BN-LINK 12 Hour Indoor Mechanical Accurate Countdown Timer, 3-Prong Grounded Outlet, 15 Minute Increments, Energy Saving for Kitchen, Phone Charger, Lamps, Holiday Decoration 1875W, 1/2 HP, ETL Listed

I used some creativity and mounted a 20" industrial floor standing fan minus all the parts included with it, ... into a very strong mounted whole house exit fan, simple design that's strong, no vibration, no chattering, no nothing, and adjustable for future fans when this one finally passes. This replaced a 60 year old HOBART (Sears?) whole house exit fan with a separate motor, fan belt, and fan tower all self enclosed, that I grew up with, that was fancy for the time with it's own mechanical timer. That timer worked for 60 years and did when I sold it to a collector. I've tried a few other manual timers. A mechanical timer is very basic, not much to go wrong, work perfectly, lo-tech, WORKS, mine never gets warm or seems to be exerting effort nor any odor like it's getting warm, and from experience these basic timers can last years. Turn it to where you want is, and forget it. I didn't want a bunch of buttons to push for a simple task. I like that. I bought 3 more after analyzing my first one of these under load for a month. Ran a couple tests and temps, under different loads (hi versus lo on the control) -- and this rascal passed all tests, easily. Time will tell. I will update if this fails before it should. So far this is a champ. Specifically - I am using this timer with a 1/4 hp, 20" "so-called" Industrial fan made where all of them are. The fan works well and being in a separate back room 15 feet away, almost inaudible or very tolerable, and I only need the Lo speed setting. This timer does not buzz, at all. Zip. Your fan does not make ANY buzzing sound as a result of using this timer, as some fan "speed controllers" do. These fans are meant to run warm but not hot, and mine does. *** You must provide adequate open windows or screen doors AIR FLOW to use this 20" fan exhaust setup, or the fan may get warm trying to pull MORE AIR through the home, than you are permitting - with a load to the motor. Open more windows OR buy a 16" fan and not a 20" to match it to the job you have for it. In an 1,100 sq ft first floor with open windows and screen back door, I get a WONDERFUL, tactile, air flow throughout the entire first floor. This timer is perfect for day use, and when you go to bed and want it to shut off in 3 hours. One twist down to 3, done. Buy a couple. I simply turn this timer dial clockwise down from 12, o whatever amount of time................... you want the fan to continue to operate, ... then shut off by itself - you being long asleep. Before I go to bed I turn it from it's starting point of 12, to the right or clockwise, and stop on number 3. The fan will start to rotate and 3 hours later it quietly clicks off, with a small sound, loud enough that in my sleep I heard it, but not enough to fully wake me up. Nice. All is well ............... this timer works, is ezy, has zero electrical control or heat issues with a capable 20" whole house window mounted exit fan - to pull air through your entire home's open windows on cool nights or dryer days in the spring and fall. I like that it's plug is the grounded kind, and even in an older home with a two wire wiring system, the plug itself has the ground lug, making for a better more secure contact not likely to vibrate out or by a passing dog leg. Knowing something about these devices, this one at present looks like a good tool at the right price. Highly recommended for the job it was built to do. This is not made for serious, heavy duty, industrial use but is ideal for the homeowner.

A great mechanical no bs timer for your electronics. I use it to charge my ebike, and just let it do its thing and have had no issues yet. Very simple and intuitive dial, with a decent construction. The only gripe I may have with it is the switch from a regular outlet to a timer sometimes gets switched when you don't mean to switch it, I just double check its on the timer setting and its good to go. I recommend.

Works well. I use it for a candle warmer, saves me from leaving it on too long. Easy to use.

I use this to to time my cheapo Vicks steam humidifier. It works really well for that. It operates silently. There is no audible ticking sound. The flaws are 1. It is kind of hard to distinguish the zero mark. So I need to make sure I'm wearing my reading glasses and have plenty of light. Making the zero mark easier to read in low light would be a win. 2. The always on switch is too easy to flip, and flips silently. So it's possible to accidentally turn the timer to always on and then wonder why "it stopped working". It didn't stop working. You just flipped that switch without knowing it. And because you don't use that switch, you forgot it's even there.

This timer is just what I had been looking for. A simple,reliable, countdown timer switch to control mains voltage to various devices. My primary usage is to control charging time to rechargeable devices such as: cell phones, electric shavers, or any rechargeable electronic device. Just set the ON time on the timer, plug in the device's charging adapter, and plug in the timer. No more overcharging and hopefully longer lasting batteries. I chose this timer over an electronic timer because its design is based on reliable existing ON/OFF mechanical cycle timers. If there is a momentary interruption of power the timer just turns on at its time setting before power interruption, or worst case the timer turns on in the OFF state and the timer wheel must be reset. Electronic timers sometimes do not do well with momentary power interruption and may come on in an undesired ON state that may last for hours. When the timer shuts OFF no more power is drawn. No phantom load like with an electronic timer when OFF. Almost any load can be timed up to 1/2 HP, 15 amp resistive, or tungsten lamps up to 8 amps. Timing range is 15 minutes to 12 hours in 15 minute increments. These ranges are another plus over electronic timers. The timer must reset for each use as time settings are not remembered. This is not an issue for me because each time I use is different depending on what I an powering/recharging. The device is also silent when operating, even when right next to it. The only noise is when the timer finishes and there is a slight click as the internal relay releases. I have two of these and will be getting more to use with unattended fans, heaters, and a coffee maker. Update: August 15, 2016 I now have three of these timers and they are great! The last one received will be dedicated as a travel timer to time charging of my smartphone, laptop, Kindle Reader, electric razor, and a small rechargeable flashlight..I also have a small extension cord with a three receptacle end so up to three devices with similar charge rimes and be plugged in together to the timer. I am hoping that using a timed charge will decrease stress on the batteries and extend their lives and devices lives that have non-replaceable batteries. I hate disposable electronics that is junk simply because the battery died. One of my electric razors died a early death due to overcharging the battery ($90, ouch).

Works great. Easy to use. I use it to limit the time e-bike charger runs. I haven't had it long enough to evaluate reliability.

The perfect solution for small cookers without automatic switch from the current cooking mode to stop cooking or switch to the Warm mode.

I purchased this timer specifically because it was ETL listed and advertised as being rated for 15A (1875W). My goal was to make using our 1500W portable bathroom heater safer by ensuring it would automatically shut off if we forgot to turn it off. Initially it worked well, but after some use we began noticing an intermittent problem where the heater would not turn on unless the timer was jiggled. Shortly afterward, I discovered one of the timer's plug blades had become extremely hot—hot enough that touching it nearly burned my finger. Upon inspection, I found melted plastic around the base of that blade. At that point, I immediately unplugged it because I believed it had created a potential fire hazard for my family. Our heater is rated at 1500W, which is well below this timer's advertised 1875W/15A resistive rating. Based on the intermittent operation, excessive heat, and visible melting, I permanently removed the timer from service. I cannot say whether this was an isolated manufacturing defect or a broader quality issue, but I can say that this particular unit experienced a serious failure while being used within its advertised electrical rating. If you purchase this timer, I strongly recommend periodically checking it for excessive heat and discontinuing use immediately if you notice intermittent operation, unusual warmth, a loose connection, or any signs of melting. Safety was the primary reason I purchased this timer, so this experience was extremely disappointing.

Me encanta que sea mecánico y funciona de maravilla. Pero acomodaron en forma inversa los tiempos y hay que darle la vuelta completa para cargar sólo 2 horas. En lugar de empezar el reloj por el lado de 13 horas debería de empezar por 1 hora y así seleccionar el tiempo que generalmente es menor lo que uno necesita

Simple to turn and shuts off easily. Used on a Scooter charger as to not let it stay on overnight an have constant power to the unit.

After purchasing my wife an E-bike and reading the manual one of the things they tell you is not to leave the charger on more than 12-24 hours. So this timer I plug into the outlet and plug the battery charger into the timer. When the E-bike needs a charge I simply plug the cable into battery and turn the timer to 12 hours or more and no worries about leaving it plugged in too long! Highly recommend this timer for this purpose!

I do red light therapy, so I have red lights and a space heater on. I sometimes leave, and leave the lights on thinking I'll be back shortly, but sometimes I don't come back for a while. I might leave the heater on, forget it's on, and turn a different heater on and blow a breaker that can't handle two heaters. I have a push button countdown timer with a three-outlet splitter that handles the heater and two lights. Programmable timers are terrible for this type of thing, because I have no idea what time I'll want to do red light therapy, and I definitely won't want to do it at the exact time on different days. I was worried about relying on my single countdown timer - what if it fails, or what if I need a countdown for something else...so I got this 12-hour mechanical countdown timer. I bought the mechanical timer because it has the highest countdown and the most precise time. It's noiseless, which was what I wanted. It's better for relaxing, not to have a timer clicking constantly. That has the drawback of not knowing if the timer is working, but I tested it with a light and it worked, twice. Programmable timers are easy to find, and great if you need lighting on a regular timer for plants or Christmas lights. But when you just want to use power at random times and turn it off, programmable timers take time to set and get to be a nuisance. Great to know that I can find a good countdown timer somewhere.

I need to put a heat pad on my back to reduce the pain to help me fall asleep when I go to bed. It should not last more than 15 to 20 minutes to avoid the skin being burnt. I use lowest heat setting and it was okay when sometimes I did fall asleep before I remembered to turn it off. But if it were on higher settings I would have burnt my skin as the heat pad shuts itself off automatically only after 90 minutes which is much too long. With this countdown timer I don't have to worry about forgetting turning it off. It didn't work when I first tried it using common sense without reading the instructions. Then it works after I read them. But they should have pointed out that the instructions are just for the first time but they sound like every time you have to do all the steps which are quite cumbersome. I found that after everything has been plugged in the power source and the timer mode is set, what you have to do is to turn the dial clockwise to line up the countdown time with the arrow head. Then turn on the device you want to use (I have to do this for my device. You may not need to do this for yours). So, it's extremely simple to use. That's why I gave it a 4 star so that they can improve it by adding a bit more explanation in the operating instructions.
