I recently bought this 20000 mAh USB external battery by Aukey from Amazon because it has good reviews and it has on a special sale a few days ago.
However, after looking at the battery in person I noticed that the higher powered port charges at 5V, 2.1A Max. This picture of the back of the Switch console shows that the console's power input is 15V, 2.6A.
Would the external battery I purchased be sufficient to charge the Switch on the go? Or should I return the battery and find a different option?
