First off, if you want these in a hurry, buy them from another seller. I ordered these on 2/12 and they arrived on 3/13 after several shipping delays. One more day and I could have gotten my money back. They are shipped from Bakau, Gambia, wherever that is. Quality is fairly good, they work OK. Not all the halves were completely closed, so before you jam one of these into a cylindrical AA flashlight make sure it goes in easily, otherwise you may never get it out again. I might try converting one of these into a USB wired power unit, if that's successful I'll post an update. For the price they are pretty good, just not really great. Read more
I purchased these to modify a battery powered device to run on corded power. The positive and negative terminals are connected with a wire.

These do what they need to do: take up the space of a battery when you need to lower a voltage. The issue with them is the positive connection is shallow so it doesn't make contact in some battery boxes. You will need to resort to some kind of filler to bridge the gap between the dummy positive and whatever you are putting it into. Read more
Went together well, I was pleased with the result. Soldering was done with leaded solder, not tin only. I am glad there was a video on assembly of this autotransformer on YouTube. Thank you again !! Read more
These work great. I found these from a reference on a YouTube video. Not all electronics work with Rechargeable batteries so I bought these to “fool” the device. Did the job Read more
