UGREEN Power Bank – Unveiling the Challenger:
First up, let’s take a closer look at the UGREEN 145W Power Bank (Model: 90597A). This power bank has generated significant anticipation and is finally making its debut on our website.
It boasts both Power Delivery and Quick Charge capabilities across three ports, offering voltage outputs of 5V, 9V, 12V, 15V, and 20V on the USB-C port, and 5V, 9V, and 12V on the USB-A port. However, it doesn’t support PPS (Programmable Power Supply) modes, limiting its compatibility with certain devices.
Performance Analysis:
The UGREEN power bank can deliver up to 145 watts of power, but our tests revealed that it struggles to maintain this level for an extended period. It reached only 70% of its rated capacity before shutting down, with the 100-watt port being the first to give in.
Surprisingly, the UGREEN power bank exhibited slower charging speeds, topping out at 60 watts, considering its high power output capabilities.
While it did charge moderately quickly, taking 1 hour and 42 minutes to reach a full charge, the power meter displayed inaccurate information, showing 100% well before the charging process was complete.
Efficiency-wise, it lost 21% of power at 50 watts output, placing it in the middle of the pack in terms of efficiency. Check out the latest prices here: Anker Prime Power Bank. and UGREEN 145W 25K.
Anker Power Bank – The Heavyweight Champion:
Now, let’s shift our focus to the Anker 250W Mega Ultra Power Bank. Anker has a reputation for quality and innovation in the power bank market. This model offers versatile voltage outputs, including 5V, 9V, 12V, 15V, 20V, and even 28V on the USB-C port, as well as 5V, 9V, and 12V on the USB-A port. It also supports PPS mode, enabling fast charging for compatible devices.
Performance Analysis:
The Anker power bank boasts impressive charging capabilities. It can maintain a 140-watt output for the majority of its charge cycle, allowing for rapid device charging.
Like the UGREEN power bank, the Anker also suffers from an inaccurate power meter display, showing 100% well before the charging process is actually complete.
Anker provides Bluetooth connectivity and app support, although privacy-conscious users may have reservations about using these features.
Efficiency-wise, the Anker power bank stands out, with only a 19% power loss when converting energy from the wall to portable power.

Comparing Density and Size:
Both power banks exhibit differences in terms of size and weight. The UGREEN power bank weighs in at 506 grams, while the Anker is bulkier at 663 grams. However, the Anker’s larger size accommodates its larger battery capacity.
Power Density Analysis:
The power density chart reveals that both power banks are among the top performers, offering high energy and power densities. This means they can charge and discharge quickly, making them ideal for users who need rapid power delivery.
Battery Density Analysis:
In terms of battery density, both power banks offer good energy storage relative to their size and weight. This means they can store a considerable amount of energy in a relatively compact form factor.
Other Considerations:
Both power banks come with unique features, such as a low-power mode that allows for extended charging of low-power devices. Additionally, they can charge slowly even with a basic 5W USB-A charger.
Furthermore, the UGREEN power bank exhibits limited uninterruptible power supply (UPS) capabilities, allowing the USB-C port to continue functioning during power outages. However, it’s worth noting that it can still deplete itself if not managed properly. The Anker power bank, on the other hand, doesn’t offer UPS functionality.
Thermal Performance:
Both power banks exhibited reasonable thermal performance, getting warm during use but not excessively hot. However, the UGREEN power bank developed some hot spots during high-output use. Check out the latest prices here: Anker Prime Power Bank. and UGREEN 145W 25K.
