Introduction
When the power grid fails as the result of unpredictable severe weather or aging infrastructure, the lights going out is no longer just a minor inconvenience — today, it can affect your work, spoil your food and cut off critical medical equipment. On the flip side, with the trend of wanting to be off-grid, outdoor enthusiasts want to take the comforts of the home deep into the wilderness.
The aim of this guide is to help you navigate the complex world of portable power generation. Whether you're searching for an emergency power source to maintain your home's central air during a blackout period or perhaps searching to have a cup of coffee brewed while at a remote campsite, this total guide will help you identify the very best power generator suitable for your wants.
How to Select the Right Generator?
Calculating Wattage Needs
Choosing the Right Generator Begins with Knowing Your Electrical Needs. Understanding your electrical demand is a guaranteed way to start your research.
- Running Watts (Continuous) — refers to the constant amount of power needed for continuing smooth operation of an appliance.
- Starting Watts (Peak) — the massive and short burst of energy that are often needed to overcome the inertia of motor driven components.
Brief Example: Charging a smartphone is a simple resistive load that barely requires a steady low amount of running watts. In contrast, for a refrigerator, there is a high surge in starting watts to engage the compressor and it settles down to a lower running wattage. To determine the size of your generator, of all items you wish to power, add all the running wattages, then add all the starting wattages from all listed units and find the single highest.
Traditional vs. Inverter Technology
| Feature | Conventional Generators | Inverter Generators |
|---|---|---|
| Engine Speed | Constant 3600 RPM | Auto-throttles to load |
| Power Quality | Standard AC | Clean AC (less than 3% THD) |
| Best For | Heavy-duty tools, large appliances | Sensitive electronics, medical equipment |
| Noise Level | Louder | Whisper-quiet |
| Fuel Efficiency | Lower | Higher |
| Size & Weight | Bulkier | Compact |
- Conventional Generators: These units have an engine which is operated at a constant speed of 3600 RPM for the maintenance of power frequency. Conventional models are best for raw power on a budget which makes them ideal for heavy duty tools and large appliances. However, they are louder, bulkier and less fuel efficient.
- Inverter Generators: These use microprocessors to convert AC power to DC, and then "invert" them back to AC power. Inverters are desperately required in order to obtain clean power, in the form of less than 3% Total Harmonic Distortion (THD) in order to safely power sensitive electronics, such as laptops and medical equipment without frying the microchip. They also automatically throttle their engine speed in response to the electrical load, the result of which is unbelievably quiet operation and very good fuel efficiency.
Fuel Types Explained
| Fuel Type | Key Strength | Key Weakness |
|---|---|---|
| Gasoline | Energy dense, widely available | Degrades rapidly, can gum up carburetors |
| Propane (LPG) | Burns cleaner, near-infinite shelf life | Slightly less raw power than gasoline |
| Dual / Tri-Fuel | Ultimate resilience, can run on natural gas line | Higher upfront cost |
| Battery / Solar | 100% emission free, silent, safe indoors | Must be recharged; limited by capacity |
- Gasoline: Most common fuel that is energy dense. However, it degrades rapidly and can gum up the carburetors if stored for too long.
- Propane (LPG): Burns cleaner than gas; almost infinite shelf life; ideal for emergency preparedness; generates slightly less raw power than gasoline.
- Dual/Tri-Fuel: Very ultimate resilience. A tri-fuel generator is a generator that can run using gas, propane fuel, or you can hook this up to your home gasoline line for a virtually unlimited run time.
- Battery/Solar Power Stations: These are 100% emission free, silent, and safe to use indoors. However, they must be recharged using wall sockets, vehicles or solar panels.
