Portable 15000mAh Charger

The HELLEE N18 is a 15000mAh lithium polymer power bank rated at 22.5W output. It targets travellers and commuters who want a single unit that can recharge a phone several times without carrying separate cables.

Airline-Safe 22.5W Output

The 15000mAh capacity sits under the 100Wh limit, so it meets TSA carry-on rules. Maximum output is 22.5W through the USB-C port; actual usable energy is typically 60–70% of the rated capacity, or roughly 9000–10500mAh, because of conversion losses.

Check Your Devices and Charger

Verify that your devices charge via USB-C, Lightning, Micro-USB or USB-A, the four built-in connectors supplied. To recharge the power bank itself you need a USB-C wall charger; a 27W adapter refills it in about three hours, while a 15W adapter takes roughly four hours.
