Hello, I’m looking for a solid external battery supply which worked for you for powering the Jetson Nano. If that helps, I’ll be connecting WiFi nano USB Adapter, RPI Camera V2, keyboard, mouse to the JNano. The one I’ve found is 3.7V one that is used in Jetbot project (Iniu external battery), bu…

The INUI power bank from JetBot is 5V⎓3A (dual output), so it works with Nano no problem. In the JetBot bill of materials, it lists quantity 1 of them, so only 1 is needed. What the JetBot notes are referring to regarding 2x is that it has 2 outputs, not that you need 2 of them. I’ve used this 10…

That’s possible if the two outputs can work at same time.

I dont think you can. I read online that if you use the jumper to use the barrel Jack, it no longer powers from micro USB. If you want more power, I think theres a way to power from the gpio pins to provide 5v 3a to two separate pins, providing 30 w total.

That won’t work, but you may be able to adapt a barrel jack (or the 40-pin GPIO header) to a USB connection using an adapter like these: https://amzn.to/2JgvsId The USB-A connector on the lower-right could plug into the battery bank, and you’d solder a wire to the board and use a barrel screw ter…

So does that mean that the microusb or barrel Jack does not have any kind of current regulator? I’ve seen posts and from other sources that if supplied a higher current source, the micro USB would limit it to only 2 amps so it is recommended to get a slightly higher power source such as a 5V 2.4A in…

I think you’re confused about the role of “current” and “voltage.” Ohm’s Law is your friend! A load may attempt to “draw” some current (perhaps at a certain voltage.) It will attempt to draw all the current it needs, and no more. The current source (battery) will have some ability to supply current…

Ok thank you for the explanation but doesn’t that contradict what you just said about 3A power supply to the 2A USB as bad since it will only draw 2A? I get the idea of having a higher voltage to make up for the voltage drop from the internal resistance, but I’m specifically asking about using a hig…

A higher current rating is good for at least two reasons: it’s more likely to deliver a solid voltage at the current you actually draw the Jetson may perhaps instantaneously draw more than 2A for a very short while at times, which won’t be enough to heat up the cables/connectors, but would be a pr…

I have power bank with 5V and 2.5A but when I using this power source, my Jetson Nano can’t start. Can Anyone met this issue help me?

Would the INUI power bank also work with the Jetson Nano 2GB board?

@dusty_nv I went with the 25000mAh power bank. So I can just straight plug the 16-20V 4.7A DC output of this Krisdonia power bank into the DC barrel jack of the Jetson Nano?
