You need charger (or battery bank) with the appropriate USB PD version. Most cheap phone charger do not talk USB PD - but - you could get one of those and it should work with everything.
USB PD 2 or 3 typically come as 45W or more. 60W ones are pretty small and you could charge laptop, phone, battery bank off it. Framework sells one of the GaN small 60W types for reasonable $$. Or bring your 100W laptop brick for free to charge your phone fast.
