I've received ordered X10400 (http://www.aliexpress.com/item/origi...671968791.html), sended by Netherlands Post. I can confirm good quality, authentic Xiaomi's code, weight (279gr with case, also from AExpress, and attached usb cable). I'm testing this pbank now in my LG G2 (D802). I haven't yet charger doctor (ordered) to check values like votage etc but for now in Elixir app I see good value 1.6A when is charging (I wanted to have >=1.5A), so it's very well. For now, 10400mAh, I suppose ~7500mAh in reality, is OK for my 3000mAh battery in G2.
BUT, I've also 4xPanasonic's 3400mAh 18650 (unprotected) so, I'm curious, it's possible to replace in future installed LG's 2600mAh to my Panasonic 3400mAh, in this Xiaomi powerbank ?
Have you tried thid kind of replacing ?
