The iPhone 18 Pro Max is the biggest phone in Apple’s 2026 Pro line-up, pairing the A20 Pro chip and variable-aperture camera with the larger display and longer battery life of the two Pro models. Our refurbished iPhone 18 Pro Max handsets cost less than buying from Apple, and every one is fully tested, unlocked and covered by a 12-month warranty.
Prefer something easier to hold? The refurbished iPhone 18 Pro has the same chip and cameras in a smaller body. For a bigger saving, the refurbished iPhone 17 Pro Max is last year’s large-screen Pro at a lower price.

The Pro Max is the iPhone for people who use their phone for everything: shooting video, editing photos, gaming, streaming and working on the move. The bigger screen makes all of that easier, and the larger battery means less time hunting for a charger. Buying it refurbished is simply a cheaper way in, with no difference in what the phone can do.
Before any iPhone 18 Pro Max reaches you, it goes through our multi-point inspection of the display, battery, cameras, buttons and connectivity, and it’s checked against lost and stolen databases. Delivery is free across the UK, you’ve got 30 days to return it, and the 12-month warranty comes as standard. Spreading the cost is easy too, with interest-free options at checkout through Klarna and others.
If you want the most screen you can get, you’ve now got two choices. The iPhone 18 Pro Max is a traditional phone with a triple camera system, including a telephoto lens, while the iPhone Duo folds open into Apple’s largest display yet but has two rear cameras rather than three. For zoom photography and all-day battery, the Pro Max is the safer bet.
Weighing up older large models? Compare it with the iPhone 17 Pro Max and iPhone 16 Pro Max, or browse all our refurbished iPhones. A phone this size deserves proper protection, so have a look at our cases and tempered glass, and pair it with AirPods if you’re after the full setup.
Why buy a refurbished iPhone 18 Pro Max instead of new?
It’s the same phone for less money. A refurbished iPhone 18 Pro Max from The iOutlet has been fully tested, checked against lost and stolen databases and comes unlocked with a 12-month warranty, free UK delivery and 30-day returns.
How much does a refurbished iPhone 18 Pro Max cost compared with new?
Apple charges from £1,299 for the 256GB iPhone 18 Pro Max, rising to £2,499 for 2TB. Our refurbished prices are currently around £130 to £250 lower depending on storage, and the grid above always shows today’s prices.
Is the iPhone 18 Pro Max worth it over the iPhone 18 Pro?
It is if screen size and battery life matter most to you. The two phones share the A20 Pro chip and camera system, so the Pro Max isn’t faster or better at photos. You’re paying for the larger display and longer battery life.
What’s the difference between the iPhone 18 Pro Max and iPhone 17 Pro Max?
The 18 Pro Max brings the newer A20 Pro chip, a variable-aperture main camera, a smaller Dynamic Island and next-generation cooling. Both top out at 2TB of storage. If you don’t need the latest features, a refurbished iPhone 17 Pro Max saves you more.
Should I buy the iPhone 18 Pro Max or the iPhone Duo?
Pick the Pro Max if you want the stronger camera, including a telephoto lens, and a phone that costs less and is simpler to live with. Pick the iPhone Duo if you want the biggest screen on any iPhone in a design that folds to pocket size. Both use the A20 Pro chip.
What colours and storage options does the iPhone 18 Pro Max come in?
The iPhone 18 Pro Max comes in Black, Silver, Glacier and Burgundy, with 256GB, 512GB, 1TB and 2TB storage. Which combinations we have depends on stock, so check the grid above for what’s available today.
What condition grades are available for the iPhone 18 Pro Max?
We grade every phone on its cosmetic condition. A+ (Pristine) shows no visible wear. A (Excellent) has minimal signs of use, such as light scratches. B (Good) shows moderate wear. C (Average) has heavier cosmetic wear. Every grade has passed the same functional tests and comes with the same 12-month warranty. As the iPhone 18 Pro Max has only just launched, most of our stock is A+ Pristine.
Does the iPhone 18 Pro Max support Apple Intelligence and Siri AI?
Yes. It runs iOS 27 with Apple Intelligence and Siri AI on the A20 Pro chip, and a refurbished handset receives the same software updates as a new one.
Is a refurbished iPhone 18 Pro Max unlocked?
Yes. Every iPhone 18 Pro Max we sell is unlocked and works on any UK network, so you can keep your current SIM or eSIM plan.
What battery health does a refurbished iPhone 18 Pro Max have?
Every refurbished iPhone 18 Pro Max from The iOutlet has a battery holding at least 80% of its original capacity. With the model this new, most are well above that.
