How Long to Charge a Sony PSP Go?

Charging a Sony PSP Go from empty to full takes about 1 h 3 min with its standard 5W charger. The battery holds roughly 3.7 Wh, and this page estimates the time for every common charger wattage, using the Lithium-ion (Li-ion / Li-Po) chemistry it actually uses.

The Sony PSP Go's compact design meant engineers had to make strategic trade-offs, most notably with battery capacity. This handheld—beloved for its sleek sliding mechanism and digital-first approach—demands a thoughtful charging routine from users who want to maximize their portable gaming sessions. The lithium-ion battery inside benefits from regular, moderate charging cycles rather than deep drains followed by emergency top-ups. Keeping your PSP Go topped up whenever possible during downtime, rather than waiting for the battery to dip critically low, tends to preserve the cell's longevity over months and years of use.

Unlike some gaming devices that tolerate wide temperature ranges during charging, the PSP Go performs best when charged in cool to moderate environments—a practical consideration if you're gaming in warm climates or during summer months. The device's compact form factor also means heat can accumulate more readily around the charging port and internal circuitry, so allowing adequate cooling time between intensive gaming sessions and charging helps the battery maintain its responsiveness. Players who build a habit of charging overnight or during idle periods, rather than attempting rapid power-ups during active play, typically report more stable performance and fewer battery-related quirks over the device's lifespan.

With the fastest charger listed here (Fast charger, 18W) it takes about 17 min. With the slowest (Original charger, 5W) it takes about 1 h 3 min. Released in 2009, the PSP Go featured a compact sliding screen and reduced battery capacity compared to previous PSP models.

Frequently asked questions

How long does it take to charge a Sony PSP Go?
From 0% to 100% with the standard 5W charger, it takes about 1 h 3 min. Using a faster charger shortens that; using a weaker one extends it, see the table above for exact numbers.
My PSP Go doesn't seem to hold a charge as long as it used to—is this normal?
Yes, this is a natural part of lithium-ion battery aging. Over hundreds of charge cycles, the PSP Go's battery gradually loses capacity to hold energy, similar to rechargeable batteries in any portable device. This degradation typically becomes noticeable after a couple of years of regular use. You can slow the process by avoiding complete discharges, keeping the device cool during storage, and charging it regularly even if you're not actively using it for extended periods.
Is it safe to leave my PSP Go plugged in overnight?
The PSP Go is designed with charging safeguards, and modern lithium-ion batteries stop actively charging once the battery is full. However, leaving it plugged in continuously for weeks or months—especially in warm environments—can subtly stress the battery over time. The best practice for long-term device health is to unplug it once fully charged, store it in a cool place, and top it up every few weeks if you're keeping it on the shelf. This approach balances convenience with battery longevity.
How is this charge time calculated?
We divide the energy needed (3.7 Wh times the percentage you're charging) by the charger's effective power, which is the charger's wattage times the battery chemistry's real-world charging efficiency (85% for Lithium-ion (Li-ion / Li-Po)). The same formula powers both this page and our API.
