Belkin's First Semi-Solid-State Power Banks Push the Chemistry Mainstream

Belkin launched its first semi-solid-state power banks under the BoostSolid Cell brand, joining BMX, Kuxiu, and Zens in adopting the chemistry. The UltraCharge Pro line starts at $69.99 for 5,000mAh and $89.99 for 10,000mAh. Belkin, which has sold over 1 billion products, claims the gel-electrolyte cells last up to 3x longer and reduce overheating risk; independent data is not yet available.
