Can your electrical panel support an EV charger? Find out in minutes with a real NEC load calculation -- no electrician visit needed. ChargeRight gives homeowners clear, code-based answers about their panel capacity before committing to expensive electrical work. Built by a Master Electrician, not a tech company or an installation broker. HOW IT WORKS 1. Photograph your panel -- open the door so the breakers are visible. 2. Answer questions about your home -- panel size, square footage, heating, and the appliances you already run. 3. Pick your EV -- the circuit is sized to the driving you actually do, not to the biggest charger an installer can sell you. 4. Get your report ($69.99) -- your load calculation, your panel's spare capacity, and what to tell your electrician. WHAT YOU GET • A real NEC load calculation, the same math a licensed electrician runs before quoting you • AI analysis of your panel photo for visible safety concerns • Your calculated load, your panel's safe capacity, and the headroom left over • A charger size matched to your driving • A word-for-word script for the call with your electrician • A shareable report link you can open from any browser WHY IT MATTERS J.D. Power found only 28% of EV owners needed panel-specific work, even though ESFI found 65% were told they did. A proper load calculation can save you $2,000-$4,500 by avoiding an upgrade you do not need. Don't accept "you need an upgrade" without seeing the math. BUILT BY AN ELECTRICIAN, FOR HOMEOWNERS ChargeRight was founded by Jason Walls, a Master Electrician with EVITP certification. There is no financial incentive to upsell you here. The only job is giving you accurate numbers. • Independent -- nothing is installed and no installation is brokered • Code-based -- calculations follow the National Electrical Code • Private -- your data is used only for your report $69.99 per assessment. One time, no subscription. This is a pre-assessment, not an official inspection or a permit. Have a licensed electrician confirm before any work.
