My Arduino Nano and Pro Mini work perfectly on 3.7V but it does not even lit up when powered to 5.14V power bank on the +5V Pin (Pin 27)... no response whatsoever.
I also tried the example program "Button" (Arduino Software: Files/examples/02Digital/Button) to no avail, the board does not even blink.
I wire both the 3.7V and 5.14V power bank to pin 27 and ground... I also tried pin 30, VIN but that also did not work abviously.
Could somebody help? How can I make my arduino 5V work with 5V input!!
Thank you so much
I have an
Arduino Nano Clone 2.7V to 5.5V for ATmega328P (Link below)
Power Bank at 5.2 Volts (on multimeter)
18650 Battery nominally 3.7V but 4.1 V on multimeter (Sony SE US18650GR)
Voltage on the GRN/+5V Arduino terminal when connected to the battery is 3.8V, when connected to Power Bank is 0.87V
Could somebody help? How can I make my arduino nano 2.7-5.5V or Pro Mini work with 5.14V!!
Thank you so much

PS... I did search for a while on 3.7v/5v and arduino nano, but all I could find was how to power the 5V nano with 3.7 Batteries... :>) which works just fine.
When Connected to Li-ion battery (and working): 4.1v on the battery terminal and 3.8V on the board (Ground/+5V)
When Connected to Power Bank (and NOT working): 5.14v on the Power Bank terminal and 0.87V on the board (Ground/+5V)
You need “4.5v to no more than 5.2v” at the 5v pin to GND pin
Try running the Nano on ‘USB power’ and the LED board on the battery bank, use the image offered to you in post #2.
The battery bank GND will be connected to the Arduino GND.
“ 5.14v on the Power Bank terminal and 0.87V on the board (Ground/+5V)”
Please rephrase ?
I measured 870 mv between the ground and +5V terminals of the board, with the board connected to the power bank.
I am not even trying the LED board anymore, just the arduino board itself, it works fine connected to the battery.
I am connecting the battery bank GND to the Arduino GND
I will follow the wiring exactly and will at a capacitor.
Thanks and let me know if anyone has experienced this problem... maybe its the power bank.
By the way... the power bank does not like the board and resets itself after 5 seconds or so, it also gets warm.
The multimeter is reading 5.14v and the wiring is the same for the battery directly to the arduino or the same battery wired to the power bank board, which is wired to the arduino.
I will recheck though, I use this power bank to power other boards* and it works just fine.

Can you post a picture showing how you have the power bank connected? You should not simultaneously have 5.14V at one end of a wire and 0.87V at the other end

Done!!
Please note that the power bank starts blinking red and cuts power as soon as I power it to the Pro Mini... so please, just ignore the 0.87V.
The board works just fine power directly by Li-ion or Lipo Batteries or 5V DC Power supplies.
The power bank (see picture) works just fine with my phone and other 5V boards. It does provide slightly more than 5V.
I also wired the whole circuit with a capacitor (220 mF) and it also did not work.
Except that you went back and edited a previous post, so the display of your image (which really, you should have done) that LarryD made, is now broken. Please don't edit previous posts in this way, as you can see, it creates problems. There are instructions on how to post images in the sticky threads at the top of the forum.
The power bank may actually be looking at the data lines D+/D- that you chopped off the USB connector. They do have some charging functionality, for example to select between normal and fast charge rates - a shot in the dark, I admit.

I am sorry for the mistake, I will read all the instructions.
I will use proper wires and ditch the USB connector, I have a power banks that I disasembled and can wire directly to the arduino...
Proper wires also did not work!!
I also powered my arduino nano directly to the mini-usb port, using the same power bank and it worked perfectly!!!!!!! what is going on???
This is baffling me... it simply does not work. I also tried another power bank and also it doesnt work.

Dear Shannon,
I managed to power my arduino nano directly to its Mini-USB, on the +5V/GRD Terminals. I powered the board using the same set up we are discussing, the power bank and the chopped USB cable. Please, see picture attached.
Can anyone help? How can I power a Arduino Nano or Pro mini using a power bank wired to the proper +5V and GRN terminals of the arduino board??
larryd:
I believe some power banks require a load on the two USB data wires before the bank is allowed to output current.
Dear Larry,
Thanks for your input... I also tried 2 other power banks, to no avail.
I am starting to think about giving up. it is a pitty because this power bank provides an easy to use on/off button and battery protection.
It simply wont work... except if I wire the power bank to the mini-usb of the arduino nano.
I am loosing hope.
It is indeed true that I am able to power a Pro Mini and five (5) 8x8 with a generic 5V power bank.
The power bank is wired to VCC and GND pin on the Pro Mini through a microUSB breakout board which has the microUSB connector for the power bank.

Not necessarily. Image links are usually broken when cross posts are amalgamated as has happened here, though I see no warning notice to that effect.

I received a PM from the OP about this thread.
Now that is strange considering you made no prior contribution!
