How we research

1. Primary sources

Every spec comes from the manufacturer's product page, manual or support docs, and we link them at the end of each article.

2. We do the math

We convert specs into answers: runtime estimates, Wh needed and real differences between models, with our assumptions shown.

3. Honest limits

We don't run hands-on lab tests, and we say so. Where ratings aren't directly comparable, we explain why instead of picking a fake winner.

We earn commissions from some links. That never changes the specs or the math. Read our disclosure.
