CoolFire - Type-C UV Free Solar Watch Fast Charger for All Eco Solar Watches for Men, Reloj Hombre Portable Battery Charger. for All Kinds of eco Solar Watches. (Black)

Fantastic little item, charged up my casio mudmaster and citizen eco drives, easy to set up, easy to use, and actually works. Doesn't over heat, 2 different pad sizes for different watches, well worth buying

This Coolfire Solar watch charger is a life-changer. Being almost housebound due to mobility problems it has become well-nigh impossible to keep my Citizens Eco Drive watch charged properly. My flat is on the ground floor and only gets good sun exposure early in the day - I was struggling to keep watch charged on windowsill on dull days and eventually gave up. I then tried placing it within inches of a 100 watt (LED equivalent) lightbulb for hours/days/weekends/a week to top it up. If I forgot to do this for say a month or so the battery was in danger of dying on me. The movement of the hands changes to warn you the battery is very flat - the second hand jumps irregularly instead of moving smoothly. A couple of times watch stopped completely before I noticed it was doing this. Watch then began to spend more time almost affixed to the lightbulb than on my arm as I was scared I'd lose my favourite watch. Since October 2023 when I purchased this Coolfire Solar watch charger I have a much easier way to keep the battery topped up. I set the timer on my Kindle Fire for 8 hours, I place my watch on my solar charger, I plug the charger into mains power, start the timer on kindle, get on with my day until timer beeps. I switch off the power to the charger. Boom, I have my watch battery charged. I repeat the above about every week to 10 days to make sure there's always enough power in the battery to prevent it getting completely destroyed. Try it, buy it, save yourself a lot of hassle keeping your solar watches running for years. Get them out of storage and on to a charger just to keep them all alive - especially if you stay in Scotland like me and cannot always trust the sun to be bright enough to keep the battery working 100% all year round.

Pleased with this product and at this time of the year in the UK it allows the watch to function

I came across this item by chance. As a person who collects watches and has a number of Eco Driver ones that charge by sunlight I have found this device very useful. As someone who lives in an area with very little sunshine - particularly in winter - and who keep their watches in covered watch cases charging is an issue. I have two different size Eco Drive watches and this item comes with different size rings to suit whatever watch you are charging. 12 hours charging your watches using this item gives 6 months of power. Straight forward to use. Probably of limited value if you only have one or two watches but in my case a God Send.

Neat effective and I like it. There are two rubber attachments for different size watches the fit isn’t quite perfect but it’s certainly good. There is a little light leaking but not enough to bother me. There is a bit of residual heat in the watch but is dissipates quite quickly. Overall a pretty neat gadget, I’d repurchase as a stocking filler for Christmas!!!

Works well

My hubby has a Solar charged G Shock watch. When he needs to charge it he was having to leave it on the windowsill for a couple of days to re boost the battery. It was even longer in the winter months. I was mooching on Amazon and came across this. I’m so pleased I bought it for him because it’s brilliant. It runs on usb and you just plug it in and place your watch ( face down) on top of the unit. It’s a nice dinky thing so doesn’t take up a lot of room. My hubby usually pops it on for about 8 hours and then his watch is fully charged. The watch battery then lasts several weeks. Your watch face does get warm when charging but this soon cools off. It’s sooo much quicker than having to rely on actual sunshine. And because there’s no actual fittings it would fit any solar watch. I think this is such a great idea and would definitely recommend to anyone looking for something to charge their watch in quick and reliable time.

It works well and will take a g-shock solar watch from low charge to the start high charge in a few hours as opposed to days of strong natural light (rare in the UK winter if you work most of the day inside). However, the charge does not ast as long as with natural light - I was back to low battery in a couple of weeks. Easy to use, good price, lightweight & sturdy. Very little heat comes off it as well. Exreme brightness Cable is not a usb to c type as originally stated but a usb to micro not that it matters as comes with the cable

this item seems to work fine to charge my Citizen watches (I have 12)... if your watch doesn't have a charge meter it's hard to tell how fully charged the watch is so a review is difficult, however, I would recommend this unit if you wear your watch all the time and don't have time to leave it in the sun once in a while (especially in snowy winter)

Den är effektiv i att ladda, gör helt klart vad den är tänkt att göra, men den genererar betydligt mer värme än vad jag fått uppfattning att den skulle. Inte så klockan får skador, men mer än vad som känns helt tryggt. Jag skulle inte ladda mer än 4-5 timmar i streck

Funciona perfeitamente, tem excelente qualidade, muito prático. Vale o que custa pois a satisfação é certa.

Es un poco caro pero lo gana en calidad es muy útil para los relojes solares como el citenze eco draiver

Buen producto
