The smart suitcase that weighs itself and charges your phone is launching in the UK this week

Flying is always stressful, and trying to cope with size and weight restrictions on luggage doesn't help.

Fortunately, there's a suitcase on the market that can weigh itself.

American luggage company Raden recently launched a line of smart, self-weighing suitcases, which are due to be sold in the UK this month.

The cases work alongside a free app that pairs with your suitcase via bluetooth and provides current weather conditions, traffic alerts, case location and details on your flight, making it easier to plan your next trip and get through the airport with ease. The suitcase also charges your phone on the go.

Raden's suitcases come in two sizes - the larger A28 Check case which retails at £340 ($419) - and the $295 (£200) A22 Carry which is small enough to fit in the overhead storage bin (and on offer for £250 ($308)). A set of two costs £510 ($629).

The New York-based company, which launched in 2013, has recently made its suitcases available for international purchases on Netaporter.com, and will be stocked in Selfridges in London from November 25.
