Belkin introduces its first longer-lasting semi-solid-state power banks

Belkin is joining companies like BMX, Kuxiu, and Zens with the launch of its first power banks featuring semi-solid-state battery technology. The company claims the new accessories have been “engineered to last up to 3x longer than other power banks” with the addition of a “gel-like layer” alongside the liquid electrolyte typically found in lithium-ion batteries.

Other advantages of what Belkin is calling its BoostSolid Cell technology include a reduced risk of overheating that could cause swelling or fires and consistent power delivery across a wider temperature range. They’re more expensive than power banks with comparable specs, but a longer functional lifespan should outweigh the premium pricing.
