Connector Type: DC Barrel Plug (Male)
Size: 4.0mm (Outer Diameter) x 1.7mm (Inner Pin Hole)
Is this the same as the 4.0 x 1.35mm size?
No. While the outer 4.0mm size is the same, the 1.7mm internal hole is larger. If you use this on a 1.35mm pin, the connection will be loose and intermittent. Always measure the inner pin!
Will this fit my Sony PSP?
Yes. The classic Sony PSP typically uses the 4.0mm x 1.7mm standard (often distinguished by a yellow tip).
Which terminal should I solder as Positive?
Standard convention for these devices is Center-Positive, but you must verify your specific device's label or original charger before soldering.
