Need dc connector for SkyRC MC3000

The dc barrel plug on the end of the switching power supply for my MC3000 got crushed off. Anyone know what size I would order/part number etc? So I can repair?

Thank you! I was hoping to only have to put a new barrel plug on though.

just measure outer diameter of the plug…
standard size for barrel plugs is 5.5mm OuterDiameter 2.1mm InnerD (5.5mmx2.1mm)

afaik the connector on this device is center-positive.

there are barrel plugs that are designed to be soldered to a cable by hand.
if you don’t have a soldering iron, consider getting one, it’s quite handy.
also order appropriate heat shrink.

otherwise there are barrel connectors that can just be screwed but it’s clunky and a wire might come loose, make a short and fry the power supply.

in any case you just need sidecutters, screwdrivers, needle nose pliers and optimally a multimeter for checking polarity and voltage.
otherwise red tends to be positive and black negative.
