In today’s fast-paced world, staying connected is essential, and having a reliable portable charger for your smartphone can make all the difference. The iWALK USB-C Portable Charger for iPhone 15/16 aims to keep your devices powered up wherever you go. Designed specifically for Apple’s latest iPhone models — including the 15, 16, and their various Plus and Pro versions — this compact, wireless power bank promises fast charging performance wrapped in a travel-friendly package. But does it live up to its claims? Let’s dive deeper into what the iWALK USB-C Portable Charger offers.
Key Features
Fast 20W Charging with USB-C PD Support
One of the standout features of the iWALK USB-C Portable Charger is its USB-C port supporting Power Delivery (PD) fast charging at 18W input. Thanks to this, the power bank itself can be fully recharged in just 1.5 hours, allowing you to quickly prep it for your next outing. On the output side, it delivers up to 20W, making it capable of fast charging compatible devices like the iPhone 15 series and many Android models, including Samsung smartphones.
Wireless Capability and Earbud Compatibility
Beyond wired charging, the iWALK power bank supports wireless charging for devices that allow it, adding an extra layer of convenience. Moreover, it can charge earbuds safely by delivering a lower current to protect delicate batteries, making it a versatile companion for various gadgets.
Pass-Through Charging Technology
A feature that sets this power bank apart is pass-through technology, which enables it to charge your smartphone while the power bank itself is plugged in and recharging. This is particularly useful in situations where you have only one available power outlet but need to power both your phone and the charger.
Portable and Travel-Friendly Design
At a capacity of 4,800mAh, the iWALK charger balances power and portability. It’s compact enough to fit comfortably in a pocket or small bag, making it ideal for on-the-go power needs without the bulk of larger batteries.

Additional Insights on Usage
The iWALK charger experiences an expected energy loss of 20% to 35%, meaning the usable capacity when charging your devices ranges between 2,880mAh to 3,500mAh. Users may also notice the charger becoming warm when the battery is under 30% charge, which is normal due to increased power draw. The manufacturer provides a handy formula to estimate the number of charges your device can receive:
(Power Bank Capacity × 0.66) ÷ Device Battery Capacity ≈ Number of Charges.
