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

Very happy with this white light charger for my citizen. Works perfectly. and will work perfectly when there is no sun.

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

Seemed like a good idea, so I bought one. Unfortunately my Citizen watch doesn’t have a battery charge indicator so I had no idea if this item actually worked. However, I had a garden solar ornament, with a small solar panel, that was struggling. So I put it on the CoolFire and ‘bingo’ it fully charged the solar battery. So now I use the CoolFire to charge my watch and small garden solar lights!!

excellent product for charging solar powered watches charges quickly I wouldn’t be with out it

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.

This little gadget does exactly what it says and it has saved my watch excellent from especially useful it will be through the dryer months.

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

Excelente. Super practico y comodo. Pequeño

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

Only used it on G-Shocks but to give you an idea of the speed; Frogman from one bar to full in about 2 hours. Rangeman (old style) from empty to full in 3 hours. New Rangeman (bluetooth) from reserve to full in 2 hours. Still have a few to charge but this thing is fast.
