White : ChaoRong Battery Operated Only Digital Alarm Clock with 1.2" Large LED Display. You Can Place It Anywhere. 4pcs Batteries Can Keep the Time Display Day and Night for More Than One Year (White)

Works without electricity, directly on battery only, display time is easily visible during day and night.

I ordered the white Timegyro clock with 1.2" digital display in October 2022.Running on four AA rechargeable NiMH batteries, the clock needed fresh batteries after 10 months. Checking the state of the batteries, only one of them had a voltage around 0.5 V. The other three batteries were at about 1.2 V. Basically, the clock went black because I had one dud battery. With better luck, or just a randomly different battery, the clock could likely have run much longer without a battery change. In fact, I have another clock in a different color which ran for 15 months. I'm very pleased the clocks operate with a constant readout for 10 months and longer.The red digits are my preference as red is easy on the eyes and does not impair night vision if you look at the display from a very short distance (the reason military units use red lights sometimes). The clock has a sliding switch for three brightness levels, but they are essentially all the same. That said, the clock is readable across a dark room without shining like a beacon, and the clock is still easily readable in the daytime so long as it is not in the path of a sunbeam.The clock does not show seconds so synchronizing with a more precise clock is challenging. I only adjust the time by one or two minutes every few months, or less often, to keep it accurate.I'm happy with the clock and recommend it.

Tal como se ve en la foto. Es lo que yo buscaba, así que contenta. Funciona bien, es sencillo, a pilas, la luz me es perfecta para la noche. Buena compra.

Ich benutze den Wecker lediglich als Uhrzeitanzeige. Und die ist super, da sie nicht zu hell ist und nicht blendet. Die Weckfunktion habe ich jedoch nicht im Einsatz. Die ist extrem laut. Das ist vielleicht ok, wenn man alleine schläft oder wenn der Partner zur gleichen Zeit aufstehen muss. Ansonsten ist der Wecker einfach zu laut. Da fällt die andere Person auch gleich aus dem Bett.

I was tired on the clock on my bedside with the cords and blue light, so replaced with this clock. Smaller than I thought, but big enough to see across the room. Red numbers are supposed to be better for sleep than blue numbers. Keeping accurate time, so a good buy for me.

Perfecto si se busca un despertador que no sea necesario enchufar a la red (lleva 4 pilas) y se vea a oscuras (los dígitos están constantemente encendidos). Los números son grandes y una persona mayor los ve sin problemas. Pese a ser de color rojo, no molestan nada, tienen el brillo perfecto. De día se distinguen sin problemas también. Falta ver cuánto duran las pilas, pero tras 3 semanas encendido todo ok. Como única pega, las instrucciones están solo en inglés, pero es bastante intuitivo.
