100a ANL fuse

​2 X 100a ANL fuse & holder

One to protect the battery charger, one to protect the rest of the electrical system

Note: Whilst a DC to DC battery charger is preferable (and necessary if you have a lithium battery), I understand it is a little expensive! As a cheaper alternative, you could get a Durite split charge relay kit instead. However given the closeness in price and massive difference in performance, I still highly recommend getting the 60a DC to DC battery charger.

Shore Power Kit ⚓

Shore power allows you to hook up your van at a campsite and charge up!

Butyl tape

​Butyl tape

For sealing the fan on the roof

Note: The Maxxair Maxxfan Deluxe is the most popular campervan fan for a reason - it's the best on the market. It is quiet, has 10 speeds, and can be used when its raining. However it is expensive. As a cheaper alternative, you could get the 2012 campervan roof vent.

Campervan fridge 🥒

Another campervan essential. Somewhere to store your vegetables and freeze your ice cream! Related Reading: Best campervan fridges


Note: The Dometic CRX CoolMatic is considered one of the best 12v compressor fridges on the market. However, it is pricey. You can find cheaper 12v fridges on Amazon like this one (note it doesn't have a freezer).

12v Campervan Lights 💡

Van conversions will typically be kitted out with a mix puck lights and LED strip lights.
