Review of the Westinghouse iGen300S

Updated on: 29 November 2023 

– At A Glance –

Small and Light

Weighing just 6lbs and measuring 9.1L x 5W x 8.9H inches in size, this is a highly portable unit for a backpack.

Power to Size

300W continuous and 600W peak offer plenty of basic power for outdoors activities and home essentials.

Generous Outlets

Lots of power outlets so you can charge up to 9 devices simultaneously (within the unit’s rated power).

Eco-friendly power ideal for hikers and adventurers on foot

The robust eco-friendly and whisper-quiet iGen300s comes from a household name familiar to most, if not all, Americans. It provides you with 300W continuous and 600W peak power from its 296Wh rechargeable lithium-ion battery cell.

Weighing just 6lbs, it’s light weight makes it an ideal companion for camping, hiking, hunting, fishing, and all sorts of outdoor activities. It’s also equally useful to have on hand in the home, both as an emergency backup as well as for use where direct access to utility power is difficult without getting out long and potentially dangerous extension cords.

Maintenance-free, virtually silent and emission-free clean power

The iGen300s is a maintenance-free source of independent power, and with power station technology you won’t have any of the problems usually associated with portable generators, such as fuel storage, noise, and dangerous carbon monoxide fumes. The type of power output is Pure Sine Wave, similar to that provided by your utility company and won’t damage electronic components when charging delicate equipment.

While power station output levels cannot be compared with a gas or LPG-powered portable portable generator, it’s these other advantages that make a power station especially suitable for indoor use.

Control panel and LED display

Despite its diminutive size, the iGen300s is a fully featured device that also comes with an LED display to provide you with real-time information about wattage, charging status, and remaining battery life.

Multiple power outlets

There is a wide selection of outlets on the iGen300s, which include three USB ports (USB-C and Quick Charge 3.0), one 12V car cigarette socket, DC outputs, 12V DC input, and two 120V AC household outlets. With these you can charge/power:

  • Up to 9 devices simultaneously
  • Up to 40 hours of lights
  • 3 hours of TV
  • 14 smartphone charges
  • 3 laptop charges
  • 6 drone charges
  • 2 nights on select CPAP devices

Built-in powerful lighting system

A built-in Tri-Mode flashlight provides you with bright light whenever you need it, in your home during an outage, or out on the trail as it gets dark.

Charging the iGen300s

Charging the unit is easy, using an AC outlet, your car’s 12V lighter socket, or with an optional eco-friendly solar panel fitted with an 8mm output plug and no more than 19V. Connected to a household outlet the unit charges to 80% in 5 hours, and between 5 and 7 hours using the car adapter or a solar panel.


Westinghouse back this product with a 2-year warranty and limited service, labor, and parts coverage. They also have Nationwide Customer Service Network should you need it. 


A bright LED display is built into the iGen300s so you can know constantly the operational situation and status of the power station.

Power Outlets

An excellent set of power outlets is provided so you can charge/power up to 9 devices at the same time (within the overall 300W limit).

Recharging Methods

Diverse methods of recharging on this model. An AC charger and car adapter are included in the box but a solar panel such as the Westinghouse WSolar100p (paid link) is seen as an essential optional accessory to get the most out of the unit. And it can also be charged if and when your portable generator is running.
