- AC Power Supply Adapter for AAA Battery,Replace 3 AAA Battery,Black

This worked perfectly in our halloween skeletons. They all took batteries! This made life so much easier, especially when we had them plugged into our timer. No more going outside to turn on their eyes lol

Works well at replacing batteries. Pays for itself in short time for high battery consuming items. I have used 6 of these in lighted decorative items and it is an easy transformation to keep lights and devices on. No more constant battery changes and lights going dark. These are rated at 4.5 volts to replace 3 batteries. I tried a regular USB cord but 5-6 volts is too much for some LED drivers. This solves the problem. These are good in seasonal items as it works just a battery replacement and can used on multiple items>

This adapter is easy to use, it's compatible with anything that needs AAA batteries, this is a durable, space saving product that is versatile and functions great, definitely a game changer so you're not buying batteries all the time

We used this for a museum Christmas display of trains. Most of the trains were O gauge and one of the sets used a remote control. We had a timer set up to run the trains when visitors walked in. Unfortunately the remote had to be on the entire time for that particular train even when it wasn’t running. Lots of wasted batteries. This device lets us run the engine practically indefinitely. Since it uses dummy batteries and is plugged in to a regular outlet it solved our problem of replacing batteries all the time. These are simple to use and the cord is long enough to reach the outlet we needed. Will definitely buy more of these as we expand the train layout.

Good quality, lightweight, and gets the job done perfectly. I ordered it for a small entrance project so I could leave my device on all night without worrying about constantly replacing 3 AAA batteries. Works exactly as expected and has been very convenient. Highly recommended.

I bought a string light set set for my patio. It takes 3 AAA. The "dummy" batteries were loose, meaning no electrical contact. To fix this, I carefully stretched the coil spring (that makes contact with the negative side of the battery) with my fingernail, being sure not to damage the battery module for the lights. This was just enough to barely snug-up the batteries and the device works fine. Overall, the picture makes the bulbs appear bigger. Just know, they are pretty small, maybe 1-inch. Also, they are not super bright, meaning they don't provide functional lighting, but more an aesthetic appeal. The price is good.

Love these for counter decor that I want to stay lit. Keeps from having to replace batteries all the time. Durable and easy to use. Great value.

I love these! I have the AAA and the AA ones. They are perfect for those Christmas neon signs or literally anything that has batteries that you get tired of dying. I was over spending so much money on batteries. I work in an office for 10+ hours and at Christmas I have some of those neon decor signs. These are perfect! Last all day without an inkling of depletion. Recommend fully.

Funciona perfecto y el cable es muy delgado para que permita cerrar la tapa de las baterías del artículo que vas a utilizar

Parfait pour alimenter mes "bougies" à LED. Fini les piles!

This AAA battery replacement power supply works perfectly in my three, previously battery-operated, candles. The flat ribbon which is connected to one of the artificial batteries is thin enough that the lead for the enclosure on the battery compartment can be put back in place. Considering I like the candles on all the time this simple power supply has already paid for itself in the number of batteries I have saved. Note I have three candles all battery-operated which each take three batteries. So I bought three of these power supply units.

Ordered this for one of my Christmas houses that is only battery operated, by mistake I ordered AAA instead of AA. Contacted seller and they were quick to respond and said I could return. Decided to keep it as it works with another of my Christmas decorations. Wonderful product will save $$ in batteries. Interaction with seller was great.

My first and foremost concern is safety. This dummy battery is thoughtfully designed and safe. Even the ribbon design so that battery compartment can close and use AC power. I was hesitant to purchase but glad that I did and will purchase more for my other battery powered decor that I leave on/am sick of replacing batteries for.
