Note: these panels do NOT have a built-in battery pack, and that is exactly what I wanted. I wanted the highest amount of panel efficiency per dollar that I could get and I didn't want any of the product weight or surface area being wasted on anything but collecting rays. Combine this with a proven high capacity power bank and you're good to go! That said, I've heard it's generally not recommended to charge your phone directly from the panels as the voltage fluctuations can shorten battery life, and none of my battery packs can charge and discharge at the same time - so keep that in mind.
Took this in my carry-on, used it while hiking around Denver and the nearby Rockies. Security didn't make a peep, which was nice (and surprising, considering how stringent they can be around battery packs and electronics). Super light weight at ~400g, akin to slipping an extra novel in your bag. And boy is it useful!! Strap it to your backpack or throw it on the seat/dash of a car for a sunny hike/drive and you'll be charged up all day. It also is just fun / feels really good to be walking around collecting free electricity from the sun.
WEIGHT: I'm pretty sure this is the highest efficiency/weight ratio panel set you can buy. I was debating between this and the AUKEY 20W, which also has SunPower panels. It's a little cheaper at $60 and has a handy stand for you to angle the panels towards the sun. However - what made my decision was the weight of the Anker 21W (~400g) vs the Aukey which was double the weight at 800g. An extra 400g is non-trivial - akin to carrying a whole extra Nalgene of water around in your backpack. Thought it was worth it to pay the extra $20 to lug around half the weight - if you think the panels are annoying to carry around, you'll never use them.
CHARGING EFFICIENCY: really varies depending on the weather conditions and the angles you have your panels at. Being physically outdoors seems to help alot. If I had one suggestion to Anker it would be to build some kind of adjustable stand into the panels so you can prop them up at an optimal angle to the sun (perpendicular to the rays). I haven't done any rigorous testing but I noticed that I could fill about half of my 6000mAH pack in 1-2 hours in the full midday sun in Denver (the altitude probably helps too), whereas I can leave the panels out the whole day in indirect sun indoors and barely get 1/4 of my bank charged. In any case, they definitely collect enough electricity to be useful - this isn't just a toy.
HARDINESS: accidentally left these out on the balcony, on a day that started out as a sunny morning and turned into pouring rain. The panels must have been soaked for 5-6 hours. Was terrified that I had ruined them. Came home to a fully-charged 6000mAH bank, and the panels still worked just fine. Build quality seems very robust.
One of the coolest and most useful things I've bought off Amazon. Great stuff from Anker!
I've used several solar panels in the past, and though this is the biggest of them all, its the least klunky and easiest to pack and use. Solar panels typically last me a year, sometimes two. I abuse my items hard in the back woods, so price, weight and durability mean a lot to me. This meets and exceeds my standards so far!
Fast charging in good light, being dumped in a lake proof, survived a few drags and drops. I like the 2 ports so I can charge my power bank and device simultaneously. This thing is so damn simple to use. Point, plug and enjoy my coffee. I really like this and will be buying another to gift to my friends at christmas time for next year!
Pro's: grommets make hanging and pointing in the direction of direct sunlight easy. Large panels for big charging power. Durable. Very Lightweight for the size. Pouch holds my cables well. Folds well in any direction for easy placement.
Con's: one velcro closure on large pouch makes the cables fall out on occasion. Makes me want to bring more chargeable items. Will buy another.
I was able to get 1/2 amp (2.5 watts) of charging current under the following far less than ideal conditions:
Panel was hung vertically against a south facing double paned dusty window at noon. The sun was at 23 degrees above the horizon, and there was a very light haze in the sky. With an iPhone SE2020 plugged in, it took 30 minutes to go from 83% to 96% charge. Given the far less than ideal conditions, I am very pleased with the performance.
The storage panel on the end with the usb ports is excellent, I can hide my cellphone inside the panel while it charges. It rolls up small and beautifully when not in use and is a real space saver compared to some solar panels.
Having two usb ports is one of the best features of this solar panel and make it so much more convenient. It charges two phones on a clear day, albeit more slowly than standard power sources. It will even charge my phone a bit on a cloudy day.
However, the 28W BigBlue is less expensive, faster, and will do even better on a cloudy day. I was given it as a gift because I was so impressed and wanted another Anker. The gift giver decided to shake things up and gave me the BigBlue. I still take both camping and wouldn't hesitate to say the Anker solar panel is very good, especially on a very sunny day. If it was less expensive than the BigBlue then it would be a better deal.

Update-
I just finished charging my Anker 26800 power core with the solar panel. It was a clear sunny day. I angled my solar panel torward the sun and started charging my power core at 8:30 in the morning. It had two out of four lights lite when I plugged it into the solar panel and the second light started flashing on my power core letting me it was charging. It took 6 1/2 hours for the power core to be fully charged. Over that time I adjusted the solar panel’s angle twice. As far as I can tell the power core charged anywhere from 50% to 75% in that time frame. That is still an average charge of about 25% every two hours. Not a big change from the two cloudy days before. This is a huge power core and I have not drained it in any less than 3 days. I charge my spotlight, headlamp and, my iPhone 5s from this power core. I have also run my two camp lights that are 100 lumens each overnight for about ten hours and they did not even use 25% of the charge from my power core. See picture of the things I have charged. I am very happy with how well this solar panel preformed. It does not seem to have any trouble charging my Anker 26800. I do not see myself running out of juice to power my toys on multi day hiking and camping trips. In order for that to happen, I would have to have no sun for 3 or 4 days. But, this solar panel seems to have the ability for a slight trickle charge on completely overcast days. I will try that next to see how well it works. I may have to limit my use of some things but I don’t see myself running out of power completely. This solar panel has preformed beyond my expectations and I am very happy with it. If I ever need more then one, this is the one I’m going to buy.

Es muy compacto y fácil de llevar, tiene muy buena eficiencia en la producción energética.
Tal vez la única contra, es que se debe tener cuidado de no llevarlo en algun lugar donde pueda ser doblado porque podría romper las celdas fotovoltaicas. Pero si se lo trata como a un iPad o incluso más rudo, lo debe de soportar.
I wasn't expecting it to keep up with our usage, but it did a fantastic job! Placing it on the top of our tent through the midday sun, or angled towards the sun in the morning/afternoon making sure to always be topping up either of the two backup batteries.
Our phone usage was medium/heavy with google maps, photo uploads and Pokemon Go. Both phones would receive a top up charge twice a day from the backup batteries, with those charged throughout the day from the panel.
I did not test charging both batteries at the same time, despite 2 x USB. Even with Australian summer sun we found that the charge rate on even 1 port didn't sustain 2.4A which is a shame, but not a surprise for such a small panel. We expected this and so weren't dissapointed, but please keep this in mind if you are purchasing expecting to sustain 2 x 2.4A ports for your charging needs.
Take care when charging in full sun, particularly Lithium batteries as they can get hot, try to keep them shaded away from the panel with a short cable (the shorter the better to avoid voltage drop from the panel).
Also, invest in a quality cable, the one that came supplied unfortunately had to be replaced after a couple of weeks usage (also expected and so not dissapointed by this)
Overall, very pleased with this product and looking forward to using it for future trips off the grid.
Physically, it is divided into four foldable sections: three section have solar panels (there are metal grommets in the far corners of the solar panel-containing sections), while the fourth section has a small velcro-closed pocket containing the charger electronics and two USB ports in a small plastic housing. The strip of velcro used to close this pocket is small, and will not retain a phone well if the PowerPort Solar is moving (e.g. strapped to a backpack). Either add more velcro yourself, or use a cable to connect to your device inside the backpack. Keeping your phone or other device out of the sun (or the enclosed pocket) is probably a very good idea, as the panel and the pocket get quite warm in the sun and your device may overheat and turn off -- keep the PowerPort Solar in the sun run a cable to your device in the shade (Anker PowerLine cables work very well, particularly at high charging currents.).
Build quality of the PowerPort Solar is excellent, with good stitching, high quality grommets, SunPower solar cells for greater efficiency, etc. My only suggestion would be to use a full-length zipper instead of the short piece of velcro to secure the pocket.
Like all solar panels, it is extremely sensitive to its positioning relative to the sun: on a bright, clear sunny summer afternoon at ~46 degrees north latitude it provided 2A at 5.05V from one port into a 2.5 ohm dummy load when angled to be perpendicular to incoming light. A modest change in angle (say 20-43 degrees) results in voltage and current dropping to 4.8V and 800mA, respectively, with the same load. Similarly, small changes to incoming light (e.g. a light haze in the sky, or a cloud passing in front of the sun) will notably reduce the amount of power it can provide.
I've found that it will charge my Motorola MotoG3 phone (the phone has an internally-limited maximum charging current of 1A) at the phone's maximum charging rate in moderate conditions (e.g. partly to mostly cloudy) with no problems, but your mileage may vary. Many devices have "smart" charge controllers that will automatically cut back on charging current if the supply voltage drops (e.g. a cloud briefly passes in front of the sun), then attempt to increase the current again if the supply voltage increases. Such devices are well-suited for this panel and will charge well.
Some smartphones or tablets will light up their screen for a few seconds when they are first connected to a charger. In marginal conditions, like late afternoon, the PowerPort Solar's output is insufficient to charge the phone continuously and it will send short pulses of power. While not harmful to either the PowerPort Solar or the phone, the phone will interpret these pulses as it being repeatedly connected and disconnected from a charger. This causes the screen to light up, turn off, light up, turn off, etc. and generally waste more power than the trickle you'll get from the PowerPort Solar. In short, use the PowerPort Solar with confidence when the sun is bright and directly falling on the panels, but stop using it when conditions get marginal.
Some devices, like the Anker PowerCore 20100 power bank, will reduce the charging current if the supply voltage drops and will remain at that lower current level until they're manually disconnected and reconnected. This makes it very impractical to use such products with the panel, as a single cloud can dramatically increase the time needed to charge the device. If you want to use this panel with a power bank (which is generally a good idea, as you could charge the power bank during the day with the panel strapped to a backpack or something, then use it to charge your devices at night), make sure the power bank will automatically recover from brief voltage drops and will attempt to increase the charging current again. The PowerCore 20100 doesn't recover from such situations without being disconnected, though I've raised the issue with Anker and they're looking into improving things for future models. Since power banks don't have screens like phones or tablets, they avoid the on/off screen issue described above, and are likely a better choice to charge in marginal conditions, assuming they recover from voltage dips.
The two photos I've included are of the PowerPort Solar resting against my backpack outside on a sunny day, and the display of a generic PowerJive USB volt/ammeter : you can see that the panels are providing exactly 5.00V at that moment (the voltage typically varied between 4.8 and 5.1V) and 1.97A of current and that the panels had charged my PowerCore 20100 with 737mAh so far. Both photos were taken during my lunch break.
In short: if you're willing to accept the shortcomings common to all solar panels (e.g. sensitive to angle relative to the sun, sensitive to clouds, haze, and marginal conditions, etc.), the PowerPort Solar is an excellent choice and I highly recommend it.
