The P502 50000mAh power bank (model number 1131000041) promises a massive charge capacity combined with fast-charging capabilities. I’ve spent the last few weeks putting it through its paces, subjecting it to various charging scenarios and devices. This review details my experiences, both positive and negative, to help you determine if this behemoth is right for you.

The P502 boasts an impressive array of features. Beyond its sheer capacity, the 22.5W output is a definite highlight, allowing for reasonably quick charging of compatible devices. The inclusion of multiple ports – Type-C, Micro USB, and four USB ports – ensures compatibility with a wide range of devices. The LED display is a welcome addition, providing a clear visual indication of the remaining battery life. The build quality feels surprisingly solid for a power bank of this size. The matte finish helps with grip and prevents it from feeling overly slippery.

In real-world testing, the P502 consistently delivered on its promises. I managed to fully charge my iPhone 13 Pro Max approximately four times from a single charge. Charging the power bank itself took a considerable amount of time, around 8-10 hours using a 20W charger, but the longevity of the charge more than makes up for this. The fast-charging feature worked well, noticeably reducing charging times for my phone compared to using a standard 5W charger. I also tested the power bank with my iPad Pro and laptop, both achieving respectable charging speeds. However, it’s worth noting that the actual charging speed will vary depending on the device and its charging capabilities.

The safety features seem robust, I experienced no issues with overcharging or overheating during my testing. The on/off switch is a practical inclusion, preventing accidental discharge when not in use.

Pros:

• Massive 50000mAh capacity
• Fast 22.5W charging
• Multiple charging ports (Type-C, Micro USB, 4 USB-A)
• Clear LED display
• Solid build quality
• Effective safety features

Cons:

• Relatively long charging time for the power bank itself
• Quite heavy and bulky

The P502 50000mAh power bank is a powerful and versatile device, ideal for those who need a reliable power source on the go, especially during long trips or in situations where access to power outlets is limited. While the long self-charging time and weight are drawbacks, the massive capacity and fast charging capabilities significantly outweigh these inconveniences for many users. I’d confidently recommend the P502 to anyone looking for a high-capacity power bank that can reliably power multiple devices over several days.
