🚨 The NEW Harlo B30 might be one of the most impressive Home Bitcoin Miners I've tested in 2026!
👀But forget the marketing numbers for a second… What does this thing ACTUALLY deliver when you plug it into the wall?
Huge shoutout to the team at
@Heliumdeploy for sending over the brand-new Harlo Labs B30 for some REAL-WORLD TESTING!

I spent several hours putting this miner through its paces, testing all 3 power modes, measuring actual watts at the wall, comparing efficiency, and even swapping the firmware over to HarloOS.
🔥And I've got to say… the results surprised me!
📊 MY REAL-WORLD TEST RESULTS (HarloOS)
🟢 LOW / ECO MODE
⚡ Hashrate: 12.3 TH/s
🔌 Power Consumption: 156 Watts
📈 Efficiency: 12.68 J/TH
🟡 MEDIUM / BALANCED MODE
⚡ Hashrate: 24.4 TH/s
🔌 Power Consumption: 328 Watts
📈 Efficiency: 13.44 J/TH
🔴 HIGH / TURBO MODE
⚡ Hashrate: 30.6 TH/s
🔌 Power Consumption: 486 Watts
📈 Efficiency: 15.88 J/TH
Now here's where things get REALLY interesting!
Helium Deploy advertises the B30 at 30 TH/s while consuming 485 Watts in Turbo Mode.
My testing? 30.6 TH/s at just 486 Watts!
That's slightly MORE hashrate than advertised while practically matching the advertised power consumption!
And in Balanced Mode, we're talking 24.4 TH/s at 328 Watts, compared to the advertised 24 TH/s at 350 Watts.
Not too shabby!
But the BIGGEST surprise for me was actually the firmware.
Out of the box, the miner was running a different operating system, GLOD-OS, and during my initial Turbo testing, I saw power consumption climb to approximately 510 Watts after 25 mins, finally breaking 30 TH/s.
After installing HarloOS? We were hitting 30 TH/s much faster, and my final testing came in at just 486 Watts with 30.6 TH/s!
Even the HarloOS firmware's estimated power consumption was incredibly close to what I measured at the wall across all three modes.
Now, there IS a tradeoff. Running Turbo with HarloOS pushed noise levels up to around 71–72 dB during testing. So if you're planning to run this in a living space, that's definitely something to consider.
The great news? You have options! Different power modes, adjustable fans, multiple mining pools, scheduling, and plenty of customization.
That's what makes this miner so interesting for home Bitcoin mining.
🏠You can prioritize maximum hashrate, dial things back for better efficiency, or potentially put that heat to good use during the colder months.
📊 Check out the graphic below! I put together a full comparison of my REAL-WORLD results against both the HarloOS firmware settings and Helium Deploy's advertised specifications.
💬 What do you think? Would you run the Harlo B30 at 30+ TH/s, or would you sacrifice some hashrate for better efficiency and lower power consumption?
