AEG-Compatible 18V to 12V Power Supply + Auto Charger Bundle

Everything to run camp on AEG 18V batteries: a power supply for your 12V gear, plus an in-car charger that tops the batteries up while you drive. Arrive with full batteries for the fridge by day, and the lights, fans and phone charging in the swag at night.

What's in the bundle

  • 18V to 12V Power Supply: adjustable 5–13V at up to 10A through an Anderson plug, with a voltage display. Runs lights, fans, pumps and smaller 12V loads.
  • Auto Charger: plugs into your vehicle's 12V or 24V socket and charges 18–20V batteries at 2A.

Fridge runtime

At temperature, a 12V fridge draws about 1 amp on average, so a 12Ah battery gives roughly 12 hours. Pre-cool the fridge first; hot weather shortens runtime.

Before you buy

  • Fits AEG 18V slide-on batteries. Battery not included.
  • Both items are made for the same battery brand.
  • Don't use dual-battery adaptors, and never combine two batteries at different charge levels. Both can damage the batteries.
  • Charge with the engine running so you don't flatten your vehicle's starting battery, unless you have a dual-battery system.

Goes well with

AEG is a trade mark of its owner. This is an aftermarket product, compatible with AEG 18V batteries but not made, approved or endorsed by AEG.

One battery family

Both items fit the same tool batteries, so any charged battery runs your gear.

Rotate your batteries

Charge one battery on the drive while another runs the camp, and swap at night.

Add camp lighting

Our 18V LED light and 100mm fan run on the same batteries, in the swag or around camp.

Frequently asked questions

Does it come with a battery?

No. It fits the AEG 18V batteries you already own. A bigger battery (higher Ah) runs your gear for longer.

Which bundle should I choose?

For a 12V fridge or several devices at once, choose the PRO bundle (15A, 12V socket and USB-C). For lights, fans and pumps, the standard power supply bundle (up to 10A) is enough.

Can I charge with the engine off?

You can, but the charger draws from your vehicle battery. Unless you have a dual-battery system, charge while the engine is running.

How are Off-Grid Power products delivered?

They're sent from our Australian warehouse partner, separately from our swags and awnings, so if you order both you'll receive more than one parcel.

  • Shipping is free within Australia when your Off-Grid Power products total over $200. Below that, shipping is calculated at checkout.
  • Orders placed before midday on a business day are usually dispatched the same day; later orders go the next business day.
  • Most deliveries arrive within 1 to 6 business days of dispatch. Regional and remote areas can take longer.
  • You'll get tracking details by email once your order is on its way.

Off-Grid Power products can't be picked up from our Marcoola store.

Can I return an Off-Grid Power product if I change my mind?

Yes, within 30 days of delivery.

  • It must be unused, in its original condition and packaging, with proof of purchase.
  • Contact us first. We'll give you the return address, which is different from our Marcoola store. Items sent back without approval may not be accepted.
  • You pay the return freight, and the original shipping cost isn't refunded.
  • A 5% restocking fee is deducted from your refund.

We don't do direct exchanges: return the item and place a new order for the one you want.

What if it arrives faulty or damaged?

Check your order when it arrives. If anything is faulty, damaged or not what you ordered, stop using it and contact us within 14 days of delivery with your order number and photos.

Off-Grid Power products are covered by the consumer guarantees under the Australian Consumer Law. Where a fault is confirmed, we'll arrange a repair, replacement or refund and cover the reasonable return freight. Our 12-month Mr Swagman warranty covers our own camping gear, not the Off-Grid Power range.
