Multi-day capacity for travel and emergencies

The N9 power bank stores 56800 mAh of lithium-ion energy, enough to recharge a typical smartphone more than 10 times. It supports iPhone 13 through 17 series, Samsung Galaxy S23 through S25, Google Pixel 7 through 9, tablets, earbuds and other USB devices. The unit is not permitted on aircraft because its capacity exceeds airline limits.

22.5W output with triple-port charging

A two-way USB-C port and two USB-A ports deliver up to 22.5 W combined, allowing three devices to charge simultaneously. The controller adjusts current automatically for stable output and device protection. An iPhone 17 reaches roughly 60 percent charge in about 40 minutes from the USB-C port.

Compact black chassis with LED status display

The housing measures 7.0 in by 1.3 in by 3.4 in and weighs little enough for a backpack or glove compartment. A built-in LED display shows remaining capacity at a glance. Three output ports and one input port cover daily charging routines without extra cables or adapters.

Questions about this item

How do I start charging my phone with the USB-C port on the N9 56800mAh power bank?

Connect your device to the two-way USB-C port using a compatible cable; the power bank automatically detects the connection and begins delivering up to 22.5W without any button press.

What long-term care does the lithium-ion battery inside the N9 56800mAh power bank require?

Recharge the unit at least every three months during storage to prevent deep discharge, and avoid leaving it fully depleted for extended periods to preserve the 56800mAh capacity.

At what point does the 22.5W fast-charging rate drop during a continuous charging session?

The 22.5W output is maintained while the internal cells have sufficient voltage; once the power bank's own charge falls low, the output current automatically reduces to protect the battery.
