Powerbank review of Rombica NEO PRO 440C at 44,000 mAh: charges everything

Written by Ahsan Kamal

And a smartphone, and tablets, and laptops – this device is suitable, it seems, for charging everything that has a battery. Our colleague Roman Zhukov shares his experience of operating superpowerbank.

I have had the idea of ​​acquiring a good power bank for a long time. I need it to solve the main problem: recharging the laptop. My laptop is old, the battery is already worn out, the processor load is always almost full. As a result, the autonomy of the device does not exceed 2 hours, which, you see, is far from the limit of dreams. 

Finding a suitable power bank at an affordable price was short: there are not many such devices today. It is understandable: for example, my model weighs more than a kilogram, and carrying such a thing with me is a pleasure below average. But there is nothing to be done: the higher the capacity, the more weight. So, I settled on the Rombica NEO PRO 440C, it cost me about 10,000 rubles. 

Design and Interfaces

Actually, like all power banks, the device is a rectangular metal case with rounded edges. The capacity of the lithium polymer battery is an impressive 44,000 mAh. At the same time, the kit includes as many as 28 adapters for almost all occasions. 

In addition to the port for connecting power, there are 2 USB-A, one USB-C and one more universal – just for connecting one of the many connectors. What is especially nice, there is support for Quick Charge 3.0, and even when charging two devices at the same time, the device provides a current of 3 A on each connector (at a voltage of 5 V). The cable included is only universal. 

Control as such is not required here – just one button, when pressed and held, turns on the power, with further presses it allows you to select the desired output voltage (up to 20 V). Next to the button is a small screen that displays the operating mode (voltage) and residual capacity in percent. It is very convenient, although there is a feeling that the “percentages” do not quite accurately reflect the state of the battery. 

Operating experience

On the whole, the device lived up to my expectations – indeed, it quickly charges the laptop, after fully charging my battery (2900 mAh) the power bank spends only 13% of its capacity from scratch. It doesn’t quite fit with math, but still. The case is durable, and despite the weight of the device, it’s convenient to hold it in your hands.

The kit comes with a soft cover – in principle, you can put there a power bank, a cable, and all the connectors. 

Disappointed only one nuance. There is such an organization as the Council of the International Civil Aviation Organization (ICAO). It is she who regulates the rules for the transport of lithium batteries, which are dangerous goods. It looks like this: 

  • up to 100 Wh are allowed for transportation in the cabin, 
  • from 100 to 160 Wh can also be transported if the policy of a specific carrier allows this
  • More than 160 Wh are prohibited for air travel.

In Rombica NEO PRO 440C – 162.8 Wh , so in fact I can not take it with me on a flight. If you fly often, consider this nuance when choosing a power bank.
