Guaranteed cost savings

powerbox

Case Study: PowerBox charged overnight using grid electricity, providing clean, quiet energy for your food truck. More savings with optional solar package.


The Cost & Impact: The PowerBox can last for 10 yrs with proper maintenance. Leading to an approx. cost of ownership every 10 yrs at $10,860.00


- Energy Expense: Charging a PowerBox with 10KWh capacity overnight from the grid costs about $1.50 per full charge (based on the national average electricity rate of $0.15 per kWh).

- Annual Cost: For 224 days of operation, the annual energy cost is only $336.00, significantly lower than the cost of gasoline.

- Initial cost to purchase $7500.00.

- Maintenance Savings: The PowerBox requires minimal maintenance compared to gas generators, further reducing annual costs.

- Enhanced Customer Experience: With no noise or fumes, your customers can enjoy a more pleasant dining experience, drawing more patrons to your food truck. 

Traditional Gas Generator Setup

Case Study: A typical food truck powered by a gas generator, running for 12 hours a day.


The Cost & Impact: Gas Generators can last for 4 yrs with proper maintenance. Leading to an approx. cost of ownership every 4 yrs at  $20,089.60 


 - Fuel Expense: Gas fuel costs average $3.50 per gallon, and a standard generator consumes about .15 gallons per hour. That’s 1.8 gallons daily, totaling around $6.30 in fuel costs per day.

 - Annual Cost: If you operate 224 days a year, that adds up to $1411.20 annually, just on fuel.

- Maintenance Hassle: Gas generators require frequent maintenance, adding another $800 per year in servicing.

- Initial cost to purchase $1200.00.

- Environmental Impact: Gas generators emit harmful noise and fumes, contributing to air and noise pollution, minimizing the customer’s experience.
