1 s to 999 h Short/Long On-Off Interval Repeat Cycle Timer Plug Outlet with Countdown and Light Sensor, Waterproof for Outdoor (15A ¾HP)

These are great. We use them to power cycle our 48v chargers every couple of days. Also use them for brewing kombucha. Well made and so far so good.

Nice timer that is super easy to program - I used it to cycle on/off a DIY pool heater I made.

Simple to set up works great with my EZ clone machine 1 minute on 4 minutes off

The best timer/photo cell on the market, so many options and always works.Highly recommended

I really like this product. In most cases after power failure it starts right up and begins its timing cycle. However, I was using it to turn a pump on and off and when power is lost during pumping it could reset into programming mode. As long as the pump was off when power was lost, it seems to be ok. Also, the module turning the pump on and off was ok as well. It occasionally resets only when power is lost and the pump is pumping.Perhaps a surge protector on the motor would help this but hasn’t been tested.

This product came with instructions, but the layout and simplicity of this device is so intuitive you won't need them. If all electronics manufacturers could take a lesson from this company and make their devices this simple to use right out of the box, then nobody would be intimidated by new technology.I bought this item to power up a kerosene heater in my barn for these frigid winter days of 30° and below (as cold as 4° so far this season). Basically you can't let a kerosene heater run non-stop in enclosed areas because of the exhaust. This timer allows me to set the heater to power up for 5 minutes, then remain off for 25 minutes and repeat. No more walking out to the barn to plug the heater in and waiting for it to run its course before powering down to go back to the house. A fantastic item for anything that needs on/off/repeat cycles.

Just what I needed to control the water pump on my hydroponic garden. Easy to setup and change the programming. Keeps working when it gets wet.
