CoolFire USB Solar Watch Charger Overview 

Great review. Good product. I'll always be able to depend on it. I'd rather have it and NOT need it than to need it and NOT HAVE it. Peace of mind is everything. It's a great product to help charge your solar watches fast.

I’ve had cool fire led light for a good few years now and I have perhaps neglected some of my solar watches by leaving them stored away for months at a time with no light source, this product helped me jump start the batteries essentially instead of leaving it on a window seal for hours on end. It seems to charges it pretty well and often will now top up my watches I’m not using every month or two and they all run great. Having a watch collection often makes it difficult to rotate through them all to charge whilst wearing

I'm in Scotland, so useful for me. TY

You answered my question in the first minute.

Thanks for this.. I bought a Coolfire watch some years ago (2019) off Amazon and they sold an LED booster at the same time but nothing like this in your video. it is just a slim black disc with LEDs .. rather like a large 44mm diameter coin 7mm thick.. it plugs into a USB port too. I put it in a drawer and forgot it.. LOL.. We are not known for all day sun in England but I just got into the habit of leaving the watch in a brightest part of the house when not wearing it.... I just dug the booster out and giving the watch a boost. the battery signal always appears to be charged the way I have used it till now.

Interesting, was considering making an auto-charger device to keep my watch "topped up" - thx for the info!

I have one and it works far better than I thought it would. I have 9 solar watches.

I don't have issues sunny all year round 😅

my GWG Casio Mudmaster 2000 showing L Battery sign , although it is in display box still didnt get charged much , thinking of buying this , thank you for a detailed review .

I live in Việt Nam where have sunlight all day in year,i put my solar watch on the rooftop, and it will have a fylly charge in 5 hours

I just used my LED camping lamp plugged into USB power and charged 4 watches at once, seems to work so I'll hold off buying this as I just needed to top off my watches in the winter months maybe a couple times or less, seems expensive 35+10 shipping. If this was mass produced in China, it'll be like $15 tops with all the LED and USBs readily available in that country, the chassis would be the only unique piece to produce. Great device though I almost bought one just bad price. Great review none the less.

Thanks for video. I work nights so my watch never sees the sun. The watch as been dead for about 4 years now so going to get this and give it a try

I paid over £40 for this from Amazon,I think a realistic price would be around £15,it’s a tacky plastic Chinese mass produced gimmicky piece of kit,but to keep your watches topped off it has its uses,but I do agree with the video saying about high powered torches for a quarter of the price would do the same job,but I’ve got it now,so may as well use it.

On a related note, I’d love a review of the nighthawk!

I’m not getting the charger but I did just order a watch case similar to yours. I have a collection of eco drives that would be perfect

It's better to have & not need than need & not have one of these watch chargers, especially on cloudy or rainy days as well as long winter nights!

It will heat your watch up. Not by that much. If I leave my on the charger for two hours, it’s faintly warm. I usually only use it for a couple of hours. I’m into watches so…

I had one and the LEDs started to fail quite quickly. I switched to using a video light (LED), which was more effective, although it also cost more. The Coolfire is poorly made in my opinion.

Unbelievably overpriced. A standard multi-LED torch placed on top of the watch will do the same for less than half the cost. No heat either.

Hello watchify, did you ever tryed a UV-Flashight expl. Nitecore Tube UV ? They have 365 nm wavelength, maybe that work also. And that lights are usealble also for other things. Its only an idea....😊😊😊

Thank you

It works well on cloudy days.

Can we put screen protector to solar watches ?

I suppose it would be good if you lived somewhere where you don't get a lot of sun, but I think it might be a bit of a gimmick. Appreciate showing something different though.

This reminds me of the canned air in “Spaceballs” for some reasons. Just so pointless, it’s ridiculous.

This is somewhat handy when you're working on a night shift I guess?
