Product details

Darkhorsir is a brand which is committed to providing good and reliable products to African people.We hope our efforts can help African customers find the right products they are satisfied with from their market,which is full of bad and shoddy products.And we believe we can do it well in Africa.

Most of the power banks in the market are irreal capacity. Their actual capactity is lower than their nominal capacity.The Darkhorsir 4 built-in charging cables power bank is full 20,000 mAh capacity. And its rated capacity is above 12,400 mAh(All product parameters of Darkhorsir are supported by reliable data obtained from real testing). With 4 built-in charging cables, it will be a convenient supportive partner in your travels and working.


1. What is the relevance between nominal capactiy and rated capacity?

The nominal capacity is the maximum capacity of power bank in recharging(The capacity marked on the power bank is the nominal capacity). The rated capacity is the actual capacity the power bank could provide in discharging(Power bank charge a mobilephone). Because the different voltages conversion between recharging and discharging, and the energy consumption in these processes, so the rated capacity would be much more lower than the nominal capacity.

2. How to judge the quality of the capacity?

Generally, a qualified power bank’s transformation rate from nominal capacity to rated capacity is between 60%--65%. It means a power bank which is called 10,000 mAh, its rated capacity should be between 6000--6500 mAh. If your mobile phone battery is marked 3000 mAh, that means the fully recharged power bank could charge the mobile phone twice at least. If it could not, surely the power bank is a irreal nominal capacity.(Plenty of suppliers will mark a irreal nominal capacity which is much more higher than its actual capacity, for example, a power banck which is marked 10,000 mAh actully perhaps has half of the capacity, 5,000 mAh only.)
