• 🔋 Anchor’s new adapter has a unique feature: magnetic pogo pins for charging power banks directly, although its overall efficiency is lower than some competitors.
• 📉 The performance and efficiency of these adapters vary, but the Roasterin adapter stands out as particularly efficient, while the Avatronic is a value-focused option.
• 🔄 All the tested adapters renegotiate power when devices are plugged or unplugged, which is standard for this type of product.
• 📏 Voltage ripple and output voltages were well within acceptable ranges across all adapters, with no major performance issues observed.
• 💰 When comparing value, Avatronic provides the best balance of price and performance, while Anchor’s adapters offer fewer advantages for their cost.
• 📊 The video concludes that while there are no groundbreaking innovations, the Roasterin adapter is a standout, especially with its replaceable power cord, offering flexibility and performance.

Q & A

What is the primary goal of the video discussed in the transcript?

The primary goal of the video is to test and compare several 100-watt power adapters, including models from Nanami, Roavserin, Avatronic, and Anker, to determine their performance, features, and value in order to find the best power adapter.

Which specific models of power adapters are mentioned in the video for comparison?

The specific models mentioned are the Nanami 100W USB desktop fast charging station, Roavserin 100W desktop fast charger, Avatronic PD Pioneer 100W 4-port desktop charger, and Anker Multi-Device Fast Charging 100W Prime A1902.

What are some of the features common across the adapters tested in the video?

Common features include 5V, 9V, 12V, 15V, and 20V fixed USB 3.1 power delivery modes, programmable power supply (PPS) mode, safety listings, and energy efficiency compliance marks (such as DOE 6).

What is the benefit of having a removable power cord, as noted with some of the adapters?

The benefit of a removable power cord is that it allows users to easily swap in international power cords, making the adapters more versatile for use in different regions.

Which adapter is noted to have a special feature involving Pogo pins, and what does it do?

The Anker Multi-Device Fast Charging 100W Prime A1902 adapter has a special feature with Pogo pins that allow it to directly charge newer Anker power banks without the need for a cable, creating a wired connection through a strong magnetic attachment.

What is one of the performance metrics used to compare the adapters, and how do they rank?

One of the performance metrics used is idle power consumption. In this area, the Satechi 100W adapter has the best idle performance, while Anker's adapter is noted for having higher-than-normal idle power consumption, placing it lower in the ranking.

Which adapter was identified as having issues with power factor correction (PFC) and what impact does that have?

The Anker adapter was identified as having issues with power factor correction, particularly in lower voltage modes (5V, 9V, 12V). This results in it using extra power without PFC turned on, which affects its energy efficiency.

What was the performance of the Roavserin 100W desktop adapter compared to others?

The Roavserin adapter performed similarly to the Basus 100W adapter, with good efficiency, low idle power consumption, and solid overall performance. It stood out as a strong competitor in the 100W adapter market.

Why is the Avatronic adapter considered a good value option?

The Avatronic adapter is considered a good value option because, despite being less expensive than other models, it delivers solid performance and efficiency, making it an affordable choice without sacrificing much in quality.

How does the video describe the testing and safety of these adapters?

The video mentions that all the adapters underwent performance tests, including testing their power delivery modes, efficiency, voltage ripple, and overload protection. Safety listings such as DOE 6 marks were also checked to ensure compliance with energy efficiency standards.
