I had to write a review on this solar/battery system with the LED lights that come with it. This is a fantastic system that can do so much, and I am very happy I found it a few years ago and bought it. I can't remember what I paid for it then, but it has been worth every penny. It was packaged well, and came to me undamaged. I think I have used it for 3 camping seasons so far, and it can light up my camps like you have on grid lighting.There are 2 different wattages of bulbs, that burn very little power (2.5 and 3 watt I believe), I can't remember now because I have bought other types that also plug into the USB ports and have inline switches. The cords are around 16 feet long with inline switches near the battery pack end where they plug in. I bought shorter ones for closer in, and even bought some USB extension cords to reach farther away. Since there are 5 USB ports on the battery pack, you have 5 options (or more if you add multi port USB extensions). I have to say that I usually don't use all of the 5 lights at once just to conserve energy, but I have had them all on at the same time for several minutes without any issues. Even the smallest wattage lights, one at a time, can light up the whole camp brighter than most lanterns, and I only use a lantern now to set up if I arrive after dark.Another cool thing about the lights are that if you have any kind of portable power pack/supply with a USB port, the lights will also work in them for hours. I have found that the 2.5 watt bulbs will work in a 2-18650 lithium cell pack for a few hours, so that makes them a more portable light source for tents, RV's, hiking, etc. And the cool thing is that you can plug the portable 18650 packs, or anything that can be charged by the 30 watt solar panels, into the power pack to recharge them the next day in the sun. I have several items I recharge while camping, a lithium tent light, cell phones (Usually 3 at a time), my head lamp, portable Bluetooth speakers, battery packs, etc., etc., and they all get charged full by night fall.I did make one modification to the battery pack though that I think is a good idea...I was concerned that the little LED light stays on on the battery pack during storage, so I opened the case, and installed a master battery cut off switch so the power pack wouldn't trickle discharge while not in use. This modification works great to insure the charge is kept maximized over long non use periods. I soldered and shrink tubed the connections to eliminate possible shorts for safety, but this would be a nice factory modification to have a master off switch. I would like to see that, and possibly an optional carrying case like a lightweight suitcase for travel and storage.The panels (that are closely and permanently wire connected side by side) work well, but are bulky when bolted to the frame that came with them. At first I just laid them out on top of my truck, and when breaking camp, I simply folded them together and stored them in a felt bag. But once I took the time to bolt them to the rack, it became too much of a hassle to take them apart, and I was afraid I would loose the tiny nuts, washers, and bolts. I think a good remedy for this system would be a fold up flexible solar panel that could also be more versatile for portability on hikes, boating, and car camping, etc..So about 3 years of use so far and still working great! I love it, and am very happy I chose this system. I would like to see some greater Lithium Ion battery pack and charging sized packaged options from this company, if there is any? There are several companies now coming out with larger battery pack storage options with multiple types of power ports, so it would be nice to have a bigger pack with a pure sine wave inverter built in with 110v and 12v ports. I have numerous ideas if anyone is interested? I hope this helps with anyone looking to go green as much as possible?Ed in Kent, Wa. USA
