A 19-year-old from Florida developed the OffGrid Pro, a portable energy system with lithium iron phosphate batteries that keeps the fridge running for up to 3 days during blackouts, competes with the Tesla Powerwall for half the price, and can run indefinitely with solar panels.
When the power goes out during a hurricane, most people turn to flashlights or noisy, polluting gas generators. But a 19-year-old named Noah Bild from Palm Harbor, Florida, decided to build something better in his home garage. Over the past two years, he developed the OffGrid Pro, a portable energy storage system designed to keep homes running during blackouts without the noise, smoke, or health risks that traditional generators pose. The idea became urgent when last year’s hurricane season knocked out power in his own neighborhood.
What this 19-year-old built is not a school project. The OffGrid Pro uses lithium iron phosphate batteries, known for their stability and long lifespan, and is designed to compete directly with the Tesla Powerwall, offering similar features for about half the price. “Just with the portable charger, you can keep your fridge running for 2 to 3 days,” Bild explained to Fox 13 Tampa Bay. “And after connecting the solar panels, you can practically keep it running indefinitely.” For a region accustomed to hurricanes, it’s the kind of solution families have been waiting for.
How the 19-year-old moved from remote control cars to energy systems
Noah Bild’s journey to the OffGrid Pro began long before he turned 19. From an early age, he showed an inclination to build things, starting with remote control cars and advancing to electrical projects like unicycles, where he began experimenting with battery systems.

“Anything practical, anything electrical,” he told Fox 13. “I found the process of being able to generate power really cool.”
The leap from hobby to entrepreneurship happened when the 19-year-old realized that the technology he was using in personal projects could solve a real problem. The hurricane season exposed the vulnerability of his neighborhood, located near the water in Palm Harbor. “The power of many of our neighbors was interrupted.
Ours was too,” Bild reported. The personal experience with the blackout transformed a curiosity about electronics into a project with commercial potential that he spent two years developing in his home garage.
What is the OffGrid Pro and why does it compete with the Tesla Powerwall
The OffGrid Pro is a portable energy storage unit designed for residential use during emergencies.
The main advantage over traditional generators is that the system is completely silent, emits no smoke, and produces no odor, eliminating the risks of carbon monoxide poisoning that gas generators pose when used improperly indoors. For families that need power during hurricanes and are confined at home, this difference can be vital.
The 19-year-old designed the system to compete with the Tesla Powerwall in functionality, but at about half the price. Lithium iron phosphate (LiFePO4) batteries were chosen for their chemical stability, which reduces the risk of overheating, and for their durability, which allows for thousands of charge and discharge cycles before losing significant capacity.
The combination of portability, safety, and affordability positions the OffGrid Pro in a niche that Tesla serves with a more expensive and complex-to-install product.
The autonomy that keeps the fridge running for days and the solar panels that extend indefinitely
The autonomy numbers of the OffGrid Pro are practical and straightforward. With just the internal battery, the system can keep a fridge running for 2 to 3 full days, enough time for most storm-related blackouts to be resolved.
For those who have lost perishable food during a prolonged power outage, three days of autonomy represents a concrete financial difference.
When connected to solar panels, the OffGrid Pro can keep equipment running indefinitely, as the energy captured during the day recharges the batteries that power the home at night. This continuous cycle eliminates dependence on fossil fuel and transforms the system into a sustainable long-term solution, not just an emergency device.
The 19-year-old understood that the true utility of a portable energy system lies not only in the battery capacity but in the ability to continuously renew it with the sun.
The 19-year-old’s plans to expand the OffGrid Pro and build electric vehicles
Bild does not intend to stop at residential energy storage. He has already started showcasing the OffGrid Pro at local festivals in Florida and plans to expand the use of the system to support municipalities in emergency situations, where the need for reliable and safe energy is even greater than in individual homes.
The vision is for the OffGrid Pro to become a tool for community resilience, not just domestic.
In the long term, the 19-year-old intends to build his own line of electric vehicles, reinforcing his commitment to innovation in clean energy. Noah’s mother, Traci Bild, summed up her son’s potential to Fox 13: “This is just the beginning.
Anyone who supports Noah will be supporting the future of what we all might be using in 10 or 15 years.” For an entrepreneur who started with remote control cars and now competes with Tesla, the ambition seems proportional to the talent.
Why systems like the OffGrid Pro matter in a world of extreme weather events
The relevance of what this 19-year-old built goes beyond an inspiring garage story. Extreme weather events are becoming more frequent and intense, and each hurricane season in Florida, every heatwave that overloads the electrical grid, and every storm that knocks down transmission lines exposes the fragility of conventional energy infrastructure.
Families that rely solely on the electrical grid become vulnerable every time nature tests the limits of the system.
The OffGrid Pro represents a category of solution that returns control of energy back to the consumer. Silent, clean, portable, and compatible with solar panels, it offers autonomy at a time when energy independence has ceased to be a luxury and has become a necessity.
The 19-year-old who built all this in his garage may not have Tesla’s budget, but he has something that many large companies lack: a product that solves a real problem at a price that ordinary families can afford.

Stories like this show that innovation does not depend on billions in investment, but on someone willing to solve a problem that everyone faces.
