You want a big battery?Eric Falk OK, but be prepared for some downsides.

Energizer, the battery company, is now building phones (a whole bunch of them, too), and one of the most interesting devices they brought to the Mobile World Congress trade show in Barcelona is an 18,000mAh battery phone.

Yes, that's 18,000mAh -- roughly seven times the capacity of the 2,659mAh battery in the iPhone XS.

The Energizer Power Max P18K Pop is actually quite an interesting device. Besides that humongous battery, it has a 6.2-inch notch-less screen, a triple, 12/5/2-megapixel rear camera, a dual, 16/2-megapixel pop-up camera, 6GB of RAM and 128GB of storage. It runs on Mediatek's Helio P70 chip and comes with Android 9.0.

But it won't be remembered for any of that. It will be remembered as the fattest phone of MWC 2019. I mean, just look at it.

I've stacked three phones on top of each other to match the P18K Pop's size. I've compared it to a Samsung Galaxy S10+ and people around me laughed. It's just looks absolutely bonkers -- it's fatter than my 26,800mAh external battery.

If you don't mind its size or its weight (I don't have an exact number, but it's heavy), the P18K Pro could be quite useful -- its battery probably goes on for days if not weeks. I've had very little time to test it, and some over-eager visitor broke its selfie camera by pushing the pop-up module down manually. But judging by its specs, there's no reason why it shouldn't be quite a capable Android device.

The Energizer Power Max P18K Pro will launch this summer. The price has not yet been revealed.
