DayBox Premium Cover at the beach
Made for your DayBox

Keep the cold in. Push the day longer.

The Premium Cover wraps your DayBox in a thick, double-wall insulating layer that slows heat gain, so the compressor works less and your battery lasts longer. Protection and performance, tailored to fit.

The DayBox Difference

50%
longer runtime, fitted

Your DayBox does the cooling. The cover keeps that cold where it belongs. Double-wall insulation slows heat getting in, so the compressor cycles less and holds temperature for up to 50% more hours on the same charge. Add a spare battery in the pocket to double your runtime again.

Less compressor work More hours of cold Spare battery = double it

Up to 50% longer runtime with the cover fitted vs. uncovered, in DayBox testing. Real-world results vary with ambient temperature, lid use and mode.

How it works

Double-Wall Insulation,
Engineered to Hold the Cold

It's not magic, it's good thermal design. Four layers keep the heat out and your charge working longer.

  • Weather-resistant outer shell

    Tough, wipe-clean fabric that shrugs off sun, splashes, dust and knocks.

  • Thick thermal core

    A dense double-wall layer that dramatically slows how fast outside heat reaches your drinks.

  • Reflective inner lining

    Bounces radiant heat back out, keeping the interior cooler for longer.

  • Snug, tailored fit

    Cut precisely for the 12L or 18L so there are no gaps for warm air to sneak in.

  • Up to 50% longer runtime

    Less heat in means less compressor work, and more hours of cold from the same battery.

  • Steadier temperatures

    Parked in the sun at the beach or bouncing in the back of the ute, the cover buffers against temperature swings.

  • Quieter, calmer cooling

    Fewer compressor cycles means you hear it less. Handy on quiet campsites and overnight.

Built-in storage

A pocket made for your spare battery

The Premium Cover has a padded side pocket with a velcro flap, shaped around the DayBox spare battery. Slot it in, flap it shut, and hot-swap when you need it. Cables and chargers travel with the box, not loose in your boot.

  • A spare battery fits perfectlySnug, secure and ready for a hot-swap.
  • Cords & chargers, sortedUSB-C cables and your car DC lead stay tidy and tangle-free in one place.
  • Room for a volt dropperCharging on the move? There's space for a volt dropper and lead too.
  • One grab-and-go unitEverything you need rides with the box. No hunting for the charger at 6am.

Protection that looks the part

Keeps your DayBox looking new.

Beaches scratch. Boots scuff. UV fades. The Premium Cover takes the hits so your DayBox doesn't, guarding it from scrapes, sun and grime. The handle cutout keeps the carry handle clear, and the tailored lines look as good as the box underneath.

Cover Questions, Answered

How does it give up to 50% longer runtime?+
The double-wall insulation slows heat getting in, so the compressor cycles less and the same charge lasts up to 50% longer in our testing. For the biggest gains, keep the DayBox in the shade.
Will it fit my DayBox?+
Yes. The cover is custom-cut for each size: choose the 12L Cover for the 12L DayBox, or the 18L Cover for the 18L.
What fits in the storage pocket?+
The DayBox spare battery, plus USB-C cables, your car DC lead and a volt dropper.
Can I carry the DayBox with the cover on?+
Yes. A handle cutout keeps the carry handle clear, so the cover stays on while you move it.
Does it really double my runtime?+
The cover extends runtime by holding the cold in. The jump to double comes from carrying a charged spare battery in the pocket and hot-swapping it in seconds.
Is the cover weatherproof?+
The tough outer fabric handles sun, splashes and dust. Water-resistant, not submersible, and wipes clean.
Is there a warranty?+
Yes. 12 months from purchase, with free shipping on warranty claims within Australia.

Up to 50% longer runtime.
