Beautiful USB power source on the go. (Update: very good long-term experience)

I chose this Power Bank (= external USB battery) in white paint to test and am quite surprised by the elegant appearance and the form that is different from the other Power Banks something. The oblong shape is elegant, but now has no practical advantages.

With 145 grams no lightweight ...
with about 10000mAh but a decent Kawenzmann, which allows you to recharge a smartphone or a tablet a few times.
Cable and velvet (like) Case included in delivery. Very chic and practical too!

2 outputs allow to load even 2 units in parallel. The 4 LED's are at least a clue to see how far developed the battery or is loaded.
More than 500 charging cycles he should join. This information inspires confidence.

[Note: I the unit was left free for testing. My opinion has not been influenced by the manufacturer. I could of good quality and usefulness of the device - already over weeks and months - convince].
