Fosmon 24-Hour Digital Timer Outlet (2 Pack) Review: Quiet, Simple Timers for One Daily Schedule

Fosmon's digital timer outlets plug into a wall socket and switch whatever is plugged into them on and off on a daily schedule. This two-pack gives you two timers, each with an LCD screen, one on and one off time per day, a MODE button for manual control and a backup battery that holds the settings through a power cut. They are simple, quiet and compact. Before buying, check the plugs you want to use and how much scheduling flexibility you need.

TL;DRThe Short Answer: Is the Fosmon Digital Timer Outlet Worth It?

Silent, simple and small enough to tuck behind furniture, the Fosmon timer does one on and one off a day, and that is all. It suits a lamp, holiday lights or an aquarium on a fixed schedule, not a home that wants different times at weekends. Its polarized two-prong outlet will not take three-prong plugs, and some units lose their clock or fail within months, which is where having two in the box helps.

NoFussDeal rates the Fosmon Digital Timer Outlet 4.3 out of 5 at $19.99. Last updated September 27, 2026.

What Stands Out

  1. Two timers in the pack, each with its own daily on and off time.
  2. LCD screen with large, easy-to-read numbers and silent operation.
  3. MODE button switches the outlet on or off manually.
  4. Backup battery keeps settings for more than 100 hours without power.
  5. Rated 125V and 15A, for incandescent, CFL and LED lights, fans and more.
  6. Side-entry, low-profile design uses one socket, so two fit a standard duplex outlet.

Strengths and Drawbacks

What works

  • Quick and easy to set the clock and daily schedule.
  • Silent, with no ticking or clunking.
  • Uses one socket, so two fit a duplex outlet.
  • Backup battery holds settings through power cuts.
  • Two timers in the pack for two independent schedules.
  • Limited lifetime warranty.

What does not

  • Only one on and one off time per day, with no weekday or weekend options.
  • Polarized two-prong outlet will not take three-prong plugs.
  • Durability draws mostly complaints, including outlets that stop switching.
  • Some units lose the time and reset to midnight.

Features in Depth

01

One Daily On and Off Program

Schedule 24-hour, one on and one off Manual Override MODE button Display LCD with large numbers

Each timer runs a 24-hour schedule with one on time and one off time that repeat every day. Programming is where the Fosmon shines for ease: set the current time, set on, set off, and it runs, with large numbers on the LCD that are easy to read. For a single lamp in the evening, holiday lights, patio lights or an aquarium, that is all you need, and many people like it precisely because it is a simple one-event timer. The limitation is flexibility. There is no weekday and weekend split, no second on and off period in the same day and no random mode, so anyone wanting lights to come on in the morning and again in the evening, or to vary through the week, will outgrow it. The MODE button switches the outlet on or off manually when you need to override the schedule.

Polarized Outlet and Load Rating

Rating 125V, 15A Outlet Polarized two-prong Certifications ETL, FCC, RoHS

The timer is rated 125V and 15A and works with incandescent, CFL and LED lights, as well as lamps, fans and similar devices. Its outlet is polarized two-prong, meaning one slot is wider than the other to match polarized plugs and there is no ground hole. Fosmon notes this reduces the chance of electrical shock, but it also means three-prong grounded plugs will not fit, which rules out many space heaters, some fans and most computer equipment with a ground pin. For heaters, even ones with two-prong plugs, running close to a timer's maximum load for hours is hard on any small plug-in timer, so a lighter load gives it the best chance of lasting. The timer is certified by ETL, FCC and RoHS and is meant for indoor use.

Compact, Silent Design

Sockets Used One Plug Design Side-entry, low profile Timers in Pack 2

The timer occupies only one socket, and its low-profile, side-entry design means you can fit two timers in a standard duplex outlet or leave the neighbouring socket free. That also makes it easy to use behind a sofa, bed or cabinet, and size is one of the most praised points. The digital mechanism is silent, a real improvement over clockwork dial timers that tick audibly and clunk when they switch, and it matters most in bedrooms and living rooms. The LCD numbers are large enough to read at a glance. With two timers in the pack, you can run two lamps or light displays on independent schedules.

Backup Battery, Timekeeping and Reliability

Backup Battery Holds settings 100+ hours Warranty Limited lifetime Use Indoor

A backup battery keeps the settings in place for more than 100 hours when there is no power, so a typical outage will not wipe your schedule, and the batteries arrive charged. Timekeeping is still mixed: some timers hold the time well for long periods, while others reset to 12 a.m. every few days, which leaves lights running on the wrong schedule until the clock is set again. Durability draws mostly complaints, and the most telling failure is a timer whose display and buttons still work but whose outlet no longer switches power on, which one owner saw in one of four units after about a year of light lamp use. Another owner found a timer stored in a drawer would not light up until the troubleshooting reset brought it back. Fosmon offers a limited lifetime warranty with USA-based customer service.

How We Scored It

Based on
The manufacturer's published specifications and the product's live Amazon listing.
Owner rating
4.4 out of 5 on Amazon, recorded September 27, 2026
How we score
We score each thing that comes up most in owner feedback on the Fosmon 24 Hour Programmable Digital Timer. Eight things come up most in owner feedback: three draw praise, four split opinion and one draws mostly complaints. Its ratings average 4.4 stars (74% five stars, 12% four, 5% three and 9% one or two), so every score starts at 88, that average on a 100 point scale. Where opinion is split, we take off 6. Where it draws mostly complaints, we take off 12. Then we read seven owner reviews in full (every one we found gave it four or five stars) and move the score up to 5 points either way depending on how the owners who mention it rated the product. Our overall score starts from the same 4.4 star average and loses 0.1 for each thing that draws mostly complaints, with 0.1 more when at least a tenth of ratings are one star, never more than 0.3 in all. Here that takes off 0.1, which gives 4.3. Read our editorial standards

What Buyers Say

Ease of use, compact size and silent operation are the clear strengths: most people set the clock and schedule in a few minutes, and the timers tuck behind furniture without the ticking of a mechanical dial. Reliability, value, programmability and timekeeping are mixed. The single daily on and off time is enough for many and too limited for others, and some units lose the time and fall back to midnight. Durability draws mostly complaints, including units that stop switching power within weeks or months.

Setting It Up

  1. Check the plug

    Make sure the device you want to control has a two-prong plug. Three-prong grounded plugs will not fit the timer's outlet.

  2. Charge the backup battery

    Plug the timer into a wall socket so the backup battery stays topped up and the display comes on.

  3. Set the current time

    Follow the included instructions to set the clock on the LCD, checking morning and evening are correct.

  4. Set the on and off times

    Enter one on time and one off time for each day. The schedule repeats every day.

  5. Plug in your device

    Plug in the lamp or lights, switch the device itself on, and use the MODE button to confirm the timer is on its schedule rather than set to always on or off.

Common Questions

How many on and off times can the Fosmon timer hold?

One on time and one off time, repeated every day. It cannot run different schedules on different days or several periods in one day.

Will a three-prong plug fit?

No. The outlet is polarized two-prong with no ground hole, so it takes two-prong plugs only.

What happens during a power cut?

A backup battery keeps the settings for more than 100 hours without external power, so a typical outage will not erase the schedule.

Can I switch the outlet on or off manually?

Yes. The MODE button turns the outlet on or off manually, outside the schedule.

Can I use it with a space heater?

The timer is rated 125V and 15A, and Fosmon lists heaters among its uses, but many heaters have three-prong plugs that will not fit, and running a heater near the maximum load for hours is hard on any small timer. It is better suited to lamps, lights and fans.

How many timers come in the pack?

Two. Each has its own schedule, and both can share a standard duplex outlet thanks to the side-entry design.

The Verdict

4.3Out of 5

For switching a lamp, holiday lights or an aquarium light on and off at the same times every day, the Fosmon two-pack is easy to recommend on simplicity alone. Setting the clock and schedule takes minutes, the timers are silent, each uses only one socket, and a backup battery holds settings through power cuts. There are three things to weigh. Each timer runs just one on and one off time per day, so there is no weekend schedule or second evening period. The polarized two-prong outlet will not take three-prong plugs, which rules out many heaters and grounded devices. And reliability is patchy, with some units losing the time or failing to switch power within months. With two timers in the pack and a limited lifetime warranty, they are good value for simple jobs.

Who should buy it

  • Lamp and holiday light schedulers
  • Anyone who wants one fixed daily on and off time.
  • People who dislike the ticking of mechanical timers.
  • Aquarium keepers with two-prong tank lights.

Who should skip it

  • Anyone who needs different schedules on different days.
  • People controlling devices with three-prong grounded plugs.
  • Anyone running heavy heaters for hours at a time.

A silent, easy-to-set pair of timers for simple daily schedules, as long as your plugs are two-prong and you can live with patchy reliability.
