Can i charge my power bank battery in a power outlet?

I recently bought a 'KOCASO' 2600mAH Power Bank. It's currently empty. It says on the manual that i need to connect it to the computer to let it charge. But can i just directly charge it to the power outlet? Since i have an USB AC Power Charger Adapter (from my iphone)… Can i just connect it to that and charge it to an outlet?

More Details about my Power bank: (in case you ask) [according to the manual]

If your charger has a 5 V d.c. Regulated output and a connector compatible with the power bank's, yes, you could charge it without using your PC.
