Questions about this item

What cables come built into the HELLEE N18 and do I need to buy any extra?

The power bank has four built-in cables — USB-A, USB-C, iOS and Micro-USB — plus a separate USB-C to USB-C cable in the box, so most devices can charge without buying anything else.

Which capacity should I choose for an iPhone 17 and how many full charges will it give?

The 15000mAh model delivers up to 3.5 full charges for an iPhone 17, 2.5 charges for a Samsung S26+ and around 20 charges for AirPods Pro.

What does the 22.5W rating mean when I plug my phone in?

It means the bank can push your phone to roughly 50% battery in 30 minutes, and a 27W wall charger will refill the bank itself in about 3 hours.
