The tradeoff: One wake-up time for every day, no bedtime light (the night light goes off by itself after 20 minutes), and no wall plug in the box.

Set this clock up

  1. Charge the penguin for at least 30 minutes with its USB cable before you first use it (the wall plug is not in the box), then slide the power switch on.
  2. Hold the clock button until the time blinks, set the hours and then the minutes with + and −, confirming each with the clock button, then choose a 12- or 24-hour clock.
  3. Hold the alarm button until the time blinks and set the “OK to get up” time the same way, leaving it on ON. From 30 minutes before that time the penguin glows warm yellow, and at the time it turns green. Any button switches the green light off.
  4. Tap the penguin’s head for the night light, which goes off by itself after 20 minutes; hold the head to change the brightness, and use the color button to choose a warm or a bright light.
  5. Hold the color button and the alarm button together to lock the buttons. With the lock on, the penguin still turns green even if the power switch has been slid off.

Luvion says to charge it only with the USB cable it comes with and never to put the penguin or the cable in water. Keep the cable away from the bed.

Features the maker’s manual doesn’t mention aren’t listed here, so the clock matcher won’t suggest this clock for them.

From 30 minutes before the wake-up time the penguin slowly glows a warm yellow, and at the wake-up time it turns green.

A nap timer and a nap wake-up time work differently. The planner keeps them separate.

Without Wi-Fi or a phone

It has no app and needs no Wi-Fi: you set and change everything on the clock, and it runs by itself.

Power, and what happens in a power cut

When your child outgrows the light

Luvion Penguin has no alarm sound, so a school-age child who needs waking will need another clock. When to move on to a kids’ alarm clock.

Check it in your home

While you can still return it, try the buttons you will actually use. These are checks for you to make; we have not tested this clock.

  • Find how to change the times and switch the wake-up light on, then check it shows the light and sound you chose.
  • Check the brightness, the volume and where the clock stands, using the maker’s placement advice. Check what the lock stops and which buttons still work.
  • Use the clock’s own preview or test, if it has one, rather than unplugging it or resetting it to see what happens.
  • Show the other parent, a grandparent or the sitter the buttons. Read what to do after a power cut before you need it.

Agree on what the light means and what to do if it does not come on, then keep the manual or the maker’s help page with your plan.

Show your child what this clock’s light means, and leave a note for the sitter.

If the light does not come on, check the time, the mode and the power before you reset the clock.
