How fast will a dash cam drain a battery pack?

Black Box G1W plugged into a 20,000mah external battery pack. Fully charged battery, how long can the dash cam stay on until the battery runs out?

Answer:

hard issue. research on google. that will may help!
If the dash cam battery is 250mAh, and the battery pack is 20,000mAh, the the battery pack is like 80 dash cam batteries. So it should last 400 to 800 minutes. YMMV
