Price in listing is per individual block erupter.

Pristine condition. Functions great. Tested with cgminer. See photos.

Please know that these are NOT profitable Bitcoin miners. Technically, these are the least powerful ASIC miners ever releasedThey are more than 10 years old (released in 2013) and were one of the first types of ASIC miners to reach the public. They are now massively inadequate in terms of mining power by todays standards. They are to be viewed as neat collectible pieces of bitcoin history and memorabilia. Great for learning, gifting, tinkering with, and are fun to try and solo "lotto" mine with. If your looking to make a profit, please look elsewhere.

Please do your own research before purchasing this item. Many bitcoin mining pools do not recognize miners with a hash rate of under 1000 MH/s (1 GH/s) when pointed to their pools. Even if they did, this miner would never contribute enough hash power to ever accumulate enough Bitcoin to reach a payout threshold.

For perspective: 
- The Block Erupter in this listing hashes at 330 MH/s and earns $0.00 per day by pool mining
- An Antminer s19 Pro hashes at 110, 000, 000 MH/s and earns around $5 - $25 USD per day by pool mining (before electricity costs)

You would need over 13,213 individual Block Erupter USB sticks all running together, pointed at the same pool, in order to generate ~$1 a day worth of bitcoin. Even then it would take almost a month to reach a payout threshold (~0.00100000 btc depending on the pool).

These are not plug-and-play devices. You will need to:
  • Download and install the drivers (Silicon Labs VCP USB Device Drivers. No drivers required if running on a linux device such as Ubuntu or Raspian)
  • Download and configure the mining software (Cgminer, BFGMiner being popular choices)
  • Connect the mining software to a solo or shared mining pool of your choice
  • Provide adequate cooling to the device. These do get hot when mining (a small fan is recommended)
I've received many messages asking if this could be used to mine doge or ethereumThe answer is no. The ASIC Miner Block Erupter is a 330 MH/s SHA256 miner. That means that it can only mine coins that use the SHA256 algorithm such as bitcoin, bitcoin cash, bitcoin SV, DigiByte, and almost 100 other coins. Having said that, please keep in mind that these miners are antiquated, so it isn't going to be effective in mining much of anything. 

Some Interesting History About Bitcoin Mining and the Asicminer USB Block Erupter:
On January 30th, 2013 Jeff Garzik received the first commercially available ASIC Bitcoin miner (Avalon miner). Just 4 months later, another company named ASICMiner released the first ever USB powered ASIC Bitcoin miner for the home hobbyist. The Block Erupter came in 11 color variations and originally retailed for 1.99 BTC a piece at the official release date on May 2013. Market value for 1.99 BTC was around $200-$225 USD at the time.

While the Block Erupter wasn’t the first ASIC miner released, it was the smallest and the first ever to use the USB form factor for power. It also used the first ever ASIC chip ever produced; The 130nm BE100.

Great functioning condition but they may have very minor cosmetic scuffs and/or small scratches on the top.

The Block Erupter has a green LED light that turns on when it is powered on, and blinks when it’s hashing/mining. 

Model: ASIC USB Block Erupter Bitcoin Miner 330 MH/s Sapphire Rev 3.00
Interface: USB
Type of Miner: ASIC (SHA256)
Power use: 5v 500mA = 2.55 watts
