Avalon Q vs Mini3: Home Miner Showdown
Both Canaan‘s Avalon Q and Avalon Mini3 are designed for home deployment — quiet enough for residential settings, low enough power for standard circuits, real-enough hash to actually mine. But they target different homes. This guide picks between them.
Side by side
| Avalon Mini3 | Avalon Q | |
|---|---|---|
| Hash rate | 37.5 TH/s | 90 TH/s |
| Power draw | 750 W | 1,675 W |
| Voltage requirement | 110V or 220V | 220V single-phase |
| Circuit needed | Standard 110V/15A or 220V/10A | Dedicated 220V/15A |
| J/TH efficiency | 20 | 18.6 |
| Acoustic envelope | ~60 dB | ~65 dB |
| Form factor | Compact, fits on a shelf | Standard rack-style |
| Price (our markup) | $918 | $1,926 |
| Daily revenue (typical) | ~$1.40 | ~$3.30 |
| Daily power cost ($0.06/kWh) | ~$1.08 | ~$2.41 |
| Daily net | ~$0.32 | ~$0.89 |
Both are profitable at moderate residential power rates ($0.06–$0.09/kWh). Both are uneconomic above ~$0.12/kWh — at higher rates, even home-friendly hardware needs subsidized power (overnight rates, solar offset, etc.).
The deciding factor: your electrical infrastructure
The honest decision tree:
Do you have 220V available?
In North America, that means a dedicated outlet (NEMA 6-20 or similar) — typically requires running a new circuit from your panel to where the rig will live. An electrician charges $200–500 for this work depending on distance.
In Europe and most of Asia, 220V is your residential standard. A standard outlet works for the Avalon Q without modification.
- Yes, 220V available without electrical work: Avalon Q wins. 2.4x more hash, 2.8x more daily revenue, only marginally more noise.
- Yes, willing to install a 220V circuit: Avalon Q still wins, but the $200–500 electrical work eats some of the advantage. Payback on the work alone: 9–18 months at typical revenue.
- No, only 110V residential standard available: Mini3 on a 110V outlet. The Q won’t run on 110V (needs the higher voltage to deliver rated power).
Acoustic considerations
Both rigs are residential-friendly but neither is silent.
Mini3 at 60 dB: comparable to a normal conversation or a window AC unit. Tolerable in a closed room with a closed door, especially if the room is somewhat distant from bedrooms or living spaces. Vacuum-cleaner running constantly is a more visceral comparison than the dB number.
Avalon Q at 65 dB: comparable to highway traffic from 50 feet away. Louder than the Mini3 but still much quieter than the 75 dB flagships (Antminer S21 series). Manageable in a closed garage or basement; not in a living space.
Both benefit from acoustic treatment: closed-door room, sound-absorbing panels on adjacent walls, exhaust ducted away from occupied spaces. With basic treatment, either rig becomes essentially unnoticeable from anywhere except the immediate vicinity.
Heat output
The Mini3 produces ~2,560 BTU/hour of heat — equivalent to a small space heater. Manageable in a typical room without active extraction; the room will warm noticeably (5–10°C above ambient) but won’t reach throttling temperatures.
The Avalon Q produces ~5,700 BTU/hour — equivalent to a medium space heater. A closed room will hit thermal limits within an hour. Requires either room-scale ventilation, or deployment in a larger space (garage, basement) where the heat dissipates naturally.
For cold-climate operators: this heat is a feature, not a bug. See our mining-as-heat-source guide for using ASIC heat to offset home heating costs.
Daily revenue context
Neither rig will make you rich. The Mini3 nets ~$0.32/day at $0.06/kWh power; the Avalon Q nets ~$0.89/day. Annualized: $117 vs $325.
That’s the reality of “home mining” as a category. The economics are workable but modest. For meaningful daily revenue you need flagship hardware (S21 XP class) which requires industrial-style infrastructure most homes don’t have.
For some home operators, that’s fine — you’re treating mining as a hobby with positive cashflow rather than a primary income source. For others, the modest returns make hosting (where someone else manages industrial-grade infrastructure) more attractive. See our home vs hosted comparison.
Payback math
At $0.06/kWh power and steady BTC price:
- Mini3: $918 / $0.32/day = ~2,870 days = ~8 years to fully pay back capex
- Avalon Q: $1,926 / $0.89/day = ~2,164 days = ~6 years
Both payback periods exceed typical hardware economic lifespan (3 years). Translation: at moderate residential electricity rates, neither home miner pays back its capex purely from mining revenue.
This sounds like bad news but it isn’t necessarily — the rig’s value to you also includes mining education, optionality on BTC price appreciation (your daily BTC accumulation is a bet that BTC outperforms USD), and resale value at end of operational life.

The honest summary
If you have 220V residential power and don’t mind a bit of fan noise: Avalon Q. More hash, faster payback, real daily revenue.
If you’re stuck on 110V circuits or want a genuinely quiet home setup: Avalon Mini3. Less revenue but lower-friction deployment.
If you want bigger numbers: skip both, get a Tier 3 home setup (S21++ or A1566 in a detached garage). For broader context: Canaan Avalon buyer’s guide.
