Leo Esposito

Leo Esposito is an electrical engineer turned independent reviewer who has spent the last six years stress-testing portable power stations in real apartment conditions. Trained in power electronics at Politecnico di Milano, Leo focuses on the technical side of backup power — inverter efficiency, LiFePO4 cycle life, UPS-mode transfer times, and indoor safety. He runs the lab teardowns and bench-measures every unit we recommend before it lands in a guide. Based in a Brooklyn one-bedroom rental with regular ConEd brownouts, he understands the difference between marketing wattage claims and what actually keeps a router, laptop, and CPAP machine alive at 3 AM.
