Welcome to the Dell Community [NAME]  You are correct. Since you have a SMART power system it will "pull" only the "Wattage" required. As for the powerbank. If the Barrel end is the same dimentions and the Power output matches or exceeds the system requirments, it should be compatable. Best regards, U2
Hello Have a new 3515 Inspiron 15 Wanting to improve available time on battery It shipped with 11.25V 41Wh G91J0 battery I dont use normal HDD bay and want to replace battery with 54Wh V6W33, however, it is 15V output Does the voltage output change matter for the mobo or will the mobo just pull the voltage it needs, thus leading to longer life while off the charger? I was also interested in 7051L barrel type powerbank, however, I cannot determine if it is compatible with this model (its not listed in the compatibility list on the dell page for the powerbank) Any confirmation help would be appreciated thanks, Kitndavj
