LG’s X series of smartphones is still fairly new, having only debuted back in February, but it’s getting rather large thanks to an new expansion that adds four members to its family.

LG today announced the X power, X mach, X style, and X max as the four newest additions to the X series of Android smartphones. As with the other X series devices, each of these four new phones has a special feature to help it stand out among the others.

The X power’s claim to fame is its battery, which measures in at 4100mAh and also offers fast charge technology that enables it to recharge at twice the rate of normal charging. Meanwhile, the X mach is all about speed, offering LTE Cat. 9 3xCA data speeds. The X mach also boasts a Quad HD (2560x1440) display and 1.8GHz processor.

Next up is the LG X style, and as you might’ve guessed, this one’s all about design. LG boasts that the X style has an “elegant design” with “gracefully curving lines” and a slim body. Meanwhile, the X max has a large screen for consuming video content, but LG hasn’t divulged exactly how large that screen is.

LG also isn’t saying much about the availability or pricing of its four new X series phones. The company says that launch and price info will be announced locally for each market.
