Powerbank Comparison Table

 

Power bank usage recommendations

 

Below we have presented a summary table comparing the capabilities of the trust banks from our review under various conditions.

 

Summary table of power bank capabilities

 

• Power bank chargingability of laptops: Indicates that the power bank supports the USB-C Power Delivery 20V / 45W / 65W / 100W protocol and will be able to charge the laptop battery when it ‘falls asleep’, or extend the operating time of a laptop running on its own battery.
• Power bank chargingability ofpower banks: Indicates that the power bank supports the necessary protocols (Power Delivery, PPS), which allow the laptop to receive power stably and not turn off. Models with a capacity of 65 W and above are usually better suited for this. Such power banks allow laptops to work even on a completely discharged personal battery.
• Ability to take on a plane: According to international IATA rules, most airlines allow power banks to be taken in hand luggage if their capacity does not exceed 100 Wh (watt-hours). The capacity in Wh is calculated as (mAh * V) / 1000. Models with 30,000 mAh and above exceed this limit.
• Ability to charge low-current devices (LED lamps, headphones, etc.). We did not add this item to the summary table because all portable batteries from our review support it.
• For blackouts. For this usage scenario, not only the power bank capacity parameter is very important, but also the charging time of the power bank itself. If the light is only provided for 3-4 hours with intervals of 4-6 hours of shutdown, it is simply impossible to fully charge capacious power banks with a regular 18W charge. Here, power banks with powerful chargers with a charging time of less than 3 hours come to the fore. They are the ones most suitable for use during blackouts.

 

Based on all the data we have presented above, you can choose for yourself the power bank that you need: for power outages, for traveling on airplanes, or simply as a capacious portable backup power supply that is used from time to time.
