Overview
Not a mains-powered fixture, this STEM zapper runs on a rechargeable battery and draws flying insects with a soft blue light from every angle, then zaps them on contact with a grid. The compact body stands on a table or hangs from a collapsible hook.
Cordless operation is the reason to buy: it moves between indoor and outdoor spots without hunting for an outlet. The battery is described as weather-proof, and no chemical insecticides are involved. The limitation is range, since the listing gives no coverage area.
Who it's for
Fruit flies in the kitchen or house flies and mosquitoes outdoors are the named targets, and the unit moves easily between spots. Buyers who need wide coverage or a fixed plug-in installation should choose a different type.
Pros and cons
- Rechargeable, micro-USB cable included

- Size and weight unstated
Performance notes
A soft blue light shining in all directions attracts flying insects, and the grid zaps them on contact. Runtime depends on the rechargeable battery, so a recharge is part of regular use. Placement near where insects gather matters more than any other setting.
