This review compares three 140W power banks: the Amagat, Bass, and Iniu, evaluating their performance against their advertised specifications and price points. We put each power bank through rigorous testing to assess their real-world capabilities, focusing on power output, battery life, and overall usability. Our findings reveal a significant disparity between the advertised features and the actual performance of these portable power solutions. We highlight both positive and negative aspects, providing readers with a comprehensive understanding to aid in informed purchasing decisions.This comparative analysis unveils a critical need for discerning consumers to scrutinize marketing claims. While all three power banks aim for a 140W output, none consistently met this target. We detail the specific shortcomings of each model, exploring issues such as inconsistent power delivery, inaccurate battery indicators, and overall reliability. Our goal is to empower consumers to make informed choices, emphasizing the importance of prioritizing reliable performance over enticing but misleading specifications.
Pros And Cons
- Moderate size with generous output modes.
- Includes USB cable and user manual.
- Has a low power mode.
- Reasonable thermal performance (didn't get externally too hot).
- Display accurately tracked charging progress.
- Met claimed efficiency at lower wattages (especially 50W).
- Good choice for mid-size devices.
- Performed well in terms of energy capacity versus rated energy.
- Can't sustain 140W output for full discharge; shuts down around 30% capacity.
- 140W rating is somewhat misleading.
- Charging time not as fast as it could be due to lack of faster charging support.
- Cheap
- Overheats.
- Only a 65W power bank falsely advertised as 140W.
- Suffered the same display issues as the Inu power bank.
- Fairly large capacity (maximum wat hours for airplane travel).
- Lots of USB modes and ports.
- Power pass-through functionality.
- Functions as an uninterruptible power supply (UPS).
- Okay efficiency at lower wattages.
- High energy capacity (can charge a 14-inch MacBook Pro multiple times).
- Poor display (inaccurate battery percentage, uses almost 2W).
- Cuts out early in tests.
- Cannot consistently supply 100W at 20V, maxes out at 135W.
- Fails to supply 140W at all.
- Power level reporting is inaccurate and causes the output to shut down completely until re-plugged into the wall.
- Overheats when attempting to use at 140W.

Amagat 140W Power Bank: A Budget-Friendly Disappointment
The Amagat 140W power bank, touted as a budget-friendly option, proved to be a letdown. Initial testing revealed significant issues, with the device failing to function correctly. This strongly suggests quality control problems within the manufacturing process.
While initially appearing promising due to its low price point, the Amagat's performance was far below expectations. The malfunctioning unit raised serious concerns about its reliability and overall value. Further testing was deemed unnecessary given the initial failures.
Bass 140W Power Bank: A Decent Performer with Limitations
The Bass 140W power bank offered a more positive experience compared to its counterpart. This power bank provided a better user experience, though it still fell short of its claimed 140W output. Despite these limitations, the Bass still provides solid performance.
The power bank's 24,000mAh battery capacity delivered decent runtime for mid-sized devices. It exhibited relatively good efficiency at lower wattages (50W), but performance dipped significantly at higher wattages (140W). Despite being smaller than the Inu it had a decent energy capacity compared to the Inu.
Iniu 140W Power Bank: A Major Letdown
The Iniu 140W power bank, despite its size and high advertised capacity, was deeply disappointing. It fell far short of its claimed 140W output, struggling even to reach 100W consistently. The inaccurate battery percentage display was another major issue.
Further compounding the problems, the Iniu exhibited inconsistent behavior, frequently cutting out and requiring a full restart to resume functionality. These issues significantly hampered its usability and overall performance. The advertised features, like pass-through charging and UPS functionality, were also unreliable.
Comparison and Conclusion
Comparing the three power banks, the Bass emerged as the most reliable, despite its limitations. It offered a better balance of capacity and performance than the Iniu and Amagat. However, even the Bass struggles to consistently deliver the advertised 140W output.
Ultimately, none of these power banks fully lived up to their 140W claims. The Bass was the best performer, offering decent capacity and efficiency at lower wattages. The Iniu, despite its large battery, fell considerably short in performance and usability. The Amagat was simply a malfunctioning unit, highlighting quality control issues. Consumers should temper expectations when purchasing high-wattage power banks.
Consider carefully your needs, and always check detailed reviews before committing to a purchase. Prioritize consistent performance and realistic wattage claims over misleading marketing and advertised specifications.
