Do I need to put the current limiting resistor of just go direct?

A very low cost and easy solution for me was this:
MINI USB socket charging:
1.tear apart a 5v usb car charger



2.the spring is +("c" type ring is -) and there you will connect your source, solder the plug of your coise properly.
USB has 4 pins, outer pins are your output. Solder properly the plug of your choise.
In my testing it worked either with 2cell or 3 cell lipo, both gave me 5.18v.
Be careful for positive-negative as it will damage your camera, also check voltage because below some point, about 4.70v, camera shuts off and if it is over 5.20v it might damage it.


3.done
I use one with my 5.8ghz tx and one as a portable usb charging station.
TESTING:
With 5.18v usb output I used the camera in continuous, 20min parts, recording for over 6 hours with 3cell 2200mah lipo as source and everything worked fine. Not once, but many times outdoors. Temperature was about 15 Celsius.

Here is the portable USB charging station


Here is FPV use, I have two extra parallel leads to power transmitter and OSD through LiPo's charging plug.
