Exo Terra HabiSphere Desktop Terrarium Transformer
The right power adapter for a HabiSphere, not a universal one. This is the Exo Terra HabiSphere Desktop Terrarium transformer (model PT3804-AUS) – the mains power adapter that runs the day/night LED lighting built into the Exo Terra HabiSphere desktop terrarium (model PT3835). It's sold as a replacement for a lost, damaged or faulty original adapter.
Note: this is a power adapter only, not the terrarium itself. If you're after the HabiSphere terrarium, look for the Exo Terra HabiSphere Desktop Terrarium (PT3835).
Key features
- Purpose-built for the HabiSphere's integrated LED lighting – not a generic low-voltage adapter.
- DC barrel plug output – matches the HabiSphere's power input port.
- Australian mains variant – article number PT3804-AUS, wired for the Australian 240 V / 50 Hz mains supply and AU plug.
- Black finish – matches the HabiSphere's housing.

Compatibility
Fits the Exo Terra HabiSphere Desktop Terrarium (PT3835) only. It hasn't been tested here against other Exo Terra low-voltage fixtures, so don't assume it interchanges with a different Exo Terra product's adapter even if the connector looks similar.
Safety
The HabiSphere's integrated LED lighting unit and this adapter are not waterproof – keep both away from water spray, misting and high humidity, and never submerge either in water. Not designed for outdoor use or freezing conditions.
Warranty and delivery
Covered by your rights under Australian Consumer Law.
Common questions
Will this power any other Exo Terra terrarium or fixture?
No – it's built specifically for the HabiSphere Desktop Terrarium (PT3835) and shouldn't be assumed to fit other Exo Terra low-voltage products.
What plug does this come with?
The AU market variant (PT3804-AUS), wired for Australian mains and an AU plug, with a DC barrel plug output to the HabiSphere.
My HabiSphere still won't light up after I replace the adapter – what now?
Check the HabiSphere's own LED unit and internal connections next, since a replacement adapter only rules out the power supply itself as the fault. Get in touch with us if you're still stuck.
