What to know before buying

Listing details to confirm

The title and feature text claim 6000mAh across two 3000mAh warmers, 8–20 hours of heat, 3–4-hour USB-C charging and compact 9.6cm, 68g units. The details instead list overall dimensions of 13 x 10 x 2.7 cm and a weight of 150 g, and the battery field says one included 9V battery. These listing details are inconsistent. Confirm the selected variant’s unit dimensions, weight, battery and charging arrangement before buying. The claimed run time may vary with heat setting.

Frequently asked questions

How many warmers are included?

The listing identifies a two-piece set and describes two 3000mAh warmers, with 6000mAh total capacity.

How long does a charge last?

The feature text claims 8–20 hours of continuous warmth. It does not specify the heat setting for each runtime, so treat that as a claimed range rather than a guaranteed result.

How are the warmers charged?

The feature text describes USB-C charging and a dual-port cable for charging both units at once. However, another listing detail says one included 9V battery, so confirm the actual charging and battery configuration for the selected listing.

Can the units be used separately?

Yes. The feature text says they can be used separately or locked together with a sliding design.
