Who expected that the Battery you get full within a few hours with the ET-1 maybe should internalize the technical details again.
Therefore I do not understand the bad reviews.
I have the battery immediately once fully charged via the PC and then my Iphone 3Gs loaded with it. Works beautifully.
I also had a couple of technical questions and I have turned directly to the company and was very friendly, knowledgeable and patiently answered.
Unlike competing products, the ET-2 panel can klippsen fixed wonderfully on bag / backpack and umbrella. Once daylight falling on the panel already loads of the battery without having to really align this to the sun, artificial light is used.
I have the battery fully charged and connected it to the Iphone and was on the beach listening to music all day, watch movies and play 3D games. Under normal circumstances, would the internal battery, as probably everyone Iphone owners know after 1 hour at the end was. But not in connection with his own small, I call it lovingly "power plant".
I have a large panel simply thrown to the umbrella and firmly clipped without actually paid to the sun from, including I have the battery pack placed so that it is not in direct sunlight.

Then strained Iphone and asked the panel next to my couch and then connected via the battery in the iPhone.
You can use the iPhone and charge at the same time via the panel the battery again.
It is not possible to connect the Iphone directly to the ET-2, which is a good thing, because as voltage peaks are avoided which could possibly be harmful.
My Nokia 33 slider phone can, however, directly upload.
Personally, I would find it nice when the battery would have more capacity and you could connect several panels.
On the edge mentioned:
The battery was half full and was in the midday sun after 2 hours completely full (all 4 lights lit)
I recommend the ET-1 in conjunction with the ET-2 without hesitation is highly recommended for this price category.
In order to avoid confusion. The ET-2 only works without problems if it was coupled with wird.Ich ET-1 only just my Nokia phone download them directly, but I do not think that the point of it ist.Ich it've tested only once.
