FocusFoto Full Decoded BLS-1 BLS-5 BLS-50 Dummy Battery DC Coupler with USB Cable for Olympus OM-D E-M10 Mark II III IV Pen E-PL9 E-PL8 E-PL7 E-PL6 E-P3 E-P2 E-PM3 Camera Battery Power Bank

The issues I mention, are ALL RELATED TO THE DESIGN OF THE OM-D's CAMERA BODY, not this battery adapter itself.Be aware of them, before using this adapter for applications like long outdoor time-lapse.So far, the adapter worked as advertised and no problem powering up the camera and different lenses. More tests needed (after I add better weather/moisture protection).#1 The OM-D E5 is not designed to accommodate a pseudo-battery with an external cable ==> other cameras have a notch in their case & additional seal to close the door and seal cable outlet#2 The open door poses a challenge to mount the camera with ext. power onto a tripod, especially when using the 1/4" thread. It is not impossible but you need to be careful not to damage the door.#3 Also avoid moisture intrusion into the camera body through this open door. At night, dew can creep into many places.

Plugs into a USB outlet and provides constant power to my camera. Perfect for streaming or recording for a long period of time without having to worry about the battery level.
