EV Charger Buying Checklist: Everything to Compare Before You Purchase 

India registered 2,452,921 electric vehicles in FY2026, a 25% jump over the previous year across scooters, autos, and cars, according to Autocar Professional’s analysis of the year’s sales data.  

Each one of those buyers eventually faces the same question: how to choose an EV charger. Should it be AC or DC? What power rating works best? Can the home’s electrical load support it? And are smart features worth the extra cost?  

This EV charger buying guide breaks down the decision into one straightforward checklist: charger types, power ratings, installation requirements, certifications, smart features, and cost. 

AC vs DC Chargers: Which One Do You Actually Need? 

• How AC and DC Chargers Actually Differ 

AC chargers send alternating current to your car, which the vehicle’s onboard charger converts into direct current before it reaches the battery. DC chargers skip that step, converting the power themselves and sending direct current straight to the battery. This is what makes DC chargers faster but also requires thicker cables and three-phase power. 

In India, almost every home AC charger for four-wheelers uses the Type 2 connector (IEC 62196-2), including Bolt.Earth’s Blaze AC. For 2- and 3-wheelers, AC charging typically runs through the bundled charger. DC fast charging uses different connectors depending on the brand. 

• Which Type Suits Different EV Owners 

Your parking pattern decides more than your budget. Vehicles parked overnight or through the workday suit AC chargers, cheaper to buy and install. A quick top-up between short stops, like a 2-wheeler rider on a delivery run, suits DC fast charging instead. A private car charging overnight rarely needs DC speed; that’s a cost businesses and high-turnover sites take on, not homes. Our guide to setting up EV charging infrastructure covers that scale. 

For 2-wheelers, your connector standard, Type 6, Type 7, or a brand’s own proprietary port, decides which fast chargers physically fit your scooter before power rating even matters. 

• Power Ratings: How Fast Different Chargers Actually Charge 

A higher kW rating only helps if your vehicle can actually use it. 

• Check Your EV’s Onboard Charging Limit First 

Every EV has its own onboard charging limit. A charger rated higher won’t charge faster if your EV’s onboard charger caps the draw. For example, a base Tata Nexon EV or Punch EV at 3.3kW takes 10-15 and 9-10 hours, respectively, for a full charge, while variants built for 7.2kW input, like the Nexon EV Max, Tiago EV, and MG ZS EV, cut that to about 5-6.5 hours, as per ev.care’s comparison. Check your spec sheet for maximum AC input before paying for power your car can’t use. 

Electrical Load and Safety Certifications to Check 

• Does Your Home’s Sanctioned Load Support It? 

Your home’s sanctioned load, the maximum power your connection is approved to draw, decides which charger you can install. A typical Indian 2BHK runs a 3-5kW single-phase load. A 3.3kW charger comfortably within a 5kW connection, while a 7.4kW charger almost always requires a higher sanction or three-phase power. These are industry guides, not government figures, so confirm your own load from your bill first. 

If you live in an apartment, add your society’s written approval to the checklist, since parking is a common property. India’s Model Building Bye-Laws (MoHUA, 2019) require at least 20% of new-building parking to be EV-ready, but RWA sign-off is still essential. Our budget EV charging setup guide covers this and the full cost math. 

• Safety Certifications and Professional Installation 

Every EV charger sold in India needs BIS certification under IS 17017, covering shock, fire, and overcharging protection. ARAI certification under AIS-138 isn’t legally required but adds tested assurance.

Installation matters as much as certification. A charger without a dedicated circuit or proper earthing, or one installed by someone unqualified, wastes that certification. Bolt.Earth’s Blaze AC includes installation in its price (wiring from the meter is billed separately). Read Blaze AC unboxing guide for what that looks like. 

Smart Features: What They Add, and What They Don’t 

• Scheduling, Monitoring, and App Integration 

Smart chargers connect over Wi-Fi or 4G and show live charging status and energy used through the Bolt.Earth EV Charging App, useful since it saves you from guessing whether charging started. 

• Why Smart Chargers Add Long-term Value 

A smart charger’s value comes from its capability to track energy use, catch a fault like a voltage spike early, and, if need be, list spare capacity for other EV owners. A plain socket charger might not be connected to any app, so none of that information shows anywhere.  

A smart charger is worth the set-up cost for most first-time buyers, though it’s a preference, not a safety requirement; a certified basic charger is just as safe when installed correctly. 

The Buyer’s Checklist: Cost, Comparison, and Next Steps 

Use the checklist below to compare your shortlist side by side. 

• Comparing Upfront Cost vs. Lifetime Savings 

The charger’s price tag is rarely the full cost. Bolt.Earth’s Lite (₹4,999) and Pro (₹5,499) smart sockets add monitoring over standard 3.3kW charging, not speed, just visibility. Blaze AC 7.4kW currently costs ₹24,999 and includes installation but not wiring. A fully installed system runs roughly ₹18,000-35,000 for 3.3kW and ₹35,000-80,000 for 7.4kW, plus ₹15,000-40,000 for a three-phase upgrade, as per ev.care’s cost breakdown. 

Use this home EV charger comparison as your starting point, then narrow it by your sanctioned load, onboard limit, and daily distance. 

How to Use Bolt.Earth’s Charger Recommendation for Personalized Guidance 

Bolt.Earth’s Set Up Your Charger tool takes the three answers this checklist just walked you through, connector, sanctioned load, and charging speed need, and turns them into a specific match. Enter your use case, available power, and vehicle, and it recommends a Bolt.Earth charger and software plan sized to your site, complete with pricing.  

Final Thoughts 

Buying an EV charger is a long-term investment and eventually comes down to matching four things: your connector, your onboard limit, your electrical load, and a certification. Get those right, and the choice between a ₹5,000 socket and a ₹24,999 smart AC charger becomes convenience, not compatibility. Run through this EV charger buying checklist once, and you’ll spend less time comparing specs and more time charging.
