This is the best portable charger out there right now, and you can even get a great price on it online. Good. Incredibly large battery (23,000mAh) will charge your phone, table, or even your laptop. Can charge 3 devices at one time.
The battery is a DC (direct current) device as it produces  unidirectional current flow.    A charger is a device that produces a DC voltage. We usually think  of this device as being plugged into an AC source (like a wall  outlet). The voltage it produces is slightly higher than that of  the battery it is designed to charge. All we need to do is hook the  charger up to the battery and the battery charges.
