Review: works as described, solar watch charger that doesn't get the watch hot - 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
Review: Great little charger for solar watches, safe and gentle on the finish - 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.

### ⭐⭐⭐⭐⭐ Outstanding Solar Watch Charger
*by K***5 on December 13, 2025*

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.
