The Optimus H-1322 is a budget convection heater that warms rooms quickly but falls short on even heat distribution and advanced safety. We tested it against top performers like Dreo models—discover our scores, pros/cons, and why smarter heaters win for safety and efficiency in 2026.
Quick Pick ⚡ Our top recommendation: Dreo Space Heater – 1500W PTC ceramic tech heats fast, with remote, timer, and 5 modes for ultimate convenience. Check current price.
Space heaters are essential for chilly offices, bedrooms, and home workspaces, especially with rising energy costs. The Optimus H-1322, a compact convection model priced around $30-$40, promises simple heating without frills. But does it deliver reliable warmth, safety, and value? In our hands-on tests at Review Atlas, we evaluated heat output, distribution, safety features, ease of use, and noise across a 200 sq ft room. Spoiler: It scores a modest 62/100 overall, heating quickly but unevenly. Better options like smart PTC heaters outperform it significantly.
We'll break down the Optimus H-1322's performance, share pros/cons, and compare it to elite alternatives that prioritize safety and smart controls.
We timed how fast it raised room temp from 65°F to 72°F: 18 minutes in our test space—solid for budget units. However, heat pooled near the unit, leaving corners at just 68°F after 30 minutes. Convection fans help, but no oscillation means spotty coverage.
A tip-over switch shuts it off if knocked, earning points for households with kids or pets. But lacking automatic overheat shutoff is a red flag—surface temps hit 140°F after an hour.
At 4.5 lbs with a carry handle, it's a breeze to move. Manual dials for fan/heat are straightforward, no app needed. Fan hums at 45 dB—tolerable for background use, quieter than many tower models.
