Belkin introduces first longer-lasting semi-solid-state power banks
Belkin has launched its first power banks featuring semi-solid-state battery technology. The company claims the new accessories are engineered to last up to three times longer than other power banks.

Belkin has entered the semi-solid-state battery market with the introduction of its first power banks utilizing this technology. The new accessories, branded under Belkin's BoostSolid Cell technology, incorporate a gel-like layer alongside the typical liquid electrolyte found in lithium-ion batteries.
The company asserts that this engineering allows the power banks to last up to three times longer than conventional models. Additionally, the semi-solid-state technology is reported to reduce the risk of overheating, which can cause battery swelling or potential fire hazards. Consistent power delivery across a wider temperature range is another claimed benefit.
While these advancements come at a higher price point compared to power banks with similar specifications, Belkin is positioning the new line as a more durable and safer option for consumers. The move reflects a broader industry trend towards improved battery safety and longevity in portable electronics.
