Overview
Plugging in the LectroFan EVO means choosing from non-looping sounds meant to cover room noise. The plastic housing is charcoal, the listing names a sleep timer, and an AC adapter supplies power.
A long sound list and a timer give a sleeper a choice of noise and an automatic stop. The limitation is clarity on the jack, because the listing names the connector but not its function.
Who it's for
A nursery or bedroom with outside noise is the likeliest home for it. Travelers who need battery operation, or buyers who want to know what the jack does, should confirm with the maker first.
Pros and cons
- Many non-looping sounds
- Light and compact
- Two year warranty
- Jack function not explained
- Needs wall power
- Volume range not listed
Performance notes
Non-looping sound gives the ear no repeating seam to notice, so the noise reads as steady cover. Power comes through an AC adapter, so the machine stays near an outlet.
