Hi everyone, I bought a Dynamite Passport Ultra charger used on eBay. I haven't gotten it yet but I know it's missing the DC power cord, so I'm going to make one. Can someone look at the DC power cord for theirs and tell me if the flat part of the plug is positive or negative? I'm pretty sure it's positive but I want to make sure. Thanks.

EDIT: Never mind I figured it out. Mods please delete. Thanks.
