High-capacity power bank for extended off-grid use

This 56800mAh lithium-ion power bank supplies 5 volts at up to 3 amps through two USB-A ports and one two-way USB-C port. The black N9 model measures 7.0 in by 1.3 in by 3.4 in and delivers up to 22.5W output for compatible phones and tablets. It is built for multi-day charging during camping, travel, outdoor work or emergency backup.

Suited for users who need many recharge cycles

The pack can charge an iPhone 17 or Galaxy S25 more than ten times and reaches roughly 60 percent in about 40 minutes on supported devices. It is not suitable for anyone who must carry a power bank on commercial flights, as the capacity exceeds airline limits. Buyers who only need a single top-up for a daily commute should consider a smaller unit.

The 56800mAh capacity decides if this fits your

At 56800mAh the unit provides days of power for multiple devices but is explicitly not allowed on aeroplanes. If your travel includes air transport, this capacity makes the product unusable for that leg. For purely ground-based or stationary scenarios the same capacity is the feature that covers a full week of heavy phone and tablet use.

Questions about this item

Does the 56800 mAh battery get hot during 22.5W fast charging all day?

The 56800 mAh lithium-ion pack runs at 5 V and 3 A; the smart controller adjusts current to keep output stable and protect connected devices during extended use.

What cables do I need to use the USB-A and USB-C ports on this power bank?

The unit provides two USB-A outputs and one two-way USB-C port; bring your own USB-A to Lightning, USB-A to USB-C or USB-C to USB-C cables to match your devices.

Will the two USB-A ports still charge my older phone that only takes 5 V 1 A?

Yes, the smart power bank automatically adjusts current output so legacy 5 V 1 A phones charge safely alongside newer devices.
