USB-A and USB-C allow you to charge both electronic devices at once. But don’t recommend that DC and USB ports use toghter in case of the charging is a little slowly. Note: Solar Panels cann’t store the power.
【SMART IC CHIP TECHNOLOGY & SAFETY FEATURE】Integrated IC automatically detects the connected devices and provides the optimized charging, and an included LED light shows the charging status.FlexSolar ensure 100% safe charging with overcurrent, overheating and short-circuit protection.
【Portable Camping Solar Panel】Made for mobile camps and off-grid adventures, the 40W foldable solar panel is perfect for longer trips when you need more power without sacrificing portability. With a small size of 8.0x 11.1x 1.8 inches (when folded) and a lightweight design of 2.86lbs(1.3kg) that can be easily squeezed into your backpack, offering portability and simplicity.It is also a must have for stashing in an emergency kit.
【HIGH SOLAR CONVERSION & IP67 DUSTPROOF WATERPROOF】Highly efficient solar panels convert 24% of solar energy into free energy in enough sunlight. IP67 dustproof waterproof and ETFT laminations make the solar panel work under unexpected weather and last longer than other PET solar panels and the most durable panels available, withstanding wear and tear better .Note: the junction box isn’t waterproof.
【PACKAGE & SUPPORT】You will get a FlexSolar Solar Charger, 2 Carabiners and User Manual.

A mio avviso un prodotto che mantiene le promesse
il peso reale è di 340g, un peso aggiuntivo più che accettabile per avere la possibilità di ricaricare su sentieri.
Con sole leggermente velato e inclinazione ottimale del pannello sono riuscito a spremere 7,5W misurati con strumento, a livello del mare, sulla costa ligure.
Mi aspetto che averne almeno altrettanti a 2-3000 metri di quota con sole pieno non sia difficile
Con questa potenza in circa 5 ore e mezza si può caricare da zero un power bank da 10.000mAh su 3,7V di cella (cioè un power bank commercializzato normalmente da 10.000mAh) che consente almeno 3 ricariche complete del cellulare e dello smartwatch.
Facendo un po’ di attenzione con l’uso del cellulare, modalità aereo, 20-25 foto al gg. e consultazione mappe offline circa 20 volte al giorno l’autonomia diventa pressoché infinita anche in caso di 2-3 giorni di brutto tempo, senza aver mai bisogno di caricare dalle rete elettrica.
Aggiornerò la recensione dopo un giro di 6 giorni sulle alpi completamente off-grid, vedremo.

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.

it for traveling it good only for phone but my phone alway said charger low , but not sure this solar can do 30w i had to use power station DC input: 10-25V/5A, 60W Max + USB-C PD input: 60W Max seller said this solar ” our usb output of our panel is only 12V(max) power can reach to 18W i recommend for power bank or small device

Bought this item for an upcoming camping trip. The item arrived on time in an simple amazon bag. I tested that the usb a and dc jack worked. I skipped testing the usb c port due to laziness.
When at the camp site I was able to use the usb a and dc jack but the usb c port was not working. Even when in full sun light. When i got back i messaged the manufacturer and they were able to make it right and provide a warranty on the device by replacing it.

En cuanto lo sacas a la luz comienza a trabajar automáticamente. Cuando hay MUCHO sol, carga los dispositivos incluso un poco más rápido que la corriente (no lo cuelgo, lo coloco en el piso de la azotea). Recibe energía incluso cuando está nublado (aunque carga lentísimo, obviamente, pero funciona).
Muy buena opción para dejar de depender tanto de la corriente.

I have been using this solar charger to charge a small power station to use while tent camping. It has worked great! The power station has run a small fan and kept my phone charged, and this solar charger ha had no problem keeping the station charged.

My wife and I travel a lot in a converted van that has a pretty competent solar-powered house electric system. We seldom camp in campgrounds with hookups, so we rely on the house system a lot. I bought this to have an easily portable alternative method for charging the many USB rechargeable devices we use in our travels – our phones, camera batteries, power banks, flashlights, etc. This has worked out very well in the short time I’ve had it. In the right conditions, it charges about as fast as plugging a device directly into the house system. It’s compact enough to be easy to store, even in our very small camper. It seems to be very rugged, and, except for the USB interface, it seems pretty weather resistant.

I recently returned from a 19 day rafting trip on the Grand Canyon and this solar panel did a great job of keeping all my devices charged. One thing I’ve encountered with solar chargers in the past is that at only 5 volts the length of your USB cable makes a huge difference in charging rate. Where I might charge at 10 watts with a 6 inch cable, a 6 foot cable would only do 2-3 watts.
Unlike those, this panel uses PD charging via USB-C so it can exceed the normal 5 volts of USB. Testing it out in my back yard I was easily able to charge at 20 watts, and this was in Oregon late in the afternoon. The battery I was using only supports 20 watt charging so I wasn’t able to verify 30 watt output, but given that it would do 20 in less than ideal conditions I fully expect it would perform to spec.
If you’re buying this make sure the device you are charging supports PD. I recommend charging a PD power bank with this and then charging your devices off of that so that you don’t have to leave your device in the sun. Also, you can get USB-C cables with built in power meters which is a great way to monitor the panel’s performance.
