Power Adapter Specifications
The Airthings Space Hub is powered via a dedicated DC power adapter (not batteries). If you need to replace a lost or damaged adapter, use one that matches the following specifications:
Output: 5V DC, 2.0–2.1A
Input: 100–240V AC, 50/60Hz
Connector: 5.5mm (outer) x 2.1mm (inner) barrel plug, center positive
Why the Voltage Matters
Always use a 5V DC adapter. Using an adapter with a higher voltage can damage the Hub and will be considered misuse, which voids the warranty. Make sure the connector polarity is center positive, reversed polarity can also damage the device.
Sourcing a Replacement Locally
If you need to buy a replacement adapter locally rather than through Airthings, any adapter that matches all three specifications above – Output (5V DC, 2.0–2.1A), Input (100–240V AC, 50/60Hz), and Connector (5.5mm x 2.1mm, center-positive barrel plug) – will work with your Space Hub, regardless of brand.
By using a correctly specified power adapter, you help ensure the long-term reliability of your Space Hub.
