Generally I am quite satisfied with Mumbi products. I have already several times display films, Smartphone Cases ordered from this supplier etc. But this no-name product has a quality that is already rare in branded products. I bought it for my LG Optimus 4X HD (P880). With 1000 mAh output current it loads very fast, it will not even begin to warm and most importantly, it crackles not know how my orginales supplied with the phone power supply. This product I had the feeling that I have to write my comment necessarily here. The positive reviews were crucial in my purchase, because you have to pass on their own positive experience. The excellent quality has to be rewarded by good feedback.
Update on 31.12.2014: After a few months the thing has given up the ghost, making it ended up in the dustbin. Externally, I could see no shortage, but apparently the electrical inner life is dead. Only two stars instead of five.
