I found the ultimate desk gadget for $29 at Kmart: ‘I didn’t know how badly I needed it’

A humble $29 warming mug from Kmart has captured the attention of shoppers across Australia, with thousands praising it as the ‘ultimate desk-side companion’ for work, study, or busy mornings with young children.

The budget-friendly gadget has quickly become a cult favourite for its ability to keep hot drinks warm throughout the day – an issue many say they’ve struggled with for years.

The Kmart warming mug includes a sleek mug with a 270ml capacity and a discreet USB-powered warming plate that keeps beverages at a consistent 55C.

Kmart’s version is a dupe of Ember’s temperature control smart mug ($219) – which has a built-in battery as well. 

But everyday Aussies don’t have over $200 to spend on a mug warmer, which is where Kmart comes in. 

Since appearing in stores, the $29 gadget has generated a storm of reactions online, with fans flooding social media with rave reviews and desperate pleas for restocks.

‘Oh my god, I need one of these – as an office worker you never get to finish a drink while it’s hot!’ one user posted.

Another added, ‘Where was this when I had toddlers? I used to microwave my coffee three times before I even took a sip.’

The device’s practicality appears to be its biggest selling point.

From remote workers to parents juggling chaotic mornings, many say the mug has changed their daily routines.

‘This would be great for when I hyper-focus. I keep forgetting about my drink, and it always ends up stone cold,’ one user commented.

The mug is designed with convenience in mind, offering a simple on/off switch and plug-and-play functionality – making it suitable for home offices, shared work spaces, or even beside your bed during winter.

According to Kmart, the mug is ideal for ‘savouring coffee, tea or hot chocolate at your own pace’, and its compact size makes it an unobtrusive yet efficient addition to any setup.

Unlike traditional thermal flasks, which can be bulky or affect the flavour of drinks, this device allows users to enjoy their beverage from a classic cup while maintaining optimal temperature.

Despite its growing popularity, some shoppers have voiced frustration at not being able to find the item online.

‘Argh. I need this so bad but can’t find it anywhere,’ one lamented.

Others have even called for Kmart to begin offering international shipping options.

‘I need to have this shipped to the US,’ said another, highlighting the demand beyond Australian borders.

However, not all feedback has been positive.

A few have pointed out the potential for misuse, with warnings circulating about mistaking the base for a wireless phone charger.

‘Literally label the bit the cup goes on. I saw a post where someone melted their phone thinking it was a charger,’ someone warned.

Some practical-minded commenters also suggested more traditional alternatives.

‘Just buy any decent travel mug – Yeti, Nespresso – or just drink it before it goes cold,’ one remarked.

Yet, supporters of the Kmart warming mug argue it’s less about the product itself and more about the small comfort it offers in a busy world.

‘These are amazing. I have them in multiple rooms in the house,’ one shopper shared.
