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

The product arrived ahead of schedule. It is well made. The chord for the powered battery is wafer thin and will allow the battery door to close with no problem. You do need to be careful when handling the powered battery so as not to put too much stress on the power chord for the powered battery. There is a 9-volt ac ripple (measured with a Digital voltmeter) on the power supply that did not affect the electronics in my Halloween decoration. I measured several other power supplies, and they all had an ac ripple. My decoration depleted 3 batteries in 5 days on the 6 hour internal timer. This product works great and will save me 15 AAA batteries. I have already purchased a 3 double AAA battery and a 3 Tripple AA battery units

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.

This is SUCH a great item. I have holiday decorations requiring batteries, a few of which eat said batteries pretty quickly. This item, which is very easy to use, keeps batteries out of landfills and makes life more convenient. I expect I'll pay a little more in my electric bill next month, but in the long run this will be a money saver compared to the batteries I'd ordinarily buy. Highly recommend.

This worked great, powers my battery unit perfectly and it won't be sucking $$$ batteries ever again!

Amazing invention for Halloween Decoration that use batteries

Nice don't have to worry about batteries running out

Oh my gosh! These are so simple to switch your battery powered items to wall plugs

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

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.

These are absolutely amazing for turning anything battery operated into electric. I personally use them primarily for my Halloween animatronics that are all battery operated for my haunted house and turn them into electric like more expensive. Kind saving me from having to change batteries all Halloween season. I've also used a set of them with my force effects. Lightsaber to create a light that is always on with my lightsaber.
