Well equipped, battery + USB cable + safety net.
Recharging takes time with the charger iphone (normal), the use of USB while charging is impossible.
The battery does not heat up when charging and discharging, the build quality is good.
A star less still for the indicator light which is certainly convenient, but flashing all the time. I wish I could turn it off.
I will update the review if a problem were to arise
Edit: Conclusion after several cycles:
The battery never heats.
It allows indeed to charge nearly 3 times an iPhone 5S. It is specified (no surprise), even if it is only about the theoretical 4000mAh against 6400mAh.
The indicator light completely kidding:
- The first full burden iphone 5% amputated ... The second removes 60% ...
- The indicator is positioned incorrectly, the 0% is not around 11 noon but, suddenly, the whole circle is shifted.
