Detail:
The 20000mAh power bank comes in an environmentally friendly ABS plastic housing with a textured pattern aimed at improving grip. The plastic makes for a far better finish, as it doesn't make the surface of the power bank nearly as slippery as the aluminum design. The casing is also scratch-resistant, and can withstand heat up to 90 degrees Celsius. With an overall weight of 338g.
