With features like easy portability, fuel efficiency, and advanced safety mechanisms, portable generators have become indispensable for both everyday needs and emergency situations, making informed purchasing decisions crucial for consumers.

However, amidst a crowded marketplace filled with various brands and models, the importance of brand trust emerges as a decisive factor in consumer choices.

The 2025 America’s Most Trusted Study

What are the most trustworthy brands in America?  What companies do people see as trustworthy? What are the top brands people trust the most? 

The America’s Most Trusted® study has become a vital tool for brands seeking to grasp the nuances of consumer trust over its more than ten years of existence. This influential research reveals that the most successful brands recognize the profound impact trust has on consumer purchasing decisions, especially in a competitive market like portable generators. By benchmarking brand trust, the study provides invaluable insights, with updated results released each January, allowing brands to continually refine their strategies based on consumer perceptions.

For companies in the portable power generator sector, establishing and maintaining brand trust is critical for fostering repeat business. Trust is rooted in consumers' belief that a brand will deliver on its promises, which is particularly significant when they rely on generators during emergencies or outdoor activities. When consumers feel confident in a brand's reliability and performance, they are not only more inclined to make a purchase but are also likely to recommend that brand to others. This loyalty is especially crucial in the portable generator market, where trusted brands can significantly enhance customer retention and advocacy.

Conducted annually by Lifestory Research, the America’s Most Trusted® study involves over 75 product studies, surveying thousands of consumers about their experiences and perceptions of various brands, including those offering portable generators. At the core of this research is the validated Net Trust Quotient Score (NTQS), which assesses how consumers perceive trustworthiness in specific brands. This score serves as a powerful metric, indicating whether a brand meets or exceeds customer expectations compared to its competitors within the portable generator category. By employing rigorous social and opinion science research methodologies, the study delivers actionable insights that guide brands in cultivating trust and enhancing their market position.

  • What Is the America’s Most Trusted® Study?

    The America’s Most Trusted® study focuses on evaluating brands that offer products or services to consumers in their homes, particularly in the residential new home industry. Instead of attempting to survey every brand, the study specifically targets the largest and most impactful brands in this sector.

    How Does the Survey Work?

    Conducted throughout the year, the America’s Most Trusted® survey aims to gather consumer opinions while minimizing biases that might arise from external events or trends. This year-long approach helps capture a more accurate snapshot of consumer sentiments.

    Participants are surveyed based on specific criteria, such as whether they are actively considering a purchase in a relevant category—like buying a home, faucet, HVAC. Only those who express familiarity with a brand are invited to share their opinions on its trustworthiness, ensuring that the study reflects genuine consumer insights.

    The Importance of Brand Awareness

    An essential component of the study is brand awareness. Participants are first asked to identify brands they recognize. Only those who are familiar with a brand proceed to answer questions about it. This criterion ensures that only brands with sufficient public recognition are included in the final trust rankings.

    Sampling Methodology

    The study employs a non-probability sampling design, relying on online panels to recruit participants. Online panels are organizations that have an established relationship with consumers who agree to complete opinion surveys. Lifestory randomly ask consumers questions that identify consumers shopping for a specific product. Qualified consumers complete an online survey in which they are asked a set of questions about specific product brands.

    The number of people completing a survey is referred to as the sample size. Each of the America’s Most Trusted studies seek to obtain a sample size that is large enough to be representative. The sample size is also designed to collect a large number of consumer opinions to minimize error and to assure the study results reflect the majority of consumers sentiment about a brand.

    Calculating Trust Scores

    At the heart of the America’s Most Trusted® study is the Net Trust Quotient Score. Participants evaluate brands based on their trustworthiness through a series of targeted questions. The responses are then categorized into three groups:

    • Advocates: Consumers who express strong trust in the brand.

    • Neutrals: Those who trust the brand but do not consider it superior to others.

    • Antagonists: Consumers with little to no trust in the brand.

    These evaluations are quantified using a statistical method called a z-score, which standardizes the responses, allowing for easy comparison across brands. The results are ultimately transformed into T scores, which are more intuitive for understanding how each brand ranks relative to the mean score of all brands surveyed.

    Additional information about the study can be found on the survey methodology page of this website.
