Portable Power Station vs Inverter Generator for Home Backup

For most things in life, we have backup plans and contingencies in case something goes wrong. Why not for a power outage?

Two options for dealing with power outages are: portable power stations and inverter generators. While both provide electricity during outages, they differ in their suitability for various scenarios.

Let's delve into their key differences to help you decide which is right for your needs.

Portable Power Stations:

These compact units contain a lithium battery and inverter enclosed within a durable casing. Portable power stations work electronically and are suitable for indoor use, unlike traditional generators, and have multiple output ports.


  • No Emissions: A portable power station offers clean lithium-ion energy, making them ideal for indoors. This sets them apart from conventional fuel-powered generators, which cannot be used in enclosed spaces.

  • Versatility: Portable power stations come in various sizes and power levels for your unique needs, from smaller units capable of charging phones and laptops to larger ones that can power multiple appliances simultaneously. They can also handle sensitive electronics, which can be plugged directly into the tower.

  • Compact Size: While this may vary depending on the model, portable power stations are typically the lighter and smaller option for off-grid power.

  • Rechargeable: Running on lithium batteries, portable power stations can be quickly recharged using various methods (wall charging, solar panels, or 12v car charging). These units can also hold stored energy for months at a time when not in use.

  • Quiet Operation: The unit's electrical power is quiet and unobtrusive in your home, caravan or wherever you need it.


  • Cannot generate its own power supply: Unlike fuel-powered inverter generators, which can run continuously if adequately fuelled, a portable power station does not generate electricity. It acts more like a giant battery and will eventually need to be recharged after use.

  • Initial cost may be higher: Comparatively, these units often have a larger buy-in cost. However, they are renewable power sources and you will not need to buy fuel to run them over time.

iTechworld's range of power stations: iTechworld offers a large selection of portable power stations, including the PS3600 PRO, PS2000, and PS1300, each designed to meet specific needs.

Inverter Generators:

iTechworld's new Redback inverter gensets

Inverter generators are newer petrol-powered devices that generate electrical energy through the combustion of fuel. These powerful portable generators are particularly useful for outdoor settings where access to electricity may be limited.


  • Petrol-Powered Reliability: Inverter generators do not require charging and can provide continuous power as long as they are fuelled.

  • Cleaner Energy: Compared to conventional fuel generators, inverter technology uses a cleaner conversion process and produces a higher quality electrical output which can better handle various sensitive electronic devices (unlike conventional generators).

  • Quieter Operation: Inverter generators produce much less noise than their traditional fuel counterparts, offering a minimal-noise option even at full use.

  • High Fuel Efficiency: Another bonus to inverters over traditional generators is that they are highly fuel efficient, producing a greater power output suitable for powering multiple devices simultaneously.


  • Cannot be used indoors: Inverter generators should never be run indoors. They must be used outside in a well-ventilated area, as their internal combustion engines release toxic emissions which will be harmful in enclosed areas.

iTechworld's range of inverter generators: Our Redback RB4.5 and Redback RB3.5 generators are prime examples of powerful options available in the market. With output capacity ranging from 3500W to 4500W, these generators make a substantial power source for various applications. Click the following link to shop our inverter generators.

Which is Better: an Inverter Generator, or a Portable Power Station?

Both inverter generators and portable power stations have merit, and ultimately your intended usage will define which is more suitable for your backup power requirements.

For indoor use to store energy, or to have a reliable power source in case of an outage, a portable power station will be perfect. Our pick, the PS3600 PRO, is suitable for portable off-grid use (e.g. caravans) or as a home backup system. It also has solar panels for true off-the-beaten-track charging capabilities.

For use in an outdoor area where continuous power is needed, an efficient inverter generator system such as the Redback RB4.5 will perform admirably. As long as you have fuel, you can continuously power devices and appliances. This is perfect for camping, caravans, or sheds. They can go almost anywhere, but you cannot use them indoors or in an enclosed space.

Don't Get Caught Without Power

Being prepared can make all the difference when the power grid goes down. Without a backup supply to provide power, you risk food wastage, discomfort, or even failure of medical devices. iTechworld offers a range of options to suit your specific needs - don't wait until the next power cut to get yours.
