very easy to use. very light and compact for transport. 2 large bright LEDs: purplish red: charging. blue: battery charged. thanks to the size of the LEDs that you can be on top by plugging (no earth connection bothers) quickly and we see good when you can disconnect the charger. I noticed that it took about 4 hours to charge the battery, which then contained little remaining charge. I now have 2 batteries for my phone and I think it's fine. I change the battery as soon as one is empty. I do not have enough back in time to give the longevity of the loader but I hope it will last as long as it suited my expectations, besides its price is very reasonable.
