Sun Joe MJ403E Mow Joe 17-Inch 13-Amp El vs AMERISUN 14-Inch 2IN1 Electric Lawn Mowe
Quick Verdict
The Sun Joe MJ403E is the stronger overall choice for most homeowners. It offers a wider cutting deck, more power, and a mulching function, backed by a much larger sample of user reviews. The AMERISUN 14-inch is a budget-friendly option for very small yards where low cost is the top priority, but it compromises on width, features, and reliability.

Where Sun Joe Wins
Wider cutting deck. The 17-inch width cuts a noticeably larger path than the 14-inch AMERISUN. This means fewer passes and less time mowing, especially on an open lawn.
More power. At 13 amps, the Sun Joe has a slight edge over the 12.5-amp AMERISUN. This helps it handle thicker grass and light weeds without bogging down.
Mulching capability. The Sun Joe is specifically listed as a mower/mulcher, which means it can finely chop clippings and return nutrients to the lawn. The AMERISUN is a 2-in-1, likely offering only bagging and side discharge—no true mulching.
Much higher user confidence. With over 1,200 reviews and a 4.0 average, the Sun Joe has a proven track record. The AMERISUN has only 90 reviews and a lower 3.6 rating, suggesting more variability in quality or satisfaction.
Better build and brand reputation. Sun Joe is a well-known brand in electric outdoor tools, with readily available parts and customer support. AMERISUN is a lesser-known brand, which may mean less reliable service.
Where AMERISUN Wins
Price. At $120.51, the AMERISUN is nearly half the cost of the Sun Joe. For someone on a very tight budget who only needs to mow a tiny patch of grass, this price difference is significant.
Lighter weight. The 14-inch deck and lower amp motor likely make the AMERISUN lighter and easier to maneuver in tight spaces, such as around flower beds or garden edges.
Lower blade speed may be quieter. The 3400 RPM specification suggests the motor spins slower than many 13-amp mowers, which could translate to slightly less noise during operation.
Adequate for tiny yards. For a yard smaller than 1,000 square feet, the narrower deck and lower power may be sufficient, and the low cost makes it a disposable option.
Which Should You Buy
Buy the Sun Joe MJ403E if: You want a reliable, capable electric mower for a small to medium lawn. The wider deck, mulching feature, and proven user reviews make it a better long-term investment. It handles typical suburban lawns with ease and offers better value per square foot cut.
Buy the AMERISUN 14-inch if: Your absolute maximum budget is around $120 and your yard is very small—perhaps a tiny city lot or a small patch of grass. You are willing to accept a narrower cut, fewer features, and less reliable performance to save money. It is best for occasional use on easy, thin
