What to know before buying

Listing details to confirm

Capacity and runtime claims are inconsistent across the listing: the title and details give 14000mAh, while the feature text specifies a 10000mAh case plus two 2000mAh warmers. Runtime is stated as up to 10 hours generally, but the detailed description gives up to 10 hours on low, 7 on medium and 4.5 on high. Confirm which capacity and runtime apply to the selected version. The listing also describes a 60°C protection cut-off, distinct from its 35°C to 55°C operating range. These are listing discrepancies, not established product faults. Use is described for hands and pockets, not room heating.
