## Description

CoolFire The solar watch charger is compatible with all kinds of solar watches. The solar charger uses cool LED lights as an electric light source to charge all kinds of eco-friendly solar watches. It is the safest and easiest USB electric light source for charging your sophisticated/expensive eco solar watch. Charging your eco-friendly solar watch under direct sunlight or a conventional electric lamp can easily overheat your sophisticated solar watch. Overheating due to excessive exposure to direct sunlight or too close to a conventional electric lamp could damage the fasteners on the watch face as well as the movement of the watch. Sunlight is the best source of light for charging your solar watch, but it is not available 24 hours a 365 days. Charging the electric light can heat your solar watch when placed near the watch. If you place your watch not close enough to an electric lamp, the charging time will be much longer. The Coolfire solar watch charger provides light output similar to direct sunlight in summer, but it never heats up your watch. There are two soft rubber caps included to place solar watches for men and women. Works for all brands of solar watches. Powered by USB or DC 4.5V AC adapter. *Coolfire Solar Watch Charger is tested before shipping* by TimeChant (Hong Kong) Limited

Review: good item - 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)
Review: Gör det den påstår… - 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

- 30,000 lux output power light (similar to direct sunlight, but does not overheat the watch).

## Questions & Answers

**Q: Does this lamp/light heat up the watch in a harmful way? 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.

### ⭐⭐⭐⭐⭐ Muy buen dispositivo
*by A***A on 25 July 2024*

Excelente dispositivo para cargar los relojes, si que se maltraten por los fuertes rayos del sol, lo deje toda la noche cargando después de que estaba totalmente descargado y el medidor indica que se cargo casi 3/4, lo deje otra noche y se cargo al 100%
