theromisThe eBay unit's red and black surrounds on the outputs are reversed, although the polarity markings (+/-) are not. That particular mismarking makes me very leery = deal breaker. If someone was to take a chance with this, against my recommendation, I suggest they at least ask about the plug type, and connectors/accessories.
theromisMassdrop's image is correct. Red/+. Black/-. The eBay image has red/- and Black/+. That being said, I saw 2-3 RC sites which used the same wrong image the eBay seller is using.
