5,2 volts to much for the raspberry pi?

Former Member

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:

    LOL, I was just about to link my blog on that, Thanks John, gets the info to Bruce quicker.

     

    To summarize, there is no need to use a 5.2V adapter, if you have a good 5V one already. If your having issues then look to your USB cable, there are so many crappy ones out there, also if you have multiple devices on the USB, use a powered hub instead. If you have a multimeter, try different cables and measure the volts across TP1 and TP2, pick the cable that gives you the best voltage (Highest Voltage reading)

     

    This alone should fix any power related issues you have.

     

    Oh, and a 5.25V adapter is running the chips right on the edge of their MAX ratings, this I do not recommend.
