  "account": "For years, portable power banks have been a hot topic among smartphone users, but they've often been criticized for their slow charging speeds and tendency to overheat. With the introduction of Qi2.2 charging, these devices now charge more quickly, yet the heat issue lingers. It wasn't until I stumbled upon a liquid-cooled power bank that I could determine if this technology was merely a gimmick or if it truly made a difference when using the Google Pixel 11 Pro.\n\nInitially, wireless power banks were a hit-and-miss experience for me. They frequently heated up, resulting in throttled performance on my phone, which was often unusable. More importantly, this heat caused battery degradation, which was a deal-breaker for me. I eventually abandoned wireless chargers in favor of regular power banks until the launch of the new Pixel 11 Pro. This device supports Qi2 charging, prompting me to give wireless charging another try with the UGREEN MagFlow Pro power bank.\n\nWhat set this power bank apart was its liquid-cooling technology. The 10,000mAh power bank uses a micro-pump and coolant channels to dissipate heat during wireless charging. Essentially, the pump circulates coolant alongside a copper vapor chamber, which helps keep the power bank's internals cool. UGREEN claimed that this method pulls heat away from the wireless coil and maintains higher output. Interestingly, the company demonstrated an animation inspired by The Matrix's opening sequence to showcase the coolant's action within the power bank.\n\nAfter using the UGREEN MagFlow Pro for a month, I was impressed by its ability to keep both the power bank and the Pixel 11 Pro relatively cool. My temperature readings ranged from 91.94 to 96.8°F, which was much better than the 104 to 106°F readings I got with a competing Xiaomi Qi2.2 power bank. Not only did this cooler performance benefit my wireless charging experience, but it also seemed to reduce thermal throttling and maintain faster charging speeds.\n\nThe UGREEN MagFlow Pro also delivered a more consistent power output, providing about 13% more battery backup for the Pixel 11 Pro than the Xiaomi power bank. While the charging times were similar, the liquid-cooled power bank's ability to maintain cooler temperatures made a significant difference in the long run. Traditional power banks may not fare as well, and adopting some form of liquid cooling could be the key to improving their performance and extending battery life.",
