MEGASOLAR 60W Solar Charger Solar Panel with Solar Charge Controller Dual QC3.0 USB 5v - 12v and DC 12v 15v 20v Output, Portable Solar Charger Shoulder Bag for Charging Laptop Solar Generator Phone

Bought this to charge a MacBook Pro while out in the field as well as a few different sizes of USB-C battery.The USB-C chipset the manufacturer chose has a huge flaw. The moment it goes past 30.9W of charging (20V at 1.54A on my USB-C meter) the chip resets, dropping all power on the cable, and restarts. This happens even in full, bright summer sun, and happens at the exact same amperage-output point. The end result is if you use this to charge anything that takes >30W USB-C PD, it will continually stop/start/stop/start every 5 to 8 seconds.If you stay under 30W (say, a MacBook 12, or an iPhone with a USB-C-to-Lightning cable) then the chipset works just fine.As far as the rest (why 2 stars instead of 5) the main DC output works fine, and the USB-A output works to spec. The panels themselves and the folding enclosure they're mounted in are built solidly. It folds up nicely, has good protection and carry handles in a folded state, and the corner-grommets are very solid so you can mount it in pretty harsh wind conditions.The only failing is the USB-C PD non-compliance. Unfortunately that's what a lot of people are buying this particular panel for, due to the rarity of a USB-C PD output on a >50w foldable panel. If the manufacturer could put a compliant chipset in it (or somehow firmware upgrade their existing chipset to fix it) then this would be an absolutely excellent panel for field work. But as it stands, I cannot recommend it.

I ordered the 60 watt model. This model has 6 panels with 4 cells each for a total of 24 cells. These have a total surface area of 0.39 m^2. Standard solar GHI for solar panel rating is 1000W/m^2. The seller claims these are 22% efficiency SunPower cells. 0.39 m^2 * 1000 W/m^2 * 0.22 = 85.8 Watts. This panel should produce 85 watts, but it only produces 60. I have several of my own SunPower/Maxeon 22% efficient cells to compare to this panel, and the color is completely different. Authentic cells are a shiny blue color, while these cells are a very dark gunmetal color. Also it is very obvious that these are not Maxeon because of the way they are ribboned together.60W / (0.39m^2 * 1000 W/m^2) = 15.3% efficiency. That's a low-end cell. They look like P-series tiles, but they aren't shingled, so I don't know what they are exactly. Definitely not what I paid for!Also, the barrel connector cable it came with has the barrel connectors poorly heat-shrunk on to the wire and the inner wires were exposed, and the insulation is damaged under the heat-shrink.

I'd like a SolarPanel that can at the very least charge my Pixel 3 phone and ideally as also my XPS13 laptop via USB-C PD. I believe the laptop expects a 45W 15V 3A USB-C PD profile.I tried the Jackery SolarSaga 100W, which has a USB-C port but does not implement the USB PD standard and can thus charge neither device. I also tried the BigBlue 100W Solar Panel which claims to have USB-C PD standard support up to 60W. BigBlue panel was able to charge my Pixel 3 phone but failed to charge the XPS13 laptop.Finally I tried the Megasolar 100W PD Solar Panel. It successfully charges my Pixel 3 phone as well as XPS13 Laptop. It also successfully charged a HP EliteBook 840 G6 as well as a Xiaomi 1st generation Mi Air 13 (2017) Notebook.However, using a USB-C PD meter I notice that the Megasolar 100W outputs roughly 0.5V lower voltage when charging my laptop with 45W compared to a power-bank or a AC wall charger. The laptops still charge though, but it may or may not be safe. Unfortunately the USB-C controller used by this panel generally is not safe when connecting both the USB-C cable and the DC-out cable to the solar panel. I tried this and it worked initially well, but once the solar panel got into a bit of shade, the panel destroyed the USB-C controller on my laptop's mainboard so that I had to send the laptop for repair. Thus I returned this panel and recommend to instead use a simple solar panel without onboard USB-C controller and portable power station with MBTT solar controller, battery and USB-C PD output.

I bought this panel specifically to charge my MacBook while doing a month-long road trip. In my initial test with direct sunlight, it did charge the powered-off laptop for about 5% of battery over several hours. Once that I took it on the trip, it never charged the laptop again.For iPhones, it did work really well for a couple of weeks. By the third week iPhones started signaling 'device not supported', but it kept charging them anyway. By the fourth week, the panel was not charging the iPhones at all.

I had to buy the extra connectors pack for my Dell Inspiron, but it kept my laptop running during a three-day outage. I have a dell power companion. When it needed to be charged, I set my laptop to power saver mode and connected the power companion to the solar panel which seemed to charge in a few hours in full sunlight. I'm probably going to get another power companion so I can keep one connected to the solar panel at all times when the sun is out. Overall, I'm very pleased.

Bought to use on a camping trip, rained so didn’t utilize in the field. BUT have been using in “laboratory” conditions-back porch!! Charging a PowerAdd 32000 mA battery - has taken approximately 6 hours from a dead battery. Cable with panel kit had more than enough length to get battery out of the sun and charging as cool as possible. Light enough to take backpacking, fits nicely in a 70L pack.I chose this unit because it has multiple DC output levels. The PowerAdd charges with a 15-24v input, which is easily covered by the panel output!!

Expensive but worth it IMO. On the beach in LA it can power a Chromebook 15" laptop plus a phone together indefinitely (batteries stay at 100% forever)Feels good quality as well. Definitely recommended.

Provides the power I needed to run certain electronics I need for camping & emergencies. Compact for space requirements and ability to comfortably carry. Also can be stored in faraday bag to protect circuitry from solar flares & EMPs.

Whilst I’ve only had this product for a few days my initial testing showed that the PD interface works, which was my main interest in the product. It seems to take a while to “warm up” but a quick test in slightly cloudy situation and without angling at right angles to the sun ( flat on a table) I measured just under 20V at about 1.3A. Will do more readying but I can confirm the PD interface does work...
