I gave my older model Rachio lawn sprinkler to my son. This best fits a straight barrel power plug, but I had lost this from the old unit. There are negative reviiews of this item, but who writes a positive review for standard items such as a hammer? I plugged this in without load for 48 hours. It became warm as expected. This class 2 transformer is rated to tolerate a complete short indefinitely without failing or causing a fire. This is because of a designed high leakage inductance which limits current input under any condition. This is the reason for the warmth. All the home thermostats are connected to furnaces and air conditioners with 24 VAC from a class 2 transformer. They are considered safe and used in hundreds of million homes.

The picture is of a much smaller transformer or power supply. The metric dimensions are correct.

This 24VAC/1A wallwart overheated and burned out on first use with a circuit that doesn't come close to drawing 0.5A. Other Jameco units, e.g. 24VAC/2A work fine. Must be a short internal to these 1A units.Update: got a 2nd unit and it showed the same behavior so I changed the input (female) connector to one that was isolated from the general chassis grounding and the transformer no longer showed any shorting behavior. So this 1A unit does work but the correct input connection is important

Power brick died and I tried a bunch of different bricks. Turns out you need a 24VAC to 24VAC which is less common than 24VDC. Using a 24VDC caused my valves to not fully close after the timer was finished, causing leaks until I unplugged the power. This transformer works correctly with my Rachio 3

The Model No. 242901-00 adapter for my Black and Decker CMM1000, 24V rechargeable lawnmower died. The original adapter was rated In: 120V, Out: 26VAC, 1A (1000mA).I cut off the plug for this Jameco adapter and spliced in the end from my old adapter and it appears to work with no issues - the mower's green charged LED came on. I'll see how it does when I next use the mower and it needs a full charge.I was concerned that the Jameco adapter's rated output of 24VAC was less than the original adapter but I measured the output voltage of the Jameco with no load and it was around 27VAC. It probably drops under load to the rated voltage. I will update this review once I have tried to charge after using the mower.

I bought this when my Rachio 3 Sprinkler Controller died and it was only the power supply. It fit perfectly iIn the Rachio outdoor housing and works like the original.
