The Best Projection Clock: Our Choices

Guide: Questions you should ask yourself before buying a projection clock

What is a projection clock?

In general, a projection clock is a clock like the ones you know from your bedside table, but with the additional function of projecting the time onto a surface. In principle, it works like the well-known slide projectors.

This useful additional function may make your life easier in the early hours of the morning. Maybe your bedside table is lower than your bed, so you have to lean down every morning to read the time.

With a projection clock, the time is projected visibly in one place without you having to move around a lot when you wake up.

A projection clock, as a modern home gadget, is certainly also a highlight in your four walls.

What does a projection clock cost?

Inexpensive projection clocks are available for as little as 10 euros. The price range is about 10 - 50 euros, but there are also projection clocks that cost more than 50 euros.

Of course, the price also depends on the brand of the product or the quality. The price is often used as an indicator of quality.

However, additional functions, such as a radio function, a temperature display or an alarm function, are also decisive for a higher price. The price for a projection clock with these functions is around 30 euros.

What alternatives are there to projection clocks?

Alternatives to projection clocks are, of course, conventional bedside clocks: Radio alarm clocks, analogue clocks or radio clocks.

Regardless of the general benefit of a clock: the time display, a projection clock can promote convenience.

Alternative
Analogue clock Analogue clocks are conventional clocks with hands and a dial. They are also available as alarm clocks.
Radio alarm clock Radio alarm clocks are clocks with a digital clock display where it is possible to be woken up with a radio station.
Radio clock Radio clocks are available in analogue and digital display versions. The great advantage here is that the clock can set itself automatically.

Where can the time be projected?

Projection clocks have a small integrated projector that projects the time onto a surface. Similar to a slide projector or a beamer, the projection can be adjusted variably.

The integrated mini projector can be adjusted/rotated so that the time can be projected onto any surface, be it the wall or the ceiling.

Is there a projection clock with weather station?

Projection clocks are also available in combination with a weather station. Weather stations have the function of measuring and displaying the indoor temperature, but also the outdoor temperature.

Apart from the time and temperature, some models can also display the humidity and the complete date.

It should be noted, however, that these projection clocks can usually only project the time onto a surface, but not the other displays.

Does a projection clock have a power supply?

Another question you might ask is whether a projection clock runs on batteries or is powered by a mains adapter. According to the research, there are both variants.

Projection clocks are either powered by batteries, usually type AA, or by a mains adapter. Depending on the location of the projection clock, it is important to consider whether a power source is available.

But it is not only the location that should determine which of the two power supply alternatives makes more sense.

Convenience also plays a role here, because with a continuous power supply you don't have to worry about the clock switching itself off when the batteries run out.

Decision: What types of projection clocks are there and which is the right one for you?

To help you decide, here is a summary of the types of projection clocks. In principle, there are four types of projection clocks:

  • Radio projection clocks
  • Radio projection clocks
  • Analogue projection clocks
  • Multifunctional projection clocks

Depending on the type of projection clock, they have different advantages and disadvantages that may help you in your decision.

The main differences between these types of projection clocks are the operating mode and the type of display. The projection itself is the same for all four types.

Depending on the features of the clock, there may also be models that combine the features of different types (e.g. radio alarm clocks with radio, analogue radio clocks)

What distinguishes a radio-controlled clock and what are its advantages and disadvantages?

In general, a radio-controlled clock is characterised by precise time indications. Compared to other clocks, these receive radio signals and are set by radio. This means you no longer have to set the clock manually - it sets itself.

This practical function also ensures that the clock automatically adjusts to summer or winter time.

The current date can also be displayed by radio signal, so radio-controlled clocks usually have a date display at the same time.

Advantages
  • Exact time
  • Automatically adjusts to summer/winter time
  • Usually also with date display
Disadvantages
  • Malfunctions
  • Interference signals
  • Obstacles for radio waves

It should not be forgotten, however, that radio masts can also malfunction from time to time and display an incorrect time.

In addition, radio waves can be interfered with by signals from other devices or even the construction of your residential building (e.g. reinforced concrete building).

What are the features of a radio clock and what are its advantages and disadvantages?

It's nice to wake up to music or the weather forecast. This is possible with radio alarm clocks. They combine the alarm functions and the functions of a radio.

They usually have a snooze function - the radio alarm rings again every 5-10 minutes. This function reduces the likelihood of oversleeping.

Advantages
  • Wake-up with music possible
  • Preset alarm tones
  • Snooze function
Disadvantages
  • Signal interference
  • Consumes more power than a normal alarm clock
  • No automatic clock setting

Radio alarm clocks receive FM signals that can also be disturbed depending on the location. Since the classic radio alarm clock does not receive radio signals, it must be set manually.

What are the features of an analogue projection clock and what are its advantages and disadvantages?

The analogue projection clock has a clock face and hands. Depending on the model, a clock face is also projected. Analogue clocks are characterised by their easy handling and durability.

Depending on taste (digital display or dial), analogue watches are currently in vogue. They therefore have a certain cult factor.

The classic ticking of the watch can be perceived as a disturbing factor. In addition, there is no automatic clock setting. Analogue watches also do not have a snooze function.

Advantages
  • Easy to handle
  • Durable
  • Cult factor
Disadvantages
  • Often loud hands
  • No automatic clock setting
  • No snooze function

What are the characteristics of a multifunctional projection clock and what are its advantages and disadvantages?

Multifunctional projection clocks are combinations of a projection clock and a weather station. In addition to the time, these projection clocks also show the temperature, the date and often also the humidity.

Depending on the model, the data for temperature or humidity are measured at intervals (e.g. hourly). Therefore, it is possible that the data displayed is not up to date to the minute.

The multifunctional projection clocks available on the market only project the time despite many displays and are more expensive to purchase.

Advantages
  • Additional temperature display
  • Additional date display
  • Additional humidity display
Disadvantages
  • Projects only the time
  • Data is measured at intervals
  • More expensive

Buying criteria: Use these factors to compare and evaluate projection clocks

In the following, we would like to show you which factors you can use to compare and evaluate projection clocks.

This will make it easier for you to decide whether a particular projection clock is suitable for you or not.

In summary, these are:

  • Operating mode
  • Display type
  • Display/backlight
  • Batteries vs. mains supply

If you are still undecided about which model is best for you, you can use these buying criteria to help you decide. These are explained in the following paragraphs.

Operating mode

As mentioned above, projection clocks can be divided into four types: Radio projection clocks, radio projection clocks, analogue projection clocks and multifunctional projection clocks.

Depending on the mode of operation, they have different advantages and disadvantages. Depending on your intended use, you can find out which features of the projection clock types suit you.

Consider which features are suitable for your needs. Do you need additional displays such as temperature or date? Do you travel a lot and want to take a handy watch with you? Do you like listening to the radio?

Here is a brief overview of the operating modes and their displays and functions:

Operating mode displays and functions
Radio projection clocks analogue or digital time display, automatic time setting, usually also with date display
Radio projection clocks digital display, radio function, alarm function
Analogue projection clocks analogue time display with dial and hands, possibly alarm function, possibly date display
Multifunctional projection clocks digital time display, date, indoor temperature, outdoor temperature, humidity

Display type

In general, clock times are displayed either digitally or analogue. It is a matter of taste which version you prefer. Digital clocks show the time in digits, while analogue clocks show the time with hands and a dial.

Despite the cult factor of analogue watches, it should be mentioned that children, for example, read digital watches better than analogue ones.

Furthermore, analogue watches without backlighting may be more difficult to read in the dark, but the projection removes this obstacle.

For projection clocks with a digital clock display, you can pay attention to how large the displayed digits are. This may be a good tip for people who wear glasses and look at the clock in the morning without them.

Display/backlighting

Projection clocks with a display are available in two versions: a display where only the digits light up or a display with backlighting.

However, there are also projection watches on the market that have no display at all and only project.

Displays where only the digits light up are easier to read because they are immediately recognisable at a glance. Displays with backlighting usually have models that have several displays.

Another point to consider is the colour of the display or projection. At night, your projection clock may be the only light that shines.

Did you know that blue light makes you more alert?

Therefore, you should avoid projection clocks with blue light if possible. Green or warm white light, on the other hand, have a calming effect.

Think about which colour will not prevent you from falling asleep. Most projection clocks have a red, blue or green display and projection.

Batteries vs. mains power

Another decision point is the power supply. Projection clocks are powered either by batteries or by a mains adapter.

Models that are powered by batteries have the advantage that they are more mobile. When choosing a location, it is not necessary to consider whether a power socket is available nearby. Therefore, these devices are also more suitable for travelling.

The other alternative is a continuous power supply with a mains adapter. Here you don't have to worry about your device eventually giving up the ghost or the time possibly being falsified.

Facts worth knowing about projection clocks

Can I build a projection clock myself?

If you don't want to buy a projection clock but still want to upgrade your old clock radio with a projection function, you can also build a projector yourself.

However, there are hardly any instructions or explanatory videos online on how to build projection clocks.

Nevertheless, you can find countless instructions and videos online that show you how to build a mini projector or beamer for your smartphone yourself. You don't need a lot of technical know-how.

Maybe you could try integrating your conventional clock radio instead of your smartphone - but this would only work for clocks with an illuminated display.

What other colours are projection clocks available in?

The colour of the projection clocks offered depends, of course, on the manufacturer and the design of the projection clock.

However, you will find differences in the colours of the display and the projection colour.

The projection clocks on sale usually have a red, blue or green display or projection colour.

Can I buy power supplies for projection clocks separately?

Projection clocks are powered either by batteries or by a power supply unit.

Depending on the production of the model, the mains cable may be inseparably connected to the unit. In this case, power supply units cannot be purchased separately.

Did you know that radio-controlled clocks from all over Germany get their signal from Braunschweig?

There is an atomic clock in Braunschweig that can always tell the time precisely. This atomic clock then sends a radio signal to all radio-controlled clocks in Germany.

Other devices have the option of removing the power supply unit. It is also possible to buy a separate power supply unit.
