High-capacity 56800mAh power bank

This ViewSonic N9 power bank stores 56800mAh of lithium-ion energy for multi-day device charging. It delivers up to 22.5W fast charging through one bi-directional USB-C port and two USB-A ports. The black unit measures 7.0 in x 1.3 in x 3.4 in and includes an LED percentage display. It is not permitted on aircraft due to its capacity.

Check your device charging limits

Verify that your phone, tablet or earbuds accept 5V input at up to 3A for the fastest rates. The USB-C port handles both input and output, so confirm your wall charger can supply enough current to replenish the bank efficiently. Remember that airline regulations forbid carrying this capacity in carry-on or checked luggage.

Three-port simultaneous charging

The single USB-C and dual USB-A outputs let you power a phone, tablet and earbuds at the same time without extra adapters. Intelligent current adjustment protects each connected device from overvoltage and overheating. The built-in LED readout frees you from guessing remaining runtime during travel, camping or emergency backup situations.
