The Thunder 80 Power Bank (GNTHU80KPBBK) promises an enormous 80000mAh capacity, a suite of charging ports, and even a built-in flashlight. But does this behemoth deliver on its lofty claims, or is it just a lot of bulk? After weeks of rigorous testing, here’s my in-depth review.

This power bank boasts a truly impressive array of features. The massive 80000mAh battery is the clear standout, but it’s complemented by four USB-A ports and a single USB-C port, offering ample charging options for multiple devices simultaneously. The inclusion of a bright LED flashlight is a welcome bonus, proving surprisingly useful in various situations. The LED digital display is easy to read and keeps you informed of the remaining battery level. The ability to charge via USB-C, Lightning, or Micro-USB cables adds to its versatility.

In terms of performance, the Thunder 80 lived up to its potential, mostly. I charged a variety of devices, including smartphones, tablets, and even a portable Bluetooth speaker, multiple times from a single charge of the power bank. The fast charging capabilities (20W PD USB-C and QC 22.5W max USB-A) are noticeable, noticeably faster than many lower-wattage power banks. However, charging the Thunder 80 itself takes a considerable amount of time – expect a full recharge to take upwards of 10 hours, depending on your charger. The flashlight proved quite robust, and the digital display is a handy feature.

I did experience some slight inconsistencies in charging speeds across the different ports which is disappointing for a device at this price point and with such specifications. Some devices charged reliably faster than others, regardless of the port used. Some minor heat generation was noticeable during heavy use.

Pros:

• Massive 80000mAh battery capacity
• Multiple charging ports (4x USB-A, 1x USB-C)
• Fast charging capabilities (PD 20W and QC 22.5W)
• Bright integrated flashlight
• Clear LED digital display
• Multiple input options (USB-C, Lightning, Micro-USB)

Cons:

• Long charging time
• Slight inconsistencies in charging speeds across ports
• Noticeable heat generation during extended use
• Bulky size and weight

The Thunder 80 Power Bank (GNTHU80KPBBK) is a powerful device with impressive capacity and multiple charging options. While the long charging time and minor inconsistencies are drawbacks, the sheer amount of power it provides and its versatility makes it a worthwhile investment for anyone needing a reliable and high-capacity portable charger. For those who prioritize long-lasting power and don’t mind the bulk, I highly recommend it. However, users expecting blazing-fast charging across all ports and who prioritize compact size may want to explore other options.
