Hi Ben, BioLite specifically state in their user manual (section 10 of the guide linked above if you want to read it in full) that the firepit should be stored in a dry location.

We recommend that this be in a garage or storage shed as even moisture in the outside air can have an effect over years of use, and the battery pack in particular is best stored away from any moisture.

It's a great firepit, but not one that is designed to be left out in the open all the time.

G'day,

There isn't a compatible pizza stone available for the Biolite Firepit, either by Biolite or aftermarket.
Pizza Stones are often available in varying sized round pieces, where as the firepit is quite narrow and rectangular.
With some baking paper and carefully controlled temperature you could probably bake a pizza in the Biolite Griddle.

G'day Coral,

This firepit has a portable battery pack attached that can power small accessories like lights or charge things like mobile phones.
Unlike the smaller Camp Stove this unit doesn't have a thermoelectric generator so it will need to be charged via 240/12v.

G'day Elly,

No, the FirePit doesn't come with a storage bag, but you can purchase one separately here.

G'day Wayne,

When in use, the FirePit stands at 41cm high. You'd need to check with the relevant authorities on Fraser Island, but I don't think they would classify this as an enclosed fire like an ozpig.

G'day Phil,

The fan being too noisy at full speed is, ultimately, subjective and depends on who you speak to.
With all fans, either stand-alone or within appliances, the noise increases with the speed.
As this is not actually an issue per say, there have been no amendments to the fan in the new version
Hope that helps!
