The UGREEN 20000mAh 100W Power Bank (Model #25188) promises to revolutionize portable charging with its impressive 100W output and hefty 20000mAh capacity. But does it live up to the hype? After several weeks of rigorous testing, charging various devices, and putting it through its paces, here’s our comprehensive review.

This power bank is packed with features designed for modern mobile lifestyles. The standout is undoubtedly the 100W USB-C port, capable of rapidly charging even power-hungry laptops. The inclusion of two USB-C ports and a USB-A port allows for simultaneous charging of multiple devices. UGREEN also boasts its multi-protect safety system, encompassing overcharge, short-circuit, and temperature protection, which provides peace of mind.

The sleek, grey design is surprisingly compact for its capacity, making it easy to slip into a backpack or travel bag. The included 100W USB-C to USB-C cable is a welcome addition, though a 65W charger is not included and is required for optimal fast charging. The manual is clear and concise, making setup a breeze.

The 100W charging speed is genuinely impressive. I tested it with my MacBook Air, and the results were remarkable; it consistently charged significantly faster than my previous power bank. Simultaneous charging of multiple devices also performed well, without noticeably impacting charging speeds. The 1.5-hour recharge time (using a 65W charger, as specified) is a significant advantage, especially for frequent travelers.

Charging my iPhone 15 to 50% in under 30 minutes lived up to UGREEN’s claim. I also tested the power bank with several other devices such as an iPad Pro and a Galaxy S23 Ultra, all showing efficient and rapid charging times. I was particularly pleased with the battery life; it easily exceeded my expectation of three to four charges to my iPhone 15.

Pros:

• Blazing-fast 100W charging speed.
• Three simultaneous charging ports (two USB-C, one USB-A).
• Compact and lightweight design.
• Long battery life (20000mAh).
• Excellent build quality and robust safety features.

Cons:

• Requires a 65W charger for optimal fast charging (not included).
• Price point might be higher than some competitors.

The UGREEN 20000mAh 100W Power Bank (Model #25188) is a high-performance portable charger that lives up to its promises. The fast charging speeds, multiple ports, and impressive battery life make it ideal for power users and frequent travelers. While the price might be a consideration, the overall value and performance make it a worthwhile investment. I would highly recommend this power bank to anyone seeking a reliable and efficient portable charging solution.
