Review: Great Portable Solar Panel! - Holy Moly! I freaking love this Solar Panel! Now I don't have to worry about not being able to charge my phone and small electronics when I am out camping. Now, for the performance (in terms of wattage), it will depend (just like any other solar panel), on the amount of sun, angle, etc. - so make sure that you actually put it into direct sunlight. Some of the things I love about this product are: 1. Super sturdy design 2. Easy storage 3. Great performance 4. Waterproof So glad I purchased this! Thanks again Wildtek! Review: Worry free way to keep my camera charged at music festivals without any electricity - I am very excited to take this camping with me, especially to music festivals and to burning man to charge my phone and camera and external battery so I can keep the pictures flowing. The waterproof design is going to make using this so worry free. The panel is very sturdy and all the components feel very high quality. It's an all in one easy system with the stand built it (so pieces and parts don't go missing when you are packing for a trip). ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01G4GQDUE | | Additional Features | Portable,Lightweight,Waterproof | | Brand | Wildtek | | Built-In Media | 1 x Solar Panel | | Compatible Devices | Smartphones, Tablets | | Compatible Phone Models | Apple,Htc,Iphone,Nexus | | Connectivity Technology | USB | | Connector Type | USB | | Customer Reviews | 4.1 out of 5 stars 126 Reviews | | Enclosure Material | Monocrystalline Silicon | | Included Components | 1 x Solar Panel | | Manufacturer | Wildtek LLC | | Mfr Part Number | 4J-IWEJ-KPP0 | | Model Number | 4J-IWEJ-KPP0 | | Output Voltage | 5 Volts (DC) | | Portable | Yes | | Power Source | Solar Powered | | Special Feature | Portable,Lightweight,Waterproof | | Total USB 3.0 Ports | 2 | | Total Usb Ports | 2 | | UPC | 688713033005 | | Wattage | 21 watts | ## Images ![Source 21W Waterproof Portable Solar Charger Panel with Dual USB Ports - Image 1](https://m.media-amazon.com/images/I/91kI+bmv9rL.jpg) ![Source 21W Waterproof Portable Solar Charger Panel with Dual USB Ports - Image 2](https://m.media-amazon.com/images/I/91pO2D-e68L.jpg) ![Source 21W Waterproof Portable Solar Charger Panel with Dual USB Ports - Image 3](https://m.media-amazon.com/images/I/912FAn-ZMIL.jpg) ![Source 21W Waterproof Portable Solar Charger Panel with Dual USB Ports - Image 4](https://m.media-amazon.com/images/I/910btn7YlxL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Portable Solar Panel! *by J***O on May 14, 2017* Holy Moly!

Thanks again Wildtek! ### ⭐⭐⭐⭐⭐ Worry free way to keep my camera charged at music festivals without any electricity *by C***A on April 13, 2017* I am very excited to take this camping with me, especially to music festivals and to burning man to charge my phone and camera and external battery so I can keep the pictures flowing. The waterproof design is going to make using this so worry free. The panel is very sturdy and all the components feel very high quality.

The goal was to operate two 9V fans from two USB Power Banks and 9v/12v USB voltage converters. By any measure I was successful at keeping everything running for three days thanks to the Wildtek 21W panels. This has fantastic construction. They fold down easily, open easily, the zippered pouch is very useful to store cables when the panel is not in use. The "legs" fold out and provide the ability to adjust the panels with the sun as the day goes on. There are two USB ports to charge from and a rubber cap to close the ports to the elements when not in use. For me, good design wins all over. In terms of performance, the experience is a bit more mixed. It seems there is a uniform problem of manufacturers overstating the actual performance of their panels. Wildtek doesn't seem to be immune to this. Mathematically, they claim 21W maximum output. However, I could get nowhere near 21 watts of power out of it. I tested, used, and reused the DROK USB tester with various equipment - PowerBanks, phones, fans - and the best power output I got was 12w. Technically this panel could get you up to 2.1A per USB port (5v @ 2.1A = 10.5W). I have several devices that can pull that kind of load - iPhone 6s, Lumia 950XL, RAVPower 2.2kwh Power Bank.. and even loading both ports of two DROK testers and adding the power draw together, 12w was the max I could get. I tried this in South Florida on clear & lightly cloudy days as well as Key West on clear days in September. I'm glad I made the assumption the panels would generate half the rated power and purchased two. Otherwise I couldn't have been able to keep everything charged on my trip. I think it would be tough to be a manufacturer claiming a premium price for a "12 watt" panel when all of the competition claims double that - yet performs nearly the same. Perhaps some regulation in the industry would help out, in the meantime we have Amazon reviews. Overall I love what I got, it's reliable, performs well, and is well made. I would buy this again. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/30732082-source-21w-waterproof-portable-solar-charger-panel-with-dual-usb](https://www.desertcart.be/products/30732082-source-21w-waterproof-portable-solar-charger-panel-with-dual-usb) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-06-21*
