I plug the external charger into the wall outlet via the small black plug included in the box (and I'm also taking my cable I-phone).
The blue LED light up, the device is on. It loads, that's good.
This is fast enough to make it fully loaded.
After I slipped into the small bag and I put it in my bag.
Besides this small pocket is nice like that no possible raillure on the charger, even though I have this habit of keeping the protective film (for there is one).
I had to provide me with a cable for my I-Phone 5s (which is used on the I-Pad mini) because the black cable provided in the box is not compatible.
I plug one of the two charging device and the LEDs light up again.
My charger does what is asked and phone charging. Perfect!
He puts so much time to load than on sector. It's fast.
And it's great in the train because there is not all taking time to recharge our devices and which are large consumers of energy.
And I can load several times with one battery charge the external battery.
This is handy as this charger is small and fits easily in my small bag or it will rank easily in a toilet bag.
It is not very heavy and does not "plastic" either.
A nice device, I am very happy to own it.
Very good value.
