Picking up a battery isolator and need to calculate the size of the batteries to hide under the seat.
Yes, about 350mA with wifi off and 400mA with wifi on, that is at 5V so half it for your 12 volt battery (you will loose 20% in the converter).Has anyone ever measured the actual draw of the a129?
3 home alarm batteries connected via a battery isolator would solve all this.
if you're thinking of those small SLA type batteries I'm not sure this would work well
I'll just go down to the battery wholesaler and get what I need. A simple battery isolator is available from Amazon for next to nothing and separates the circuits so that the camera would draw from my new bank of batteries and not drain the starting battery. The zendure and other usb battery banks are just toys. Not sure why I didnt think this out earlier.
Toys? All because the Zendure you purchased won't run your camera for a week or more you dismiss the entire product category? Personally, I've been using power banks to run dash cams for extended periods of time with great success, but I don't ask them to do things they aren't designed for.
I think your maths is a bit out ... well, maybe more that just a bitYes. A usb battery is a toy. Spend $75 on a proper battery and an isolator and get multiple weeks of run time and do it properly.
That is all.
Actually, that Zendure X6 that charges at 45 watts might be a good cheap choice. How fast can you get 24 hours of charge into your little SLA battery?The zendure and other usb battery banks are just toys. Not sure why I didnt think this out earlier.
Yes - toys. Using a usb battery bank plugged into a cigarette lighter socket is a costly and ineffective response to something that needs an isolator and a proper battery system. It's only because I can only assume people's knowledge of batteries and charging systems here is limited to things like USB batteries that other more effective and logical solutions aren't posted.
