Portable Solar Panels 40W, Foldable Solar Panel Charger for Power Station

work great

While I cannot speak to the longevity of this product (40w version), I can speak to the size, weight, and charging ability. I just spent a week in the Boundary Waters with scouts and I must travel with a CPAP. We canoed about 9 miles in a day to reach our campsite with about 9 portages. I had this panel strapped neatly under the canoe seat with some dealy-bobs. I run my CPAP off a 40k/mAh battery (generic) that has a 15v/2amp charge port. Most panels available only have USB (5v) outputs, whereas this panel has USB 5V as well as DC 15V output. I compared a 'well-known' portable panel with it's proprietary connections, that weighed more, and cost roughly $200 more than this. After purchasing this and testing it for a couple weeks before my trip, I put it to the test. On a bright sunny day, my battery goes from 0 to 100% in about 5 hours which actually seems faster than using the AC adapter - I have yet to do a timed test. Weight for a 40w panel was great, especially with the additional weight of the battery and CPAP - I needed something that could charge as much as I needed but still be portable. Size, while I could have fit the panel in my 85L backpack, I had too much other gear for a week-long trip and decided strapping it under the seat as the best mode of transportation. Bottom-line, after charging my battery and the rest of the leaders' and scouts' electronic devices on the trip for a week, this is well worth the money! I also appreciated the DC plug adapters which I needed for charging the battery and CPAP (to the battery). I would highly recommend upgrading the provided DC cable as 22 gauge just wasn't robust enough to handle the power effectively. I went with an 18 gauge charge cable.

Got this foldable 60W panel on a super good deal (<$100), perfect for a rechargeable battery pack inverter for emergencies. Performs great with high efficiency cells, down to low light/clouds as specced. Multiple adapters included, charge-ready 5V circuits available without battery intermediary. (You can charge your phone right off this panel, etc.) The utility issue I realized after I got this is, this is a 'fair weather' panel ... To make it portable, it's wrapped in some sturdy (nylon?) cloth, which let's it fold into thirds so you can carry it like an oversized briefcase. This, plus the minimally shielded electronics (letting you hook your phone and everything else directly to the panel), means you can't leave it out in the rain - No! It has clever angled props to face it at a good angle to the sun, but a good wind will knock it down or slide it off the table -oops. (Or the curious dog can swipe it.) So this means you either have to babysit it, or put it away when you're not there/wind/rain/dogs/things you can't control. A trade-off I didn't see at first. But since it works best in the sun, this is a sunny day item! Not a set it and forget it item, nope. When it's working, it's awesome for the price!!

I bought this just for fun as I don't camp and power is cheap enough in Santa Clara that I don't need this. However, I bought a 298 Kwh power station and it had an input port that supports a 60W solar charger and this was relatively inexpensive so I picked it up. After 2 days of about 4 hours/day in the sun, it does appear to generate 60W of power through the DC cable. The USB ports get 30W (My power bank has input power meter). I can't measure the DC power, but based on time, 60W seems to match how much charge I'm getting. I did measure the voltage and out of the sun, I saw 5V and in the sun upto 21V. So I'm pretty happy with it and so far recommend it if that's what you need. Edited the title and now adding more. I have a 2700 mAh power bank that has input/output upto 100 watts. I've confirmed it can take 100 watts. I recently connected this power bank to the solar panel in full daylight using the C port. Well, this port appears PD (power delivery) ready and actually pumps out 40 watts!!! That is more than the specification of 30 watts. When charging my Pixel phone, I'm getting 15 watts which is just all the phone is asking for at 70%. Don't know what it might want at 10% charge. So I'm more than happy with the solar panel. My power bank went from 18% to 99% charge in 2 1/2 hours. That's 81 wH of charge. Incredible.

Great for camping or just road trips; I put it on my dash.

Not sure if it was the sun but this solar panel was only outputting 40-43W. Brought it to charge my jackery for our camping and I put it up under the beaming sun and like I said, the output was only what I mentione above. However, very easy to store, I like how it folds with clips to secure it. As well as having a little pouch to put all the wirings and extensions. Overall, this solar panel is very well made, I'm just a little disappointed that it does not match the output that it's advertised with.

I bought this for a camping trip to the outer banks of NC. We go every year and there is no power on the island. I got this so we could keep phones, lights and fans powered up. It was great. I would take my devices each day and plug it up of a day with the panels in the sun and within a 3-4 hours everything was charged up. I think this is going to be a great purchase for camping as well as when we have bad storms, and hurricanes. It is light weight so easy to handle and set up. It gives you everything you need to connect all your devices.
