ok, if my ps vita 1000 model not 2000 charges by 5v can't i use a micro usb with a 5v to charge it without harming the battery?

Yes, you can use a micro USB cable with a 5V power supply to charge your PS Vita 1000 model without harming the battery. Just make sure that the power supply is 5V and not higher, as using a higher voltage power supply can potentially damage the battery.

you know i'm talking about the one with preipotory charger

I apologize for any confusion. If you are referring to the original PS Vita model (PCH-1000), which has a proprietary charging port, you will likely need to use the original charger or a compatible replacement to ensure safe and proper charging. Using a micro USB cable with an adapter or converter may not provide the correct charge voltage or current, which could potentially harm the battery or the device. It is recommended to use the appropriate charger for the best charging results.

it's a 5v, tho just a different type of charger but it can fit!

If the charger you are referring to is also a 5V charger and fits the proprietary charging port on your PS Vita 1000 model, then it should be safe to use for charging. As long as the voltage and current are compatible with the device, you should be able to charge your PS Vita without harming the battery. Just be sure to always use a charger that is within the recommended voltage range to avoid any potential damage.

wait so your saying if i take a micro usb and put into a usb c with the sam voltage it would charge the device?

If you are using a micro USB to USB-C adapter or cable to charge your PS Vita 1000 model, it is not recommended. The PS Vita 1000 model uses a proprietary charging port that requires a specific type of charger. Using an adapter or cable to connect a micro USB or USB-C charger may not provide the correct voltage and current for the device, which could lead to potential issues or damage. It is best to use the original charger or a compatible replacement that is designed for the PS Vita 1000 model's charging port to ensure safe and proper charging.
