Trusted by over 300,000 customers worldwide, this portable charger is the ultimate solution for maintaining your solar watch’s battery life regardless of sunlight availability. ## Description CoolFire Solar Watch Charger is compatible with all kinds of solar watch. The solar charger uses cool LED lamps as electric light source to charge all kinds of eco solar watches. It is the most safe and easy USB electric light source for the charging of your sophisticated/expensive eco solar watch. Charging your eco solar watch under direct sunlight or conventional electric lamp may easily overheat your sophisticated solar watch. Expose to sunlight UV can fade the dial and hands of your solar watch. Overheating due to over exposure to direct sunlight or too close to conventional electric lamp could damage attachments on watch face as well as the watch movement. Sunlight is the best light source for the charging of your solar watch but it not 24-hour x 365 days available. Electric lamp charging can heat up your solar watch when it is placed too close to the watch. If you place your watch not close enough to an electric lamp, then the charging time will be much prolonged. The CoolFire Solar Watch Charger delivers light strength similar to a direct sunlight in summer, but it never heats up your watch. There are two soft rubber caps included for Men and Women solar wristwatches placement. It works for all solar watch Brands. That is powered by USB or DC4.5V AC Adapter. *CoolFire Solar Watch Charger is tested before shipment* By TimeChant (Hong Kong) Limited Review: Just works! - 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.

Just got the g-shock gravitymaster and feel overprotective!** A: No, it does not heat up watches. In fact, your watch will feel no different from the temperature it was at when you placed it on this charger. I have a new G-Shock watch and it works great for charging mine to the max. **Q: Anybody charge a g shock gravity master with this? GPW 1000** A: I have used it on all of my solar battery watches that includes "all" Casio g-shock Master of G series and all of their Solar Tough squares as well as my Citizen Eco-Drive solar powered movements. The unit provides a 30,000 LUX light power output which charges to full capacity between and 1 and 4 hours. My Rangeman took 9 hours but that was the only exception. **Q: Does any direct Led light will be sufficient in doing this charger job ?** A: I think any high intensity led would work. Since I have six solar watches I DIY'd my own lightbox using a usb rechargeable high intensity led bicycle handlebar headlight much like this one: https://smile.amazon.com/dp/B018YU370M/ref=sspa_dk_detail_1?psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUFQQVlSS1pIQkxXUTYmZW5jcnlwdGVkSWQ9QTA4NDE2MTExUEhXNFVPV0dZSzdMJmVuY3J5cHRlZEFkSWQ9QTAxNDMyMTBYOVBRNjAzRjQ2U1kmd2lkZ2V0TmFtZT1zcF9kZXRhaWwyJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ== Except mine had a little more lumens and it was cheaper, a total of seven bucks...ebayed it from China. This way I can charge all my watches at the same time using only this one bicycle headlight. What I like about the bike headlight is that it has a special lens that evenly distributes its light throughout its focus without hot spots so all my watches receive the same amount of very intense light. Also it was a lot cheaper than this one-at-a-time light charger and I can do all six of my solar watches at the same time. **Q: How long does it take for it to fully charge a Citizen eco drive Promaster Tough watch?** A: If it doesn't have a gauge then you truly cannot determine if it's fully charged: but, if the second hand's not jumping two seconds at a time, the watch is fine. My Tough doesn't have a gauge but my other Citizen does and I keep both of them exposed to the same amount of UV light so when the gauge is reading full on one, I know my Tough's good to go. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Just works! *by K***R on 29 January 2024* This Coolfire Solar watch charger is a life-changer.
