EV research.
The Charge Port publishes original research on the U.S. electric-vehicle market — insurance costs, battery warranties, depreciation, solar payback, and 45 model profiles — with every number traceable to a cited source. Free to read, no account required.
Why We Built This
Most EV buying decisions come down to numbers that are genuinely hard to find: what a specific Model Y actually costs to insure in Michigan, how the Rivian R1T's battery warranty compares to the Mercedes EQS's, how much solar would offset your charging bill on your specific roof, whether a 2022 Bolt at $16,000 is a better used value than a 2023 Ioniq 5 at $32,000. The answers exist, but they're scattered across manufacturer warranty PDFs, state insurance filings, NREL weather data, and niche EV forums — and most of the sites that claim to have them are either wrong or a year out of date.
So The Charge Port is a project to put honest, up-to-date, source-cited answers in one place. We build the research tools we wished existed when we were shopping for our own EVs — and we keep the numbers current because pricing, incentives, and warranty terms change faster in the EV market than almost any other consumer category right now.
Everything is free to read. We support the site through affiliate partnerships (disclosed on each relevant page) and ads. Our editorial picks and rankings are made independently of any commission — if we say a product or model is best, it's because the data says so, not because the payout is bigger.
Editorial standards
Sources. Insurance data is derived from Insurance Information Institute tables, NAIC filings, Insurify and The Zebra state-rate reports. Warranty rankings come from current manufacturer warranty booklets (not dealer-quoted terms). Depreciation data is aggregated from used-market transaction prices. Incentive data is cross-referenced against official state and federal program pages. Every page that cites a number links back to the primary source where practical.
Freshness. Pricing and incentive data is reviewed at least quarterly; the Deals page is reviewed monthly. Each tool and article shows a "last updated" or "last verified" date so readers can judge freshness at a glance.
Corrections. Factual errors are corrected promptly with a dated note on the affected page. If you spot something wrong, the contact form is the fastest way to flag it.
Independence. No automaker, insurer, or service provider pays for placement in our rankings. Affiliate relationships are disclosed via sitewide footer plus per-page disclosures on the Gear and EV Insurance pages. See the Privacy Policy for the full list of advertising and affiliate partners.
