very good product in 2182

I buy this product because my wife often forget to charge his phone
it can easily charge one phone and one tablet
the defects are:
it does not charge the product that can be consumed a bluetooth headset
a battery that void too quickly can pass the 50%, but slower than the model 8000mAh
it is a heavy can but hey it's a battery
otherwise clutter its level is the size of a big style smartphone Note 3 but thicker
