Introduction

Deerma (德尔玛) is a Xiaomi ecosystem company that specializes in household cleaning and garment care products. The DEM-STS300 is their entry-level portable steam iron, designed for quick wrinkle removal rather than heavy-duty ironing. It bridges the gap between a traditional iron and a garment steamer.

On JD.com at ¥119 ($16), the STS300 competes with the Midea handheld steamer (¥99) and the Xiaomi garment steamer (¥149). Deerma’s 50,000+ reviews suggest strong market acceptance for this budget-friendly approach to garment care.

Design and Build Quality

The STS300 features a compact design with a foldable handle that collapses flat for storage. The ceramic soleplate has a pointed tip for reaching into button areas and seams. The transparent water tank on the back shows water level clearly.

At 600g, it’s light enough for one-handed operation without fatigue. The handle has a comfortable grip with a steam trigger button on the top — press for steam, release to stop. This gives good control over steam output.

The 1.8m power cord is reasonable but not generous. The water tank uses a simple silicone fill hole — pour water directly, no funnel needed. The lack of auto shut-off is a safety omission at this price point.

“出差旅行神器！折叠起来不占行李箱空间。这个价格效果完全超出预期。热得很快，25秒就能用。烫衬衫和T恤效果不错，蒸汽量够用但不算大。缺点就是水箱太小，烫一件衬衫要加一次水。” — JD.com verified buyer, 200+ votes “Essential for travel! Folds flat and doesn’t take luggage space. Results far exceed expectations at this price. Heats up fast — 25 seconds ready. Good for shirts and t-shirts, steam volume is adequate but not large. Downside is the small tank — need to refill for one shirt.”

Performance

The 1200W heating element brings the iron to operating temperature in 25 seconds — genuinely fast. The 15 g/min steam rate is modest but sufficient for light-to-medium wrinkles. For heavy creases, you’ll need multiple passes and may need to pre-wet stubborn areas.

Steam performance:

• Light cotton shirts: 1-2 passes for wrinkle removal
• Polyester blends: 1 pass, excellent results
• Heavy linen/cotton: 3-4 passes, needs water spray assist
• Denim: Limited effect, steam output is insufficient

The ceramic soleplate glides well without sticking. The pointed tip allows working around buttons. Dry ironing works adequately for crisper results on cotton.

Battery: N/A (corded). The 1200W power limits it to Chinese 220V households. Not suitable for 110V regions without a transformer.

What Chinese Users Say

“租房子没有熨衣板，这个正好。放在桌上或者床上就能用，折叠起来随便塞柜子里。烫得快，25秒就好了，早上出门烫一下很节省时间。119性价比很高。但蒸汽确实不够强，厚衣服不好烫。” — JD.com verified buyer, 150+ votes “Don’t have an ironing board in my rental. This works on a table or bed. Folds away easily. Heats up fast in 25 seconds — great for quick touch-ups before going out. Excellent value at ¥119. But steam is not strong enough for thick clothes.”

“和之前买的美的一款对比，德尔玛的蒸汽量更大一些，预热也更快。折叠把手很方便，塞抽屉里不占地方。水壶容量确实小，两件衬衫要加两次水。适合单身或两人家庭使用。” — JD verified buyer “Compared to the Midea one I bought before, Deerma has stronger steam and faster preheat. Foldable handle is convenient for drawer storage. Tank is small — need two refills for two shirts. Suitable for single person or couple households.”

“买来给学生宿舍用的，功率够用不会跳闸。简单烫校服和日常衣服完全够了。性价比高，推荐给预算有限的朋友。需要注意这个不能用于110V电压，出国不能用。” — JD.com verified buyer “Bought for dormitory use, power is low enough not to trip breakers. Fine for school uniforms and daily clothes. Great value, recommend for budget-conscious buyers. Note: 220V only, doesn’t work on 110V.”

Purchase Recommendations

✅ Worth Buying (¥119)

Best budget portable steam iron for quick touch-ups, travel, and small households. The foldable design and fast heat-up are genuinely useful.

💰 Premium Pick

At ¥249, the Philips STH3000 offers stronger steam (25 g/min), auto shut-off, and a larger 200ml tank. Worth it for frequent ironers.

⚠️ Budget Warning

The Midea portable iron at ¥99 is even cheaper but has slower heat-up (40 sec) and weaker steam (10 g/min). The Deerma is worth the ¥20 premium.

Pros & Cons

FAQ

Q: Can the STS300 replace a traditional iron? A: For light-to-medium ironing, yes. For heavy creases, thick fabrics, or professional results, a traditional 1600W+ iron with stronger steam output is more suitable.

Q: How do I clean the STS300? A: Descale every 2-3 months by filling the tank with a 1:1 vinegar-water solution, heating for 2 minutes, and steaming into a cloth. Rinse with clean water afterward.

Q: Can I use tap water? A: Deerma recommends distilled or purified water to minimize mineral buildup. Tap water will eventually clog the steam vents.

Q: Does it work for vertical steaming? A: Yes, the STS300 can be used as a handheld steamer for hanging clothes. However, the modest steam output means results are better with the iron horizontal on a flat surface.

Q: Is the STS300 suitable for international travel? A: No, it’s 220V only. For international use, you’d need a 220V-110V step-down transformer, which is bulky. Consider a dual-voltage travel steamer instead.

Verdict

Rating: 4.4/5

The Deerma DEM-STS300 is a capable, affordable portable steam iron that excels at its intended use case — quick wrinkle removal for daily wear. The fast heat-up and foldable design are practical features at this price point. The small tank and modest steam output limit it to light-duty use, but for its target audience of students, travelers, and minimalists, it delivers solid value.
