FlexSolar 40W Foldable Solar Panel Charger with USB-C and USB-A Outputs for Phones, Power Banks, Tablets – Waterproof for Camping, Hiking, Backpacking

DC out works
The DC out works, giving direct access to the panel itself, which seems to perform fine (like I’d expect for a 40W panel – I got 20W in non-ideal conditions). I didn’t try the direct USB charging part.The holes make it plausible to find a way to put it up so it catches more sun at a nice angle. This one is more about hanging it from a tree or on an incline facing the sun or similar – it doesn’t come with any HW to prop it up, but sticks and rocks are fine for that.When folded and in its box, it survived being in checked luggage, and it seemed fairly sturdy that way.

Versatile
Avid kayak camper. Got this solar panel to charge a power station but found that the station prefers a slow charge which kinda blows the solar idea. i got the power station to charge my phone and other electronics i use while camping. Ironically this solar panel charges my phone and those other electronics quicker than the power station including my bose flex Bluetooth speaker. It has 3 outputs, but the one i recommend is usb c. It spits out the most power from that connection so get yourself a 100w c to c cable. I got a 10′ so i can have the panels in the sun while the electronics stay in the shade. Im also a tradesman and use my bose speaker everyday but the battery doesn’t go all day, but it does with this solar panel connected to it. I gave it 4 stars because it doesn’t put out nowhere near 40 watts because my power station tells me the what its recieving, but it does effectively charge my devices provided the sun is out. It folds down very compact and very easy to carry. Im satisfied with my purchase, but would recommend to hold off until a sale or coupon or a bundle offer. If it was a true 40 watt, it would be worth the full price, but it’s not so it’s not.

I am surprised, happily surprised. I do with all sincerity reccomend this panel.
As solar generators are becoming popular I whimsically bought a lower end generator. This of course incited my curiosity about, solar panels. The flexsolar 40w (by the way they should change their name or modify it, as ‘flexsolar’ pulls up all sorts of other products), is highly appreciable. Had it not been for two videos on Youtube, about this product, I would not have taken notice. I ran across this panel while researching other, solar generators. I was waiting for pay day to buy another panel that was on sale for $50, a 60w portable panel. I missed the sale. Then flexsolar popped up, I really liked the ipad pro 11″ size of the panel, when folded up. And, the youtube video was getting 35 x 38 watts on a cloudy day. (The clouds would make that number dipp significantly.) This was significantly better than other small, portable panels, that would only get half the wattage touted by their adverstising (anker, and others). It has been a several days since this panel arrived. Today is my first full sunny day. I am very famillar with a rav power 20,000 mah portable battery that I own. I charge it with an sd pd 61 watt and 30 watt ravpower ac cube, constantly. Lets just say I was not in the least bit displeased with the speed at which it was charging on solar. This panel has an old style usb port, a usbc port and a dc 5221 port. I was able to obtain from amazon a male to male dc 5221, a male 5221 to usbc male cable, and I already own the old school usb cables. The panel does not come with cables but if you have a usbc male to male cable you can use it for your usbc device, though I do reccomend a usbc battery rather than directly into your ipad, macbook air (there is no problem charging iphone or mac book air directly, but when you charge a brick, you do not have to leave your phone or computer vulnerable), they do sell usbc to lighntning cable for iphones. It is rather crazy that I can get input above a thirty watt wall charger, from direct sunlight. I could potentially buy another panel and parallel charge with an adapter, increasing my watt input potential. The panel is well built and in all probability will take a few years of abuse.I have lived through a few hurricanes in a major city with no electricity for in excess of two weeks. I also lived through the Texas power shutdown in our unusual freeze. This device would have been a game changer. In the freeze, even a small solar generator paired with two of these panels and the right cables in parallel, can run a 12v heating throw blanket, charge ipad, laptop, and run fans. A ten watt LED lamp is a god send after being in the dark all night long, not to mention all the books, and movies to make it through entertainment wise, knowing these solar panels can and will charge my portable batteries.I am very happy and am seriously considering another panel from flexsolar.*This panel could charge my phone in less than an hour of direct full constant sunlight.*This panel folds down into a shape comperable to an 11″ ipad pro, though definately thicker and heavier. 3 lbs maybe. It is not that noticeabke in a backpack. It is an apppealing pannel, shape and feel.*This panel could potentially charge my 20,000 mah usbc battery brick in three hours. A 42,000 mah solar generator battery in 6 hours.*This panel does not have “kickstands”, it does work laying flat, but something to prop it toward the direction of the sun would increase the watt potential.This is my first step into solar and I sincerely believe I have made a good first step.

lo uso già da tempo e mi serve per ricaricare non solo lo smartphone ma tutti quei dispositivi che sono dotati di una uscita USB. Data la sua maneggevolezza lo sposto sempre dove il sole batte in maniera ottimale

Wij hebben deze zonnecel aangeschaft voor het kamperen met de tent. Wij gebruiken daar nooit stroom. Nu met deze uitvouwbare zonnencellen, kunnen wij onze powerbank opladen en daar weer mee al onze telefoons, reader’s en elektrische tandenborstels opladen. Na ontvangst heb ik de zonnecellen even getest en in ongeveer 2 uren was de powerbank (22800) opgeladen. Was niet constant stroom. We zijn dus zeer tevreden.
