I've already purchased extras.
I have to admit, I am somewhat skeptical of the claimed efficiency of better than 21%, making it one of the highest efficiency solar panels available in the mass market at this time. It is possible that it is true, but considering the converter that is taking the electricity from the cells and making USB standard power *has to* have some loss associated with it, it seems unlikely.
Being a tech minded guy, I test stuff. Its what I do.
As everyone will tell you, if using a solar charger, it is better to use a battery pack to store the power when the sun is shining and charge your devices from the battery pack. This solar charger is not a battery pack, it simply takes sunshine and creates 5V output through standard USB ports.
**Update** 4/25/15
Bright sunny day today, measures around 165,000 lux (using my Galaxy S5 and "GPS Status" app on phone) just past solar noon in southern new england.
Today I used 2 Drok USB power meters, one in each output port and two devices (phone and battery pack) to pull maximum power from the panel.
I was pleasantly surprised to see a total charge power of 1.9 Amps!! (divided between my battery pack and phone)
This is a significant increase in power 'generation' from the last test, and is almost as powerful as the fastest USB wall chargers available today, so to me, this is huge! It still falls about 50% short of the 20W claim but as previously noted, solar panels never hit their claimed power production numbers due to a standard which is laboratory based and effectively impossible to achieve in the real world. Additionally, there are conversion losses to be accounted for with this product.
All in all, the X-Dragon High Efficiency 20W Solar Panel is a pretty awesome way to have real, usable USB power anywhere the sun shines.
Highly recommended!
** UPDATE ** 3/16/2015
Bright sunny sky today, measures at around 110,000 lux, but still, ides of March sun @ ~41°N Latitude
Initially I hooked up two high drain devices to see what the maximum output would be but it never got higher than it did with one high drain device, specifically, my Ravpower battery pack for portable charging of any usb powered device.
I saw a peak power output of 1.37A @ 4.91V for a total of 6.72Watts output power. On one hand this is disappointing considering the stated 20Watt ability of the solar charger, BUT considering that spec is STC (standard testing conditions) no solar panel ever produces the stated STC spec in the real world.
Using my phone as a point of reference, the battery in my phone is 10.8Watt hour capacity, charging at the measured value of 6.72watts *Should* take about an 1:40 (one hour forty minutes) to charge fully from dead.. Which is about what it takes when plugged into an AC powered adapter.. so I am completely satisfied with the purchase at this time.
Conclusion, it does the job it is supposed to do, creates free power from the sun to charge your USB powered devices
Original test 3/15/2015
**TO BE FAIR, conditions are not ideal for testing today, being PRETTY OVERCAST at the moment and ~41°N latitude.
Using an app on my phone (Galaxy S5) , I measured the currently available light at around 11,000 lux.
I set up the panel angled somewhat to the south, after a couple seconds the LED lit up on the power outlet so I plugged in my Portapow USB power meter in line, and plugged in my Ravpower battery pack as a load to take the charge power.
The meter indicated 4.93V @ 0.34A which means it would probably charge your phone, but fairly slowly.
Most plug in USB wall chargers produce between 1 and 2.4A at 5v so by comparison this is a fairly slow charge.
The battery on my phone is 2800mAh so at a .33A charge rate it would take 8.2 hours at current conditions to fully charge the battery from dead.. if the phone was off.
Bottom line, in overcast conditions the power production is fairly pitiful, but that was somewhat expected.
This review may be updated again when/if I am able to test the unit under even better conditions.

As I returned on leave I purchased this product and tried it hoping I could take it back with me on duty and have a reliable device to charge my things while on patrol.
I received this product and immediately rushed to my backyard to test it out.
It is a clear sky and full sunny day.
• My Ipad 2 when I plugged it into the device recognized and showed it was charging, after 20 minutes of direct sunlight the Ipad went from 40% to 44%. This is acceptable
• My Ipad 3 when I plugged it into the device did not recognize it and so did not receive any charge.
• My Note3 cell phone when I plugged it into the device recognized it but after about an hour and several tries checking the charging cable and the suns position still had no charge what so ever. I checked the charging cable with my car usb plug and immediately started to charge the device.
• In conclusion, this device is a NO GO for me. I need a durable and reliable product.
-------------------------------------------------------------------------------------------------------------------------------
UPDATE:
I am now editing my review for the following reasons:
I have been contacted now at least 5 times via email from X-DRAGON asking to please change my review because the negative is hurting them. I will do no such thing for the following reasons:
1. Honesty is the only option, anything else is wrong.
2. This product is overpriced compared to a more reliable, durable and powerful product such as the Anker Solar Panel 14W system that’s below.
http://www.amazon.com/Anker-Dual-Port-Charger-PowerIQ-Technology/dp/B00E3OL5U8/ref=sr_1_3?ie=UTF8&qid=1446564853&sr=8-3&keywords=anker+solar+panel
3. This product advertises a 20W output which is not only misleading but a straight out lie and deceptive to customers
4. This product was made with cost effectiveness in mind, which is why it can only offer flimsy hanging loops that will break off in time, if they wanted to produce a product well made with the customer in mind they would have spent more money and made proper hanging metal rings like the Anker Solar charger has.
5. This product will only charge effectively in direct sunlight, don’t believe anything else said. The Anker 14W charges my devices even in cloudy days
6. This product even though is inferior to others on the market is being sold for more money, with a slashed price of $149.99 and advertised for $56.99 is a complete rip off to everyone. If they cared about the customer their price would be comparable to the devices capabilities and it would probably be in the range of $29.99, and even at that price I would not purchase it.
7. The fact that they have contacted me over and over asking me to change my review leads me to believe that it has happened now many times and so most of the reviews for this product are not accurate due to buyers feeling bad and adjusting their reviews later.
In conclusion not only is this product inferior and offering misleading information but I now see that this behavior of misleading and false advertising runs within the company itself.
This is one of the reasons our country is the way it is, greed:
(Intense and selfish desire for something, especially wealth, power, or food)
It makes me very sad to know I fight for freedom while others in our own country are tearing it apart.
