Based on the information I have, it seems you are asking about whether the Anker Laptop Charger (140W, 4-Port, PD 3.1) needs to be plugged in all the time to charge devices like tablets. The charger itself does not store power, so it must be plugged into a power source in order to charge connected devices such as tablets. If you're looking for a device that can charge without being plugged into a power source (like a power bank), this product does not serve that purpose—it acts as a direct power supply.
