Ebit E9.2 Miner 12T: Profitable Ebang Crypto Mining Equipment?

In an industry monopolized by Bitmain, the name of another Bitcoin (BTC) mining equipment company – for better or for worse – is hard to think of. This can happen even with a lesser known manufacturer trying to get a product out on a large scale and still offering fairly competitive prices.

It is for these reasons that Zhejiang Ebang Communication announced its SHA-256 Ebit E9.2 12T Miner. So the company is now committed to attracting the attention of the mining industry not only because of its introduction into a market dominated by big business but also because of its bold claims to provide a hashrate of 12 TH/s with a power consumption rate of 1320 watts.

But will this really work? Here we bring you the review and guide to everything about the E9.2 Miner:

E9.2 Miner Specifications

The E9.2 Miner is a predecessor of the E9 Ebit, which had been launched in 2017. This new iteration of the E9 series is an improvement over the previous model, almost doubling the previous hashrate of 6.3 TH/s that the E9 promised with its power consumption of 910 watts (which was 140 W/T compared to 110 W/T of E9.2).

Hashrate and power consumption are not the only aspects that have been improved in the E9.2, as it has improved specifications in almost all aspects.

Let's review the most crucial specifications and their real-world effectiveness to determine whether Ebit E9.2 is worth getting at its specified price of $ 750 per unit.


As such the hashrate for E9.2 is 12 TH/s, with a -5% ~ +10% variable. It means that while the projected hashrate remains at 12 TH/s, it may well fluctuate and may not be the same.


The chips used in the E9.2 are DW1228. These 10 nm chips were manufactured for Ebang by Samsung last year and were the same chips that the company had originally used in E10. Since the industry standard, today is the creation and use of 16 nm chips, these 10 nm chips are considered a popular upgrade and are not widely used by other manufacturers.

Energy Consumption

Power consumption for the E9.2 Miner remains at 1320 watts. It has been observed through various means that the power consumption remains true to its increased variable more than the specified value, which often makes it go over 1500 watts. The nominal voltage, marketed by Ebang, is said to be 11.8 V ~ 13.0 V.

The $ 750 unit, which is the only option available on Ebang's official website, is sold without a power supply. The recommended power supply for use with the miner is the 1800 watt – 2000 watt per Ebit power supply, which costs about $100 dollars.

Weight and Dimensions

The E9.2 unit weighs around 4.7 kg – which is a good weight compared to other devices. Most miners of this size come in the same weight. While the dimensions of the unit are 290mm x 126mm x 155mm. It is also on par with industry standards.

Fans and Temperature

The E9.2 comes with 2 fans that are installed inside the unit to ensure that its recommended temperature of being between 0 °C – 40 °C is optimally maintained. The projected humidity is 5% – 95%.

Noise level

The noise level for the E9.2 is presented in 70db. Which is actually in line with the performance of the previous miners manufactured by Ebang.

Comparison With Bitmain Antminer S9I-14 TH/S With PSU

Priced at $ 650 and with a bootable power supply, the Bitmain Antminer S9i-14 TH/s with power supply is the most relevant competitive unit for Ebit E9.2.

The Antminer features a projected 14TH/s hashrate, as the name implies. However, while its ideal hashrate exceeds that of E9.2 12TH/s, it fails in other respects.

By comparison, Antminer excels in terms of hashrate, weight, and even takes the cake in energy consumption, but the potential effects it delivers with 16nm chips is lower than what E9.2 brings to the table with the most advanced 10nm.

It's no secret that Bitmain excels in the overall efficiency of its mining units, as well as in after-sales support in case things go wrong for its users, which is one of the many reasons it has achieved its status as the one governing the cryptocurrency mine space. At the same time, Bitmain was able to create a very good product that had a very high acceptance rate.

Ebang, on the other hand, does not seem to have the same level of skill and that is why it falls in terms of user adaptability. This also leads us to talk about Ebang's current problems in terms of customer service and support.

Ebang's customer service leaves a lot to be desired. So it does not seem to have a very good reputation when it comes to after sales service or even the provision of the specified service without any noticeable interruption.

“They could barely support it when they had 1 or 2 and I’m just talking firmware updates, hardware support never really seems to have existed.” A user on BitcoinTalk mentioned when sharing their views on the upcoming line of products by Ebang.

While another user mentioned that the units are not well maintained and that it would not be a wise decision to trust them completely.

“Yeah a bit. They’re loud and hot and not the most reliable. I wouldn’t recommend them for home use. If you’re keeping them in your garage or a shed, a couple would be OK.” The user explained before adding that it would be advisable to get something else for a larger system.

Is the E9.2 Miner E9.2 Worth It?

If you are looking for a configuration that is ready for sound and maintenance, then going with the E9.2 Miner will be a very good choice. However, that is only until you look at the comparison with Antminer S9i in terms of price and expected returns.

The first comparison is with the hashrate provided by the companies, with the profitability calculated on the basis of $0.12 dollars, the average rate in kWh of electricity in the USA, and BTC with a rate of $8,175 dollars.

So we could say that the Antminer would be providing its users with more than double the benefits of Ebit9.2.

Now, let's take a look at the profitability of both miners with a higher energy consumption rate but with the same cost of $ 0.12 kWh.

As shown above, Ebit E9.2 appears to be lagging far behind in profitability when higher energy consumption was incorporated into the mix.

This, together with Bitmain's history of supplying high quality miners which, in most cases, remain true to projected rates of return and energy consumption; and the relative lack of familiarity with the Ebang and Ebit brand, as well as its customers comments in the past, allude to the fact that Ebit9.2 lost this battle to the Antminer S9i 14 TH/s.

The final deciding factor is the price. Not only do users have to pay up to $750 for Ebit9.2, but since it also comes without a power supply, $100 above it will be added to make it functional by $850.

While the Antminer S9i is not only available at a cheaper price of $ 650, it also comes with a power supply. This makes it about $200 less expensive than Ebit9.2, and the above-mentioned brand recognition and after-sales support features only add to its charm.

If you also think about the resale value, then the fact that it would be much easier to sell an Antminer than an Ebit miner in case of emergency would also be obvious.

Therefore, while the Ebit9.2 comes with a lower chip size and the promise of greater efficiency, it is outperformed by the more economical, well known and hashrate higher counterpart it has unfortunately found in the Antminer S9i.
