Connectors are the worst. Solar Cable Connector tools will NOT work with these cables.

Added this fan when the when the smaller (4") red fan was not enough. Install was easy, the nylon wall anchors made usable nuts for the provided screws when mounted to the greenhouse panels. I added some supports to the solar panel bracket so I could mount it on the greenhouse apex and have east/west tilt adjustability. The louvers are nice, they give you a quick visual that the fan is running, There is also a grill on the other side. The fan moves a decent amount of air, even in bright overcast skies. It is relatively quiet, you hear the air motion.

I’m impressed with this 1200W wind turbine! It’s easy to install and perfect for my off-grid setup. The MPPT controller ensures efficient power generation. It's eco-friendly, durable, and provides reliable energy for my home. Highly recommend!

The item arrived earlier than I expected and was packed securely. I purchased it along with the solar panel. The latest model includes app control. Just download the app, follow the instructions to connect to the device, and start using it right away. Also, I heard that the battery has been improved and the number of charge and discharge cycles as well as the battery power are now significantly increased. The warranty is 5 years and it is great to have help available at any time if something goes wrong. I followed the setup instructions, fully charged the device, and then discharged it.

The Callsun 50W Flexible Solar Panel is a game-changer for anyone needing portable, high-efficiency solar power on the go. Designed with mono crystalline PERC cells and a 23% efficiency rating, this panel delivers impressive energy output despite its compact size. The flexible, ultra-thin design makes it perfect for curved surfaces on RVs, boats, or camper vans, while the IP68 waterproof rating and ETFE material ensure durability against harsh weather, UV rays, and wear. I tested it with my Bluetti AC2A portable power station, and the pairing worked flawlessly the panel efficiently charged the unit even under partly cloudy conditions, proving its reliability for off-grid adventures. One of the standout features of this solar panel is its lightweight yet rugged construction. Weighing just under 4 lbs, it's easy to transport and install, whether mounted with adhesive or secured via the pre-drilled holes. The ETFE coating not only enhances light absorption but also resists scratches and yellowing over time, ensuring long-term performance. The included 10ft cables with MC4 connectors provided ample reach for my setup, and the panel's low-light performance was surprisingly good, maintaining a steady charge in suboptimal conditions. While 50W won't power an entire RV alone, it's ideal for maintaining batteries, running small appliances, or supplementing a larger solar array. Overall, the 50W flexible solar panel is a fantastic investment for campers, boaters, or homeowners seeking a compact, high-efficiency solar solution. Its compatibility with portable power stations makes it versatile for emergency backup or outdoor recreation. The balance of portability, durability, and efficiency sets it apart from rigid panels, and the sleek black design blends discreetly on any surface. If you need reliable solar power without the bulk, this panel delivers exceptional value just pair it with a quality charge controller for optimal performance.

Light weight, portable, charges even with cloud cover. Good enough that it charges my portable battery pack fully over 5-6 hours which I then use to charge my phone and watch. You can plug multiple things into it at once. Works really well.
