I wanted to power a 3-6v dc mini motor pump using mobile charger do I need to use a limiter to control the current since motor requires only 130-220mA and charger output is 2A

    It should be fine, 5V is within the pump ratings, and 2A should be enough to cover the higher current needed to start the pump. –  Dec 19 '20 at 16:58

    JOSE LOWRANCE - Hi, When the helpful comment above from Brian Drummond is added, this previous question answers your main point, about whether a current limiter is needed. – SamGibson Dec 19 '20 at 17:21

    (Just FYI, although commonly called a "mobile charger", they are not actually a charger as they don't know anything about the specific voltage and current regulation profile, needed to charge the mobile phone battery. They are just a power supply. The charger is an internal part of the mobile phone, which gets its power from that external power supply.) – SamGibson Dec 19 '20 at 17:31
