The Samsung Galaxy S4 comes with support for the MHL 2.0 standard, which aside from streaming high definition content to your TV or monitor set can also allow the external screen to charge the smartphone along the way. The Galaxy S4 is the first smartphone to offer the MHL 2.0 standard, which means that you no longer need to plug in a charger in your adapter.
Now, the good news is the first Samsung-made adapter is already available and can be yours for £33 or around $40. It still comes with a microUSB port for charging, so it’s backwards compatible with MHL 1.0 devices like the Galaxy Note II and Samsung Galaxy S III.
You can find the 33 quid adapter here.
