Hello, I have built an electronics project, that uses 0.003A@5V 95% and 0.090A@5V 5% at the time.
I powered it by 2200miliamp/h Chinese power bank.
By my calculations it should keep my project running for about around 200 hours. But from the testing results I get only around 75 hours.
When I measured current before power bank's circuit - it showed me 0.020A@5v 95% time and 0.150A@5V 5% of the time.
So biggest increase caused by power bank circuit is at 95% time , when there is small load.
Is there any way to get around this problem (simple way) , for example with capacitors and transistors to turn off load from power bank and power it by capacitor ,when small load is needed?
Or I just need more efficient battery circuit?
Thanks!
