SUPERONE Retractable iPhone Charger 4-Port USB C Charger Block - Long

In this review the SUPERONE Retractable iPhone Charger stands out as a travel-friendly 4-in-1 wall charger for people who need fast, clutter-free charging for multiple devices. The single biggest reason to buy is its built-in dual retractable USB-C cables that extend up to 35.4 in, removing the need to pack separate cables while letting you charge devices comfortably away from the outlet. The review focuses on real-world use for phones, tablets and accessories and evaluates speed, safety and portability rather than marketing claims.

Key Features

• Dual retractable cables: The two built-in USB-C cables extend to 35.4 in so devices can be used while charging without tangled cords.
• 4-in-1 charging: Four ports deliver a combined output up to 78W so up to four devices can charge at once for fewer adapters on a trip.
• Fast charging support: Each USB-C output and the dedicated USB-C port can supply up to 20W while the USB-A port supplies 18W, enabling much faster top-ups than low-power chargers.
• GaN 6 safety: Modern GaN technology with multi-layer protection guards against overcharging, overcurrent and overheating for safer daily use.
• Travel design: Compact block with a foldable plug, rounded edges and global voltage compatibility (100-240V) makes it easy to pack and use internationally with the right plug adapter.

Who It's For

The charger is best for travelers, commuters and households that want to power multiple devices without carrying separate cables and bricks; its retractable cables and foldable plug reduce bag clutter while providing fast charging for phones, tablets and earbuds. It's particularly useful for owners of modern phones and tablets that accept USB-C fast charging, and for families who need to charge several devices simultaneously from a single outlet.

Those who should look elsewhere include users who need built-in device-specific connectors other than USB-C or anyone preferring a permanently attached long cable without retracting mechanisms. Also, customers seeking a dedicated ultra-high-watt single-port desktop charger for demanding laptops should consider larger GaN chargers instead.

Pros & Cons

Pros
