ZDNET's key takeaways


It's hard to come across a power bank that impresses me anymore. Most are mundane plastic enclosures with a few ports. However, the Cuktech P-series 25,000mAh power bank is a game-changer. This power bank's stylish design and advanced technology pushes the envelope of what a power bank can achieve.

After using it on a week-long trip away from home, I was amazed by its durability. Everything about the P-series power bank feels premium and stylish; from the packaging to the design. There's even a futuristic pulsing blue light on the front that appears when the power bank is in use -- making it look like something out of a sci-fi film. 

OK, enough about the look and feel; let's get into the specifics. There are certain metrics that I test as a matter of course for every power bank. The first is capacity. Testing this involves discharging and fully charging the power bank several times while it is connected to a USB meter. No problems on this score with this power bank.

The same goes for the inputs and outputs of the USB ports. Moreover, it's common to encounter manufacturers who overestimate the capabilities of their products. Also, I've come across a lot of power banks that can hit the rated outputs but falter when they are kept at that level for extended periods. Again, this power bank passed these tests with no concerns. 

Finally, let's talk about safety. It's shocking how many power banks still get hot to the point of being dangerous when pushed hard for prolonged periods. The P-series power bank showed none of these issues, often staying cool even when pushing out the maximum 210W of power.

I must admit that my inner geek loves the TFT display on this power bank. It displays important -- at least to me! -- information such as battery level, power, voltage, and current. A tap of the button brings up a graphical display of the input and output wattages.

I love having this information at my fingertips because it transforms the unit from being a generic power bank into a full-blown charging computer, and this is handy for someone like me who uses USB meters to test devices.

Need to trickle-charge something? No problem! Just double-tap the button to put the unit into low-current mode. 

ZDNET's buying advice

The Cuktech P-series 25,000mAh power bank is one of my favorite power banks. From a technical standpoint, everything about this unit is top-notch, from the fit and finish to the modern, sci-fi look and the tech built on the inside. 

Beyond the bulk -- and every 25,000mAh power bank is going to be bulky -- and I admire the fact that the finish picks up and shows every speck of dust, I honestly can't fault this product. Currently, it's going for $99, an unbeatable value.
