For camping, the batteries are perfectly suitable, because such a nearly 40-device allowed better times a night on the toilet a campsite invite, as the phone itself.
Not only the batteries have made us very happy, and others that we met, we were able to go give some "juice" and so a little longer allow them to observe the rain radar.
The battery has 4 USB outputs for 4 end-users, each with different amps. 0.5 for "odds and ends", 1.3 for smartphones, 1.0 for most Nokia phones and Sony are 2.1A for the iPad and other pads.
This is also all over again in the poor translated instructions.
It should be mentioned that I had first 2 times ordered the black battery. One of them I had tested before actually designated camping holiday. Since the battery is shipped almost fully charged, I could charge all end users properly. But when I was at home, I realized that not load the battery left. Quick unpacked and checked the other, I found out that it was actually on the battery and not in the charger, or anything else. So the battery went back to Amazon and I ordered a new one. For this super fast and easy way of exchanging "Thank you" at Amazon. The Battery was the white one euro less and heal.
Side by side, I find the white much nicer and not as prone to scratches.
What matters however is mainly the inner values and the are super in this part! Holidays never without! no matter where!
