MARBERO Solar Panel 60W

Well made portable panel that folds down to a very portable size. Testing under ideal conditions I got around 80w/100w from DC, and 45w/45w out of USB-C PD (15v 3a). A major reason I picked this panel was the mix of portability and the fact that it had decent native USB output. Legs are a little finicky but once set up the panel stays put. This panel is NOT without its flaws 1) When folded there is no snaps, nor is there a handle, nor does it come with a carry case. I would have liked a handle or something to make carrying it a little nicer, but it's not a huge issue 2) that 80w test result was in conditions that my good 100w panel gets its full 100w. If it wasn't for the fact that this panel was quite competitively priced I would have docked a star for this.

Works just like it is supposed to charge, I use this to charge my portable battery when we are out camping with no electricity. Works great, I place it on the roof of the truck where it will get the most sun light.

The solar power fan system is great, but it does not generate the amount of air flow I wanted for my Greenhouse. I think it would be nice for a small dog house or small chicken coop. It was simple to assemble and works fine.

UPDATE: Seller sent me a new one. Very nice. It was easy to set up, although it took me a while to figure out what the brackets were for. They are to connect the fans together before you put all the front plate screws in, so I did have to remove several screws and replace them after connecting the fans together. You dont need this bracket if you are using the fans separately. These fans are VERY small, yet push a lot of air. My inside run is probably too big for these, but they are perfect for inside the actual coop, where it gets really hot. The fans only works if the solar panel gets direct sunlight as there is no battery, so make sure your placement of the solar panel gets sun for most of the hottest portion of the day for optimal function. The cable length is good. MY ISSUE is only that one of the fans works. See the video. If I manipulated the cord it would start spinning, only to stop again. I could not find the "sweet spot" to keep it working. I will contact the seller and see if they can send me one fan. I have it all installed and would rather not take it down, and one fan is better than none in 100-degree heat. I will post an update on customer support. EDIT/UPDATE The seller contacted me and is more than willing to send a new fan at no cost. Very nice.

Purchased the 200w panel to pair with my Aferiy P210 battery. First impressions out of the box are that this is a pretty nice product- very well made and looks and feels high quality. Without any real care to how I set the panel up, just pointing it in the general direction of the sun, it is charging at 145w at about 4:30 in the evening, but that is in a really hot Texas sun. I'm sure it will do a bit more with some more positioning and the sun higher in the sky, but I'm satisfied with it so far. Will definitely be buying more of this brand.

Charged my 88wh Marbero solar generator to 100% with less than a full day's worth of clear sunlight - took from about 10:30 AM to 4:20 PM. Comes with every adapter plug under the sun and mounting clips for your backpack. Easy to deploy, feels decently rugged, no complaints. Using the DC power plug under ideal conditions., this unit will get you days worth of phone juice before sundown. Haven't had the opportunity to test it on a cloudy day, but I doubt you'd have to do too much power rationing. USB-A charging under ideal conditions should fill a 10,000mAH battery to roughly full in the same timeframe or slightly less. Highly recommended as a bit of disaster insurance or as a camping companion.

First of all, solar panels are rated under lab conditions that are VERY unlikely to be duplicated in the real world. I tested the panel on a 85 or so degree F Texas day with solar intensity measured around 1000 W/Meter squared. This is as about as close to lab conditions as you can except cell temperature is much warmer than the lab spec of 25 degree C (~77 F). Here is what I got: USB A port - no load voltage 5.05 VDC with 0.76 Amp load voltage dropped to 4.12 VDC (3.13 Watts) and with 1.16 Amp load, voltage went down to 3.85 VDC. These were with a commercial USB resistive load bank. USB C port - no load voltage 5.15 VDC once handshaking to allow higher voltage we got 8.8 VDC at 1.52 Amps and 4.90 VDC @ 1.68 Amps My Samsung phone accepted this without a slow charging warning. The DC power port showed Open circuit Voltage 19.3 VDC, and a short circuit current of 1.83 Amps, then under a load of an automobile headlight we got 1.5 Amps at 16.3 VDC - So real world conditions showed a little over 24 Watts, really not too bad on that DC power port, should be fine for charging nominal 12 Volt batteries, but the USB A port voltage dropped pretty low under load. I'd recommend using the USB C port for charging phone or power bank if at all possible. Three total panels, with 2 fold out fairly stiff panels, main panel has bumpout with the USB A and USB C ports on one end and a co-axial DC power port on the other, nice blue LED shows charging, it will light even under fairly bright interior room lights, so that doesn't mean you are getting full power when it is on. Both ports have tight rubberish plugs to keep moisture (and often fingernails!) out.

It folds up to a reasonable size, and the connections give you quick and easy options to tie it into your system. I regularly got between 70 and 90 watts, so the rating is accurate. It does not have a battery. I primarily set it up in my windshield, and it's a very good size for that purpose. It does get hot to the touch, but it's a dark product in direct sunlight so that's expected. It doesn't get hot enough to damage anything. I have had it crack ominously a few times while setting it up and taking it down so I have concerns about the rigidity and lifespan, but for now it does what I need it to.
