DIANN 20pcs AAA to AA Converter AAA to AA Battery Adapter AAA to AA Battery Converter Holder AAA to AA Adapter

Works great!

I didn’t even know this was a thing that existed until I saw a video for it on YouTube! They actually work amazingly well! This way,, I can buy a large package of AAA batteries and use them for everything. It’s a wonderful creation.

I get a lot of discarded, still functional batteries, so I bought these to help me use some. Unfortunately some of them aren't a good fit and won't close around the battery, or will close, but make the length too long to fit in the device. They feel durable, but I can't say for certain on their strength. Could use some adjustments to be better

Wonderful item saves money

They work fine. China is known for mega production of any given product, they sell to multi distributors who slap their name on it. So when you compare any of these adaptors, they are made by the same machinery as the other brands that look exactly alike.These have a little slack to accommodate slightly different types of AAA battery, like alkaline vs rechargeable.But they have a cathode end that tightens to the battery when installed to the AA device with a tension spring - they all have springs.In other words, they work fine.

For some reason, I seem to run out of AA batteries and I always have AAA batterieswith this product. I can get by until I get more AA batteries. I think it’s great only a temporary solution but just in case.

Really wanted to like this product but when I put the battery inside the electrodes did not touch so it did not work very disappointed maybe Jen 2 will be better

very easy to use
