iPhone 18 Accessories

A new iPhone turns up with a phone in the box and not much else. No charger, no case, no screen protector, which means the iPhone 18 accessories you pick decide how fast it charges and how well it survives the first drop.

Our range covers all of it. MagSafe compatible phone cases, tempered glass screen protectors, GaN wall chargers, USB-C cables, Qi2 wireless chargers and Power Banks, designed in Melbourne since 2003 and backed by a 2-year warranty.

What iPhone 18 accessories do you actually need first

Three things on day one. A case, a screen protector and a proper wall charger, because an old 5W plug leaves a new phone trickling overnight for no reason.

Here is the order we would buy in:

• A MagSafe compatible case keeps magnetic charging, wallets and mounts working without pulling the case off every time.
• A tempered glass screen protector takes the scratch that would otherwise cost you a screen replacement.
• A USB-C wall charger between [VERIFY: 20W and 45W] gets you a real top up in the time it takes to shower.
• A USB-C cable rated to your charger's wattage stops the cable being the slow part of the chain.

After that, a Power Bank and a car mount are the two that get used every week.

How MagSafe and Qi2 magnetic charging work

MagSafe is the ring of magnets built into your iPhone that snaps accessories into exactly the right spot. Qi2 is the open wireless charging standard built on that same magnetic alignment, so the charger finds the coil instead of you nudging the phone around a flat pad.

Alignment is the whole point. A flat pad that sits slightly off centre charges slower and runs hotter, while a magnetic charger locks on and holds.

The Wireless Power Consortium lifted the Qi2 ceiling from 15W to 25W with its Qi2 25W release in 2025, which is why magnetic wireless charging has stopped feeling like the slow option. Cygnett's Qi2 Wireless Chargers deliver up to [VERIFY: wattage]W to compatible iPhones.

One catch worth knowing. A case without magnets in it will weaken or block that alignment, so if you want wireless charging to work properly, the case needs to be magnetic too.

Which charger is right for your iPhone

Match the wattage to how you actually charge, not to the biggest number on the shelf.

• 20W is the everyday pick for bedside and desk charging, and it is the cheapest way to get fast charging at all.
• 30W to 45W is for people who charge in short bursts before walking out the door, and it has enough headroom for an iPad as well.
• 65W and above with a multiport layout runs a phone and a laptop from a single wall socket, which is the one to travel with.

Power Delivery (PD) is the standard that lets the charger and the phone agree on the right wattage instead of guessing, and every Cygnett iPhone Wall Charger uses it. GaN stands for gallium nitride, a material that runs cooler than silicon, which is how a GaN charger fits a high wattage into a plug small enough to leave in your bag.

Car chargers follow the same logic. A dual port car charger covers the driver's phone and a passenger's device on one adaptor, and a magnetic car mount that charges as well keeps the phone powered and visible without a cable across the console.

Do older MagSafe accessories still fit a new iPhone

Magnetic accessories almost always carry over. A Cygnett MagSafe compatible charger, wallet or mount bought for an iPhone 13 or iPhone 14 will still snap onto a newer magnetic iPhone, because the magnet array has been consistent across every MagSafe iPhone since the iPhone 12. The same goes for USB-C cables and wall chargers, where USB-C is simply USB-C.

Cases and screen protectors are the exception. Both are cut to one model's exact dimensions, so an iPhone 15 Pro case will not fit a different body and an iPhone 16 Pro screen protector will not line up with a different display. Those are the two iPhone accessories you replace on every upgrade.

One thing to check. Older 15W magnetic chargers still work on newer iPhones, they just charge at the older speed rather than the current Qi2 ceiling.

What to look for in a case and screen protector

Cases and protection come down to four things, and the listing should tell you all four.

• Drop protection is stated as a tested drop height rather than a vague promise, so check the rating on the product page. [VERIFY: drop ratings for the iPhone 18 case range]
• Magnet strength decides whether the case holds on a car mount over a speed bump or slides off at the first roundabout.
• Cutouts need to clear every button and lens, including the Camera Control on recent models. [VERIFY: Camera Control on iPhone 18]
• Tempered glass rates harder than plastic film and takes the scratch instead of the display underneath.

Privacy screen protectors are the pick if you read work email on the train. They narrow the viewing angle until the person beside you sees a dark screen.

What to pack for travel, the car and the gym

Travel is where a Power Bank earns its place. A 10,000mAh Power Bank is the pocketable size for a day out, and 20,000mAh covers a long-haul flight with a tablet as well. Anything under 100Wh, roughly 27,000mAh, is carry-on approved. Always check with your airline before flying.

Around the house, a multiport wireless charging station clears a phone, AirPods and a watch onto one plug instead of three. Away from it, a magnetic Power Bank that snaps to the back of the phone keeps mobile gaming and long map sessions alive, since gaming flattens a battery faster than anything else you do on a phone.

The rest of the kit rounds it out. AirPods Cases stop your earbuds rattling loose in a bag, an AirTag holder tracks the valuables you would hate to lose, and silicone Apple Watch bands handle sweat better than leather for health and fitness use.

Frequently asked questions

Do iPhone 18 MagSafe accessories work with older iPhone models?

Magnetic chargers, wallets and mounts work across every MagSafe iPhone from the iPhone 12 onward, because the magnet array has stayed consistent. Cases and screen protectors are the exception, since both are cut to one model's exact dimensions. Charging speed on older models is capped at whatever that phone supports.

Which charger is right for my iPhone?

A 20W USB-C charger covers everyday bedside and desk charging. Step up to 30W or 45W for fast top ups before heading out, or a multiport 65W charger if a laptop shares the plug. Power Delivery lets the charger and phone agree on the safest speed automatically.

What iPhone accessories do I need when I'm travelling?

A Power Bank, a USB-C cable, a multiport wall charger and a travel adaptor cover almost every trip. Choose a Power Bank under 100Wh, roughly 27,000mAh, so it is carry-on approved, and check with your airline before flying. A magnetic Power Bank saves cable space.

What accessories come with a new iPhone?

A new iPhone ships with a USB-C cable in the box and nothing else. No wall charger, no case, no screen protector. Those three are the accessories to sort on day one, since the cable alone will not fast charge without a wall charger to plug it into.
