What Exact Antminer Models Did MinerSource Have in Stock on July 22?
A stock list can look long and confusing. We get it. That is why we break down our warehouse sheet into clear, specific models. Buyers do not need marketing words. They need exact hashrate numbers and power specs.
We had six distinct S21 family models in stock: the S21 Pro 234T, the S21 Pro+ 245T, the S21++ in 216T, 225T, and 235T versions, and the S21 151T.
Each model serves a different type of mining operation. We keep this variety because one buyer’s “perfect” miner is another buyer’s wrong fit. The details matter.
A Detailed Look at Our July 22 Inventory
We prepared the table below for buyers who compare specs side-by-side. These are the units our team physically checked and packed on that day.
| Stock Name | Public Model Label | Hashrate | Power | Efficiency | Key Notes |
|---|---|---|---|---|---|
| S21 Pro+ 234T | Antminer S21 Pro (234Th) | 234 TH/s | 3510W | 15 J/TH | Air-cooled, 2 fans, 75dB, Ethernet. Operates in 5 – 45 °C, 5 – 95% humidity. |
| S21 Pro+ 245T | Antminer S21 Pro+ 245T | 245 TH/s | 3500W – 3675W | 15.0 J/TH | Air-cooled, dual fans. A strong, efficient SHA-256 Bitcoin miner. |
| S21++ 216T | Antminer S21+ (216Th) | 216 TH/s | 3564W | 16.5 J/TH | Air-cooled, 22.9 kg. First batch was Feb 2025. A solid mid-high option. |
| S21++ 225T | Antminer S21+ (225Th) | 225 TH/s | 3712W | 16.498 J/TH | Air-cooled, 2 fans, 75dB, Ethernet. Works best in 10 – 40 °C, 5 – 95% humidity. |
| S21++ 235T | Antminer S21+ (235Th) | 235 TH/s | 3877W | 16.498 J/TH | Air-cooled, 2 fans, 75dB, Ethernet. For buyers who want stronger output. |
| S21 151T | Antminer S21 151T | 151 TH/s | 2642W – 3247W | 17.5 – 21.5 J/T | Air-cooled, 220V–277V input. A simpler entry point for Bitcoin mining. |
What Should Buyers Notice First?
The three strongest models in this list are the 234T, 245T, and 235T. They give the most hashrate per unit. A Canadian client who runs a hydro-cooled farm told us the 245T fits their setup perfectly. They can plug in fewer machines but hit their target hashrate goal. The 216T and 225T models are a great middle ground for facilities that want a balance of power and output. The 151T unit is our go-to recommendation for smaller-scale enthusiasts who need a lower entry point.
Why Does a Physical Hong Kong Warehouse Matter for Your Order?
A real address on a website is easy to write. A real warehouse with physical stock is much harder to fake. When you send a large payment, you are sending trust. You need to know that trust is backed by real machines sitting on real shelves.
A physical Hong Kong warehouse reduces delays, lowers your risk, and turns global shipping into a simple process for your business.
Hong Kong is one of the world’s busiest logistics hubs. For our company, this location is a strategic choice. It means your order does not get stuck in a slow inland shipping process before it even reaches the port.
What a Real Warehouse Means for You
We use a simple table to explain what our warehouse setup means for a buyer’s daily concerns.
| Your Concern | What Our Hong Kong Setup Means |
|---|---|
| “Is the stock a promise or a reality?” | The units were physically in our warehouse. We took real photos and videos on July 22. |
| “Can I get a fast turnaround?” | Yes. Our team can pack an order as soon as payment is confirmed. No factory wait times. |
| “I need a large batch for my new farm.” | We support wholesale and bulk orders from this warehouse. One European client ordered 50 S21++ 235T units from this batch, and they shipped within two business days. |
| “How does the payment and shipping flow work?” | The process is clear. We confirm stock, you confirm the order, we ship. You can review every step on our Shipping & Payment Policies page. |
How Do These S21 Miners Compare on Real-World Performance?
Hashrate, power, and efficiency are the three main numbers on every miner’s datasheet. But those numbers are just a starting point. The real question is what those numbers mean for your operation when the machine is running 24/7.
The S21 Pro models lead on efficiency, the S21++ models offer strong hashrate variety, and the S21 151T gives a dependable lower-wattage entry point.
A miner with 15 J/TH efficiency makes a big difference compared to one with 21.5 J/TH if your electricity cost is high. A buyer in Dubai with higher power rates might only look at the S21 Pro series. A buyer in a region with cheap power might prefer the lower upfront cost of the S21++ 216T.
Head-to-Head Performance Snapshot
We organized the key performance data so you can make a fast, informed decision.
| Model | Hashrate | Power | Efficiency | Best Practical Fit |
|---|---|---|---|---|
| S21 Pro (234Th) | 234 TH/s | 3510W | 15 J/TH | A proven choice for buyers who want strong efficiency and a wide operating temp range. |
| S21 Pro+ 245T | 245 TH/s | 3500W – 3675W | 15.0 J/TH | Buyers who want the highest hashrate in our stock with top-tier efficiency. |
| S21++ 216T | 216 TH/s | 3564W | 16.5 J/TH | Buyers who want a solid, later-batch S21 family option at a different price point. |
| S21++ 225T | 225 TH/s | 3712W | 16.498 J/TH | A direct step up from the 216T for those who need more output in the same family. |
| S21++ 235T | 235 TH/s | 3877W | 16.498 J/TH | Buyers who prioritize raw hashrate in the S21+ class and have adequate power capacity. |
| S21 151T | 151 TH/s | 2642W – 3247W | 17.5 – 21.5 J/T | Buyers who need a lower-wattage model for smaller setups or specific power limits. |
The Practical Difference on Your Shelf
Let’s say you have 100 kW of power capacity. You could run about 28 units of the S21 Pro+ 245T. You could run around 38 units of the S21 151T. The total hashrate you get from those two setups is very different. The choice always comes back to your power capacity, your cooling setup, and your electricity cost. We ask these three questions on every sales call before we recommend a model.
What Steps Should a Smart Buyer Take Before Ordering?
A big stock update creates urgency. It is tempting to rush an order just to secure the machines. But a smart buyer takes five minutes to verify the details first. That five minutes can prevent a costly mismatch between the miner and the mining site.
Before you place an order, confirm the model name, check live stock, lock in the price, and give our team your shipping destination and power setup.
Mining hardware prices move quickly. A model that has 200 units in stock today might have 10 units tomorrow. That is the normal rhythm of this market. We see it every week.
Your Pre-Order Checklist
We recommend you have clear answers for these points before you send a payment.
- Exact Model Confirmation: Do not just say “S21++.” Say “S21++ 235T.” The difference in hashrate and price is too big to guess.
- Current Stock Availability: Ask our team to confirm live stock on the day you plan to pay.
- Latest Unit Price: Get a fresh quote. Do not rely on a price from a week ago.
- Full Shipping Address: Provide the final destination. Shipping to a farm in rural Texas is not the same as shipping to a business address in Frankfurt.
- Power and Cooling Specs: Tell us your voltage limits and your cooling method (air, hydro, or immersion). A miner that needs 277V will not work on a 220V setup.
- Order Scale: A small batch for testing needs different support than a full container order.
We recently helped a buyer from the UAE who needed 80 units. They confirmed the model, sent their facility’s power specs, and we checked compatibility before payment. That step took one extra hour, and it saved them a huge headache. The fastest way to start this process is to reach us through our Contact page. You can also browse our Antminer Parts page if you need PSUs or fans alongside the miners.
Conclusion
On July 22, 2026, our Hong Kong warehouse was not a paper stock list. It was a physical inventory of Antminer S21 Pro+, S21++, and S21 units. Every machine was ready to be packed, labeled, and shipped to a buyer’s door anywhere in North America, Europe, Dubai, or beyond.
