Allpowers XDragon 20w
Charges two phones/devices relatively well in direct sunlight. Amperage ~ 1.3 to 1.5A Samsung Note 4 in direct Hawaii beach sun. This is a very good solar panel for the price. I was trying to decide whether to buy this or the Poweradd 20w panel and decided to go with this because it was half the price of the Poweradd. I was slightly doubting my purchase decision because the Poweradd 20w 4 panel model has some awesome performance capability.
The first thing I noticed after opening the X-DRAGON was the cells looked advanced. They are supposedly made by Sunpower, a reputable solar company. They obviously harness a good amount of energy because there is an impressive output.
I look forward to taking this camping to charge my usb battery bricks and sharing it with family and friends. I recommend purchasing a USB Detector display adapter to maximize performance regulation.
I think the X-Dragon is a perfect solar panel for anyone on a budget who needs a reliable charging panel in case of power outages or off the grid scenarios. It fits well into the sleeve of a standard sized backpack and is lightweight enough to not slow you down. Personally I would not recommend a lower rated panel as slow charging may become encumbering on-the-go, or there being lack of sunlight.
I would have given this 5 stars if it picked up more ambient energy without direct sunlight. But it does the job, charges phones and tablets just fine in the sun.
