I tried other manufacturers 5V regulators, they regulated 5V, but after charging there was not enough current to turn on the FPV camera. No, it works great. These iFlight 5V regulators can accept 2S battery as input and regulate 5V to power your AKK FPV camera well. The size is also small. I installed this so my RC car can now stream the FPV camera to my goggles. The only thing I would like is that the output pads are on the opposite side of the input for soldering.
