Lenink Power Supply Cable for AA Battery, Replace AA Battery

I’ve spent years going through batteries for fairy lights for the holidays. I spent a lot of money on lithium rechargeable batteries which need up being a bust as they die quickly. These solved my problem! I can put them in any decorations I have that take batteries. Great value. Easy to install. The cord is super long. Note they should ONLY be used indoors, and probably monitor the first couple days to make sure it doesn’t result in any electrical issues. But otherwise, looking forward to using these in all my decor!

Used this with a portable bubble machine and it worked great! We were able to use the machine for a few hours until we ran out of the gallon of bubble solution. Made it super easy to leave plugged in and not need a ton of batteries during a party.

I’ve been using this to power a display piece I have for a year now nonstop. There has been no issues and the product works like a dream. An absolute must for battery powered display pieces or model kits.

I got this really cute lighted display that required 4-AA batteries. Man, I hate it when I love a lighted piece that is powered by batteries because if I leave it on all day because I like it, I'll be going though batteries like crazy, and even if they are rechargeable batteries, I have to constantly recharge them. What a pain! So I found this fake battery thing-y - where it replaces the batteries with fake ones that create the circuit needed, but the power comes from the usb cable. I can plug my little lighted display and have it lit up all day and not worry about changing batteries. Great idea that works well!

This is a really neat idea that I wish I'd come across sooner. I have two of these in decorative AA powered lights, one with 3 batteries and the other with 4. The very thin Lenink tape wire clears the battery compartment in both devices so that the compartment covers still snap shut. So far they work well; we'll see if they last. What's not great about the Lenink set is the necessary USB to AC adapter is not included, so as sold the set is incomplete.

I use them for all my Christmas decorations that require batteries. Not only they help saving the planet but now I can enjoy and keep all my Christmas decoration lit up for hours without worrying to replace or recharge batteries.

If you're tired of replacing batteries in a candle, this will make your life much easier and profitable.

This is way too expensive for what it is. The battery wire is also way too thin, if you pinch it you can damage it very easily. Poor quality. It also burns out LED bulbs over time, I guess the power it outputs is out of spec from regular batteries.

Hard wired an eve aqua with these and it now works a treat and I never have to replace these batteries again.

Fire hazard, dark smoke coming out after only being on on 2-3 occasions

Bought this item to power battery operated Christmas working displays and they proved to be ideal for this purpose instead of using countless batteries. Very easy to set up and they performed brilliantly over the festive period.

So... I got this I'm hopes of using it on my clock and never need to get new batteries . It's an outdoor clock. But it won't work... Clock takes just one battery AA . Too much juice for the clock. The instructions warn to use this on stuff that takes 3-4 batteries not just one. Anyway I tried with a battery operated LED light and it does work. You supply your own power charger though. So yeah it works ok. But just not for my needs.
