SunJack60W Folding Portable Solar Panel Charger with Kickstands, IP67 Waterproof ETFE and DC/USB-A QC3.0 / USB-C PD30 for Cell Phone, Laptop, Power Station, Backpacking, Camping, Hiking, Emergency

The USB A and C ports really should have been higher output to better use the 60W of production.Those ports maxed out at about 20W. What's the point of a 60W panel that only puts out 20W?Shading is also a problem. The panels are wired in series, so even a partial shadow on one panel cripples production.It really should have been 4x-voltage panels wired in parallel for maximum robustness in a world with tree cover and a moving sun

I live in an area that gets constant power outages and I’ve been looking for a solar panel to use in emergency and disaster situations. Most of the panels I have found either don’t have enough power or are way too big. The sunjack 60W panel is the perfect solution. Folds up nicely and takes up hardly any room. The construction feels solid too. The best part though, it’s power. I tested this panel on my powerbanks and power station. The USB-C port was pumping out close to 38W and the DC port was providing around 55 watts. That’s incredible efficiency. From my experience most panels like to claim they are a certain wattage but get nowhere near their rated power.

For a portable panel, it's pretty large and heavy. But I don't think you can do better at 60watts. It seems well built and good quality (I've been using it about 3 months). I just want to set your expectations right from the beginning. It should fit in any normal sized bag but I have a laptop style backpack that is barely zips up in so just be aware. It's also heavier than you might expect. I also have the 25watt sunjack portable panel which is more what I would call "portable" 5 stars on weight and size.That being said I think it's great to have a decent amount of power able to fold up as small as it does and be as portable as it is. I'm happy with its portability, it's just not its best feature.I didn't like this panel when I first got it. I originally bought it because of the onboard electronics being able to deliver good amps at various voltages and I had hoped to power my macbook with it's USB-C connection. This works horribly. Due to USB-C being able to negotiate the voltage it wants to charge at it will pick a high voltage which gets very low amps and will be very unstable (it will constantly stop and start charging -- I'm not exactly sure what the cause is but I've seen the outcome. I think what happens is the macbook usb-c negotiates 20V but the panel outputs closer to 18.8V under load from what I've seen). The panel worked very bad under these circumstances. I even had trouble charging my USB-C Anker 737 at times. Power-cycling on USB-C. Terrible investment I thought. Then I discovered the best setup with this panel.The best way to use this panel is to get a DC5521 (5.5mm outer, 2.1mm inner plug size) to car cigarette lighter adapter and get a 12V max USB cigarette adapter (adding to the cost, yes, but something that's very useful with these lower voltage panels) and charge your USB-C devices from there. This way the cigarette adapter setup down-regulates to 12V max and your USB-C devices will charge with much more stability (you limit the voltage USB-C can negotiate to 12V instead of 20V). I use a USB adapter which outputs 12v at 2.25A so 25watt charging. Less than the onboard advertised 45watt but it actually works so there's that. You can also easily add a large extension to the setup. I have a 3m DC5521 male to female adapter with the DC5521 cigarette adapter plugged into that. From there I can use another 3m USB-C cable to my laptop and everything works great. In my case this means I can have the solar panel out in the sun and have my electronics fairly far away in the shade or even run the cable into my home and charge my laptop while using it at my desk. Very nice. The DC5521 port is a life saver on this panel.I wish they had perhaps better tested the real world usability of the onboard USB ports. Limiting them to 15V max would have been a better experience across more devices, I think. That being said, this is my daily panel and provides plenty of power to charge up my macbook m1 and all the other USB devices in my life. The DC5521 port makes this panel much more flexible compared to the 25watt model even though the 25watt model is more compatible and stable with all my USB devices out of the box.Thus ends my overly long but hopefully helpful review :)

I purchased this solar panel to semi-replace a larger/older solar panel. The upgrades are - better solar charging, and a dc and one each usb a & c ports. So far, I'm pretty impressed. My older panel does an ok job, but seeing that my new(er) power banks have usb c ports, and this is lighter than the old panel. My only "complaint" would be how wide it is closed up. Kind of hard putting it a smaller pack, But that's no big deal, still a decent buy!

Best in its class and actually works. Fast charging and works well with rapidly charging my power blocks, AA/AAA batteries, and iPhones. Important to have in survival scenarios and bug out situations. It does not overheat and shutdown like many of its competitors. Solid construction too which is important in survival situations.
