Product Introduction
DragonBall Miner A21 is an ASIC mining device developed for the NexaPow algorithm, supporting consistent output when mining NEXA. It delivers a hashrate of 3.4Gh/s with a power draw of 1800W, forming a stable operating profile for continuous deployment. From the start, the hardware design emphasizes predictable electrical behavior, controlled heat flow, and steady calculation output during long operation cycles.
At the same time, the internal structure centers on dedicated NexaPow chips that maintain stable calculation rhythms across extended workloads. Power modules distribute current evenly, while cooling components guide airflow through defined paths. As a result, the system sustains output levels without frequent adjustment. Meanwhile, noise control and airflow planning support organized installation layouts and consistent spacing between units.
Key Technical Specifications
- Designed specifically for the NexaPow algorithm
- Rated hashrate of 3.4Gh/s under standard conditions
- Power consumption measured at 1800W
- Integrated air-cooling system with structured airflow paths
- Pre-shipment power-on and hashrate verification
In parallel, the thermal system combines multiple fans with aligned heatsinks to regulate internal temperatures during continuous use. The enclosure directs air intake and exhaust along fixed routes, which helps limit internal heat buildup. At this stage, regulated power input handling supports steady operation within standard electrical environments.
DragonBall Miner A21 fits structured mining setups that require stable operation and controlled power planning. Over time, the device supports long runtime cycles and follows routine maintenance schedules common in ASIC deployments. Component selection prioritizes durability under sustained electrical and thermal load rather than short-term output spikes.
Before shipment, technicians perform full operational testing, including power-on checks and hashrate confirmation. After testing, logistics teams coordinate international delivery through established warehouse channels, which helps align shipping schedules and reduce transit uncertainty. Packaging follows standardized protective practices for long-distance transport.
Within Nexa-focused mining configurations, DragonBall Miner A21 supports consistent participation in NexaPow-based networks. Its configuration allows steady operation without reliance on variable tuning methods, supporting predictable performance across extended operation periods.
