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.

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 ### ⭐⭐⭐⭐⭐ Good no frills solar/light charger *by M***N on July 16, 2026* Works well, easy to use-simply plug in a usb-c cable/power source and place your watch face down on it.

Simple - Does what it supposed to do. ### ⭐⭐⭐⭐⭐ Bright and light *by L***P on June 15, 2026* Got this for my Citizen watch, works great and charges my watch very well. Great investment! ### ⭐⭐⭐⭐⭐ Just what I need. *by L***0 on May 2, 2017* I received my Amazon order for two of these chargers and I immediately tried them out. Each one can be powered in three ways: 1. Mini USB cable. 2. 4.5 V DC power supply. 3. 2 AAA batteries. When you use the AAA batteries, only four of the LEDs will light up. I don't know how well the four LEDs charge a solar watch because I only tested my chargers with the batteries to make sure that the battery terminals were making good contact. I never ran them for any length of time with the AAA batteries. For the long term test, I powered my two chargers with one of these Vivitar USB chargers that has two 2 A USB outputs: https://www.amazon.com/dp/B005GCMYAG/ref=cm_cd_asin_lnk Note that if you plan on getting a dual USB output charger similar to what I bought, look carefully at the current output through the two USB ports. I found that most of the units do not have a full 2 A output from both USB ports. Most of them have 2 A from one and 1 A from the second one. Ideally, you want as much current as possible (2 A) from both USB ports. The Vivitar one that I mentioned above was one of the few with that option. Despite what the Amazon reviewers said, I have had absolutely no problems with the one that I bought. The solar watch LED chargers are made from very thin black plastic and they are very light weight. I would not even think about taking them on vacation with me because I don't think that they'd survive bouncing around in a suitcase. They are plenty durable enough for what I intend to do with them though - sit on my dresser and charge up my Casio, Seiko, and Citizen solar watches once a month. I put two of my most favorite Citizen Eco Drive dive watches on the new chargers: my Eco Zilla and my Promaster Aqualand Depth Meter diver. Both watches rested on top of the chargers' rubber bezels without extending beyond the bezels' outer edges. The chargers' rubber bezels are great because they did not scratch my watch bezels. The LED chargers worked great! I have never run my solar watch batteries down very far (that will shorten the life of them) but my depth meter dive watch has a power reserve meter on it and it was down to about 75% charge before I started my test. After about three hours on the LED charger, the meter was up to a full 100%. Even though my two watches were fully charged up, I decided to leave them on the LED chargers for a full 24 hours. After sitting on the chargers for the full 24 hours, my watches were only a little bit warm and not dangerously so. This is a major benefit to using these LED chargers versus leaving solar watches on a windowsill where they can really cook. Also, unlike sunlight, LEDs do not give out UV light so they will not fade watch dials and hands. Fading hands is a big problem with some Citizen Eco Drive dive watches with bright orange minute hands if they are left on a windowsill repeatedly for recharging. The chargers come with two different sized rubber bezels. Supposedly one is for woman's watches and one is for men's watches. I only used the larger one for men's watches and it worked just fine. It was able to accommodate both my largest watch (the 50 mm Aqualand Depth Meter BN2021-03E diver that I ran my first test on) and my smallest watch (a 40 mm Citizen BN0000-04H diver.) Both fit just fine though the larger watch rested on the highest top surface of the rubber bezel, while the smaller one fit down low inside the bezel on its sloped/inclined surface. All of my other solar powered watches in between those sizes fit just fine on the chargers. When resting my large Aqualand Depth Meter and Eco Zilla watches on the chargers, the bumps on the surfaces of the bezels caused the bezels to not sit 100% flush against the chargers' rubber bezels all the way around. Those gaps between the watch bezels and charger bezels let some of the light from the LEDs shine out and into my bedroom. My wife complained about the light on the ceiling last night when she was first went to bed but after she shut her eyes, she fell asleep in a few minutes. She slept just fine throughout the night so the light spilling out from the chargers may seem like a lot at first, but once you close your eyes you won't notice it. My smaller watches like the 40 mm Citizen diver I mentioned before that fit within the bezel did not have nearly as much light spill out. Also, in theory, a watch bezel that is perfectly smooth will rest completely flush against the charger bezel and prevent any light from shining out and into the room. None of my solar watches have smooth bezels so I did not get the chance to test out that theory. So I give these little solar watch chargers two thumbs up. For what they are, they're not the cheapest things out there, but if they keep my solar watch batteries from going dead and keep my watch hands and dials from fading, they're a great buy. Some of the negative comments/reviews for these solar chargers say to just leave solar watches on a window sill to recharge them. Here is my reply to that idea: Putting a solar watch on a window sill exposes it to lots of UV light. That harsh UV light can fade the dial and hands if they are brightly colored, as are the minute hands on several of my solar diving watches. There are pictures on the internet of badly faded dive watch dials and hands from people that made the mistake of using a window sill to recharge their watches. Unlike sunlight, LEDs like what are used in this charger do not give out a lot of UV light (some sources say that LEDs do not put out any UV light) and thus they will not fade anything that they illuminate. Also, if you have a Citizen Eco Drive watch, the instructions clearly state to avoid charging the watch in an area that becomes hot like a car dashboard. A window sill in direct sunlight can easily become just as hot as a dashboard. Too much heat is not good for the movement in solar watches. Of course, you can just wear a solar watch to recharge it (unless you're nocturnal) but when you're a watch collector, usually you have too many watches in your collection and your solar ones only come up in the rotation every few months at most. As a result they don't get the necessary wrist time to sufficiently keep their batteries fully charged between the times that they are worn. Letting solar watch batteries die repeatedly will drastically shorten their life. As others have found out the hard way, these chargers will not fix a completely dead rechargeable battery in a solar watch. ## Frequently Bought Together - CoolFire - UV Free Solar Watch Fast Charger for All Eco Solar Watches for Men, Reloj Hombre Portable Battery Charger, for All Kinds of Sophisticated Eco Solar Watches (Black) - ECEEN Solar Watch Charger, 8H Timing Off with Men, Women & Square 3 Caps, LED UV Light Fast Charge Eco Driver Watches Compatible Casio/Tough/Protrek/Seiko/Citizen/Garmin/Timex/Bering/FANMIS (Black) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/17604734-coolfire-uv-free-solar-watch-fast-charger-for-all-eco](https://www.desertcart.tn/products/17604734-coolfire-uv-free-solar-watch-fast-charger-for-all-eco) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-03*
