Comparing Wattage and Capacity Specs
Max Output Wattage
The UGREEN Nexode delivers a maximum output of 145W, supporting PD3.1 and QC3.0 standards. This high wattage allows it to power a 16-inch MacBook Pro from 0 to 56 percent in 30 minutes using a single USB-C1 port. In contrast, the INIU model provides a maximum output of 22.5W. This lower wattage is designed for faster smartphone charging, such as reaching 70 percent on a Samsung S25 in 25 minutes. The UGREEN unit offers significantly higher power for laptops, while the INIU unit is sufficient for mobile devices.
Battery Capacity
Capacity determines how many times you can recharge your devices. The UGREEN Nexode features a 25,000mAh battery, which can fully recharge laptops up to 1.3 times and mobile devices up to 5.2 times. The INIU model has a 20,000mAh capacity, providing approximately four full phone charges. The UGREEN unit holds 5,000mAh more energy than the INIU model. This extra capacity allows for more recharge cycles or powering higher-drain devices like laptops for longer periods before the power bank itself needs recharging.
Physical Dimensions
Size affects portability and pocketability. The INIU model measures 4.1 inches in width, 2.8 inches in length, and 1.2 inches in height. It is described as mini size and fits easily in a pocket. The UGREEN Nexode measures 6.3 inches in length, 3.18 inches in width, and 1.05 inches in height. The UGREEN unit is longer and wider, making it less pocket-friendly. The INIU model is more compact in overall footprint, prioritizing small form factor over maximum power density.
Weight
Weight impacts how comfortable the device is to carry during travel. The INIU portable charger weighs 11.1 ounces. The UGREEN Nexode weighs 1.11 pounds, which converts to approximately 17.76 ounces. The INIU model is significantly lighter, making it easier to carry in a bag or pocket for extended periods. The UGREEN unit is heavier due to its larger battery and higher power components. For users prioritizing minimal weight, the INIU model is the clear choice.
Recharging Speed
How quickly the power bank itself refills matters for daily use. The UGREEN Nexode supports two-way fast recharge, allowing it to fully recharge in just 2 hours when using a 65W PD charger. The INIU model data does not specify its input wattage or total recharge time. Without this data, we cannot compare the refill speed directly. However, the UGREEN unit explicitly supports rapid recharging with high-wattage adapters, ensuring you spend less time waiting for the power bank to fill up again.
