Power your camera continually, and without interruption, with the Tether Tools ONsite Relay Power Kit for Sony NP-FW50 Camerasfrom Tether Tools. Equipped with a built-in 7.4V, 1,200mAh lithium battery and a 5 VDC input via USB, this system will provide power, while being connected to an external power source for a nearly constant source. When connected to a 2A USB battery pack or an AC adapter, the ONsite Relay can still be able to provide a constant supply of power to your camera, and thanks to the internal battery the system will support hot swapping of external power sources. An LED indicator light will shift from green to yellow to red to show battery percentage so that you will not accidentally lose power during a long time lapse or video production. This system is compatible with numerous camera systems through the use of a separately available coupler. This coupler fits into the battery compartment of your camera and acts as a dummy battery to supply power.

Q: 10. When camera/coupler/Tether Tool is operating, suggestions of how to keep battery drain from exceeding the simultaneous charging? I have found it will not do both at the same time. Thanks.

A: It works for me. Keep in mind you have to use a power bank or charger that outputs at least 2 amps (the one i use is 2.1 amps). I tried with a power bank that only outputs 1 amp initially and that gave me the same problem as you have.
