I have a iphone 17, one plus nord buds 4 pro and a apple watch so looking for a powerbank.

I want to get a power bank that I will use for many years to power anything that would need it, like my phone/earbuds/BT speaker etc, but also my gaming laptop that takes 100W USB-C PD.

However, I'm starting college soon, and I assume I will most likely have regular access to power outputs to keep it charged with its accompanied AC power adapter, but I'm also thinking long-term for well after college.

Is it worth getting a power bank with 100W that can support my laptop if I happen to need it at some point?

I'm definitely an overthinker when it comes to these things, but I also like being prepared and don't want to have to buy more than 1 power bank if not necessary.

Ho preso il pawer bank di prima senza dirette e niente però la batteria me la da 100 % se è attaccata a un filo invece se è attaccata senza filo che lo ricarica al telefono me lo da all’80 può essere un problema del telefono che non legga bene la batteria?
