In general, how many amps can a dashcam capacitor take up to?
Would 7.5 amp fuse work? What about 10 amps?1 Amp should be sufficient, use a power supply rated for 2 Amps since they often can't maintain full output when they get hot.
The job of the fuse is to protect the wiring. If you are using 5 amp wire then a 10 amp fuse is very bad news if there was a short - the vehicle may get burned to it's shell, you should use a 5 amp fuse or less. If you have 10 amp wire then a 10 amp fuse is fine.Would 7.5 amp fuse work? What about 10 amps?
That cable is 2 amps maximum, 1 amp recommended. However it is the cable before the voltage converter that is the important bit since the USB cable should be protected by a current limiter in the converter, the cable before the converter is only protected by the fuse.I'm using this cable:

Will it be enough for 10 amps?
That issue has nothing to do with the fuse.Is there any way to get more current out of the cable? My dashcam isn't getting enough power to keep it on. I'm using a 15 ft cable to power my rear dashcam.
Voltage losses in a 12 volt extension should have zero impact since even if the hardwire kit only gets 10 volts, it will still give out the same 5.1 volts that it would if receiving 14.2 volts.Losses suffered in the 12Vdc extension should have significantly less impact on the power getting to your camera than similar losses in the USB cable.
Best to use a 2 amp, or 5 amp fuse with that kit, but you won't notice a difference unless there is a short circuit.I'm currently using the earlier mentioned cable along with these kits:
