So first: The charger fits the description (output 5V - 1 A 700m) and it is also from Samsung (at least according to legend), but it loads the S5 just too slow. The original Samsung charger (I have the S5 and can therefore see it is starting 5 - 2 A 2000m) and invites therefore much faster. I'm not an electrician, so I can only imagine that when this charger here just not enough "power" flows as in the original chargers or other product lines. If I 30min the phone on power have been using this charger and he has just 3-5% more battery, the charger does not help me zero. I do not want to load 8 hours while the original Samsung mobile phone invites S5 charger to the wall outlet in about 90min!
