CoolFire (The Original) - USB-C UV Free Solar Watch Fast Charger for All Eco Solar Watches. Safe 24/7 Charging (No Timer Needed). Reloj Hombre Portable Charger. Fits G-Shock, Citizen, Seiko, Garmin SV

This is a bright light that charges battery watches that are solar charged i bought a new watch and needed to charge it it was almost out of power this charged it right up and charges the luminus hands and minutes markers every five mins when charged they stay illuminated quite some time the light has two rubber guards mine came with only one but that could be due to packing it doesnt charge faster than sunlight but sunlight when shining does make my tag heuer watch quite hot this makes it slightly warm so i feel its less harmful so never going to have issues on cloudy days its worth the money if you have a solar powered watch I would recommend this if your worried about your expensive watch getting to hot directly from the sun tags aren't cheap but great watches and I aim to have it my entire life whuvh is short due to copd but I wanted an accurate watch alteast once in my life my old gshock watch I threw away because the battery went flat and wouldn't charge by sunlight in the winter I wish I had this to recharge it by mistake but life's full of learning curves I would definitely recommend this item worth every penny

Absolutely brilliant.Used for my Citizens and really impressed.

Well, mine doesn't have a button or an option to insert batteries, but it seems to work OK.

Smaller than I thought, but really powerful, charged my solar watches to the max within a couple of hours

Efficace, recharge bien les montres solaires. Sans chauffer exagérément ; il manque juste un interrupteur, un timing de 8 heures.

Spełnia swoje zadanie. Ładuje moje zegarki Casio. Jednak trochę się nagrzewa, nie jest tak że wcale się nie grzeje, ale myślę że nie jest to na tyle duża temperatura by uszkodzić jakiś zegarek. Wydaje mi się że gdyby ładować na bezpośrednim słońcu to o wiele bardziej by się nagrzał. Po za tym super produkt. Polecam

Works well, easy to use-simply plug in a usb-c cable/power source and place your watch face down on it. You do need to pay attention to the amount of time, there is no off switch or automatic anything! You are the timer. I’ve used it for four to six hours, and I’ve used it overnight 10+ hours. It and your watch do get warm! Rather powerful lumins output and even for LEDs that means heat. Build quality is okay for an all plastic unit. Longevity is yet to be seen. Really good, no frills, solar/light charger for a really reasonable price. It does NOT come with a wall wart, power cube, whatever you want to call it, just a power cable and the light device or charging base. Oh, and two different size rubber grommet like rings for different size watches. Simple - Does what it supposed to do.

Ottimo prodotto. Non scalda e in poche ore ricarica bene un orologio solare da carica media a carica massima.

Great product.
