Avoalre 40M300LED Battery-Powered String Lights, 300 Warm White LEDs

Avoalre 40M300LED string lights offer 300 warm white LEDs on a 40-metre battery-powered string, with eight lighting modes and a timer. They suit decorations away from a mains socket, but the battery box needs protection from rain.

At a glance

Battery operation allows placement where a mains socket is inconvenient.
Eight selectable modes include steady-on and several changing effects, with a claimed memory function for the last selected mode.
The timer is described as running for six hours before switching off for 18 hours.
The listing says the battery box is not waterproof, despite the lights being described as IP44 rated.

Pros and cons

Pros

A 40-metre run with 300 LEDs offers substantial length for decorating trees, rooms and other spaces.
The supplied feature claims include eight modes, a timer and memory of the last selected mode.
Battery operation avoids dependence on a nearby power outlet.

Cons

Three AA batteries are required and are not included, so they must be supplied separately.

What to know before buying

Listing details to confirm

The IP44 claim applies to the LED string, not the battery box. Keep the battery box protected from water. The listing also gives a 40-metre string plus a detachable 0.4-metre battery box, while the title says “40+0.4m”, so confirm what length is being counted if exact total reach matters.

The supplied evidence contains aggregate ratings but no written customer-feedback summary, so it does not identify specific reported strengths, complaints or reasons for ratings. The overall rating distribution is mixed, with a majority of five-star ratings but a substantial one-star share. That spread suggests buyer experiences are not uniform, but it cannot establish how the lights perform or what caused dissatisfaction.

Frequently asked questions

Are batteries included?

No. The listing specifies three AA batteries and says they are not included.

Can these lights be used outdoors?

The listing describes indoor and outdoor use and gives the light string an IP44 rating. It specifically says the battery box is not waterproof, so keep that protected from water.

What does the timer do?

The stated timer keeps the lights on for six hours, then off for 18 hours in a 24-hour cycle.

How long is the light string?

The listed item length is 40 metres. The feature text separately mentions a detachable 0.4-metre battery box, so the title's “40+0.4m” should not be assumed to mean 40.4 metres of illuminated string.
