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

Game-Changer for Battery-Powered Devices!This battery replacement system is a brilliant solution for cutting down on disposable batteries! It works flawlessly—I tested it on my small waterproof LED light, and despite the ultra-thin cable, the battery compartment almost fully closed (99.9%!). While I won’t be submerging it in water, I love that it powers my device seamlessly.I only wish I had a Game Boy to relive some classic gaming sessions because this setup would let me play for hours without worrying about dead batteries. The dummy batteries fit perfectly, and my item powered on instantly. It’s a fantastic way to save money and reduce waste, especially since traditional batteries aren’t as common as they used to be.All in all, I’m thrilled with this purchase! Amazon, keep the eco-friendly innovations coming—I’d love to try more sustainable solutions like this! 🌿♻️

Can’t count the number of these we’ve bought over the years as they are AWESOME! Replaces the need to never change batteries again and when plugged into a smart switch or smart outlet, you can have them come on and turn off at a set time/day. We use these where ever we have access to an outlet and something takes batteries.

Got this for my Sideshow/HotToys stormtrooper base--the one with the LED Deathstar-wall stand. I wasn't going to run batteries constantly in the thing (what a joke). This works absolutely perfectly. I left it on for several hours to test the heat and output, and it is exactly what I needed. Didn't get hot at all, and it provides the perfect amount of output to keep the lights glowing at their best. The thin cable worked out absolutely perfectly, and I was able to tape it to the back of the stand without any weird bulging or destructive spots. So glad I found this.

These are awesome instead of using batteries that get eaten by decorations. It's so easy to use you just put the dummy batteries that are included into the battery compartments of the item and then connect the plug to an electric outlet or extension cord. Awesome, you are saving big bucks on batteries and you get to use the device requiring the batteries at a much lower cost.

Works perfectly! I was always frustrated having to replace batteries all the time, now I have this plugged in and into a smart switch and I have this scheduled on and off whenever I want! Perfect!

Bought this for a decoration that I was constantly swapping batteries and having to flip a switch on and off when I wanted it to work. Now with this I can very easily plug this in with my Christmas tree on the same smart plug and everything can turn on a d off at the same time! I was going to just buy a power supply and solder wires onto the battery terminals but with this I can easily convert back to batteries if I wanted.The only reason I am knocked a star off is because the power lead off the main "battery" is a fairly solid ribbon cable (which is actually convenient for routing through battery cover plates) and everything was shoved into a small bag inside the products box with the ribbon cable all twisted and bent... Just makes me wonder how long this will last because of how tight the bends on the ribbon cable were and if it will break after some use because I had to straighten it out... Definitely should have been rolled up rather than wadded into a bag...

Great product. No longer burn through batteries during the holidays and am able to automate turning the decor on/off by plugging these into a smart switch. I do wish this company would expand into other popular battery sizes. I have several decorations that require 3x LR44 batteries and single CR2032 batteries.

Perfect for my needs and easy to install…NO MORE BATTERIES FOR THE WIFE’s DECORATIONS!
