External charger which I hope will do wonders! Used (2 for 2 bought smart phones) yesterday for the 1st time, impeccable. He quickly recharge your battery (one supplied with or the original one, I tried both). All in a package stamped Samsung, which has official-looking, with serial number. The supplied battery is manufactured in Korea and assembled in Vietnam while the original is made in Japan and assembled in Vietnam. All at an unbeatable price! Be careful though, there are no USB cable supplied with 3! I use the one supplied with the laptop, but at that price ... I wonder if I will not order another one! Sold and shipped by Amazon, fast delivery, easy to open cardboard. I recommend this article!
