Selecting a device farm box starts with how your QA or automation team will use it day to day. This guide covers the decisions that matter before you place a hardware order.

1. Match node count to your test matrix A 20-node starter box covers most small-to-mid QA teams running parallel app tests. If you need separate device groups for regression, compatibility, and staging builds, plan headroom or a second chassis rather than overloading one unit.

2. Cooling and power are not optional for 24/7 labs Passive desk setups overheat quickly above a handful of devices. Factory chassis use active multi-fan airflow and centralized PSUs sized for continuous operation. Ask your vendor about burn-in testing before shipment.

3. Plan your expansion path Start with a standard 2U box, then add expansion chassis or move to a custom rack when node count exceeds one box. Modular designs avoid replacing entire labs when you scale.

4. Confirm ADB and automation compatibility Verify USB debugging access, hub stability, and your test runner requirements before purchase. PhoneFarm Fun boxes ship ADB-ready; optional remote workstation setup is available as a service.

5. Include shipping and lead time in project planning In-stock SKUs typically ship in 3–5 business days from Guangzhou. Custom racks require a scoping call first.
