The editors behind Backup for Renters
A two-person editorial team that buys, benches, and lives with every portable power station before it ends up in a guide. No drop-shipped opinions, no review-mill copy.
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.
Magnus Svensen
Magnus Svensen has worked remotely from rental apartments across Stockholm, Berlin, and Portland for the last nine years — long enough to have lost work-in-progress to four blackouts, two utility maintenance windows, and one freak ice storm. He now writes about the real-world side of backup power: how loud a unit actually is at night, whether it fits under a desk, whether your landlord will object, and how much runtime you really get on a typical home office stack. Magnus does the long-form runtime tests, livability checks, and apartment-fit measurements that turn spec sheets into recommendations.
The Backup for Renters method
1. Buy retail
We purchase every unit at retail. No PR loaners, no influencer freebies. If a brand sends an unsolicited sample, it goes back unopened.
2. Bench test
Leo measures real AC output under load with a Kill-A-Watt and oscilloscope, logs runtime curves, and times UPS-mode transfer to confirm what the spec sheet claims.
3. Live test
Magnus runs each unit in a real apartment for at least two weeks: bedroom noise at night, fit under a desk, charge cycle behavior, and what actually keeps Wi-Fi online during a blackout.
4. Compare
Side-by-side against the current top picks. If a new unit doesn’t beat what we already recommend on a specific use case, it doesn’t make the guide.
