R-Tech 12V 1A Power Supply

I picked up this multi-pack of 12V adapters, as there is always somewhere I can use them. Turned out I needed to power some Shelly One relays in my garage for my garage openers. This was perfect, as there are already outlets on the ceiling where my openers plug in. Worked great. Note that you need to make sure your relay supports low voltage - this is true in the case of Shelly devices.

Good value, worked with my 12 volt application.

Great value. To my surprise the package included a set of diferent sized connections for different applications. Didn't really need them but is always nice when the seller is proactive about possible consumer needs.

part of the pieces I needed to convert my older garage door opener to a remote open/close from my cell phone. No glitches, No problems.

You can never have enough power packs. These are a good replacement, come with assorted adapters. Just read the polarity and power outputs.

Exactly what I needed. The cord accessories made for a nice touch. Great value

This product is listed as a "3 Pack", which one would assume means it has 3 of each of the items pictured, but it only has one set of adapters that you're supposed to use for the 3 power supplies. Who would want 3 identical wall warts but a different adapter for each one? This only makes sense for those who use the default barrel-jack size, or who are buying this for diy/soldering projects.

You get three plugs, but only one set of adapters, so if you want to use all for the same device type, you’re looking at a DIY home soldering project.
