This USB power supply cord does not come with volts. The output voltage of the product depends on the adapter being connected to. 2. Generally speaking, 2AA=3V, 3AA=4.5V, 4AA=6V, and the corresponding voltage adapter needs to be selected. 3. Due to the fact that the USB socket and most commonly used adapters are 5V1A, in view of this situation, 5V is right in that range where it should be suitable for any device that needs 3 batteries to operate. 4. For 5V USB socket, it is not recommended to use this product on 1AA and 2AA devices. 5. For 5V USB socket, some 4AA devices may fail to work due to insufficient voltage. MORE ITEMS USB to DC Power Cable AC Power Supply Adapter Review: No more changing batteries for me - I could not appreciate this product more than I do. I have a ton of holiday decorations that take batteries and I was forever changing them. I read a comment someone made online about using a converter instead of batteries and I found this product on desertcart. It’s a terrific value. No more spending a ton on batteries. You simply put the battery with the cord into your device with the dummy batteries and plug it into the wall. You’re essentially making a battery powered item cord powered. I’ve bought so many of these. They all work great. I’ve bought aa and aaa. There is even an option for three items on one plug in by the same brand. Wonderful product. Super easy to use. Very convenient. I’ve had things plugged in for months at this point with zero issues. Review: Works amazing for fairy lights and decorations - 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! ## Features - Continuous Power Supply: as long as you place in this battery replacement, you can use your device for 24 hours without changing batteries frequently, saving your time and money, and bringing more convenience to your life - Premium Material: the power supply cable is made of pure copper wire, which has better conductivity.

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! ### ⭐⭐⭐⭐⭐ This was the first, but I've bought some for AAA battery use *by C***N on June 22, 2023* 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! ## Frequently Bought Together - Lenink Power Supply Cable for AA Battery, Replace AA Battery - Lenink AC Power Supply Adapter for 3 AA Battery, AA Battery Replacement Adapter for LED Light, Decorations (Black) - Lenink AC Power Supply Adapter for AAA Battery,Replace 3 AAA Battery,Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/452973639-lenink-power-supply-cable-for-aa-battery-replace-aa-battery](https://www.desertcart.pt/products/452973639-lenink-power-supply-cable-for-aa-battery-replace-aa-battery) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-07-09*
