Apple’s iPhone Duo folds into a shape phones haven’t really had before, and that changes what a case, a charger, or a screen protector needs to do. ESR noticed. Its accessory lineup for the iPhone Duo and the iPhone 18 Pro and Pro Max doesn’t treat these phones like slightly bigger versions of last year’s model. It builds around the hinge, the fold, and how people actually hold these things.
ESR has been making phone accessories since 2009, and it shows in how confidently this lineup comes together. Four products anchor it: a vegan leather case with a built-in stand, a screen protector built around Corning glass, a magnetic charging pad with active cooling, and a retractable wall charger made for travel. Each one solves a different part of daily life with the new iPhone, starting with the case.
ESR Atelier Magnetic Case with Flex Stand
The Atelier case is where ESR’s design ambitions show up first, and the Deep Burgundy finish makes the case, pun intended. It uses organic silicone leather that feels closer to a wallet than a phone shell, soft to the touch with a grain that resists fingerprints and daily grime. An anti-fouling coating keeps the lighter trim looking new, so it ages more like a handbag than plastic.
The iPhone Duo version centers on a Flex Stand that finally makes sense on a folding phone. When opened, it can rotate a full 180 degrees, supporting portrait and landscape viewing whether the phone is folded shut or opened flat, and doubles as a secure grip in hand. Zinc alloy and a damping hinge keep it locked at any angle, and ESR says it survives 3,000 open-and-close cycles without loosening.
Closing the stand also forms a lip around the camera lenses, shielding them from direct contact with tables or countertops. The rest of the case follows the same foldable logic, with hinge padding, a soft microfiber lining, a TPU frame, and raised edges around the screen. A 1,400g magnet on the back locks onto MagSafe chargers, car mounts, wallets, and power banks.
The iPhone 18 Pro and Pro Max version sports the same dual-function Flex Stand but trades the grip function for a simpler adjustable stand, tilting between 15 and 69 degrees for portrait or landscape viewing. A built-in cover keeps the Camera Control button protected without getting in the way, while the same 1,400g magnet, aligned by a precise ring layout, locks onto MagSafe gear just as securely.

ESR UltraFit Armorite® Pro Screen Protector
Screen protectors usually get bolted on as an afterthought, but this one leads with durability first. It’s built from Accessory Glass by Corning, the same company that’s supplied Apple’s cover glass since the very first iPhone, and ESR rates it at up to 10 times the impact absorption of generic protectors. Corning’s own testing also credits it with up to twice the scratch resistance of standard glass.
That toughness doesn’t come at the cost of clarity. An anti-reflective coating tunes light reflection down to just 3.75%, with 94% optical transmittance, so colors read truer and glare backs off in bright rooms or direct sun. Installation skips the bubble wrestling match: a tray system aligns the protector automatically, and pulling one tab clears dust and pushes out air for a clean, edge-to-edge fit in two steps.

Cyclone 25W Magnetic Charging Pad with CryoBoost
The Cyclone’s real advantage becomes clear before the battery bar even climbs halfway. Its Qi2 25W charging combines with a CryoBoost fan that pulls heat off the phone’s back, a pairing ESR says charges a phone to 50% noticeably faster than Apple’s own charger. That same active cooling drops temperatures by about 11.7°F, easing the heat buildup that erodes battery health over time.
Beyond the charging speed, the Cyclone earns its desk space with practical touches. Its built-in stand tilts from 0 to 150 degrees, supporting both portrait and landscape viewing; the latter also enables StandBy mode. It stays whisper-quiet under 25dB even overnight, which also makes it a perfect bedside accessory. Paired with an ESR magnetic case, the pad delivers a 2,000g magnetic hold to keep the phone locked in place, while a 5.9-ft cable adds slack for charging without unplugging.

ESR Xtend 45W Retractable Charger
The Xtend charger solves a smaller but familiar annoyance: the loose cable that always ends up tangled at the bottom of a bag. It has a cable built right into the block, one that pulls out to 3.1 ft when needed and retracts back in when it’s not. ESR says the braided cord can handle 20,000 pulls and 10,000 bends, which is a lot of trips through airport security.
Powered by the PD 3.2 AVS protocol, the Xtend charger delivers up to 60W of dynamic power, enough to fast-charge laptops, phones, and other smart devices without swapping bricks between them. ESR says it can push an iPhone 18 Pro to 50% in about 15 minutes, a pace that turns a quick coffee break into enough juice to get through the rest of the day without reaching for an outlet.
A second USB-C port sits tucked onto the side, so a set of earbuds or a smartwatch can top up alongside the phone without hunting for another outlet or unplugging anything else first. TÜV certification backs up the over-voltage, under-voltage, and temperature safeguards built into a charger small enough to disappear into a jacket pocket without adding any noticeable bulk. All these features are packed into a compact, travel-ready shell that’s easy to swap in for the bulkier charger-and-cable combo most people pack for a trip, making it especially convenient for travel and on-the-go use.
Seeing the iPhone Duo and the iPhone 18 Pro paired with accessories built around their actual design makes it easier to skip the usual guesswork of a phone setup. ESR treats the hinge, the screen, and the charging cable as design decisions rather than afterthoughts.
