Most home miners do one job. A Bitcoin miner runs SHA-256 and nothing else, and a Dogecoin miner runs scrypt and nothing else, so mining both has meant two boxes, two plugs and two dashboards.
The Harlo H15 Dual puts both in one case. It mines Bitcoin and Dogecoin at the same time, on two different algorithms, from one power cord.
Here is what two algorithms means, which coins each side can mine, what Harlo OS adds on top, and what Batch 1 looks like.
Two algorithms, one box
Bitcoin is secured by SHA-256, which needs raw speed and almost no memory. Dogecoin and Litecoin use scrypt, which is memory hard on purpose. The two need different silicon: a Bitcoin chip cannot mine Dogecoin at all, and a scrypt chip cannot mine Bitcoin.
The H15 carries both kinds of chip and runs them at the same time: SHA-256 to Bitcoin on one side, scrypt to Dogecoin and Litecoin on the other.
One viewer put the appeal of that like this:
“I wish this had been around when I got started. It would have saved me some time trying to decide which algorithm to start with. Definitely interested.”

What you can mine, by algorithm
Each side of the H15 mines the coins that share its algorithm. These are the ones our product page and our Harlo OS pages name.
SHA-256 side · BM1373 chips
BitcoinThe main event. Solo for the full block reward, or any pool you choose.
Bitcoin CashThe same SHA-256 algorithm. Harlo OS can send a slice of your hash to a Bitcoin Cash pool; JD split a Magic Miner 40T between Bitcoin and Bitcoin Cash on camera.
About 15 TH/s on this side.
Scrypt side · dedicated scrypt chip
DogecoinMerge mined with Litecoin, so the same work counts toward both chains.
LitecoinMined together with Dogecoin on a merged mining pool. The Dogecoin guide shows how.
About 1.08 GH/s on this side.
One H15 runs both sides at the same time. The Bitcoin side and the Dogecoin and Litecoin side hash in parallel, in the same box, on the same plug.
What is inside the box
The H15 pairs the new BM1373 chips for SHA-256 with a dedicated scrypt chip for Dogecoin and Litecoin. Both run at once, in one chassis, from one plug, cooled by fans and a heatsink.
| Spec | Harlo H15 Dual |
|---|---|
| Bitcoin (SHA-256) | about 15 TH/s |
| Dogecoin and Litecoin (scrypt) | about 1.08 GH/s |
| Power usage | about 500 W |
| Noise | about 50 dB |
| Network | 2.4 GHz WiFi and Ethernet |
| Power supply | built in, power cord in the box |
| Cooling | fans and a heatsink |
From the product page's spec list.
One box, one plug
The power supply is built in, so there is no brick to buy or wire. It runs from a normal outlet on a standard IEC C14 computer cord, and it does not need a dedicated circuit.
Nearly every watt a miner draws ends up as heat, so at about 500 W it also warms the room it sits in. We cover that side in heat your home with a Bitcoin miner.
Another viewer summed up the one box idea:
“Pretty cool that they made something to dual mine! Small box instead of two boxes! Genius!!”

What Red Panda Mining said
Red Panda Mining went over the H15 on the day Batch 1 opened.
To be clear about what the video is: he does not have an H15 yet, and goes over the specs from our product page with a case of the same size on his desk. HeliumDeploy also sent him the Hammer Miner DC06 units he gives away in the video, and his link to the H15 is an affiliate link. On how it would fit in a home, he said:
“this is probably going to make for a really great little heater for a bedroom, not like a bigger kitchen or a living room”
Red Panda Mining, A New Dual Bitcoin + Dogecoin Miner Just Dropped!
And his overall take:
“I think it could be a solid unit.”

He also said he thinks the price could come down a bit.
Harlo OS: dual mining meets quad pool mining
Bitcoin and Bitcoin Cash on the SHA-256 side, Dogecoin and Litecoin together on the scrypt side, all from one box.
The H15 is compatible with Harlo OS, the firmware Harlo Labs builds for home miners. It does not come preloaded; you put it on when you want it.
Quad pool mining splits your hash across up to four pools at once, and you set the percentage each one gets. An even split looks like this:
| Feature | What it does | Why it matters |
|---|---|---|
| Dual mining | SHA-256 and scrypt at the same time, in one box, on one plug. | Bitcoin plus Dogecoin and Litecoin without a second machine. Nothing like it has been seen before in a home miner. |
| Quad pool mining | Up to four pools at once, with a percentage split you set. | Solo mine Bitcoin with one slice and point the rest wherever you like. |
| Stratum speed test | Tests the latency of pools from your own house. | You pick the fastest pool for where you live, not just the default. |
| Tuning and power modes | Raise or lower clocks on the fly, with a warning before you push past stock. | Run it quieter or harder when you choose. |
| Fan control | Set the fans yourself or let an automatic fan curve follow the temperature. | You choose the balance between noise and heat. |
| Scheduled tasks | Downclock, overclock or pause mining by time of day. | Ease off by day and run harder at night without touching it. |
| True power | Reads the real watts from the wall through a Matter smart plug. | The number on your dashboard matches your meter. |
| Diagnostics and Discord support | Hashrate, temperatures and power in one live view, and the developer in the Harlo Discord. | When something looks off, you see it and you can ask the person who wrote it. |
| Harlo OS on the H15 | Compatible, not preloaded. | You install it when you want it. |

Who this is for
- You want Bitcoin and Dogecoin at home without running two machines.
- You have a room that could use about 500 W of warmth.
- You like choosing your own pools and would put Harlo OS on it.
- You are fine waiting for Batch 1 to ship on November 14, 2026.
Who should wait
- You need a miner running before November 14, 2026.
- You only want Bitcoin. A SHA-256 only miner does that one job on its own.
- You want the most scrypt hashrate in one box. A dedicated scrypt miner goes further there.
- You need a bedroom with no sound at all. It runs at about 50 dB, quiet but not silent.
Batch 1: 50 units at $999
Batch 1 is 50 units at $999, and the product page says it ships November 14, 2026.
If you have wanted Bitcoin and Dogecoin on your desk without two machines, this box does both.
