I bought the Lenmar - PowerPort Gold to Charge my Galaxy Note 3 while away from an outlet. Unfortunately when fully charged the PowerPort was only able to charge my Galaxy Note 3 up from 24% to 57% before dying. The PowerPort was able to fully charge my Plantronics Voyager Edge and Galaxy Gear 2 without any problems. I recommend the Lenmar – PowerPort Gold for emergency use only or for a smaller mAh battery. I am pleased with my purchase.
