The other main advantage of this battery is the technique used. iSmart is actually the battery's ability to adapt to the power of your device. She will deliver the maximum charging power so that your device will recharge faster than the manufacturer loader. And I love it. I advise all buyers to systematically favor the iSmart.
In 7800, I was able to charge my smartphone, my pole sefie, my mp3 player and my tablet. For the latter charge was not complete but it's amazing.
Regarding charging this battery, it will charge in four academic hours. However I have a charger iSmart so that it is a bit faster.
I do not regret a thing but I will not take away a star, it is the presence a single output to recharge his camera. I would have liked USB outputs so you can connect two devices simultaneously. At the same time, under the battery capacity, output is justified.
Ultimately, this battery is not heavy, is a great ally in my travels. Indeed, I now have to charge my perch selfie my gopro, my phone and many other things. And not just for the weekend. Not heavy in my bag, it will troubleshoot any person in the family.
