Belkin UltraCharge Slim Magnetic Power Bank 10K Features
Ultra-Slim Design Built for Everyday Carry
One of the biggest highlights of the new power bank is its slim profile. Measuring just 10.6mm thick, the device is designed to slide easily into pockets, handbags, or backpacks.
The soft silicone finish provides a comfortable grip, while the aluminum alloy shell adds durability and a premium appearance. The magnetic attachment ensures that compatible smartphones remain securely connected during charging.
The ergonomic design also helps reduce slipping while holding the phone and power bank together.
Qi2 Wireless Charging Support

Belkin has equipped the UltraCharge Slim with Qi2 wireless charging technology that delivers up to 25W charging speeds. This allows supported smartphones to recharge more quickly compared to standard wireless chargers.
The magnetic alignment ensures proper positioning between the power bank and the smartphone, improving charging efficiency and convenience.
Users can simply attach the power bank to the back of their compatible device and continue using the phone while charging.
Charge Two Devices Simultaneously
Another major advantage of the new power bank is dual-device charging support.
The wireless charging pad can provide up to 25W output, while the USB-C port delivers up to 30W charging speeds. This means users can charge a smartphone wirelessly while simultaneously charging earbuds, tablets, gaming devices, or another phone through the USB-C port.
The 30W USB-C port also supports pass-through charging, allowing the power bank itself to recharge while charging connected devices.
Up to 44 Hours of Extra Battery Life
Belkin claims that the 10,000mAh battery can deliver up to 44 additional hours of video playback for an iPhone 17 Pro. This makes the accessory particularly useful during long trips, flights, business travel, or extended outdoor activities.
The battery pack comes pre-charged out of the box, allowing users to begin using it immediately without waiting for an initial charge.
Enhanced Safety Protection
Safety remains an important focus for Belkin. The company includes its SmartProtect technology, which reportedly undergoes 55 separate safety tests.
The dual-chip protection system helps guard against overheating, overvoltage, and other charging-related issues. These features are designed to protect both the power bank and connected devices during charging sessions.
Travel-Friendly Design
The UltraCharge Slim has been designed with travelers in mind. It meets TSA carry-on requirements, making it suitable for air travel.
Its compact dimensions and lightweight construction allow users to carry it comfortably without adding significant bulk to their luggage or everyday carry setup.
