Portable white noise machines, value by value
Battery life is the maker's rating, not a measured runtime, and real nights vary with volume. None of the four makers publishes a decibel range. Scroll sideways on a phone to see every column.

Method and reuse
Last checked September 25, 2026.
What is included. Every machine recommended in our best portable white noise machines guide, one row per model.
Where the numbers come from. The maker's product page first, then the Amazon listing (identified by ASIN and read through the Amazon Creators API). Every value records which of the two it came from. Kit Authority did not measure battery life, weight, or volume.
Blanks. A blank means neither source publishes the figure. We do not fill gaps from owner reviews or estimates. For infant sleep, volume matters more than any spec here; our guide to whether white noise machines help you sleep covers volume safety.
Reuse. You are welcome to cite these figures, link to this page, or quote rows with credit to Kit Authority and a link back. Reuse follows our terms; to republish the full table, ask first.
Corrections. Spot a changed spec or a newer measurement? Send the source to hello@kitauthority.com. Corrections are dated here and in the CSV.
