These are a must have in your battery stash

Great item, great price! Fast delivery. Love it

This is a good set of AAA -> AA battery adapters. Very simple and straightforward. I did have 1 of 10 that had a bad molding, but I think that is okay at the price point (I only needed two anyway). If you were buying a great quantity of adapters, you might want to consider a more premium product that had more reliable or durable manufacture.

The media could not be loaded. These adapters are well made. If you don't care to get 20 of these adapters, $5.99 for 10 is the best value on Amazon today on 2023/11/13.It's a simple device with a two part plastic piece with metal leads that are pushed through the holes on the ends. Some of the metal leads were loose, but it shouldn't be a problem after putting the AAA battery inside, unless if the piece falls out completely, then that would be annoying.I used these to hardwire a Blink doorbell camera. Wires were soldered to the inner end of the leads, and the upper and lower portions of the battery adapter was filled with hot glue.Originally, this older house had a 12 VAC 6 mA all-in-one doorbell-transformer with a two conductor wire that ran from it to the doorbell. 12 VAC is inadequate to power part of the function of the Blink camera, and is even inappropriate to power the doorbell using the Blink doorbell button. Having given up getting the original doorbell to ring, I had set up a Blink Mini in the living room that rang when the Blink doorbell button was pressed. With the high amount of human traffic going by the front door and 12 VAC being inadequate to power anything the Blink needed, I hardwired the Blink doorbell camera.In place of the original all-in-one doorbell-transformer unit, I installed a 16 VAC/30 VA doorbell transformer (Defiant brand from Home Depot) and an AC to DC step down buck converter (ASIN: B0BJKN2GGG). Then, the two conductor wire connected the AC to DC step down buck converter to the Blink doorbell camera using the AA adapter that I made. The camera was powered with 3 VDC.

Converts AAA to AA. Pretty cool, yeah?

Great

Handy little gadgets. Ran out of AA batteries, and they were a lifesaver. Nice to have when the need arises.

These are perfect for when you only have AAA batteries and need AA batteries, works perfectly, now I only have to buy AAA size only, never have to worry I don't have correct size anymore on hand.
