Snow Joe SJ620 vs SJ621: Which Electric Snow Thrower Should You Buy?

Clearing snow shouldn't require a chiropractor. The Snow Joe Ultra SJ620 and SJ621 are the top-selling electric single-stage throwers—but they're nearly identical. Here's the no-fluff comparison to decide if the SJ621's halogen light is worth the $30–40 premium.

Real-World Implications

• Morning/afternoon clearing: Light irrelevant. Save $30–40 → buy SJ620.
• Early morning/evening clearing: Light is genuinely useful for visibility and safety. If prices are close, get SJ621.
• Weight: SJ620 is 2 lbs lighter—slightly easier to maneuver and store.

User Ratings (Amazon)

• SJ620: 4.4/5 (88%) from 200+ reviews
• SJ621: 4.3/5 (86%) from 50+ reviews

Slight edge to SJ620, but both well-regarded.

Bottom Line

Buy the SJ620 unless you regularly clear snow in darkness and the price difference is <$15. The light is a convenience, not a performance upgrade. For larger areas (>2,500 sq ft), consider the SJ623E (21" width, 15 amp).

Either way, you're getting gas-like power without gas hassles—push-button start, no fuel, no pull cords, minimal maintenance. Your back will thank you.
