Anker Prime 250W 27650 mAh versus UGREEN 25k 145W Power Banks

Summary

This video script reviews two high-capacity power banks, the Ugreen 145W and the Anker 250W Mega, assessing their charging capabilities and efficiency. The Ugreen, while advanced with multiple charging modes, struggles to maintain its high power output and has an inaccurate power meter. The Anker, boasting a 250W output, delivers impressive charging speeds but also has display inaccuracies. Both power banks offer good energy storage, but the Ugreen's UPS functionality and the Anker's efficiency make them notable, albeit with some flaws and high price tags.

Takeaways

• 🔋 The Ugreen power bank claims to provide 145 watts of power capability but struggles to sustain this output for long periods, likely due to overheating issues.
• 🔌 The Ugreen model 90597 A power bank features Power Delivery and Quick Charge capabilities on three ports, but lacks PPS modes, which may limit charging for certain devices.
• 🔍 The Ugreen power bank's user manual includes an infographic detailing port capabilities and power delivery, which is appreciated for clarity but lacks information on usable capacity.

What claims does the Ugreen power bank make about its power capabilities?

The Ugreen power bank claims to have a 145 watts power capability, with three total ports that can deliver various voltages and support both power delivery and Quick Charge capabilities.

What is the issue with the Ugreen power bank's power output as described in the script?

The Ugreen power bank has an issue with sustaining its high power output. It can only deliver 145 watts for a short period before one of the ports shuts down, likely due to overheating of the electronics rather than the battery.

What is the Anker power bank's main advantage according to the script?

The Anker power bank's main advantage is its efficiency and high power output capability, being able to charge at 140 watts for most of its charge cycle and having a low power loss from the wall to the output.

What is the issue with the power meter display on both power banks?

The power meter display on both power banks is inaccurate, showing 100% charge before the charging cycle is actually complete, which can mislead users about the actual charging status.

What is the UPS capability of the Ugreen power bank?

The Ugreen power bank has UPS (uninterruptible power supply) functionality, allowing it to keep the USB-C port operating during power outages on the other USB port, although it can still deplete itself as it allows more power to flow out than in.

What is the power density of the power banks discussed in the script?

The power density of the power banks indicates how fast the energy can be accessed. The more expensive power banks, like the Anker, stand out with higher power densities, meaning they can charge and discharge faster.

What are the physical dimensions and form factors of the Ugreen and Anker power banks?

The Ugreen power bank is described as a more typical long flat pack, while the Anker power bank is likened to a burrito due to its larger and heavier form factor, but also because it contains a larger battery capacity.

What is the script's final verdict on the Ugreen power bank's value for money?

The script suggests that the Ugreen power bank, while not necessarily bad, is overpriced considering its average efficiency and struggles to deliver on its power claims, making it less competitive compared to other high-end power banks.

What future content does the script mention for the channel?

The script mentions that the channel plans to review more power adapters, including some lower wattage ones from Europe, and that there is a long list of upcoming power banks and adapters to be tested.
