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

Belkin has launched its first power banks using semi-solid-state “BoostSolid Cell” technology, which adds a gel-like layer to the liquid electrolyte of lithium-ion cells. The company says the design delivers up to three times longer lifespan, lower overheating risk, and stable output across a broader temperature range, though the units cost more than comparable models.
