GekkoScience KBuddy 15-18TH 300W Home Heater Miner

The KBuddy is the compact sibling to the KBeast — a fully standalone ASIC miner with an integrated 300W power supply, built for anyone who wants real hashrate without the bulk or the power draw. Stock setting runs around 15 TH/s at 200W, with headroom to clock up to 18 TH/s at 300W max.

Like its bigger sibling, the KBuddy is built on GekkoScience's KBox platform and shares the same efficiency ceiling — down to 13 J/TH with tuning — powered by a built-in 94%-efficient Meanwell PSU that runs on 120V or 240V with a simple on/off switch.

Small footprint, real output. Designed to double as a space heater, the KBuddy is the easy entry point for home mining: lower power draw, lower price, and the same enclosed, no-exposed-electronics build quality as the rest of the lineup.

Built to run unattended.
