Hello,
I’m interested to buy this product. But before that, can someone help me find out how long is the cable?
Besides, in the product description it says ‘a 5.5x2.1mm “center-positive” barrel connector’. Does it mean the adapters connector is ‘inside positive （+）outside negative (-)’?

P.S. The product’s code is ‘RB-Spa-108’ on page:

Hi mildred and welcome to the RobotShop Community forum.

Indeed the inside (or center) of the connector is positive (+5VDC) and the outside is negative (0VDC). As for the length of the cable, it is ~150 cm.
