Belkin expanded its portfolio of portable charging products with its new model called UltraCharge Pro Laptop Power Bank 25K. This new powerbank, especially targeting laptop users, stands out with its 25,000 mAh capacity, output power reaching 140W and internal USB-C cable. The product was first offered for sale in the Chinese market and started to be listed on JD.com with a price tag of 529 yuan (approximately 3,610 TL). The model, which targets users who need a high-capacity energy storage solution, also draws attention with its structure that reduces the need to carry additional cables.
While the 25,000 mAh capacity offers a significant additional usage time for current laptops, it remains within the limits that can be carried under the hand luggage rules of international airlines. The dimensions of the device are announced as 89 x 26 x 164 mm, and its weight is 581 grams. The rounded lines preferred in the body design enable the product to be carried more easily in the bag. In addition, the battery level and charging status can be monitored instantly thanks to the LED screen on the front. Belkin offers the product in three different color options: black, white and sand.
The internal braided USB-C cable is among the highlights of the UltraCharge Pro 25K. Users can thus directly charge their phones, tablets or laptops without carrying a separate cable with them. To counter any questions that may arise about the longevity of the internal cables, Belkin states that the cable has gone through more than 3,500 bending and 10,000 plugging and unplugging cycles. In addition, the device also has a USB-C and a USB-A port. Thus, the powerbank can charge three different devices at the same time.
Belkin UltraCharge Pro 25K targets laptops with high output power
On the charging performance side, UltraCharge Pro 25K can provide up to 140W power output when used alone via the internal USB-C cable or USB-C port. The maximum output of the USB-A port is limited to 18W. When multiple devices are connected, the product dynamically manages the voltage using AVS (Adjustable Voltage Supply) and PPS fast charging protocols. This structure aims to keep heating under control while helping to distribute energy more efficiently.
If three outputs are used together, the total power capacity can reach 158W. In the scenario where two devices are connected, 140W output can be achieved via USB-C and 18W via USB-A. When all connections are active, two USB-C outputs provide 70 watts of power each, while the USB-A connection continues to provide 18W. These values allow simultaneous charging of high-performance laptops as well as tablets and smartphones.
90W USB-C input support is offered to recharge the power bank’s own battery. In this way, the charging time of the 25,000 mAh battery is significantly shortened. According to the data shared by Belkin, when the 140W output of the product is used, the 14-inch MacBook Pro (M5 Pro) model can reach a 50 percent charge level in approximately 28 minutes. Although actual usage results may vary depending on the device and usage conditions, the announced values reveal the high power transfer capacity of the product.
On the security side, there are various measures such as double smart protection chip, real-time temperature monitoring system, overcurrent and overvoltage protections. The body structure made of flame retardant material also supports safety features. In addition to China’s mandatory 3C certification, the product also has international certifications such as CE, KC and PSE.
Recently, the number of high capacity and high power models in the portable energy products category has been increasing. Recently, Cuktech introduced a new powerbank model with a capacity of 20,000 mAh that offers a dual internal USB-C cable, LED screen and 55W fast charging support. Belkin’s UltraCharge Pro 25K model appeals especially to laptop users with its higher capacity and 140W output power. However, due to its weight of 581 grams, it stands out as a more suitable option for users who focus on long-term mobile use rather than daily portability.
