Massive capacity in a compact form

The ViewSonic N14 power bank stores 50000 milliamp-hours of energy while measuring only 4.8 by 3.1 by 1.1 inches and weighing 0.75 pounds. Its lithium-ion cells deliver 192.5 watt-hours at 3.85 volts, and the unit is 30 percent smaller and 15 percent lighter than traditional high-capacity models. Built-in cables and a smart LED display make it a self-contained solution for extended off-grid use.

Ideal for multi-device travellers.

Users who need to keep a phone, tablet, earbuds, and smartwatch powered for days will appreciate the five simultaneous outputs and four integrated cables. The 22.5-watt fast charging brings an iPhone 17 to 55 percent in 30 minutes and a Galaxy S25 to 60 percent in the same window. Buyers who only top up a single handset overnight may find the capacity and cable bundle excessive for their needs.

Fits in a pocket, replaces a cable bag

Four built-in cables — Micro-B output, USB-A input, Type-C output, and Lightning output — plus three extra ports (Micro-B input, Type-C input/output, USB-A output) eliminate the need to carry separate cords. The 90-minute recharge time restores the bank quickly between trips. Over-charge and short-circuit protection safeguard connected gear, while the digital percentage display lets you plan remaining power at a glance.

Questions about this item

What devices must I already have to charge this power bank?

You need a charger with a USB Type-A or USB Type-C port and a matching cable to supply up to 3 A at 5 V.

Will my older phone that only takes Micro-USB still charge from the built-in Micro-B cable?

Yes, the integrated Micro-B output cable delivers power to any device with a Micro-USB port, up to the bank's 22.5 W limit.

How do I confirm the power bank is charging my devices at the advertised fast rate?

The LED digital display shows the exact remaining percentage; watch it drop steadily while your phone reports fast charging.
