The phone that dies at hour three is the one running the whole block.
Verdict
Buy the car charger first, and only add a power bank if you walk a lot. A phone running navigation, the app, the camera and a bright screen can lose charge faster than a slow charger replaces it, which is why drivers still go flat with a cable plugged in. A proper 65W USB-C car charger fixes that. A power bank matters when you are away from the car for long stretches, which on apartment and downtown routes is most of the block.

You do apartment complexes, downtown routes or anything where you are out of the car for twenty minutes at a time. A 20,000mAh bank refills a phone several times and can live in a bag with a short cable. Its weakness is discipline: it only works if it went on charge last night, which is why it is the second purchase and not the first.

You want the fix that works without any habit change. A cheap five watt car adapter is why phones still die while plugged in, because it cannot keep up with the drain. A 65W USB-C Power Delivery charger both charges and gains ground while navigating, and it stays in the socket permanently so there is nothing to forget.

Because the charger is slower than the drain. Navigation, a bright screen and a delivery app can pull more power than an old USB-A adapter provides. Look for USB-C Power Delivery and a real wattage figure rather than a generic fast charge claim.
Considerably. A cheap or worn cable is a common reason a fast charger charges slowly, and it is the first thing to swap when the numbers do not match the box. Use a cable rated for the wattage you are trying to draw.
Around 20,000mAh is the practical ceiling for a bag. Larger units are heavy and some exceed airline limits, which matter if you travel. Check that it supports fast charging output, not just fast charging input.
