Review: Solar watch charger - 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
Review: Works well with watches of 38mm or larger diameter - There are devices that keep automatic watches fully wound when they are not being worn and now there is one to recharge solar watches off the wrist; it is the "CoolFire Solar Watch Fast Charger (compatible with all kinds of eco solar watches) 1046". Getting sufficient light onto a watch-face during the darker months to add to its current charge state is a perennial problem and necessarily involves artificial light sources, most of which emit varying levels of heat that could seriously damage the watch's internal components if sufficiently close (halogen and filament bulbs are the worst); at best, when too distant, charging can be exceedingly slow and need many days. Even with cool- or cold-running CFL or LED bulbs, 24-48 hour charge times are typical and may not then fully charge a watch. The LEDs used in this are a true cold light source and 22 of them produce a strong white light. Power is via a USB cable which may be connected to a computer or a mains USB plug adapter. A co-axial jack socket is a possible power provision option but the enclosed leaflet neglects to mention it but presumably also requires 5v at 2A. Not all solar watches are equal and some charge more quickly than others. The instructions for different watches may include charge times under various lighting conditions. According to the manual for a certain Citizen watch, 20 hours is required for a full charge at 100,000 lumens (bright full sunshine) and 60 hours at 10,000 lumens (cloudy, overcast day). For another Citizen watch, 11 hours in full sunshine is suggested confirming variations among Citizen's watches and other brands may have similar variations. With 40,000 lumens supplied by this unit, 36-48 hours may suffice for a top-up charge sufficient for up to 60 days' use although considerably longer than the 10 hours suggested by a previous reviewer for a full charge. A watch with a charge indicator (recharged only a week or two ago) may be allowed to run down almost to empty to gain an accurate full-charge time. Citizen use overcharge protection devices to terminate the process once the power reservoir is full; other brands may not. The unit is sufficiently small to fit on a bedside table, a small area on computer desk etc provided that there is at least a nearby mains socket or computer; some audio devices have USB charge ports for just such a situation. A power bank is yet another power source option. Other than the unit and USB lead, two soft rubber watch supports/masks are included to respectively suit watches of around 43 mm and 38 mm diameter; there is no specific provision for small-faced ladies' watches and some light leak will occur unless further masked in some way. The unit is light but unstable as the length and weight of the USB lead tend to drag it but with a weighty all-metal bracelet watch mounted it is perfectly stable. Lightweight poly-carbonate watches with silicone, nylon or fabric straps may be a problem unless extra weight, e.g. several large coins, is placed on the back of the watch. This charger is faster, brighter and more efficient than the CFL desk lamp first used or the LED one later used, both with lamp-to-watch distances of around 15-18 cm and typically for up to 48 hours, sufficient for at least 50% charge levels in most instances. There is an option to insert two AAA batteries via the base and then to use it as a super-bright torch or emergency light.

## 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.
