Former battery storage engineer turned independent reviewer. Tests power stations in real apartment-and-blackout scenarios, not lab benches.

Background

Jane spent eight years as an electrical engineer at a residential battery storage startup in Bellevue before going independent in 2023. Her focus on whatpowerfor is real-world load testing — how units actually behave under sustained heavy use, what happens to capacity after two years of weekly cycling, and whether the spec sheet matches what shows up on the meter. She owns and rotates through 6 power stations across an apartment, a cabin, and her parents' fridge-during-storms backup setup.

Areas of focus

• Battery chemistry and cycle-life testing
• Real-world load testing under sustained draw
• Solar input behavior and MPPT efficiency
• Charge controller derating in heat and cold

What Jane covers here

Product reviews, charging math and methodology, solar pairing
