I'm going to travel to the Algarve in September and I want a power bank that lasts a long time and isn't too heavy to carry in my backpack. I have two phones and a tablet to charge. What capacity do I need?
With two phones and a tablet you're gonna need something with pretty decent capacity, I'd say at least 20000 to 25000 mAh, otherwise you'll run short! I've been using an Anker 20000 mAh for years and I don't regret it, it's solid and not too heavy for the backpack. If you want something more compact and lightweight, there are 15000 mAh options that work fine, but then you can only give all your devices a full charge once or twice. Also pay attention to the number of USB ports, because with three devices you might want to charge more than one at the same time and it's way more practical!
