Question: how much time it takes to charge a 10000mah power bank?
Answer: In this case time taken would be 10000mAh/2000ma = 5 hours as per mathematical calculations. In practical scenarios, 10k mAh power banks take around 6hrs to get fully charged using a 2A charger. If it's a 1A charger it would consume double the time. Which means it would take 10 to 11 hrs.
