Does it heat a cold drink or only keep it warm?

It heats. The 300W element warms the liquid to the temperature you pick, from 45°C up to 100°C, and the vacuum body then slows cooling.

Can I use it without the cord?

No. Heating requires the included US-style power cord; unplugged, it works only as an insulated mug.

How much does it hold?

400 ml, about 13.5 fl oz, roughly one large coffee.

The top setting is 100°C, so it can bring water to a boil, but 300W is slow and the small capacity suits single cups.

The input range is 100–240V, but the plug is US-type, so you need a plug adapter for other outlets.

Is the inside safe for coffee and tea?

The interior is 304 stainless steel, a common food-grade grade for drinkware.

Our take on the Kowaku Electric Heating Travel Mug

The Kowaku is a 13.5 fl oz travel mug with a built-in 300W heater and six preset temperatures from 45°C to 100°C, so it warms a drink rather than only slowing its cooling. A 304 stainless steel interior and vacuum-insulated body hold heat between heating sessions, and a digital display near the base shows the liquid temperature. It runs on a US-style cord from 100–240V, which makes it a desk or car-adapter mug rather than a fully cordless one. Against plain vacuum flasks it adds active heating; against battery-powered heated mugs it gives up cordless freedom for stronger, faster heat.
