- Don't use dual-battery adaptors, and never combine two batteries at different charge levels.

Frequently asked questions
Which bundle should I choose?
For a 12V fridge, or several devices at once, choose the PRO bundle (15A, with a 12V socket and USB-C). For lights, fans and pumps, the standard bundle (up to 10A) is enough.
Do both items fit the same battery?
Yes. The power supply and the charger in each bundle are made for the same battery brand.
Can I buy the items separately?
Yes. Each is also sold on its own in our Volt Step Down PRO, 18V to 12V Power Supplies and In-Car Battery Chargers collections.
Are batteries included?
No. Both items run on or charge the 18–20V tool batteries you already own.
How much is delivery and where do you send?
We deliver anywhere in Australia. Shipping is calculated at checkout from your address and the items in your order, and every delivery includes in-transit insurance. We send with Australia Post, FedEx or DHL depending on the size and weight of your order.
Can I pick up my order instead?
Yes. Choose Pickup In-Store at checkout and collect your order from our store at 14 Cessna Street, Marcoola, on the Sunshine Coast. It saves the shipping cost.
Do you ship overseas?
Yes, for everything except awnings. International shipping is calculated at checkout, not including local import duties and taxes, which the receiver pays. For an overseas quote on an awning, email info@mrswagman.com.au or call +61 (0)7 5302 6954.
What's the warranty?
Every Mr Swagman product has a 12-month warranty against manufacturing defects, such as stitching or a seam coming apart, or a zip, buckle or pole failing in normal use. It starts on the day you receive the product, and it's in addition to your rights under the Australian Consumer Law.
Can I return it if I change my mind?
Yes, within 30 days of receiving it, as long as it's unused and in its original packaging. Please contact us first. You pay the return freight, the original shipping cost isn't refunded, and a 5% restocking fee comes off your refund, which we process once the item is back with us and approved for resale. If anything arrives faulty, damaged or not as described, that's different: contact us and we'll sort it out under the Australian Consumer Law, with no restocking fee.
What should I do when my order arrives?
Check the box and the product for damage before you sign for it. If there's any damage, note it with the driver before signing, or refuse the delivery. Without that, we can't claim on the freight insurance.
