5,2 volts to much for the raspberry pi?

Former Member over 11 years ago

Hi, I was Just wondering if it is okey to use a 5,2 volts power supply with 1 ampere instead of the regular 5 volts power supply?

Thanks for all answers :-)

RasPi is designed for the USB power voltage range 4.75V to 5.25V, so a "5.2V" supply should be fine as long as it's not producing more than 5.25V. Also, there will be a small voltage drop across the Micro USB cable and RasPi's polyfuse F3 (Model A/B) or F1 (Model B+), so it's nice to have a little more than 5.0V. The actual drop depends on how much current RasPi is drawing as it performs different activities.

Here are some useful links:

John/Peter as you both say the .2 V is lively to be a benefit if anything. Just enough to allow for the volt drop getting in to the Pi. Also the PSUs tend to sag a fraction when underload unless they are quite good ones
