    Great solar panel
  

*by M***. on Reviewed in the United States on June 30, 2017*

Great solar panel. Works very well. The material is a hearty canvas. I like it except for the zippers on the back of the panel with the charge controller are crap. They are bright, shiny, loud, and cheap. I wish they had gone with a black zipper or something a little more in tune with the rest of the panel. I don't think the zipper detracts from the value at all, I just don't like shiny zippers. I would purchase this again.

    Very well made product, just doesn't deliver 21 watts
  

*by T***. on Reviewed in the United States on October 1, 2016*

I purchased two of these for a camping trip.  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.

I have had this Portable Solar Charger by Wildtek for a while now, so now it's time to list my personal pros and cons:Pros+Quickly charges my phone (Galaxy S7) when solar pannels are exposed to direct sunlight+It's fully waterproof (even the USB ports are plugged)+It's very compact and is easily be stored, compared to other solar chargers it is lightweight+Materials seem to be very durable (fabric, seams and zippers are of high quality)+Has an extra pocket to store away things like charging cables etc. which I find very useful+It has a 2 year warrenty, this should speak for itselfCons-Logo is a bit dominant (but that's just my taste)Overall this solar charger by Wildtek is a high quality product worth its money. Recommended buy!
