I Charger 1 = P1/U Charger = 13.42W/5V = 2.684A I Charger 2 = (P2-P1) / U Charger = 2.376A I Charger 3 = (P3-P2) / U Charger = 1.672A I Charger 4 = (P4-P3) / U Charger = 1.408A I Charger 5=(P5-P4)/U Charger=1.76A Nima I am not wrong, P=50W is far greater than 30W ah (data for reference only, non-professional equipment) 1, this brand in the consumer word of mouth polarization, and some say potholes, and some say very good, but my last 29 to buy a four-port usb socket used very good, otherwise it will not buy, electronic What is the product? 2,59 An original price will not be considered, you can add money on anker or other brands better and more stable 3, work is what is good, daily use 4, 79 The price of the three really can not buy a loss can not buy
