## Before you buy

- Listing details are inconsistent or unconfirmed: dimensions are given as both 11.9 x 6.9 x 2.8 centimetres and 12.9L x 8.8W x 3.5Th centimetres, the stated 5-hour recharge time differs from customer reports of very slow recharging, and customer feedback mentions up to 8 hours on medium while the listing claims 5 hours on medium with all heating zones active. Confirm garment compatibility and relevant runtime expectations before buying.

## A good fit for

- People who need a battery pack for heated clothing with a compatible 7.4 V DC connection.
- Buyers seeking one portable battery for compatible heated gear and USB-powered phones, tablets or fans.

## Less suited to

- Buyers prioritising an especially light battery for all-day pocket carry.
- Buyers who require a clearly established size or recharge time before purchase.

## Customer feedback

Customer feedback describes the pack as reliable and pocket-friendly, with positive reports about warmth and battery life. Opinions on charging speed are mixed, and some feedback calls it heavy. Those points matter if you plan to carry it in clothing or need a predictable recharge schedule. Customer-reported runtimes should be distinguished from the manufacturer's figures, which specify 4 to 7 hours depending on heat setting.
- Positive themes: Customers describe it as reliable and small enough to fit in a pocket.
- Positive themes: Feedback highlights warmth and battery life.
- Negative themes: Some customers describe the power bank as heavy.
- Mixed feedback: Charging speed receives mixed feedback, with reports of quick charging as well as very slow recharging.

## Frequently asked questions

### Can this power bank run heated clothing?
The listing specifies a 7.4 V DC output and names heated vests and jackets as compatible devices. Check that your garment uses a matching connection and power requirement.
### What outputs does the K9 Max have?
The product listing describes three outputs: DC, USB-A and USB-C. USB-C is also listed as an input.
### How long does it run heated clothing?
The manufacturer claims 4 hours on High, 5 hours on Medium and 7 hours on Low with all heating zones active. Customer feedback also mentions up to 8 hours on Medium, so actual results are not established and the claims differ.

The specifications list 5 Hours, while customer feedback is mixed, with some describing quick charging and others reporting a very long recharge. Treat the listed time as a claim rather than a guaranteed result.
