I want to get myself a power bank for when i travel around. The only devices i would need it for would be my iphone, steam deck, headphones and speaker. I want something that lasts a long time and charges decently fast but also not something too huge but i’m open to any advice or recommendations. I’m not huge into my tech so don’t really know what all the specifications mean. Anyone got any good recommendations for my needs?
