- How warm do these USB slippers get?
- The listed range is about 110–130°F, which is gentle warmth rather than strong heat. They are meant for keeping feet comfortable, not for therapy.
- Do they work with a power bank?
- Yes. They run on 5V USB, so a power bank, laptop port or USB wall adapter all work. You stay tethered by the cable while they heat.
- What size feet do they fit?

- About five minutes to reach their working temperature, per the specs.
