The Xtorm Titan Pro XB402 in the test, unique design meets 140W USB C port and 24,000 mAh

With the Titan Pro, Xtorm offers a new high-end power bank. What’s particularly exciting here are the 140W USB C ports. There is also a display with performance values ​​and a capacity of a good 24,000 mAh.

Sounds exciting! Let’s take a look at the Xtorm Titan Pro XB402 in the test! Can the power bank impress in the test even at the quite high price of around €200?

At this point, many thanks to Xtorm for providing the Titan Pro XB402 for this test.

Die Xtorm Titan Pro XB402 im Test

With a total output power of up to 150W and 24,000 mAh, the Xtorm Titan Pro XB402 is quite a powerful power bank.

Accordingly, it is slightly larger and heavier at 190 x 90 x 27.5 mm and a weight of 706g. Something may even be an understatement here: the power bank is quite large and heavy.

The feel and look are typically exceptional for Xtorm. This is not a run-of-the-mill power bank from a large Chinese manufacturer that is sold under X name. No, we have a unique design here, which I really like.

The power bank is also very well made and feels great.

Titan Pro ports, USB C only

The Xtorm Titan Pro XB402 has 4x USB C ports. I would almost say “unfortunately” here. USB C is of course important, but I would also like to see a classic USB A port on power banks. For example, I would have found 3x USB C and 1x USB A to be perfect.

However, I don’t want to complain too loudly here, USB C is THE standard. Especially when we have quite powerful ports like here.

USB C 1 / 2 – 140 W USB Power Delivery – 5V/3A, 9V/3A, 12V/3A, 15V/3A, 20V/5A, 28V/5A
USB C 3 / 4 – 30 W USB Power Delivery – 5V/3A, 9V/3A, 12V/2,5A, 15V/2A, 20V/1,5A

The two primary USB C ports offer a whopping 140W maximum power! Important, maximum performance, you can of course also charge smaller devices on these ports.

This makes it easy to charge an iPhone on these ports without causing any damage. But it is also easily possible to charge large devices such as notebooks with up to 140W.

The secondary ports are a little weaker at 30 W, but are sufficient for most smartphones and tablets.

The power bank can also be charged via the primary 140 W.

With cable

Excitingly, there is a short USB C to C cable embedded on the side of the power bank. This is not permanently connected to the power bank, but is held in the power bank by magnets. The cable also supports the full 140W.

With an exciting display

The Xtorm Titan Pro XB402 has a display that shows you the battery level in % as well as performance values ​​for each individual port.

This display is integrated completely invisibly under the surface of the power bank. So here we have a kind of small LED matrix which displays the values ​​accordingly.

The display is certainly not the most readable display, but the integration is very cool and can be described as unique.

PPS Range

I was a bit disappointed with the PPS range of the Xtorm Titan Pro XB402. So of course it supports PPS, but the size of the PPS stage is smaller than expected.

USB C 1 / 2 – 3.3 – 6V at up to 5A or 3.3 – 16V at up to 3A
USB C 3 / 4 – 3.3-11V at up to 3A

This means that despite the 140W ports, the power bank cannot charge a Samsung Galaxy S23 Ultra with more than 25W, for example. A pity!

However, if you are an Apple user, then this may not matter to you.

Constant 140W?

Many 140W and 100W power banks cannot consistently deliver full power. Depending on the battery level or temperature, these sometimes throttle down much earlier.

The Xtorm Titan Pro can deliver the full 140W 90% of capacity. Only for the last 10% does this, excitingly, throttle down to 36W.

The capacity

What about the capacity of the Xtorm Titan Pro XB402? Xtorm promises 24,000 mAh here. I was able to measure the following:

Who% Der Ha 5V/2A 70.16 18962 79% 9V/2A 74.99 20268 84% 20V/3A 80.09 21645 90% 20v/5A 80.82 21845 91% 28V/5A 64.19 17350 72%

The capacity of the power bank fluctuated for me from excellent to ok. At low load (5V/2A) and extremely high load (28V/5A), the capacity of 18962 mAh and 17350 mAh respectively was relatively low for a power bank with 24000 mAh.

At medium/high load (9V/2A, 20V/3A, 20V/5A), however, the capacity was a very good 21000+ mAh.

On average I was able to achieve a good 20014 mAh, which corresponds to 83% of the manufacturer’s specifications.

Info: In general, the capacity of power banks always refers to the capacity of the battery cells inside. However, discharging these cells is not 100% efficient as there is always some loss in the form of heat due to internal processes, voltage conversions, etc. I consider a value of 80-90% to be good to very good, with values ​​above 90% being rare and values ​​below 80% being unusual. It is also important to note that smartphones do not charge 100% efficiently. For example, if a smartphone has a 2000mAh battery, about 2600mAh will be needed for a full charge. However, this may vary depending on the model and charging method.

Ladetempo

Expected charging speed Apple iPads +++ Apple iPhones +++ Apple MacBooks +++ Google Pixel +++ Huawei smartphones + OnePlus smartphones + Realme smartphones + Samsung Galaxy smartphones (“S” series) ++ Windows notebooks (Dell XPS, ASUS etc.) +++ +++ = “perfect” maximum possible charging speed to be expected ++ = very high charging speed to be expected + = fast charging speed to be expected 0 = “standard” charging speed to be expected – = slow charging speed to be expected — = not compatible or only very limited

With an output power of 140W, the power bank is of course ideal for larger devices such as notebooks, tablets and game consoles such as the Steam Deck.

However, it is also no problem to charge devices such as smartphones etc. on the 140W ports. The power bank is also ideal for Apple iPhones and Google Pixel models.

Only Samsung smartphones would not necessarily be charged at full speed due to the PPS level, which only goes up to 3A. An S24 Ultra would only be charged with up to +- 26W on the power bank.

Load and unload at the same time

Simultaneous charging/discharging seems to be possible with the Xtorm Titan Pro, but with a maximum of 60W.

Charging time

The Xtorm Titan Pro XB402 can charge with up to 140W, according to the manufacturer. But what does it look like in practice?

In my test, the power bank was able to charge with up to 136 W (or 139 W for a short time), which is impressive!

So a load lasted from 0% to 100% around 1:14 hourswhich is quite fast!

Charging took +- 1:26 hours on a 100W charger and +- 2:08 hours on a 60W charger.

Charging efficiency

Finally, let’s talk about charging efficiency. So the ratio of energy that the power bank needs to be charged compared to the energy that we can use at the end.

The power bank needed around 100-103 Wh to charge, depending on the speed.

in the best case
in the worst case

140W
78%
68%

100W
81%
70%

60W
78%
67%

This results in good charging efficiency in the range 81% to 67%.

Conclusion

The Xtorm Titan Pro XB402 is a really cool power bank! I refer this to both the design and the technology.

The Titan Pro is not another run-of-the-mill power bank, but a truly unique design! For example, I have never seen the practical and quite detailed LED display before. In addition to the current charge level, this also shows you the input/output power.

The integrated cable can also be a lifesaver.

On the technical side, we have 140 W output power with corresponding USB C 3.1 ports. This makes the power bank not only ideal for smartphones and tablets, but also for large notebooks.

The power bank can also be charged with 140W (136W). A full charge is pleasantly quick at +- 1:14 hours.

The power bank can also largely deliver the full 140W power constantly. This only slows down for the last 10%.

The capacity of the power bank was also generally suitable with an average of 20,014 mAh and a maximum of 21,845 mAh.

But is there anything to criticize about the Xtorm Titan Pro? Yes, the PPS range is not optimal for the S23 Ultra and S24 Ultra. This means they cannot be charged with the full 45W.

But if you don’t have a Samsung smartphone and you want a somewhat unusual power bank, then the Xtorm Titan Pro is a great choice!
