The iPhone 17 series pushes forward with powerful displays, enhanced cameras, always-on features and more connected tasks, all of which demand reliable battery backup when you’re away from power. A well-chosen portable charger can mean the difference between scrambling for an outlet and staying fully functional through long days, travel, or heavy usage. Four models stand out among current options: the Lisen Ultra Slim, Haiara, Chusii, and Torras MiniMag. Below is an exploration of each—including strengths, trade-offs, and what to prioritize when pairing with one of the iPhone 17 models.
1. Lisen Ultra Slim Portable Charger
The Lisen Ultra Slim charger is designed for those who prioritize portability above almost everything. With a relatively modest capacity, it packs enough power for one or one-and-a-half full charges for the average model in the iPhone 17 lineup, while remaining thin enough to slip easily into a pocket or attach magnetically without adding bulk. Featuring a 5,000mAh capacity, this MagSafe charger provides reliable power for meetings, travel, or daily adventures without adding bulk. Its ultra-thin design snaps on effortlessly, offering convenient charging for commuting, classes, trips, photo sessions, parties, or concerts. With advanced lithium-polymer technology and NTC temperature control, it delivers a full charge in just two hours—twice as fast as many standard portable chargers. The trade-off for its slim profile is that it cannot contain as much capacity as larger power banks; during long trips or in situations of heavy usage, more frequent recharging of the charger itself may be necessary. Still, for daily carry, commutes, or topping up throughout the day, the Lisen Ultra Slim offers an elegant and lightweight solution for the iPhone 17 series.
2. Haiara Portable Charger
The Haiara charger leans toward a middle ground between portability and 10000 MAH capacity. It delivers more stored energy than ultra-slim models, enabling multiple full charges for most of the iPhone 17 variants, and includes both wireless magnetic charging and fast wired options, typically via USB-C with Power Delivery. The magnetic alignment is stronger to ensure steady wireless contact even during movement. Battery indicators allow users to see how much stored power remains, and safety circuits guard against overheating, overvoltage, and other electrical issues. The size and weight are greater than ultra-slim types, meaning it may not slide into tight pockets or cling as neatly to magnetic attachment surfaces. For users who expect heavier usage—travel, field work, long days away from outlets—the Haiara strikes a useful compromise, offering more endurance while still retaining enough portability for casual carry.
3. Chusii Portable Charger
Chusii is aimed at those who want maximum versatility and 12000 mAh capacity in a portable charger. This model tends to offer higher power output, multiple ports (wired and wireless), and a larger battery capacity that supports the demands of long travel, heavy phone usage, or multiple device charging. Strong magnetic alignment with 1,400 grams of holding force ensures your iPhone locks into place instantly and stays firmly secured. In just a second, it snaps on and is ready to charge, making this wireless power bank a perfect solution for cutting down on cable clutter and avoiding the hassle of plugging and unplugging cords. Once attached, the battery pack is automatically recognized by your phone and begins charging wirelessly, removing the inconvenience of loose connectors. By freeing you from wall outlets and tangled wires, it delivers a seamless charging experience and lets you enjoy uninterrupted gaming or other activities. The larger capacity and additional features also bring size and weight penalties, making the charger less ideal for extremely light carry or for attaching magnetically in delicate setups. Still, for power users of the iPhone 17 series who demand more battery headroom, the Chusii model offers a strong capability and flexibility profile.
4. Torras MiniMag Portable Charger
Torras MiniMag aims to merge magnetic wireless convenience with a compact and well-balanced capacity. It delivers enough power to reliably top up the iPhone 17 in most day-long scenarios while maintaining a modest thickness and footprint. The Torras MiniMag power bank, with its 10,000mAh capacity, is one of the slimmest and lightest options available, making it ideal for users who are always on the move. Despite its compact profile, it delivers ample power to keep devices charged throughout the day. Designed with strong magnetic attraction, it attaches effortlessly to your phone for cable-free charging, eliminating the hassle of wires. Its portability and ease of use make it highly practical, and with MagSafe compatibility, it works seamlessly with a wide range of magnetic phone cases. Even though its capacity is less than bulkier banks, its design emphasis is on balance: enough power to cover heavy usage days, but still portable enough to be carried daily without significant burden. For users who value magnetic convenience, consistency, and a good blend of power vs portability, the Torras MiniMag represents a well-rounded option.
