    Solar…I love solar… I am a huge outdoors and camping guy. The wave of solar powered products now affordable to the average consumer has created a whole new way to experience life outdoors. It is also a necessity for emergency uses. You can never prepare enough for a disaster. I have bought two of these solar panels but this one seems to be doing the job of the other one also!! I thought it would be much bigger but it’s almost the same size as my other one and it puts out twice the power!Portability-It is Amazing that a 40w panel can be fit into such a small and versatile package. I was very impressed. The only thing I could ask for is a built in stand. But I under”stand” that would mess with the portability of it. It’s no problem grabbing a few sticks and leaning it against them.Power-ok, 40w is enough to power anything you could ever need while camping. It’s enough to directly power a laptop computer. I was skeptical about this so I put it to the test. Around noon I unlatched the battery in my laptop and went outside. I laid out the panel in the sun and hit the power button. Like magic, my laptop turned on. It was really quite amazing. And the panel was laying flat! It would catch much more energy if propped up and facing the sun.Quality-The entire thing is made for durability. I could not be happier with the materials as I can see this charger lasting me a very long time while seeing a lot of usage.I am planning to buy a portability solar generator that powers AC so I can use this charger to top it off. This panel is more than enough for what I’ll need. The way I see it, camping, emergencies, you cannot have too much stored electricity.

    I’ve been on a solar kick lately, with my first purchase being a solar powered battery bank. The solar panel that came on the power bank is not exactly designed to charge it from 0 – 100% in any reasonable amount of time, but rather provide a little extra bit of juice with every chance it gets from the sun. I wanted to be able to charge my portable devices and power banks anywhere there’s sunlight, and this product definitely fits the bill. I tried measuring the output with a multi-meter, although it was partly cloudy out I was surprised to measure near the full wattage advertised. It successfully charged my power-bank via USB and with the provided DC connections, it makes it possible to power smaller devices like my Chromebook which normally need AC power in order to gain a charge. Folded up it’s quite compact, easily sliding into a backpack or duffel bag, you will need an area to really lay it out in a direction best facing the sun in order to maximize your charging wattage. Simply hanging it vertically from a carabiner won’t get you there. All in all, I’m very happy with the product and its usefulness in the event of an emergency.

     When I bought this product, I thought it as more of a curiosity than a product I would actually use. As a person that has an interest in renewable energy (even have a small micro-hydropower plant at home), I thought this would be a good way to start learning and getting some hands-on experience with solar panels. This seemed like the right product to buy as it promised easy installation while being very mobile. At first, when I received the product, I thought that it would be nothing more than a trickle charger to keep a power bank alive or something of the sort. Nevertheless, while taking it on a trip to the lake, I realized it was much more than a simple trickle charger. The first day I tested it, was at around 3pm on a slightly cloudy day and I was surprised to see that it did, in fact, charge my phone! The next day that I tested it, was a much more sunny day with little to no clouds and boy, I was impressed. It charged my phone as quickly as my iPad charger would and it had no trouble in charging my laptop! It definitely provides a LOT of power while under direct sunlight! What I love most about this product is how easy it is to carry. It is light and when folded up, can be put inside a backpack or bag with little effort. It is definitely a must-have for people that like camping or hiking in remote places. To make it an even better addition to your gear, I would suggest hooking it up to a battery bank (any high-quality one should work) and that way, you should be able to charge up the power bank during the day and use the battery bank at night or when it’s overcast. The panel is made of high-quality materials and it definitely can take some rain or sand and still work just fine! I would even get one of these to leave on a boat! All in all, this solar panel has really impressed me with its light weight and power and it now comes with me whenever I go hiking or camping!

    This is easy to hook up and charge your items. The device comes with a variety of attachments so any item you can think of can be charged. You must unfold the device completely to charge the items. There are holes with which you can hang the device if you have more vertical surface available. The speed of charging is comparative to having it plugged into electricity. There is no battery storage so you charge the device when you have daylight. I was impressed that not much daylight was needed and I was able to charge even inside a vehicle or inside the house. So nice to have this alternative as we lose power often and we also like going camping. When traveling in another country it is nice to have this alternative as well although it does take up some space in the suitcase.

    I love collecting survival gear. Something about being prepared just makes sense to me. This solar charger can really help you in a time of need. I’m currently using this with a cell phone power bank but plan to get a higher capacity battery to use with this. Imagine a scenario where there is no power and you need to power some lights or recharge your cell phone to make an emergency phone call. The applications are endless. I love the idea of getting power from the sun. You don’t need a power bank to charge your cell phone as you can plug your phone directly to this charger. It’s charges pretty slowly but not as slow as you would think. It’s about as fast as the included iPhone power brick when in direct sunlight at the right angle. I love that they included every possible adaptor you could think off and even better is that it store nicely inside a pouch within the solar charger. This things is built very nicely and feels like it will last for a long time. It’s not light but I wasn’t expecting it to be. I could definitely see myself storing this in my trunk for emergencies.

    This is an amazing panel. I’ve been tinkering with a setup that allows me to charge my 48Ah battery and is still portable enough to bring on trips that don’t require the large battery backup. I think I’ve found just the thing. First of all, let me say that there are only two things you can charge directly from this panel: 1) Any USB device, & 2) A laptop/notebook whose charger is rated @ 19V DC. Pretty much anything else will require a solar charge controller or a “power-width-modulated” power-supply. You’d need these because the voltage coming from the solar panel is not constant; it varies depending on the amount of sunlight it gets. I won’t go into the details, but you can get a fairly inexpensive charge controller here on Amazon.As with any solar panel, the amount of current it outputs can vary greatly by just adjusting the angle of the panels to the sun. This one is no exception so to get the most out of it, you’ll need to make sure you’re pointing it as directly to the sun as you can. However, even at an angle in the morning, I’ve measured the voltage output at 23 volts with no load. That voltage is consistent with the rated 2 Amp charging capacity of these panels. 40 Watts / 23 Volts = 1.74 Amps So at 18 Volts you’d see 2.22 Amps. I am however aware that even at 2 Amps, it takes almost 24 hours of sunlight to fully charge my battery backup (although it’s never at 0 Amps, sooo…).Anyway, I think with a little understanding of what can be expected from this panel it can be used in a multitude of situations with great success. With this, I have replaced a smaller foldable panel and a larger rigid panel because this one can serve both purposes and still be folded away for transportation.

    This is a fantastic solar charger, I was impressed by how quickly it charged my phone at home. We love boondocking with the camper and it’s going to be nice to have a way to charge electronics that doesn’t drain the 12V onboard.It also charges battery banks if you want to rotate your power source and take advantage of the sunny days.

    This solar charger worked very well. I noticed that even when there was a little overcast, it was still producing current. Did not have a way to really test the output, but found no fault in it’s ability to charge my backup battery packs for device charging like phones and pads. It worked well enough to buy another in the future.

     This solar panel is very compact. If fits easily in to my backpack and camping gear. I love the fact it charges my portable Iforway AC generator.

     I purchased this solar panel with the intention on using it for my camping festival event. This is my 2nd solar panel I own and I’m very impressed on how portable the panels have become!This solar panel is very light Weight, made of very sturdy high quality material, able to withstand camping conditions,I hooked it up to a battery pack to charge in order to have portable energy in a battery and it worked flawlessly!Make sure to aim it directly at the sun and adjust the position as the sun direction changes, in order to get optimal performanceThis solar panel included 1 usb and one normal output, allowing me to charge anything from an iPhone, portable speaker to a battery pack. This product includes different tips for power chords, so it makes charging different devices a breeze!Overall I feel this solar panel is strong enough to use for Camping or when Hurricanes come thru Florida, but also portable and ability to fold up makes it easy to store away when not in use:)I would highly recommend this panel for anyone that needs a decent amount of watts for powering devices at the beach, camp, or any outdoor activity!
