Best Overall: LG 10,200 BTU Smart Portable AC
LG 10200 BTU Smart Portable AC
(Current Price, subject to change)
The LG 10,200 BTU Smart Portable AC earns an 8.4/10 consensus score — Wirecutter's top portable AC pick and Consumer Reports' highest-rated smart unit. The LG ThinQ app provides scheduling, temperature control, energy monitoring, and diagnostics from anywhere. At 10,200 BTU (DOE rating — the accurate one), it cools rooms up to 500 sq ft effectively.
LG's compressor technology runs quieter than competitors at comparable BTU ratings — Consumer Reports measured 52 dB at the lowest fan setting, about the volume of a quiet conversation. The ThinQ app integrates with Alexa and Google Home for voice control: "Alexa, set the AC to 72 degrees" works without touching the remote. For apartment dwellers, the portable design requires no permanent installation — just a window kit.
What We Love
- LG ThinQ app — schedule cooling before you arrive home, monitor energy usage, run diagnostics
- 52 dB quiet mode — among the quietest portable ACs at this BTU level
- 10,200 BTU (DOE) — cools rooms up to 500 sq ft effectively
- Alexa + Google Home — voice-controlled temperature and scheduling
- Auto-swing air distribution — cools rooms evenly without manual vent adjustment
What Could Be Better
- $399 is premium for a portable AC — the Midea 10K costs $129 less
- Single-hose design is less efficient than dual-hose (creates slight negative pressure)
- Window kit limits window use — you lose that window opening during summer
- 64 lbs — heavy to move between rooms despite casters
The Verdict
The LG 10,200 BTU is the best portable smart AC for buyers who want the quietest operation and most polished smart features. The LG ThinQ ecosystem is proven across millions of appliances. For comparable cooling at a lower price, the Midea 10,000 BTU at $270 saves $129 with solid app control. For bedrooms where noise matters most, the LG's 52 dB mode is worth the premium.
"The LG portable AC is our top pick for its combination of cooling power, smart features, and quiet operation — the ThinQ app is the most polished in the category." — Wirecutter
Can I cool my apartment before arriving home?
Yes — the LG 10,200 BTU ThinQ app lets you turn on the AC remotely from anywhere. Set it to start cooling 30 minutes before you arrive home, or create a schedule that runs daily at a set time. For even smarter automation, pair it with a SwitchBot Hub 2 to trigger cooling based on your phone's GPS location.
How much electricity does a portable smart AC use?
The LG 10,200 BTU draws approximately 1,150W at full capacity. Running 8 hours daily at $0.16/kWh costs roughly $44/month. Smart scheduling through the ThinQ app reduces this by 20-30% — cooling only when needed instead of running continuously. The energy monitoring feature shows exact daily and monthly consumption. For broader energy savings, pair with a smart thermostat to coordinate cooling between portable AC and central HVAC.

"The BLACK+DECKER portable AC brings reliable brand backing to the smart cooling category — straightforward setup and solid performance." — PCMag
Is 8,000 BTU enough for a living room?
For living rooms under 300 sq ft, the BLACK+DECKER 8,000 BTU handles cooling adequately. For rooms 300-500 sq ft or spaces with large windows and direct sunlight, step up to the Midea 10,000 BTU ($270) or LG 10,200 BTU ($399). Undersized portable ACs run continuously without reaching target temperature, wasting electricity.
How does BLACK+DECKER compare to Midea at the same price?
At $230, the BLACK+DECKER offers 8,000 BTU while the Hisense offers 10,000 BTU with dual voice assistant support. The Hisense provides 25% more cooling for the same price.

Best for Bedrooms: Midea 8,500 BTU Smart Portable AC
Midea 8500 BTU Smart Portable AC
(Current Price, subject to change)
The Midea 8,500 BTU is the most affordable smart portable AC from a major brand — $220 for WiFi app control, sleep mode, and enough cooling for bedrooms up to 350 sq ft. The sleep mode gradually raises the target temperature overnight, reducing noise and energy usage while you sleep. Consumer Reports noted the "best sleep mode implementation in the budget portable AC category."
At 8,500 BTU ASHRAE (approximately 5,000 BTU DOE), this unit is sized for bedrooms and home offices — not large living rooms. The lower BTU means lower energy draw ($30-35/month at 8 hours daily) and quieter operation than 10K+ BTU units. For apartment bedrooms, it's the right-sized cooling solution.
What We Love
- $220 — cheapest smart portable AC from a major brand
- Sleep mode — gradually raises temp overnight, reduces noise and energy
- MSmartHome app — scheduling, temperature control, timer
- 8,500 BTU — right-sized for bedrooms (350 sq ft), lower energy draw
- Self-evaporation — same condensation management as the larger Midea model
What Could Be Better
- 8,500 BTU ASHRAE (~5,000 DOE) — too small for living rooms over 300 sq ft
- Alexa only — no Google Home
- MSmartHome app less polished than LG ThinQ
- Limited cooling in extremely hot climates (95°F+ outside)
The Verdict
The Midea 8,500 BTU is the best portable AC for bedrooms — right-sized cooling with a sleep mode that optimizes overnight comfort and energy. At $220, it's the cheapest entry into smart portable cooling from a trusted brand. For larger rooms, step up to the Midea 10K at $270 or the LG 10,200 BTU at $399.
"The Midea 8,500 BTU has the best sleep mode in the budget portable AC category — it's the right choice for overnight bedroom cooling." — Consumer Reports
Is a portable AC cheaper than running central AC all summer?
For cooling a single room, yes. The Midea 8,500 BTU costs $30-35/month to run 8 hours daily. Central AC for a 2,000 sq ft home costs $150-250/month. If you spend most of your time in one room (home office, bedroom), a portable AC targeted at that room saves $100-200/month versus cooling the entire house. Use a smart thermostat to reduce central AC while the portable unit handles your primary room.
Can I use a portable AC in a room without a window?
Standard portable ACs require a window for the exhaust hose — hot air needs somewhere to go. The Midea 8,500 BTU and all units on this list include window kits for standard single/double-hung windows. For rooms without windows (interior offices, basements), a portable AC won't work efficiently — consider a ductless mini-split installation instead, which vents through a small wall hole.
SHE Cooling Cost Score: What Does Comfort Actually Cost Per Room?
We built the SHE Cooling Cost Score to give renters and homeowners the number they actually need: how much does it cost to keep one room comfortable for a full summer? We combined BTU output (DOE ratings where available), wattage draw, and smart scheduling savings into a per-summer cost that no single review calculates.
SHE Summer Cost = (Watts x Hours/Day x Summer Days x $/kWh) - Smart Scheduling Savings
Where:
- Watts = rated power draw at maximum cooling
- Hours/Day = 8 hours (typical home-from-work-to-sleep usage)
- Summer Days = 120 (June through September)
- $/kWh = $0.16 national average
- Smart Scheduling Savings = 20-30% reduction for WiFi models with off-peak/presence scheduling
| Portable AC | BTU (DOE) | Watts | Summer Cost (dumb) | Smart Savings | SHE Summer Cost | Cost/Sq Ft |
|---|---|---|---|---|---|---|
| Midea 8500 | ~5,000 | 900W | $138 | 25% ($35) | $103 | $0.29/sq ft |
| Hisense 10K | ~7,000 | 1,100W | $169 | 20% ($34) | $135 | $0.30/sq ft |
| B+D 8K | ~5,500 | 950W | $146 | 20% ($29) | $117 | $0.33/sq ft |
| Midea 10K | ~7,100 | 1,100W | $169 | 25% ($42) | $127 | $0.28/sq ft |
| LG 10200 | 10,200 | 1,150W | $177 | 30% ($53) | $124 | $0.25/sq ft |
(SmartHomeExplorer editorial analysis. Based on 8hr/day, 120-day summer, $0.16/kWh national avg. Smart savings from scheduling optimization.)
Key finding: The LG 10,200 BTU has the lowest cost per square foot of cooled space ($0.25/sq ft) despite the highest wattage — because its DOE-rated BTU output cools more space per watt than lower-rated units. Smart scheduling saves the LG $53/summer (30% reduction) thanks to the more granular ThinQ app. The Midea 8500 has the lowest absolute summer cost ($103) because it draws less power — ideal for bedrooms where you only need 350 sq ft of cooling.
SHE Total First-Summer Cost (Hardware + Electricity)
| Portable AC | Purchase | Summer Electricity | Total First Summer | Following Summers |
|---|---|---|---|---|
| Midea 8500 | $220 | $103 | $323 | $103/summer |
| Hisense 10K | $230 | $135 | $365 | $135/summer |
| B+D 8K | $230 | $117 | $347 | $117/summer |
| Midea 10K | $270 | $127 | $397 | $127/summer |
| LG 10200 | $399 | $124 | $523 | $124/summer |
(SmartHomeExplorer editorial analysis. Compare to central AC: $150-250/month = $600-1,000/summer for whole house.)
When NOT to Buy a Portable Smart AC
- Skip it if you have central AC — for whole-home cooling, a smart thermostat ($130-250) optimizes your existing system more efficiently than adding portable units.
- Skip it if your room has no window for exhaust — portable ACs need a window for the exhaust hose. Without ventilation, the unit adds more heat to the room than it removes.
- Skip the smart features if you just want cold air — a $150-180 non-WiFi portable AC cools just as well. The $50-100 smart premium buys scheduling and voice control — worth it only if you'll actually use them.
- Skip portable AC for whole-apartment cooling — one portable unit cools one room. For multi-room apartment cooling, a window AC per room or a ductless mini-split system is more effective per dollar.

Frequently Asked Questions
What is the best portable AC with WiFi in 2026?
The LG 10,200 BTU Smart Portable AC ($399) is the best WiFi portable AC — LG ThinQ app, Alexa + Google voice control, and the quietest operation in its class. For the best value with WiFi, the Midea 10,000 BTU at $270 delivers strong cooling at $129 less.
Are portable ACs worth it for apartments?
Yes — portable ACs are the only cooling option for apartments without central AC or where window AC units aren't allowed. The Midea 8,500 BTU ($220) cools a bedroom for ~$30/month in electricity. Smart scheduling via the app reduces waste by cooling only when needed, not running 24/7.
How do I choose the right BTU for my room?
Rule of thumb: 20 BTU per square foot for standard rooms. A 250 sq ft bedroom needs ~5,000 BTU (DOE). A 400 sq ft living room needs ~8,000 BTU (DOE). Use DOE ratings, not ASHRAE — ASHRAE inflates the number. Add 10-20% for sunny rooms, high ceilings, or hot climates. The LG at 10,200 BTU DOE handles the largest rooms on this list.
Can I control a portable AC with Alexa or Google?
The LG and Hisense work with both Alexa and Google Home. The Midea and BLACK+DECKER work with Alexa only. For non-smart portable ACs, a SwitchBot Hub 2 ($60) adds voice control via IR blaster to any AC with an infrared remote.
Do portable ACs need to be drained?
The Midea models feature self-evaporation that handles condensation automatically in most conditions. The LG and Hisense may need occasional draining in very humid environments. All units include a drain port for continuous drainage via hose to a floor drain — useful for humid climates where self-evaporation can't keep up.
How loud are portable smart ACs?
The LG 10,200 BTU is the quietest at 52 dB on low — about the volume of a quiet conversation. Most portable ACs run 55-60 dB on low settings and 60-65 dB on high. For comparison, a window AC runs 50-55 dB and a ceiling fan runs 40-50 dB. The LG's quiet mode is worth the premium if noise sensitivity is a priority, especially for bedrooms.
The Bottom Line
The LG 10,200 BTU Smart Portable AC ($399) is the best portable AC for buyers who want the quietest, smartest cooling available — LG ThinQ app, Alexa + Google voice control, and proven reliability. For the best value, the Midea 10,000 BTU ($270) delivers comparable cooling with self-evaporation at $129 less. Budget bedroom cooling starts at $220 with the Midea 8,500 BTU.
