KWANWA Alarm Clock, Digital Clock Battery Operated with Big 1.2'' LED Time Display,Adjustable Brightness,12/24Hr,Portable Cordless,Alarm Clocks Bedside for Travel/Wall/Shelf/Desk (Blue display)

This is a brilliant battery-powered digital alarm clock.In some ways this is quite an ordinary bedside type alarm clock, with a reasonable display, reasonable price, and OK time-keeping. But there is one thing which makes this clock exceptional - the fact that it is powered by 4 AA batteries!My application is somewhat unusual - I play in a band, and I wanted a battery powered clock with large, easy to see digits to put on my pedal board, so that I can see how long we have been playing, and how long to go until it is time to stop (some venues have quite strict curfews imposed by the local council, so stopping on time is essential if you want to be re-booked!). There are plenty of small clocks out there which fit the bill, but most are either mains powered, or require a button to be pushed to see the display!This clock has a big, clear, easy to read display, which is ALWAYS ON! The batteries are claimed to last a year, which is amazing! I had the original batteries in for 6 months, and they seemed perfectly OK, (with perhaps a very slight dimming of the display), however, I changed them as a precaution. However I have no doubt they would have gone on for much longer!The clock has an "auto-dim" mode, which dims the display slightly from (I think) 8 PM to 8 AM. This is probably quite useful if you use this as intended, as a bedside clock, but for my purposes I don't need this. I simply set the time 8 12 hours fast or slow, so that the display is at its maximum brightness at times when I need to use it!It is small enough to fit on my pedal board, the display is always on and timekeeping seems to be reasonable, with the clock gaining about 1 minute over a 6 month period.In summary this is an averagely good bedside (or pedalboard) clock, which is made exceptional due to its battery power, always on display, and long battery life!

Excellent little clock. Very easy to read, and also quiet too... no ticking!

This free-standing, cordless, battery-powered alarm clock is sleek, modern, no fuss and feels robust, despite its basic plastic housing. It came packed in its own sturdy box and was well-protected against scratches and other damage.I quite like its chunky design. The red digits are larger than on my previous alarm clock and are very clear. The LED display is bright enough to be read easily during the day but, at the same time, not so bright that it interferes with sleep. The brightness can also be adjusted - there are 3 levels of brightness and I have set mine at level 2. The default for the colon between the hour and minute digits is set to blinking but, if this is distracting, the flashing of the dots can be switched off and the dots will display without blinking.One single alarm can be set and the clock has a snooze function. The alarm starts off at a fairly low volume, which I like, and gets louder as time progresses. The clock itself operates silently and cannot be heard ticking or humming.Unlike similar-looking USB-powered alarm clocks, the display of this alarm clock stays on permanently. This was the single most important point for me. I had tried several USB alarm clocks previously and the display on all of those switched off after a few seconds, unless the USB was plugged into the mains (a power bank did not do the trick). As the alarm clock cannot stand next to my bed and there is no socket within reach to connect the clock to the mains, I would have to make a fairly loud noise (not ideal whilst your partner is sleeping!), or get up to touch the snooze button, if I wanted to see the time in the middle of the night. With the Kwanwa alarm clock, I do not have this problem, as the time is always visible - day and night.On the negative side, the battery compartment on my alarm clock is very snug. It is so tight that the 4 AA batteries push up against each other and form a pyramid shape before they literally launch themselves out of the clock. It was tricky to keep them in place with one hand, whilst clicking the battery door in position with the other - they kept escaping. Even with the battery door secured, the batteries want to push out, so the battery door is bending outwards and there is a small gap between the door and the clock itself. It is a bit annoying but cannot be seen from the front.I do not know how long the clock will operate before the batteries need to be replaced. Currently, I am using single use batteries but will switch to rechargeable ones in the future. The clock was bought about a month ago, has been in use ever since and so far no regrets.

I love this little alarm clock, I wanted something that would run on batteries, and just give me the basic functions of a simple alarm clock, I like that it has the option to use the top touch sensor as a snooze button, or to turn the alarm off, and as I don't use snooze I just have it set to turn the alarm off, it has a nice large time display, I have the red clock display and even the lowest setting is quite bright at night, but I haven't found that it is too bright when going to sleep, I like that the 2 colon dots can be set as either solid or flashing, and the alarm sound increases over time, you also have the option for 12 or 24hr display, and most importantly it keeps perfect time, I set it to the time on my phone and so far it has kept to the second.I would highly recommend this alarm clock to anyone.

This clock is fantastic! The display is bright and easy to read, even from a distance. It keeps perfect time, and the adjustable brightness is very useful. Simple, sturdy, and reliable—highly recommended!

Great product

Received this clock yesterday and was very easy to set up. Nice size white numbers. It comes with 3 levels of brightness. So last night I found it too bright in the dark and tried it on the lowest setting. It didn't make any difference. It would seem I only have 2 settings. So obviously faulty. Will be contacting amazon about a replacement. Clock came with no specific packaging. Just bubble wrap around the clock in a plain brown box. Could have been someone had previously returned it as faulty. It's a shame as its a nice small battery run clock. Perfect size and great number display. Not happy though to have received another faulty item from amazon though.
