Pushing a powerful \u003cstrong\u003e310 kH\/s\u003c\/strong\u003e, it significantly boosts your odds of mining a block compared to standard V2 models. Unique to this hardware is its dual-connector structure (USB-A male and female), allowing you to physically daisy-chain up to 10 devices on a single 5V-3A power supply. Beyond mining, it serves as a high-precision, dual-purpose USB power meter, monitoring voltage and current for your electronic ecosystem.\u003c\/p\u003e\n\n\u003ch3\u003ePerformance Accolades \u0026amp; Standards\u003c\/h3\u003e\n\u003cp\u003eDriven by the \u003cstrong\u003eESP32-S3FN8 Xtensa dual-core processor\u003c\/strong\u003e (240MHz), this device balances thermal stability with high hash output.
