I didn't find any mention of any fast charging in OP2. 5V/2A is indicated everywhere.
Therefore, the best cable, the shorter the better, preferably a well-known manufacturer.
The power supply itself is best to support 5V/2.1 A and also be a well-known manufacturer.
Note that there are 5V/1A and 5V/2A power sources, they will charge worse, 100 mA will go to losses in the connectors and the cable itself, and various adapters will only make the charge current loss stronger! |
