Questions about this item

Which capacity version of this power bank should I choose?

This model is offered in a single 50000mAh 185Wh capacity, so there are no alternative versions to compare.

What does the 185Wh rating actually deliver when powering a laptop?

The 185Wh rating is the total energy stored; how long it runs your laptop depends on the laptop's power draw, which varies by model and workload.

What voltage does the DC output cap at and how is it set?

The adjustable DC output caps at 20V (compatible with 19V and 19.5V laptops) at up to 4.7A, set by double-clicking the power button to cycle through 5V, 8.4V, 9V, 12V, 16V and 20V steps.
