Awesome but bulky,
Verified Purchase(What is this?)
This review is from: KingMansion 4200mAh External Battery Case for Sony L36H/Xperia Z Black (Electronics)
I love this, except its bulk, but then that is a price to pay for the charging capabilities of this little pack. It totally charges my XZ from flat to full in about an hour. It's solidly built and seems pretty robust. I use it out on building sites so having the bulky case isn't a problem in my work trousers, out and about however and it is a little too bulky.
