  • Solar Panels ChargersBuilt-in 1* QC3.0 USB-A max 18W , 1*PD 2.0 USB-C max 18w(5v-3A/9V-2A/12V-1.5A) and 19V DC (5.5*2.1mm) max 40W outputs to directly connect and charge phones( (Android and Apple) , iPads, power banks, small power stations and other daily electronic devices. 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 FEATUREIntegrated 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 PanelMade 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.

    • cool gadget
bough this as an emergency way to charge to charge my phone in case power when out. got a chance to test it out a few time. surprisingly work very well. wish the 60w + is lighter so i could upgrade and have a more effective gadget. currently charge time is slightly slow but in an emergency or long camping trip, it should work fine. love how i dont have to carry anything extra beside just this fordable panel ... show more

    • 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. ... show more

    • Great charger
Charges well and quickly with good sun. A bit heavy to pack but probably worth it for a group. Does not hang well when using the one clip they provide. I need to design a rigging system.

    • Great addition to my travel kit
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. ... show more

    • Works great.
Review Image by Wes Wes
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. ... show more

    • Work perfectly!
I go this to charge my Anker 548 power bank, once I ordered the correct adapter (which is the XT60 cable). It worked better the. I had hoped. Definitely puts out the 40w.

    • Finicky Solar Angle
(For the 40W version) This is still the highest wattage output Solar panel I have found that can be put inside of a backpack. I would only recommend getting this if it’s sub $70.it does have some issues. If you manage to get the panel perfectly aligned with the sun with absolutely no obstructions you can get like 38W of power. The issues is that even the tiny shadow of say a USB cable obstructing a corner of one of the segments drops the solar output to like 7W…we are talking 1% obstruction…as was also mentioned it’s very particular with sun angle. As an example I was hanging the panel from a pole outside my house to get the 10:00AM sun. The panel at a vertical angle got about 13W but changing the angle by a mear 1-2 degrees produced ~30W… now I know that solar efficiency is dependent on solar angle, but this is ridiculous… the marketing around hanging this on say a backpack will simply not make enough energy to matter. We are talking 2W on average during my tests. The short story is if there is a singe segment not exposed to sun the the panel no longer makes any energy at all… If you do get this also plan on some kind of way to angle it appropriately. (As a note I’m getting my measurements from a Sharge (previously Shargeek) battery bank) ... show more
