DGZZI USB Female Socket 4 AA Battery Case Box Holder with ON-Off Switch

It does work but it drains the batteries within a few hours. Not really worth it if you have to constantly be changing the batteries, which are expensive.

This was great, a real lifesaver. I'd purchased fancy 'fairy' lights for the little Christmas tree for my grandson. I was so excited when they and their remote controller arrived but I couldn't plug it in to anything but a USB port. Where's an almost three year old going to plug that in?? I went back to Amazon to find a power device which hooked up to a USB. Voila! Perfect, insert several batteries, plug the lights and there's a tree any three year old would love. I showed him how to turn it off and on on the battery pack and all the grown-ups were comfortable with him being in charge. Thanks...

Totally fixed my problem….thanks very much😉

released smoke after second battery test, unlikely to have survived the fall after i threw it outside of the house for safetyit was going to get 3 stars before that from my other test, it goes from 8w, to 6w, to4w pretty quickly (under 30min) then sticks around 4 w a bit before dieing out when batteries go just under 1.2 v, when i tested it the first time, the batteries got rather warm, so i did not think that aa batteries are up for the task of powering a phone, although with todays smoke failure it possibly could be a short or defective product, if everyone elses version is working well, and can give 6w at a normal time, then it may be better and i just got a bad one, but mine could not live up to its info

I bought this to hook up to my strip of RGB lights that I put under my computer desk. There were only 2 outlets that I could have hooked them up to, but they were being used by my computer and lamp, and I didn't want to have to connect and disconnect every time I wanted to turn the lights on. With this, I can easily turn it off and on, and I plan on gluing the battery under my desk so that there's no visible cables, and it all looks like magic. The build of the case was ok, a bit cheap looking, but it does its job very well. I tried connecting it with my iPhone to see if it would charge, but my phone did not recognize any charge coming in. After a while of it being on, I noticed it feel a bit warm, but not much that it's concerning. I would probably buy it again for any future usb lights.

If you are tired of rechargable batteries that dont deliver what they promise. You love this product. I use this and regular alkaline to run mini security cameras. There are few rechargable battery on the market without autoshutoff. Well alkaline doesnt need autoshut off and lasts a lot more than rechargable. Until rechargables are fixed I am using this product and Alkaline to run crutial equipment that still need continous power and 1.5v

Not as delicate as other products but still not as solid as needed for go kit use. I had to buy a different product in case this one fails.

I've never found that portable devices that can be charged to charge something else are adequate. 4 good ol' aa batteries do the trick with this. As long as you have batteries, you can charge anything with a usb plug. I'm quite happy to have found this.

It worked for about 3 days and then stopped.
