The Invercrigil 10400mAh unit is documented as a utilitarian DC-to-DC buffer featuring a 4-cell lithium-ion array with a 3.7V nominal per-cell rating. A DC-DC buck/boost converter manages voltage output across 5V, 9V, and 12V rails. Signal analysis indicates that the absence of an AC inverter prevents the introduction of electromagnetic interference (EMI) often associated with modified sine wave UPS units. The 10400mAh capacity facilitates approximately 4 to 6 hours of operation for a 12W router.
Structural analysis identifies a passive cooling system, which requires adequate environmental airflow to prevent thermal throttling if the 12V rail load exceeds 2A. The device provides a zero-millisecond transfer time, supporting the simultaneous operation of an ONT and a router on different voltage rails. Component analysis suggests the internal batteries are non-serviceable and the chassis is compatible with standard DC barrel jacks.
If your infrastructure includes high-performance mesh nodes with power draws exceeding 24W, the SKE 625VA is a recommended alternative due to its higher real power limit and standard AC outlet support.
