You definitely don't want to take chances if your car battery is old and/or your car sits still for days on end at an airport carpark with your dash cam in parking mode slowly draining your car battery.

When looking for a jump starter, a solution such as Aukey's PB-C2 is great because it can provide 400 cold cranking amps (CCA) and it's small enough to carry and store in the glove compartment of the car.

Aukey's PB-C2 400 amp jump starter keeps the charge when sitting idle even for long, thanks to the battery being lithium-ion based rather than lead acid which tends to self discharge and lose cold cranking amps when sitting idle for too long.

By the way, the term "Cold Cranking" refers to how long it takes to turn over or start a car engine in cold weather, while Amps refers to current delivered while cranking the engine. Therefore, Cranking Amps (CA) means how long you can keep cracking a car engine while the car battery can deliver X amount of amps while holding voltage above 7 volts.
It's never a good idea to keep cracking an engine for minutes on end because the longer you keep cranking an engine, chances are that you will drain the battery. This is why a jump starter or car battery that can hold voltage well is very important because in order for a battery to deliver 300 Cranking Amps it needs a steady voltage above 7 volts.
The 15V/1A input allows you to recharge the battery via power wall adapter and car cigarette lighter adapter. Both of these are included. As far as charging the 12,000mAh built-in powerbank, it takes around 5 hours to fully charge from flat.
