Looking for the best Level 2 EV charger? We compare top options from Tesla, ChargePoint, Emporia, Wallbox, Grizzl-E, Autel, EVIQO, and Lectron. From dual-standard connector flexibility and dynamic load management to rugged plug-and-play simplicity, find the right fit for your home charging setup.
The Emporia Pro bundles genuine whole-home load management and a free Vue 3 energy monitor into a $599 charger, making it the smart pick for older panels and solar homes — minor hardware gripes aside.

The ChargePoint Home Flex is one of the most adaptable home EV chargers you can buy, with amperage you can dial from 16A to 50A, a choice of J1772 or NACS connectors and genuinely useful scheduling. A premium price, modest NEMA 3R weatherproofing and no native load sharing keep it from a clean sweep.

The Pulsar Plus 48A packs 11.5 kW, a 25-foot cable and a genuinely useful app into one of the smallest Level 2 boxes you can hang on a wall — but the hardwire-only install and stiffer cable mean most drivers should buy the 40A version instead.

Autel's plug-in Level 2 charger pairs a genuinely long 25-foot cable and weatherproof build with a polished app and load-balancing smarts, making it an easy recommendation for most home EV owners — if you can pin down its wildly inconsistent price.
A deliberately dumb, extremely tough 40-amp home EV charger that nails the basics for $299.99 — the right buy if you want charging hardware you never have to think about, and the wrong one if you want scheduling, monitoring or app control.
EVIQO's 48A Level 2 charger hits all the marks that matter for home charging — 11.5 kW output, UL/Energy Star certification, a long 25 ft cable and genuinely useful scheduling in the app. Without confirmed pricing it's hard to call it a bargain, but on paper it's a well-rounded, well-protected choice.
Lectron's portable Level 2 charger nails the budget brief: 40 amps, WiFi you can ignore, a carrying case and roughly 8 pounds of travel weight for around $230. The short 16-foot cable and the missing UL/ETL listing on the older model keep it out of top-tier territory.

Tesla's dual-standard Level 2 charger handles both NACS and J1772 cars from one 48-amp unit, with an integrated adapter that can't go missing. At $580 it's a premium buy, but for two-car households split across standards it's the tidiest answer going.
The Boston startup has closed a $15 million Series A2 led by New Zealand's AgriZeroNZ, with support from Breakthrough Energy — while cutting roughly a third of its staff to focus on a single market, a single product and its first revenues.
