Nice little article - does well what is intended to

Received in Portugal on a small package.
Was intended to keep a large 20000 mAh powerbank on, even if the connected device didn´t signaled any load.
Worked well with two different brands powerbanks.
Very pleased with it. Congrats to the builder. * * * * *

Power Bank Keep-Alive

One of the most useful gadgets I've come across in a long time. I'm mainly using my power banks to drive DIY Bluetooth speakers, and so far, this has been quite a pain in the backside...
While this is a simple and easy to build little circuit, being able to source it pre-assembled in a 3D-printed enclosure is really handy. And the price is more than fair.
Thank you very much; I'll certainly be back for more ;-)
