Interesting Charger - Little Documentation to Tout Its Features.
Amazon Customer✓ Verified Purchase•March 23, 2018
Two high current outputs - good for an IPAD AIR2 and an Android phone needing a SuperCharger.
Tried it out when we had sunshine last week! Keep the panels at 90 degrees to the sun as much as possible.
Keep from under trees, beams and anything that might put a shadow over the panels.
A screened in patio will also reduce the output somewhat.
If 2 of the folded adjacent panels are covered, there is not enough output to do charge anything.
If there are intermittent clouds, the load may indicate "not charging".
I'm not sure how the peak power tracker ("MPP") resets itself. Since it is theoretically possible for a peak power tracker to "lock up" at a lower power transfer from the panels, there --may-- be some need to force it to reset by covering it up and opening again in full sunlight if it stops charging for no apparent reason. (No documentation explains the MPP circuit which is only indicated in a picture.)

Looks good and we’ll built

Bought it to charge power banks while on long trips and while camping. 2A output is what attracted me to this one over others. Looks like a quality product. It's cloudy and rainy here in the PNW so haven't had a chance to test it. Will update my review when I the weather cooperates.
-"“"”"”"”"”"”"”"”
Update -4/23/2018
When charging a single phone or iPad that has a battery discharged to The current output will display 2.5 -3A for a short time, drop to roughly 1/2 of that for a moment, then display 2-3A again. Changing my rating to two stars, as I have serious doubts that this could provide anything close to 4A out. I'll be doing some more testing with a current meter and different devices to see if I can figure out what's going on. I do believe it will work well enough for my intended use, of charging a large USB power bank.

Seems well made. Under-priced! and a VERY good value. So far works very well. AMMETER is a big PLUS for this product.

Seems well made. VERY Under-priced!
I have used tis for the last 2 days when the sun was full out. I got 2.something AMPS out of when charging one or two smart devices and a power pack.
The built-in AMMETER is a huge plus on this for me.
At this point, I highly recommend it. I just ordered a second unit !
Please note that the item had a contact info slip in the box. The phone # is disconnected, the Web site they list (BigBlue.com) is not "on" and their email bounced back. It's a good thing that Amazon stands behind this.
If you are considering a 20-something WATT folding solar panel, you definitely should get this none. If you're not very happy with it....Amazon will take it back.
So far, I am very happy with this. If that changes, I'll update this review.

I've only had this one day but so far it is pretty good. Got 3.8A output in middling spring sun.

I've only had this one day but so far it is pretty good. I have an Anker powercore dual charge input power bank that will take 2A on each input. I connected both inputs to this panel and pointed it at the ball of nuclear fusion in the sky. The ammeter on the panel ran all the way up to 3.8 and I stashed the powerbank in the shade underneath. A couple hours later my 20,000mah powerbank had all charge lights lit and was tapering off down to 1A in current draw, from 50% starting charge.
So far I'm loving this panel other than a couple logistical decisions they made on where to locate the usb connectors (why not put that box on the back, out of the sun?)

Charges fast, Seems durable

The solar charger worked great. After leaving it in direct sunlight for only 2 minutes my phone went from 84 - 90% on the Samsung S6 Edge.
It actually works better than my Anker solar panel charger, and this one actually displays the charge rate so you can get an accurate amount of sunlight.
The most sunlight I got in north eastern Texas allowed me to display a 0.5 on the charge, which is what gave me the fastest charge rate. Definitely great for emergencies. I keep it in my car now in case I break down or my car battery dies.
If you do a lot of camping or hiking, this solar panel is a great addition to a camping kit. It has four holes to be able to securely cinch down the solar panel on the back of a backpack with some paracord. It also comes with a zipper pocket to put phone into, not to mention spare cables for charging an extra device.
