I’ve been looking at what options I have to power the E-M1x via USB PD and it is not as easy as it would seem with all the options out there.
The E-M1X needs a power bank that is compliant with USB PD. The “output” specifications must offer either 9v 3a, 15v 2a, or 15v 3a. That’s it. If it doesn’t offer one of those three, I would not use it…or it may not work at all. Not sure I would take the chance with other units not meeting the required specs.
A lot of the power banks out there list a lot of options…make sure you read the output spec. A lot of power banks do not offer one of these. So far this is one that I found. One of the few. “Powerbank on Amazon”
I have no affiliation with that product or amazon, there is no benefit to me if you order it. I have not tried it, and you do so at your own risk! It is not a recommendation, just one unit I found at the moment while doing my research. Once I get one and successfully confirm it, I will post an update here. Have you found any good power banks that work with the E-M1X that you recommend?
