Hi all.

 

Having bought a new dashcam which has the facility to perform time-lapse recording when the vehicle is unattended I've had an idea on how to power it without draining the car battery. 

 

I know specialised electronics are available to monitor the state of the car battery and turn off any connected devices when the voltage gets too low but I have in my "really useful one day" gadget box a 20,000mAh battery for charging iPads, phones etc. and I'm thinking I could use that instead.

I've rigged up a 12v supply that switches on/off with the ignition via a piggy back fuse. I'm thinking that I could feed that to the battery ( via the usual 12v-5v converter) and connect the dashcam to the battery output. Has anyone already tried this and if so was it successful?

Dashcam Battery pack lets you record whilst parked.
