Belkin has launched the UltraCharge 10K 45W power bank in China, targeting users who prefer not to carry extra cables. This compact 10,000mAh battery pack features a built-in USB-C cable, an LED display showing exact charge percentage, and can deliver up to 45 watts of power. Priced at roughly $40 (269 yuan) on JD.com, it’s a neat all-in-one solution for on-the-go charging.
The device’s capacity is a familiar 10,000mAh, but the internal design is beefed up with two 5,000mAh cells totaling 36Wh-well within the 100Wh airline limit for carry-on batteries. At 231 grams and measuring 111 × 57.8 × 24.7 mm, it’s compact and portable. Buyers can choose from black, blue, or sand-colored finishes. The included USB-C cable is a no-frills 293mm length, suitable for both charging your phone and recharging the power bank itself.
Belkin UltraCharge 10K specs
- Capacity: 10,000 mAh / 36 Wh
- Ports: one built-in USB-C cable, one USB-C port, one USB-A port
- Max USB-C output: 45W
- Max USB-A output: 18W

- Supported charging standards: USB Power Delivery (PD) and Programmable Power Supply (PPS)
- Pass-through charging: up to 15W
- Display: LED indicator with precise battery percentage
The standout feature is the 45W USB-C output, making the UltraCharge 10K capable of powering not just smartphones and tablets but also lighter laptops like the MacBook Air-provided you’re not maxing out the device under heavy load. This wattage significantly surpasses the typical 20-30W output common to most 10,000mAh power banks still dominating e-commerce sites.
Charging multiple devices impacts output. Using two USB-C outputs simultaneously drops combined power to 24W, and maxing out all three outputs (including USB-A) caps total output at 22.5W. Essentially, this power bank excels when focused on a single main device rather than replacing a multi-port wall charger for several gadgets simultaneously.
To manage heat generated from this power density in a small chassis, Belkin incorporated Shield Pro technology, which uses two chips and NTC sensors that monitor temperature every 20 milliseconds. This attention to thermal protection aligns with similar safety features now standard in brands like Anker, Ugreen, and Baseus.
Other practical touches include the side-mounted LED display that provides a precise battery percentage rather than vague charge bars, helping users avoid surprises. Pass-through charging supports up to 15W, so you can charge the power bank itself while it powers a device-a convenient feature not always available on compact models.
The shell is made from 75% recycled plastic, and it ships in plastic-free packaging. This emphasis on sustainable materials parallels recent initiatives by major accessory brands like Logitech, Samsung, and Belkin itself, which have been highlighting eco-friendly production more prominently in recent years. Still, for many buyers, specs such as capacity, charging speed, and weight are the main decision drivers.
At around $40, the UltraCharge 10K slots into a competitive segment where 10,000mAh power banks with 45W USB-C charging typically range between $30 and $50. Its built-in cable and display add value. Earlier this year, Belkin also unveiled a magnetic 10K power bank with Qi 2.2 wireless charging, signaling a move toward pricier, feature-rich portable chargers.
Belkin’s UltraCharge 10K raises the bar for compact battery packs by combining high-watt charging, integrated cables, and clear charge readouts. The real question now is whether this design will push other brands to integrate built-in cables more broadly, or if users will stick with more traditional, cable-reliant models.
