It works for me. Only gripe is it gets warm to the touch. I used laser thermometer and it got to 80 degrees F but it cooled down while it was charging. It does not charge faster than stock if charging only 1 battery. Charges 3 batteries in 80 minutes simultaneously including the RC. It does not have storage mode but it is way cheaper than DJI 3 battery charger with storage capability. I put my batteries in storage mode by charging them to 50% (two bars) or if I have full battery then I just fly the bird until 60%.
