Tested Watts exists for one reason: to tell you exactly what a portable power station can run, and for how long, before you spend $500 to $2,000 on one.
Spec sheets tell you the battery capacity. They don’t tell you whether your refrigerator will make it through the night, how many nights your CPAP will last during an outage, or how long solar panels really take to refill the battery. We answer those questions with transparent math, verified specifications and public data. Every number is labeled so you know where it comes from.
Who is behind Tested Watts
Tested Watts is written by Alejandro Rodríguez, MD, a physician trained and practicing in Colombia, where I work in rural primary and emergency care. I’m not licensed to practice medicine in the United States. Medicine taught me two habits that shape this site: check the numbers before you conclude, and never recommend something you wouldn’t trust with a patient. That matters most for readers who depend on powered medical devices, such as CPAP machines, during a power outage.
Colombia runs on the same 110–120 V, 60 Hz grid as the United States, so when I measure household appliances, the readings are comparable to what American readers see at home. I haven’t tested power stations hands-on yet: our reviews are based on official specifications and transparent runtime math, and each one says so.
What we promise
- Real numbers. Runtimes, charge times and usable capacity are clearly labeled calculations from official specs, with the formula shown. Anything we measure ourselves is labeled “Measured at home.”
- Honest verdicts. If a product’s specs fall short for a use case, we say so, even when it pays a commission.
- Transparency. We may earn money through affiliate links and ads. Read our Affiliate Disclosure and How We Research pages for the details.
