designs. Expect more brands to follow suit as the tech matures.
