Powering issues


I am having powering issues with the MKR 1400 wich I can not seem to solve.

I wrote a simple script to send an test SMS to my cellphone. When I power the MKR to the USB port of my PC it works fine. If I am not mistaking the MKR pulls a short burst of 0,07A when making connection and sending the SMS.

When I power the MKR with a powerbank it does not send the test message with the same script. The powerbank I use is a 15.000mAh and 2A. So this should be sufficient or am I missing something here?

Thanks in advance for any tips/advice.

There's some information on GSM communication issues caused by power on the MKR GSM 1400 here that might be relevant to your situation:
