ReelCharge's $50 semi-solid-state power bank promises safer flights

Lithium-ion power banks are a known fire hazard on airplanes, with viral videos showing devices bursting into flames in overhead bins. ReelCharge aims to solve this with its new 5,000mAh power bank featuring semi-solid-state battery technology. This chemistry is inherently safer because the electrolyte is not as flammable as the liquid used in standard lithium-ion cells, significantly reducing the risk of thermal runaway. The device costs $49.99 at Best Buy and B&H Photo-Video, with a larger 10,000mAh version also available. ZDNET's reviewer gives it 4.5/5 stars, praising its sleek design and safety credentials, though the button feels a bit rattly.

The semi-solid-state design addresses the core problem: lithium-ion batteries store energy that can be released as heat extremely quickly, turning a small cell into a fire source in seconds. While the energy capacity is similar to a 5,000mAh standard power bank, the key difference is in how the battery handles stress, impact, or manufacturing defects. ReelCharge is positioning this as a travel-ready companion for frequent fliers, especially as airlines tighten restrictions on damaged or counterfeit batteries. For consumers, the practical benefit is peace of mind: you can charge your phone without worrying about starting a fire in your bag, car, or bedroom. The tradeoff includes a slightly bulkier build and a less premium button, but the safety advantage outweighs those minor flaws for many users.
