Antminer S19j Pro (104Th) for Sale in the UAE
The Antminer S19j Pro is the used-market workhorse of the UAE, the most searched-for S19-family unit we supply, and the model most buyers have in mind when they ask for a tested used miner. Its 104 TH/s at 3,068 W won’t compete with current-generation efficiency, and it doesn’t need to. A massive deployed base, proven platform reliability, and low entry cost keep it the default first machine for budget builds across the UAE and the GCC. Most of our S19j Pro units move as bench-tested used stock from the Deira workshop, each with a recorded stability run and full documentation.
Who the S19j Pro Suits
Budget-first buyers entering SHA-256 mining at the lowest sensible cost, and operators scaling unit count where entry price per terahash matters more than efficiency per terahash. At 29.5 J/TH it’s a machine for cheap power: the math works at low tariffs and doesn’t at high ones. If your rate supports newer hardware, the S19K Pro is the same platform with meaningfully better efficiency, and the honest first comparison.

Condition, Testing & Warranty
Primarily supplied as tested used stock, and on this model the testing is the whole game. Every used unit runs the full protocol: bench test under load, recorded stability test at rated hashrate, hashrate and temperature log shared with you, factory-default firmware, and serial-number photos before dispatch.
Warranty depends on how you take delivery. Collected from our Deira workshop, a used unit carries a 3-day warranty handled case by case. Shipped outside Dubai, it carries none, and the testing evidence stands in its place: attend the test in person, or receive video of your unit running before it’s packed. We say this before you order rather than after.
Where a new unit is available instead, it ships sealed with a 12-month manufacturer’s warranty from Bitmain, claimed directly with them.
What Ships With It
Unit and power cables, original PSU where available and stated clearly in the quote when it isn’t. Used units come with the test log, the stability recording, and serial photos matching the tested unit to the shipped one.
Running It in the UAE
3,068 W continuous with the airflow needs of any air-cooled ASIC: commercial power, ventilation, no sealed rooms in summer. Nowhere to run it? Hosting takes it from bench to rack, and the repair workshop that tested it keeps standing behind it.
