Black Jack Electric Trailer Jacks

The three models are designed for different caravan sizes and budgets. The Mini is the lightest and most affordable option, handling caravans up to 3500kg with a 1000kg lift capacity - great if you're watching your spend or working with limited space on your A-frame. The Master steps things up with a 1600kg lift capacity and suits caravans up to 4000kg, plus it comes with a folding foot which is handy for storage. The Maxi is the top-of-the-range model - it uses a ball bearing worm drive that's faster, quieter, and more efficient, handles caravans up to 5000kg with a 2000kg lift capacity, and it's the only electric trailer jack in Australia that comes with a remote control.

It comes down to your van's weight and what features matter to you. If your caravan is in the 2000-3500kg range, the Black Jack Mini will do the job nicely and keeps the cost down. For mid-size vans sitting between 3000-4000kg, the Master is a solid middle-ground choice - especially if you like the idea of a folding foot. If you're towing something heavier (up to 4500kg) or you just want the best setup available, the Maxi is worth the investment, particularly for the remote control and smoother drive system.

Yes - that's actually one of the Mini's biggest selling points. It's designed to fit straight into a standard 50mm jockey wheel clamp bracket, so you don't need to buy any extra mounting hardware or modify your A-frame. It also has three mounting positions to give you some flexibility. If you've already got a 50mm bracket and want a simple upgrade to electric, the Mini makes it very straightforward.

It does - and it's a genuine point of difference. The Maxi is the only electric trailer jack available in Australia that includes remote control operation. You actually get two remotes in the box, so you've got a spare handy. Being able to operate the jack without standing right next to the A-frame is a real convenience, particularly when you're hitching up solo or manoeuvring in a tight campsite.

Each model comes with a solid kit to get you going. All three include the jack unit itself (with Safe Auto Stop built in), an all-weather cover, a foot pad, and a manual handle for backup use. The Master and Maxi both include the patented clamp bracket and a folding foot as well. The Maxi also adds two remote controls. The Mini comes ready with a pre-installed Anderson plug connector. Basically, everything you need for installation and use is in the box.

Safe Auto Stop is a built-in safety feature included on all three Black Jack models. It automatically cuts the motor when the jack reaches the end of its travel, preventing it from over-running and potentially damaging the unit or your caravan. It's a simple feature but an important one - without it, you'd need to manually time the stop perfectly every time. Having it built in means you can operate the jack confidently without worrying about over-extending it.

All three Black Jack models - the Mini, Master, and Maxi - come with a 3-year warranty. That's a solid coverage period for an electric product that gets regular outdoor use, and it reflects the build quality across the range.

A good rule of thumb is to choose a model with a lift capacity comfortably above your caravan's actual towball download weight (not the total van weight). The Black Jack Mini lifts up to 1000kg and suits vans up to 3500kg. The Master handles up to 1600kg lift capacity for vans up to 4000kg. The Maxi tops out at 2000kg lift capacity for larger rigs up to 5000kg. If you're unsure of your towball download weight, check your caravan's compliance plate or manufacturer specs - it's worth getting right before you choose your electric trailer jack.
