Grant Mercer is the founding editor of Power Backup Lab. He leads the site's research process and editorial standards across backup power, portable power stations, home battery systems, and outage preparedness. The Power Backup Lab approach does not rely on marketing claims. Every recommendation is built from three sources: official manufacturer specifications, independent lab and field testing published by trusted third parties, and verified feedback from real owners who live with these products day to day. The goal is simple and practical guidance, with no hype, so readers can choose the right backup power setup for their home and budget.
