Kohree 100W Portable Solar Panel Waterproof, Foldable Monocrystalline Solar Panel Power Charger System Kit for RV Camping Outdoor Boat Emergency Backup Power Station, with USB/PD/DC Outputs 18V

I had read the reviews beforehand which pointed out that other people were not getting a full 100W from this panel, but the pricing was good, so I knew what to expect.This is why a lot of people by a panel with a higher output power than their battery can actualy accept.Eg, purchasing a 140W or higher panel when their battery pack limits the input to 100WHowever, I was also aware that this panel and my Oupes 600W Battery Pack were perfectly matched due to their additional in/out connectors....I live in So California and we get a lot of Sun.On a 90F day with cloudless skies, I get about 74W from the XTC60 output connector on the panel, as can be seen in the attached photo.The 5mm connector gets a similar output when I measure using the power meter and battery pack.Ie, I get 74W from the XTC or the 5mm. Not both togeter at the same time.If I take the main output from the XTC60 and ALSO conneect the USBC connector from the panel into my OUPES 600W battery pack, I get an additional 15W, for a total of 90W from the panel using both simultaneously.If my Battery Pack did not have the additional USBC in/out capability, I could see why other people would complain about the low output power from the panel.I mention the Oupes 600W battery pack because I have noted that some of the higher capacity ones do not allow power Input on the USBC, so ensure that your battery pack does allow USBC input if you want to use the additional power connector from the solar panel. Note that the input power is shown on the top of the battery displays in the attached photos, not the center number (charge %).

This is a great portable solar panel. I am coming from a way cheaper 0ff-brand and my experience with this one is already way ahead. The little handle is well built and feels strong. Made of metal or aluminum but feels like it will last. Has an xt60 standard output which is perfect if you are using a portable battery (EF Delta) and plug directly into the unit, bypassing Klunky mc4 connectors and adaptors for a much more efficient charge rate. I've consistently hit 88 watts (early fall days) And reached up to 92 watts out of the box, that is pretty good! That's a novel idea, actually have your advertised wattage close to or resembling real world outputs! Im sick of these companies claiming 100 watts, 200 watts and after real life usage and beatings you're lucky to get 50% capacity out of said panel.Probably the best and most usable feature on this panel is the provided USB and USB-C output connections. I didn't really think I'd need or use it, but I find myself charging my devices and batteries and phone all the time off this. You can bypass a solar generator and charge directly from the panel. This is awesome because I now have the ability to not even lug my solar genny if all I need is to charge is some laptops and phones during the day. Be aware though, the USB's are regulated, the usb is 18w and the usb-c is 45w and you can use both at the same time so you can't pull the full 90w from the usb ports. Only the xt60 will provide the full output (once again if you have an xt60 input as while you charge devices off the panel, any leftover watts will go to charge the solar genny, perfect!)The kickstand is kind of hokey but works surprisingly well. I feel those will be the first to fail but if you're just placing it on grass or concrete on your driveway, it would work just fine.Happy Solar Harvesting :)

This is a good solar panel. I get about 80W/h on most days. However, that is highly variable. I have to pay close attention to it and adjust the angle every hour, make sure no shade moved over it, clean dust from it, ect. Often I just set it out and forget it and it works for my needs. I like the attatched cord that come with it, I spliced a longer one to it so i have more distance. I also like the ports on the side for my other accessories. I like the magnatizes flaps so it stays closed and overall seems to be a sturdy construction. However, I do not like the cloth wrapping. Gets dirty and is very hard to clean.

I have a Jackery 880 and a Jackery 100W panel now. I wanted to get a 2nd panel and was curious if these other value brands were worth it.Oddly, the Kohree doesn't let you plug into non-Kohree charging stations via it's main plug. It has a XT60 plug that is hard wired into the panel. This plug only works with Kohree charging station or others that my use a XT60 plug. Instead, it has another output that uses a DC5521 plug. They do include this and also adapters. I thought it odd they did this rather just provide an adapter to fit to the main XT60 plug. I do wonder if the reduced output of the panel may have been affected by this. I wonder what the output would be if I got a XT60 to 8mm connector and ran it straight from the main plug. This comes to my reason for returning it. I like in the mountains in California, so we have good, strong, intense sun. I plugged tested my Jackery 100W vs the Kohree 100W. When the sun was 1/4 up in the sky, I only got 60W from the Kohree 100W. My Jackery was at 80W. When the sun got up to 1/3 up in the sky. My Kohree gave me 60W while the Jackery was up to 95 to 100W (yes, I was surprise I was actually getting 100W). I tried changing angles but 60W was the best I could get from the Kohree.I got the Jackery 100W for $250 on sale. The Kohree 100W for $140 on sale. If I were looking strictly at $/W, the Kohree is $2.33 dollar/watt while the Jackery is $2.5 dollar/watt. But I converted a bus to an RV and designed and installed a full solar system. I used it full power my bus for a few years. One thing I learned was having the most actual charging watts/hour is key when I was limited on sun. So having a panel that is much more efficient is worth it to me. For those where lower efficiency is not as needed, the Kohree maybe a good value. Note: went I put both of these panels on my Jackery Y connector. The most I could get was 120W. That was only 20W more than just using the Jackery 100W. I will be borrowing my buddies Jackery 100W to see what I can get with 2 Jackery's together. Have fun out there and GO SOLAR.
