Belkin has added a new twist to the crowded 10,000mAh power bank segment with a model that combines a built-in USB-C cable, 45W output, and a digital battery readout. The UltraCharge 10K 45W Power Bank is aimed at users who want faster top-ups without carrying extra cables.
The device is now on sale in China through JD.com for 269 yuan, with color options including Black, Blue, and Sand. Belkin positions it as a portable charging solution for smartphones, tablets, and even some lightweight laptops.
Two USB-C paths and one USB-A port
The UltraCharge 10K 45W uses a 2C+1A setup, giving users a built-in USB-C cable, a standard USB-C port, and a USB-A port. Both USB-C charging paths support up to 45W output through USB Power Delivery, while the USB-A port tops out at 18W.
The integrated USB-C cable measures 293 mm, which should make it convenient for short charging sessions on the move. Belkin also includes PPS support, expanding compatibility with devices that benefit from programmable fast charging.

More useful for one device at a time
Belkin says power sharing changes when multiple outputs are used together. If both USB-C connections are active at the same time, total combined output is limited to 24W.
When all three outputs are used together, the shared output drops to 22.5W. That makes the power bank best suited for quick charging a primary device first, rather than pushing maximum power to several gadgets at once.
The model also supports 15W pass-through charging, allowing it to recharge from a wall adapter while still sending power to another connected device. That adds flexibility for users who want to keep both the power bank and a phone topped up from a single outlet.
Accurate battery status and thermal protection
A standout feature is the LED display, which shows remaining battery as a percentage instead of relying on basic indicator lights. For users juggling multiple devices, that more precise readout can make it easier to judge when a recharge is needed.
Belkin has also built in dual-chip Shield Pro protection paired with an NTC temperature sensor that checks heat levels every 20 milliseconds. The company says this setup is designed to help prevent overheating and overcharging during fast-charge use.
Portable build with a sustainability angle
Inside, the power bank uses two 5,000mAh cells arranged in series. Despite the higher-output feature set, it remains relatively compact at 111 x 57.8 x 24.7 mm and weighs 231 grams.
Belkin says the outer shell is made from 75% post-consumer recycled plastic, and the retail packaging is completely plastic-free. The battery has also met 3C certification requirements and is approved for carry-on airline use.
Those details make the UltraCharge 10K 45W a practical option for travelers and daily commuters who need a compact charger with clearer battery status. It also arrives as Belkin broadens its 10,000mAh lineup, following another recent magnetic 10K model with Qi2.2 wireless charging and a built-in display.
