What to know before buying

Listing details to confirm

The title identifies Sevdiea and a 16,000mAh battery pack, while the battery details separately state “1 9V batteries required. (included)” and the product description specifies a 7.4V DC port. These power details are inconsistent, and the listing does not confirm runtime by heat setting. It also does not clarify whether the included battery referenced in the title is the same item as the listed 9V battery. Confirm the supplied pack and connector before buying. The manufacturer advises using the equipped power bank and removing it before washing.
