Pinpoint® 9-Volt Battery Universal AC Adapter Kit 120VAC_AB

Not a lot to say. Decent price and works. I used it with a water/flood detector so I don't have to worry about batteries.

Perfect for any 9V item that stays in one place - might require you to leave the battery door off if you don't wish to modify your item to allow the cord to exit.

I bought this adapter because my TENS unit was eating expensive 9 volt batteries. As with many 9 volt devices, the battery connection inside the unit has metal strips instead of snap receptacles for the battery. One of the other reviews I read here mentioned using Legos to push the adapter snap connector up against the metal strips. The Legos are a perfect fit. To finish the job, I cut a notch in the battery cover for the adapter cord.

This thing keeps my gun safe lock powered. With a battery, I can open the safe 5-6 times before I need to replace the battery. Those days are over!

Great for 9v devices that you want to be able to power with AC adapter.Only thing is if your device doesn't have snap receiver on other end as some just have tensioned metal contacts, it doesnt fit. I was however able to make an adapter with Legos... you heard right... if you have 4 of the 2x3 blocks stacked you can carefully tape this on the top and it will fit as a 9v battery will fit into tensioned 9v recepticles. Not sure why they wouldn't go ahead and built these onto a plastic 9v sized shell since they are typically going to be used in devices that would fit the whole battery.

When I finally figured out what to ask for it was easy to find. This works with anything that needs a common 9v battery. Everything I've tried works. No more batteries for stationary objects found near an electricaloutlet.

This does what it promises -- plug it into the wall, snap the cable onto your device's 9V battery lead and voila, no more 9V batteries needed. If you want to tidy it up you could cut a small notch in the battery cover of your device so that the thin cord can run neatly out of the device to the wall wart.

I purchased this for a TENS device that was eating batteries. The device did not have the traditional 9 volt contacts but slide in contacts. I was able to use this power supply with a small clamp holding it against the side of TENS unit. For my application a more perfect design for a device like mine would be a battery sized object that slides into the device making contact at the designated points.
