Solar Watch Fast Charger-Watch Solar Charger Metal Base, 9 Hours Timing Off,Fast Heat Dissipation, Solar Power Portable Charger, Suitable for Casio/Citizen/Seiko/Garmin Solar Watch Rounkin (Black)

works exactly as described, would buy again and recommend. I've been an eco-drive watch user since 2000, and while I'm outdoors a lot, the watches tends to get low charge in the winter in the NE, due to lower sunshine times. it would charge fine with fluorescent and incandescent bulbs, but today they are all gone from my home. I use my own DIY charger box, using a swan neck lamp with a bright white 5000K Daylight White 1500 lumen standard bulb that eats 13W that I just put the watch under, with some distance as it does get warm to hot as you get close. the setup works but its clunky. new eco-drive watches will use up a full charge in 6 mo, but drops as it gets old. also depth meter watches will eat the batteries faster when used in diving, as the meter uses a lot of power. Pros far more ergonomic than my DIY setup and works does not get hot but warm. with the setup provided, the watch will < 95F with 72F ambient, and stainless steel watch cases will radiate this heat away too, so you feel and measure it with a IR thermometer the charger is made of metal, not plastic, so it heat sinks out the heat on its own very simple setup and all provided accessories but no USB power source, you need to use your own only one power setting, 9 hours charged timer, confirmed appears well made and durable but only time will tell as usually power LED tend to die off faster with use excellent simple design watch charges to full, I have one ecodrive that has a power meter and confirms this Cons no organizer case

I picked this up as a safe way to charge my solar watches, and it does exactly what I hoped. It provides steady, reliable light without overheating or risking damage to the watch. The included silicone rings are a smart touch. They hold the watch in place and protect the face and bezel from scratches, so I never feel like I am risking my investment. The light output is strong enough to get a solid charge going without having to leave watches sitting in the sun or near a window all day. The timing feature is useful too. Being able to set it and forget it gives peace of mind that I am not overexposing the watch. The metal base feels solid and stays cool thanks to the heat-dissipation design. No cheap, flimsy plastic here. It is compact, easy to store, and looks clean on a desk. If you have solar watches and want a safer, more controlled way to keep them powered, this little unit is worth it. Simple, effective, and watch-friendly.

This is well-made, hooks up and powered by USB-C via USB-A cable. It is amazing how after 9 hours, it shuts off, as advertised. It is blindingly bright, but for how bright it is, it emits very little heat, and the watch stays cooler than if it was on your wrist. I measured the temperature of the back of my watch, and it is 84.7 degrees F, and the charging unit itself is 86.2 degrees F while powered on and charging a watch. I think this charger is close to perfect. The only improvement I could suggest would be a two-watch charger.

Works very well. Charged my Casio watch that was at medium level power for 15 minutes and it was at high power. I like that this charger is metallic based and is doesn’t get hot. I’m happy with it and would buy it again for my son who has a lot more solar watches than I do.

. Thin profile . Metal base . USB-c connector to light, other end usb-a to wall . Bright light . Highly polished surface . Low heat to none, less than body heat, so it won’t overheat the watch . Can quickly charge the watch better than window sill . Comes with two rubber mount, I use small one for my gshock to avoid light leak in the edges It has some dust inside the clear lens and LED, care to use air blower before final assembly of the clear lens to keep the inside clean of particles.

So many choices out there and competing claims with very mixed reviews of so many other similar chargers. I'm convinced this unit is the best for several reasons. Solid "metal" instead of plastic construction. No fear of fire hazard; hasn't overly produced heat charging either my wife's tiny Citzen watch or my large men's Citizen watch. Easy to use one button self timer, turns off unit after about 9 hours and fully charged older watch to run for up to 10 days. Silicone rings for small or large watches. Unit is quality and proving itself reliable. Pleased with purchase.

Works great, at where I currently live I barely get any direct sunlight on my window, too many trees. My solar watches take up to 2 weeks to get to a full charge. This charger fully charge a watch in just a few hours. I can charge all my solar watches one by one and still be well ahead of the 2 weeks it need to fully charge them from the windowsill.

This little gadget works great for charging eco drive watches. The lightstays on for as long as you want, it's super bright for fast charging, and the watch doesn't get too warm. The only downside was that it won't turn on if you use a fast charging phone plug. It works great with a computer USB port or with an older slow charging phone plug.
