Product Overview
The Zalptic Z81 is an 82.5L dual-zone portable compressor fridge freezer for extended camping, larger groups and overlanding. Independently controlled 45L and 37.5L compartments let you carry chilled and frozen food at the same time, or set both zones to suit your supplies.
Key Features
- Two independently controlled zones: 45L left and 37.5L right. Use one as a fridge and the other as a freezer, or set both to fridge or freezer mode.
- Compressor cooling with a −20°C to +20°C temperature range gives control over chilled or frozen storage.
- 12V and 24V DC operation suits compatible vehicle and auxiliary battery systems; an AC adapter is included for mains use.
- Digital temperature display makes settings and operating temperature easy to check.
- Reversible lid with 180° opening provides flexible access in different vehicle and campsite layouts.
- Polyurethane insulation, a sealed lid and a high-efficiency DC compressor with conversion module help retain cold air and limit heat gain.
- CFC-free insulation.
- Three-stage low-voltage battery protection helps reduce excessive battery discharge.
- Interior LED lighting and removable baskets make loading, organisation and night-time access easier.
- Tie-down points help secure the fridge during travel; heavy-duty carry handles assist with transport.
- Interior drainage plug simplifies cleaning.
- Built-in bottle opener.
Applications
- Extended overlanding and remote travel.
- Family or group camping requiring fresh and frozen food together.
- Larger vehicle and trailer setups with sufficient space and a suitable external power system.
Why Choose This Product?
The Zalptic Z81 is the model to consider when you need separate chilled and frozen storage on the same trip. Its two independently controlled compartments provide more flexibility than a single-zone fridge, while the larger capacity suits longer journeys and well-equipped vehicles.
Important Notes
- Both compartments have independent temperature control.
- A suitable external power source is required. Solar-powered operation requires a compatible battery, charge regulator and correctly designed 12V or 24V DC system.
- Keep the compressor ventilation openings clear and allow airflow around the unit. Protect the fridge and electrical connections from water and submersion.
- Secure the unit using its tie-down points for vehicle and off-road travel. Check available space, lid access and ventilation before selecting a mounting position.
- Battery protection helps limit discharge but does not guarantee engine starting or a particular runtime. An auxiliary or dual-battery setup is recommended for overnight or multi-day use.
- Rated power is not a continuous consumption or battery runtime figure; actual energy use depends on operating conditions and temperature settings.
- An AC adapter is included. Check the adapter’s labelled input rating before connecting to mains power.
- Register with Zalptic within 30 days of purchase for the manufacturer’s 12-month full-unit and 24-month compressor warranty. Zalptic lists a 6-month limited manufacturer warranty for unregistered products. Warranty terms, exclusions and proof-of-purchase requirements apply; retain your receipt and serial number.
