ASUS Power Case (CB71) For ZenPad 7.0 Review

Spread the love


The ASUS ZenPad 7.0 is a cheap and cheerful mini-tablet. Powered by the low-cost Intel Atom x3 chip, it is never going to win any speed race. If you are looking for a mobile 3D gaming machine, then this is not what you are looking for. But it is perfect for 2D games and video playback, as well as office work.

When we reviewed the ASUS ZenPad 7.0, one of our biggest gripe was its rather limited battery life. It can last up to 6 hours with light use, or 4.5 hours of heavy use (PCMark rated) and about 3.5 hours if you are playing games on it. But ASUS has just the solution for you – the ASUS Power Case (CB71) for the ZenPad 7.0!

The ASUS Power Case is a power extender specially designed for their ZenPad series of tablets. They look like a normal ZenCase, just with a built-in battery that doubles the ZenPad’s battery life. Let’s see if that claim holds true! 😀

Unboxing The ASUS Power Case

The ASUS Power Case comes in a classy-looking cardboard box. The large ASUS ZenPad 7.0 branding in the front makes it clear that this Power Case is specifically designed for the ZenPad 7.0, not its larger brother – the ZenPad 8.0.
