Powerbank Battery for a Dashcam

You can tell a capacity is an outright fake just by the weight and physical size. You cant fit 50,000mAh 5v (250Wh) of power in a small case that weighs 290g. It would need to weight at least 1kg+.

Some less shady brands will state the capacity of all the cells, even though they are in series.
 
Zendure A2 + support Pass through and seem to do the trick, i have two of these powering each channel and they seem to just work. I have not tried daisy chaining them.

Griffin Survivor supports passthrough too but the CS never seems to reply.
