We needed this to open a batter operated safe (of course the batteries died) and this did the trick! A must have for everyone!

Not worth the money spent..

Battery died in my gun safe :( My fault, didn't change batteries out after two years. Any how, misplaced both keys. Watched some Youtube videos on how to open safe without having to pay $100s to break in to it. Stumbled upon video using external battery pack with a 3.5mm audio jack that inserts into front door of safe as an emergency failsafe in the event battery dies. When it was delivered, I got it, opened and installed batteries in the pack, prayed, inserted the small jack into the front door of the safe, powered on the battery pack, pressed the pin code as I heard the beeps come alive with every push of the buttons as the green light flashed twice indicating the locking mechanism engage releasing the handle to freely turn and open the safe door. I was SOOOOO HAPPY!!!! :) :) :) As this applies to my battery operated biometric lock mechanism, this is my emergency failsafe emergency key!

Who doesn't have a few rechargeable items without the charger cords or has 6 different charge boxes still hanging around cluttering up their drawer? We had both. We found this and it replaced several and allowed us to clean up the electronic drawer and still know we had what we needed to charge that older item that uses these types of connections and not the newer USB and USBC type connections.

It did what I needed to do unlocked my small safe
