Kastar PSP-110H 2-Pack Battery & USB Charger Kit

Two-battery kit for original PSP models

The Kastar PSP-110H kit supplies two lithium-ion cells rated at 1500 mAh and a dual-slot USB charger that fits Sony PSP-1000 through PSP-1010 and the PSP Fat series. Each battery delivers 3.7 V and 5.6 Wh, matching the original PSP-110 specification. Travellers and retro gamers can keep one cell in the console and a spare in a bag without hunting for a proprietary wall wart. The charger accepts micro-USB or USB-C input so any phone adapter or power bank can top up both packs.

Dual-slot charger sustains 800 mA per cell

When both batteries are seated the charger maintains a steady 800 mA output to each slot, avoiding the current taper that single-port adapters often show after the first few minutes. The LCD panel reports individual voltage rise toward 4.2 V so you can see when a pack reaches full capacity without guessing. Heat stays low because the charge current never exceeds the rated 800 mA per channel, making overnight top-ups practical. The 5 V 2-3 A input requirement is met by common USB power bricks.

USB power limits define charge speed

The charger draws up to 15 W from a 5 V USB source, so a 1 A port will lengthen the cycle while a 3 A port keeps both slots at the rated 800 mA. Micro-USB and USB-C inputs are provided but the kit does not support Qualcomm Quick Charge or USB Power Delivery negotiation; it simply uses the available 5 V rail. Users without a 2 A or higher USB supply should expect longer fills. No AC cable is included, so a separate USB power adapter is required.
