Best Home Electric Vehicle (“EV”) Chargers in 2025: The Osta Step-by-Step Guide to Choosing an EV Charger and Understanding Installation Costs.

The Osta Step-by-Step Guide to Choosing an EV Charger and Understanding Installation Costs.

 February 20, 2025

When choosing an EV Charger for your home, it’s essential to compare charging speeds, pricing, and EV compatibility. 


Step 1: Understanding The Difference Between EV Charger Types (Level 1 vs. Level 2)

There’s two types of EV Chargers: Level 1 and Level 2

Level 1 chargers use a standard 120V¹ outlet and are best for plug-in hybrids such as Toyota Prius Prime or Honda Clarity Plug-in Hybrid, or low-mileage drivers due to their slower charging speeds. Alternatively, Level 2 chargers run on a 240V circuit, making them better for daily EV drivers who need faster overnight charging. The table below summarizes the key differences:

Step 2: Key Features to Look for in an EV Charger

The must-have features in an EV Charger in 2025 are 1) charging speed, 2) smart connectivity, 3) durability, 4) universal compatibility, and 5) warranty.

1. Permit Fees: Typically $200-$500, depending on the city.

2. Labor: Around $500-$1,500, impacted by distance to the main panel and installation complexity.

3. Charger Unit: Usually $400-$1,200, depending on the Level 2 charger model selected.

4. Panel Upgrades (if required): Adds approximately $1,500-$3,000 if an upgrade is necessary for load handling. 

The EV charger installation cost breakdown shows that total expenses generally range from $1,100 to $6,200, depending on factors like labor, permits, and panel upgrades.

Good News: Many local utilities offer rebates & tax credits to lower the cost.¹⁷

EV Growth Trends – Why Home Charging Matters More Than Ever

Electric vehicle adoption is skyrocketing, and home charging is becoming a must-have for new EV owners.

  • In 2024, U.S. EV sales reached a record 1.3 million units, accounting for 8.7% of all new car sales (Kelley Blue Book, 2025).

  • Projections for 2025 estimate that EVs will constitute 13.5% of new light-vehicle sales in the U.S (Investing News, 2025).

  • Looking ahead, forecasts suggest that by 2030, annual EV sales in the U.S. could reach 7.7 million, representing nearly 46% of total light-duty vehicle sales (Edison Electric Institute [EEI], 2025).

  1. Voltage (“V”) is the measure of electrical potential difference between two points in a circuit, determining the force that drives electric current. Higher voltage allows for faster power transfer, which is why Level 2 EV chargers (“240V”) charge significantly faster than Level 1 chargers (“120V”). Autel Energy. (n.d.).
