https://devzone.nordicsemi.com/f/nordic-q-a/60703/powering-nrf9160dk-through-powerbankHi! I would like to power the DK through a external power bank. This leads to led5 blinking rapidly for a while and then turning off. I assume this is because of the debugger IC, so i was wondering if there is a way to bypass/disable this? Thanks inen-USTelligent Community 13Tue, 28 Apr 2020 14:15:37 GMThttps://devzone.nordicsemi.com/thread/247138?ContentTypeID=1Tue, 28 Apr 2020 14:15:37 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7d30e3a0-749c-4e2e-a960-8327230c0bb8ketiljo<p>Ok, maybe better to use a LiPo battery&nbsp;instead then. This is a common problem that power banks shuts off when the the current draw is low.&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/247092?ContentTypeID=1Tue, 28 Apr 2020 12:28:12 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f05c2527-fcaf-4060-aa34-99970ff3c13cmolviken<p>I have now tried with two different power banks (only available), and both give the rapid blinking response. I connected the power banks to the micro-usb socket, and used a multi-meter to measure the socket pins for given voltage supply. While LED5 is blinking, it show 5V, and then drops to 1.8 (power bank shuts off).</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/246885?ContentTypeID=1Mon, 27 Apr 2020 13:43:15 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4b78d7c5-0605-4c52-84ce-a518ffaa8a68ketiljo<p>I might be the power bank that&#39;s the problem. Some of them will turn off the output when the current draw is below a certain limit. Check the supply voltage if this is the case or not. If so, see if you can find a different power bank that doesn&#39;t do this.&nbsp;</p><div style="clear:both;"></div>
