It worked for the intended purpose, a good price too.

I relied on this product to provide minimum power for my phone and laptop in a very remote location with abundant sun. Did not work at all. It seems like it was missing a part or an additional system to work. Major upset.

It works pretty well for what it needs to work for

This is my initial review of the sorulykin 30w solar panel.Build quality:The panel itself seems very sturdy and seems rugged enough. There are some quality control issues to be aware of (see pics). The charge controller alignment with the rest of the panel is off. Some parts of the panel are a little wrinkled. The dc 5521 tips are short, compared to others, however they still work. These issues don’t impact the panel function.Size:This panel is very compact. Like one other person mentioned is similar in size to a 10 in tablet. This is very convenient as I plan on keeping this in a laptop backpack, so I can work outside. I have a briefcase sized 60w solar panel, which works well, but having a smaller panel option is nice.Performance:The manufacturer claims that this panel supports QC 3.0, up to 12v. Indeed, on a cloudy day I did confirm this. The max load for standard USB is 2.4 Amps at 5 volts. I got 2.5 Amp before the panel cut off, which confirmed the claims.Also, I measured the 18v DC output voltage without a load and got 21 to 22 volts on a cloudy day. This is typical for an 18v output with no load. Note: the 4 panels seem to be wired in series, which means that if one of them gets covered up, the voltage will drop quickly (~4 volts with one panel covered up). I believe other small panels with 18v output are also wired in series, so no surprise here.I don’t have any way to measure the wattage from the dc output, yet. But using my voltaic systems V88 battery bank as a load, the Sorulykin 30w panel was able to charge it fast enough (all 5 bars activated). I was able to charge this battery bank, while it was powering my Lenovo laptop. I can work outside with this setup, without bringing my much larger 60w panel.Warranty:No obvious warranty provided. Customer support is claimed by the “warranty card” but the website doesn’t exist and no one has responded to my Amazon question, yet (minus one star).Initial conclusion:Performance seems to align with claims. The 18v dc output works with my solar battery bank, which is why I got this panel. It’s small enough to bring in a backpack, which via my solar battery bank can be used to power my laptop.Update:- A quick test with a usb tester spliced to DC5521 cable measured 18 to 19 watts on a partially cloudy day (using a usb load HD35).-I also measured about 14 watts going into my V88.-I’m curious to measure power on a clear sunny day.Update #2-1.5 months later, on a clear March day in California, I got a consistent 20 watts in the afternoon.

This portable solar panel is perfect for my off-grid jungle house in Mexico. I like that the plug-ins have their own compartment so the cables don't get too hot when lying in the sun. I have another portable solar panel which doesn't have it so I always have to hide the cables behind it. Also it charges very fast my Power Station and rechargeable USB headlamp. Great buy for this price!

Exceeded my expectations! I figured it would at least charge a phone but, this thing is POWERFUL! I’m charging big 20,000 mha battery packs in a few hours from dead! Has multiple outlets and options so that you can charge multiple devices with the cords provided!! Very impressed and not a gimmick or ripoff!👍🏻🇺🇸

The solar panel is awesome! Well built and I'm sure will last for YEARS. Bonus, it came with multiple adaptors for your charging needs.

This product just doesn't work. My phone lost battery while I was using this to charge under bright sunlight.
