It works great and does help save $$ from Energy Vampires (appliances that still draw energy even when off). It has a small footprint and cheap to boot. I have combined this with other Products like their energy monitor and their surges with remotes and have noticed definite savings in our electric bill. It’s cheap enough to buy a few of them for other electronics in the house.
Overcharging just destroyed those batteries (and it’s not too good on the lithium batteries, either). So I’d set a mechanical timer to a few hours, and walk away. That way we could charge a bank of batteries with a control on each charger.
When I moved to 18v lithium tools, i got these electronic timers. I have found them ideal for this purpose. I use mostly Milwaukee red lithium 18v systems, so the built-in battery charge indicator is a pretty good indicator of the amount of charging required: i’ve found that the smaller red lithium batteries require about 30 min for a half charge, the bigger red lithium battery packs require 1-2 hours for a full change, and so forth. This outlet allows me to time the charge accordingly. 3 hours is more than enough time for Milwaukee battery packs, and yet not too much overcharge.
These chargers are also useful for charging acid battery packs which are from my experience very sensitive to overcharging. I use these outlet timers to charge the batteries on my Currie e_bikes – just set the timer, plug in the charger, and walk away. Full charge takes about 6 hours.
I have had 3 of these for several years, and use them with power strips in the garage. They seem to work fine for my applications. Recommended.
I’d give it five stars if there was a way to shut off the timer once you have initiated power to a device. As it is, the minimum setting is for 1/2 an hour of power, and, once you start the timer, there is no way to shut it off without pulling the timer out of the socket.
Other than that, this little device is a real power saver, especially on high consumption electrical appliances like heaters and fans.
Works nicely in wall outlet. Good for setting device and using this item to switch device on and off. Make sure whether you need a two-prong or three-prong type. Quality made, but would like to see if less expensive that $6+ each. I would havbe bought more if they were discounted for quantity.
