Ripple&noise Anker Zolo 140W

Anker Zolo 140W (A2697) Ripple/Noise Test

The video tests the charger’s output ripple and noise across several voltage and load settings.

Measurements Reported

• 5V: 19.6 mV at no load; 27.6 mV at 3A
• 9V: 19.2 mV at no load; 24.4 mV at 3A
• 15V: 22.4 mV at no load; 37.6 mV at 3A
• 20V: 21.6 mV at no load; 33.2 mV at 5A
• 28V: The subtitle reports 211.6 mV at no load and 34.8 mV at 5A. The no-load figure is unusually high compared with the other readings and may reflect a transcription or measurement ambiguity.

Main Points

• The reviewer describes the charger’s noise as very low.
• At 20V/5A, the ripple waveform is described as even, with a low 33.2 mV reading.
• At 28V/5A, the waveform is said to look similar to the 20V result.
• The reviewer’s overall assessment is that the loaded measurements are very good, with readings below 50 mV.

Pros and Cons

• Pros: Low ripple/noise under the tested loads; smooth, even-looking waveforms.
• Cons: No clear product drawbacks are discussed. The reported 28V no-load reading is an outlier and is not explained.

Verdict

The reviewer gives the Anker Zolo 140W a positive assessment for ripple and noise performance under load. No ratings or direct comparisons with other chargers are provided; the comparisons are between the charger’s own voltage and load settings.
