Charging a Dead PSP Without Its Charger: Not Possible Safely

You cannot charge a PSP without its dedicated charger (or a verified compatible replacement). The PSP requires a specific voltage/current profile that only its AC adapter or a compliant USB-PD source provides.

Why Improvised Charging Fails / Is Dangerous

• PSP-1000/2000/3000: Barrel jack (5.0V / 2.0A = 10W). USB port (mini-B) is data only — no charging circuit connected.
• PSP Go (N1000): Proprietary USB connector (5.0V / 1.5A). Standard micro-USB cable will not charge — missing sense resistors.
• Voltage Mismatch: Phone chargers (5V/1A–3A) may seem close but lack the PSP's charge-controller handshake → overcharge, battery swelling, fire risk.
• Battery Chemistry: PSP uses 3.7V Li-ion with built-in protection circuit. Bypassing it removes thermal/overcurrent safeguards.

Legitimate Solutions

1. Official / OEM Replacement: Sony AC Adapter (PSP-1000: ADP-100; 2000/3000: ADP-110; Go: CSP-100). $10–$20 on Amazon/eBay.
2. Quality 3rd-Party (UL Listed): Brands: PowerA, Insten, KMD, Nyko. Must specify exact PSP model. $8–$15.
3. PSP Go Only: CSP-100 cradle (charges + TV out) or proprietary USB cable (rare).
4. Portable Power Bank (USB-C PD) → Only for PSP Go with correct cable: Requires 5V/1.5A fixed PDO + correct resistor ID. Not guaranteed.

If Battery Is Dead (0 V) — "Reviving"

• Li-ion below 2.5V/cell enters deep discharge protection. Standard charger may refuse.
• Do NOT jump-start with 9V battery / bench supply. Fire/explosion risk.
• Replace battery: PSP-1000/2000/3000 → 1200/1800/2200 mAh (Cameron Sino, Wasabi). $10–$15. Easy swap (1 screw).
• PSP Go: Battery soldered. Requires microsoldering or full rear housing swap. Pro repair ~$40.

Bottom Line: Spend $10 on the correct charger or battery. Improvising risks a $150+ console and your safety.
