Samsung to release a multi-charging USB cable – charge up to 3 devices at once
Samsung, having already made a foray into smartwatches and wireless headphones, understands that its users may be suffering from a similar problem, only multiplied by two. To help alleviate such problems, Sammy will be releasing a multi-charging cable. It's a piece of kit that plugs via USB into a wall charger on one end and has 3 micro-USB plugs on the other – allowing one to charge up to three mobile devices simultaneously.
The cable is said to distribute the 2 A of power that come from the wall charger evenly across 3 devices. This means that if you have a tablet, a smartphone, and a smartwatch plugged in, each will receive around 0.667 A. This will make them charge slower than usual; however, it shouldn't be a problem if you just plug your devices in for the night. If you wish to speed charging up a bit – you'd have to unplug one of the devices, giving the other two 1 A each. Naturally, leaving just one plugged in will give it a full 2 A charge for a normal charging time.
Sammy claims that the cable will be portable and "a perfect accessory for the on-the-go mobile device user". The shop page lists it as “coming soon” with no concrete release date, its price is pegged at $39.99.
