30000 mAh Power Bank 3 (PB3018ZM) Review: Fast Charging Power Bank Test

The 30000 mAh Power Bank 3 (PB3018ZM) promises impressive fast-charging capabilities and the ability to power multiple devices simultaneously. But does it deliver on its claims? I’ve put this power bank through its paces over the past few weeks, subjecting it to rigorous testing to determine its real-world performance. This review will delve into its features, performance, and overall value.

This power bank boasts several key features designed for convenience and efficiency. The standout feature is undoubtedly the 18W fast charging output via USB-C, significantly reducing charging times compared to standard 5W chargers. The inclusion of two USB-A ports alongside the USB-C port allows for simultaneous charging of three devices. The 24W input via USB-C further streamlines the recharging process, meaning you spend less time plugged in. The low-current charging mode is a welcome addition, perfect for charging delicate devices such as Bluetooth headsets and smartwatches.

In my testing, the 18W fast charging lived up to its promise. Charging my iPhone 11 was noticeably faster than with a standard charger. The ability to charge three devices simultaneously was also a boon, allowing me to charge my phone, smartwatch, and headphones concurrently without significant performance degradation. The 24W input was equally impressive; charging the power bank itself was considerably faster than expected. The low-current mode worked flawlessly with my Bluetooth earbuds, ensuring a safe and efficient charge. During extended use, the power bank remained relatively cool, a testament to its efficient thermal management.

However, I did notice some minor inconsistencies. While the claimed 54% and 75% charging time reductions seem accurate under ideal conditions (using the recommended chargers), using lower-wattage chargers naturally resulted in longer charging times.

Pros:

  • Fast 18W charging via USB-C
  • Simultaneous charging of three devices
  • Fast 24W input charging
  • Low-current charging mode
  • High capacity (30000 mAh)

Cons:

  • Charging time reductions are dependent on the use of the recommended high-wattage chargers.
  • The included cable is not specified, so purchasing an appropriate cable is important.

Overall, the 30000 mAh Power Bank 3 (PB3018ZM) is a compelling portable power solution. Its fast charging capabilities, multi-device charging support, and efficient design make it a valuable asset for anyone who needs reliable power on the go. While the charging time claims are contingent on using high-wattage chargers, its performance is still significantly faster than many comparable power banks. I would happily recommend this power bank to anyone looking for a high-capacity, fast-charging option.
