## Description

desertcart.com: CoolFire (The Original) - USB-C UV Free Solar Watch Fast Charger for All Eco Solar Watches. Safe 24/7 Charging (No 8H Timer Needed). Reloj Hombre Portable Charger. BK : Cell Phones & Accessories

Review: This little light works incredibly well. - This little light works really well on most solar powered watches and it has absolutely changed the way I charge my watch. It is not very big so it doesn’t take much space and has a few rings to make it fit different watches but it works unbelievable. I have a watch that is very special to me and it was acquired back in 2011. The watch was always on half charge even if left in the Florida sun for the entire day. This charger has fully charged it in around 6 hours and it doesn’t heat up the watch and with the watch over the light there is not a lot of light blasting out in the room while you sleep. Appearance is not bad and the compatibility should work well with any solar watch. A must for anyone with this type of watch.
Review: Fast, simple, cheap Universal charger for all of your solar watch needs. - As the title says. This will work with any solar/Eco-Drive/Garmin wrist or smart solar device. Powerful 40,000 Lumen output charges my Citizen fully in just 10 hours. (high setting powered via USB) In the box you get a booklet of instructions, 2 silicone rings to gap the watch face just far enough away to prevent substantial heat buildup. And one USB A to Mini USB cord for power supply. It has an internal AA battery compartment for low power charging on the go. The mode selector switch only work on "High" with USB cable connected to a power source. It will NOT run low power charging unless there is a set of AA's in the compartment - and honestly, it's output is weak. Much weaker. By the time you run down the AA's, you *might* have half charged an Eco-Drive. In a travel, or weather emergency, I guess it is better than nothing at all. The two different silicone rings mate to the faces of various sized watches, so try them to get the best light leak free interface. It does not come with a square "Casio" Tough Solar specific ring, but you can still balance one on top with the round rings just fine. Note: The charger ships with a scratch resistant film applied to the face of the lens. Remove it to gain full, unobstructed light and overall performance. I only used it with USB power, and the "High" output setting. It works very well for my purposes. To revive "dead", inoperable devices, follow instructions from device manufacturer to stop your movement or "shut down" your smart watch and then leave it up on this charger for at least 2, maybe 3 days. It can pull them back from the dead, provided that your solar cell is in good condition. No amount of charging on this device or days left in direct sunlight could pull a completely failed device back to life. I have unscientifically measured the light output on the high setting using an Android phone with a light sensor app that used the proximity sensor on the phone. Point blank, resting on the rubber ring I measured (A slightly jumpy) 39,500 ~ 42,000 lumens. The lightweight and small construction makes packing it simple. Use is as simple as finding a ring that fits. Prop the watch up on it and turning it on. I find an overnight run while I sleep to more than adequately keep my solar watches running at their best. No fear of overcharging or overheating my watches - the puck runs cool. My watches have built in overcharge protection. You just have to be patient depending how discharged or dead your watch is. Charging on high is roughly equivalent of 40% of full sunlight in high noon, so calculate roughly how long you need to set your device on it. It was a no-brainer purchase as I am a night owl. I rarely see full, or daily sunlight, nor have enough ambient light to at least maintain the hybrid battery charge in the long term. This simple to use gizmo takes care of all that and any charge anxieties you may heave.

### ⭐⭐⭐⭐⭐ 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. 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.
