21W Portable Solar Panel, Foldable Solar Panel Charger(5V/3A), IP67 Waterproof for Camping, Hiking, Backpacking, Ultra-Fast Solar Phone Charger with Dual USB Ports for iPhone, iPad, Power Bank

Its really well built and feels very durable, it has a nice small footprint and its foldable for sticking in your bag.Using it in normal direct sunlight im regularly getting 7W of generation in sunlight, even without sunlight I'm still getting 1-2W regularly. Just like the solar on my house is made great by the battery in my powerwall, adding a usb power bank makes this even better. In a camping /backpacking situation i would use this to power a battery bank that i could use to run anything i needed to at night, in an emergency it works great to charge my iPhone directly if i needed it to. It's inexpensive and high quality, i definitely recommend it.

It's a no frills solar panel that performs as claimed. It charged my Google Pixel 8a from 57% to full charge in one hour twenty minutes.Great for a power outage.

The panels come well wrapped for shipping. Upon opening you'll realize that this setup is the real deal. Very robust. Looks like these will last a long time.Hooked up to my cell phone with the included usbc cable, started to see increases immediately. Charge led let's you know when there's enough light to provide a charge. Good circuitry, great value.

Have been playing around with it for about a week now and it’s a super solid product. Charges my devices quickly and the fact that it’s water proof is super nice. For the money you’re getting a lot

Did a quick test and in about 15 minutes I got 5% on a dead Pixel 7 & that was at 5 PM.It was 10AM and the panel was producing over 2A!This panel WORKS!Great for emergency power to usb devices or as a alternative to shore power.

iPhone was at 30% charged. Hooked my iPhone 15 Pro to this solar panel, (I live in CA) and it was a cloudless 70 degree day, and my iPhone was fully charged at 100% in 1 hour and 10 minutes! Only solar panels that I've tried that actually WORK!

This is the first portable solar panel I have owned and I must say I am quite thrilled to have it. It folds up nicely and is simple to use, allowing me to charge any of my USB devices with any USB cable since the panel provides both a USB-A and a USB-C output port.I measured the power production of the panel using a dedicated USB power meter and a dedicated USB load device and the power generation of the panel seems to agree well with the advertised power values.The panel is encased in some type of siliconized plastic material that appears flexible, of appreciable thickness and durable. I believe that it will fare well over time and repeated use and/or stowage.A three-section folding panel such as this allows the panel to conform to non-planar surfaces (like your backpack or a boulder or a log) and allows the user to stand the panel vertically without support, but also contributes to a certain "floppiness" to the panel. You can't get the panel to remain flat using its own rigidity (as would a single, flat panel). Each of the three sections of the panel must be supported. This is the price of portability, I suppose. It would have been nice to have a rigid support system made of a simple bracket(s)/rod(s) that could be attached along the back of the panel for this purpose which might also be used to provide other mounting options such as an adjustable-angle kickstand, etc. But hey, a little DIY and you can probably cook something up yourself using something as frugal (and multi-purpose for survival/camping use) as chopsticks and duct tape, or a wire clothes hanger.I can rest easier now knowing that even when armageddon might be upon us, I will always be able to charge my flashlight and ensure that there will always be a light available in dark times, or on the brighter side, that I will always have a source of power available on extended, super-lightweight camping/hiking excursions. This solar panel is definitely on the "Essential Survival Gear" list.

I got it to slide into or clip onto my backpack on backpacking trips. It's working great charging my phone even keeping it in the shade during the daytime. I'm very happy with it, exactly what I wanted.
