Hi, I am in doubt about the power of the arduino with 5v, I would like to connect it in a powerbank of cellular and I would like to know where to make the connection, can I do it by the usb? Can I make the jack connector, can I make straight into the vin or 5v pin? And where I must be careful not to destroy my arduino? thank you
If the powerbank has a USB port, might as well just use a USB cable into the USB of the Arduino.
But your Arduino's not a cellphone, so it might not turn the powerbank to charge mode. I don't think powerbanks act like simple batteries, they need some signals from the chargee. (That's what I understand, anyway.)
You certainly won't have any luck supplying 5V to Vin since it needs to be >7. It also warns under Documentation, Power here that supplying 5V to the 5V pin is not recommended since it's on the wrong side of the regulator. (Although Inthink nobody worries about that if it's a reliable 5V.)
Hi,
What do you mean by "power bank"?
Do you mean something like this?
If so the USB connection from the bank will be 5V, so you can just plug the Arduino USB lead into the larger socket.
