I have a Xperia Z5 Premium, but my charger is broken, can anyone have the model name for this phone.
I want to use the last Quick charge for my phone, and I think in a charger UCH12. I dont know, I need help in this...
Thanks.

Hi @Richard_nosy, sorry to hear about your charger. 
As @vikri wrote, the Xperia Z5 Premium supports Qualcomm Quick charge 2.0 and you can use either the UCH10 or the UCH12 to quick charge your Xperia Z5 Premium. Do note that you will need to use the cable included together with the quick charger (UCB11).
If you are planning to buy a new phone later on, I would recommend that you take a closer look at the UCH12 since it does support Qualcomm Quick charging 3.0 which our later models supports.
I hope that answers your question!
Z5 stock charger uch20
Z5 support QC 2.0 witch is compatible to use uch10
*Z5 didnt support QC 3.0 (CMIIW)

I have almost the same problem. I have a Sony Xperia Z5 Compact phone and a UCH-10 Sony Quick Charger that supports Qualcomm Quick charge 2.0. Which cable works better with UCH-10 Sony Quick Charger: UCB11 or EC803? And is there a difference between them in relation to their ability to charge the phone battery faster. I am asking this question because I have both of these cables but unfortunately my UCB11 cable doesn't work because the USB plug was pulled out by my two-year-old son at the time and I wasn't able to check and compare the performance of the two cables with the quick charger to see which of them works better. Now I use the UCH-10 quick Charger with EC803 cable and I am not sure if it was the cable that came with the quick charger or it was the cable of the original UCH-20 charger which came with my Z5 Compact phone. The same goes for my UCB11 cable as I don't remember if it came with the UCH-10 Quick Charger or with the UCH-20 charger of the phone.
Greetings from Bulgaria!
Hi @Todor_Isaev, welcome to our forum and I'm sorry to hear about what has happened to your UCB11 cable. 
When charging your Xperia Z5 Compact with the UCH10 charger, I recommend that you use the UCB11 cable that was included together with the charger for the best effect.
EC803 is the cable that was included together with your device, same as the UCH20 charger.
I had a look in the Sony Xperia eStore for Bulgaria, however from what I could see you are not able to buy a new UCB11 cable directly from here, so I would recommend that you get in touch with your Local support team and have a look with them as availability for accessories may differ between markets, and they are experts on your specific market!
I hope that helps!
Hi, I have the same problem.
I've looked a lot for "ucb11" cable but couldn't find it in Iran.
My question is that can I use "ucb16" instead of "ucb11" ?
