Solid State TEC technology — no compressor, no refrigerant, no moving parts. 20W only. Inverter compatible. 24-hour delivery Delhi NCR.
Important: Temperature Performance — Read Before Buying
The Qube cools to 8°C–10°C below ambient temperature, not to an absolute 8°C. At 32°C ambient, interior reaches ~22–24°C. At 40°C ambient (Delhi summer), interior will be ~30–32°C — suitable for beverages and chocolates but not for medicines or dairy requiring strict cold chain. Best in air-conditioned rooms or cooler environments. Not a replacement for a compressor refrigerator.
No compressor. No refrigerant. No noise. No defrosting.
Solid State TEC cooling. 20W. Inverter compatible.

How Solid State TEC (Peltier) cooling works — and why it achieves what no compressor fridge can
The Peltier effect is a thermoelectric phenomenon discovered in 1834: when direct current is passed through a junction of two dissimilar semiconductor materials, heat is transferred from one side of the junction to the other — one face of the thermoelectric module becomes cold (the cooling face, directed into the Qube's interior) and the opposite face becomes hot (the heat rejection face, directed outward with a small heat sink and fan on the exterior). There are no moving parts in this process at all — the heat transfer occurs entirely through electron movement in the semiconductor lattice, with no mechanical compression, no refrigerant phase change, and no pump. The Peltier module in the Godrej Qube achieves a temperature differential (ΔT) of 8°C–10°C between the interior and the exterior ambient temperature. This is both the core specification and the key limitation to understand: the Qube does not cool to a fixed absolute temperature — it maintains a fixed difference from whatever the surrounding air temperature happens to be. In a 28°C air-conditioned room, the Qube maintains approximately 18–20°C interior — well below room temperature, ideal for beverages, chocolates, and medicines requiring cool (not cold) storage. In a 32°C room, interior reaches approximately 22–24°C — still cooler than ambient and suitable for the same applications. In a 40°C Delhi summer without air conditioning, the interior would be approximately 30–32°C — which may not be perceptibly cooler than ambient in a way that benefits most contents. The design implication: the Qube performs best in environments that are already temperature-controlled (offices with AC, hotel rooms, air-conditioned retail counters) or in cooler seasons. What it delivers that no compressor fridge can match: absolute silence (critical for bedroom placement), 20W power consumption (one-third the power of a single LED tube light, running continuously at negligible electricity cost), and portable flexibility that comes from 11 kg weight and inverter compatibility.
20W power consumption + inverter compatibility — the economics of personal TEC cooling
The Godrej Qube's 20W rated power consumption is among the lowest of any active cooling appliance available in India — for context, a standard 5W LED bulb and the Qube together draw 25W total. Running the Qube continuously for 24 hours consumes 0.48 kWh (20W × 24h ÷ 1000) — at Delhi NCR's domestic electricity tariff of approximately ₹5–8/kWh for the first 200 units, the Qube costs approximately ₹2.40–₹3.84 per day to operate, or approximately ₹72–₹115 per month. A standard compressor mini fridge (80–120W) costs ₹9.60–₹23 per day for the same continuous operation. Over a year, the Qube's electricity saving vs a compressor mini fridge is approximately ₹3,000–₹7,000 — a meaningful contribution to the total cost of ownership calculation. The inverter compatibility is the second practical advantage: at 20W draw and 0.3A current, the Qube operates within the capacity of essentially any household inverter (even a 300VA entry-level inverter, which typically has 250W usable capacity), meaning the Qube continues cooling during power cuts without a dedicated circuit or capacity upgrade. For Delhi NCR households that experience 2–6 hours of power cuts in summer, inverter-compatible 20W draw means beverages in the Qube stay at the cooled temperature through any realistic power outage — supported further by the 5cm PUF insulation's 180-minute cooling retention, which maintains interior temperature for 3 hours even with the unit completely powered off.
5cm PUF insulation + 180-minute retention + Dual LED — build quality details
Polyurethane Foam (PUF) insulation is the industry-standard thermal barrier in refrigeration — the same material used in full-size refrigerator walls, cold storage panels, and vaccine carriers. The Qube's 5cm PUF thickness is notably generous for a 30L personal cooler; comparable thermoelectric coolers in the market typically use 2–3cm insulation. The practical benefit of 5cm thickness: the insulation's thermal resistance (R-value) increases proportionally with thickness, meaning the Qube's walls resist heat ingress from the outside environment approximately twice as effectively as 2.5cm-insulated alternatives. The stated 180-minute cooling retention — the period during which the interior temperature remains at the cooled level after the unit is switched off — is a direct function of this insulation quality. For a household that turns the Qube off at night (to eliminate even the minimal fan noise of the exterior heat sink) and back on in the morning, the 180-minute retention means beverages placed in the Qube the night before remain at the cooled temperature well into the morning. The Dual LED interior lighting serves the specific use case of the Qube's primary placement scenarios — beside the desk, on a hotel room counter, in a puja room — where low-profile interior lighting makes contents immediately visible without the harsh glare of fluorescent tubes, and where LED energy efficiency adds negligible consumption to the already-minimal 20W base draw.
Zero noise operation — the use case where TEC cooling is definitively superior to compressor cooling
A compressor mini fridge generates noise through two mechanisms: the compressor motor itself (a rhythmic mechanical hum at 35–45 dB that cycles on and off throughout the day and night as the thermostat triggers the compressor to maintain temperature) and the vibration transmitted through the cabinet and supporting surface when the compressor runs. In a bedroom context, compressor cycling — particularly the startling sound of the compressor engaging after a period of silence — consistently disrupts light sleep. Sleep medicine research identifies noise above 30 dB as potentially disruptive to sleep architecture, with compressor cycles at 35–45 dB falling clearly in the disruptive range for light sleepers. The Godrej Qube has zero compressor cycling because it has no compressor — the Peltier module operates continuously and silently, with only a small exterior-mounted heat sink fan producing minimal airflow noise (specified as negligible rather than rated dB in the product documentation, consistent with thermoelectric coolers generally measuring 20–25 dB at 1 metre — below the threshold of ambient room noise in most environments). For placement on a bedside table in a PG or hotel room (a primary target use case for the Qube), the silence is not an incidental feature but the principal advantage over any compressor-based alternative. The combination of 0 operational noise, 20W electricity consumption, and compact 30L footprint makes the Qube the appropriate cooling solution specifically for sleep environments, study rooms, meditation spaces, and any setting where compressor cycling noise is incompatible with the primary activity.

No Defrosting Required
Thermoelectric cooling does not create ice formation — there is no evaporator coil to frost over. No weekly shutdown for manual defrost, no frozen water drainage. The interior stays dry and clean with only occasional wiping.
Zero Moving Parts — Minimal Maintenance
The only moving component is the small exterior cooling fan. No compressor to service, no refrigerant to recharge, no belt or pulley to replace. Maintenance over the Qube's operating life is limited to cleaning the exterior heat sink fins annually.
11 kg — Genuinely Portable
At 11 kg and compact 46×44×49 cm, the Qube is light enough for one person to carry between rooms, relocate for events, or take to a new PG accommodation. A compressor mini fridge of comparable capacity weighs 18–25 kg.
