Mophie is one of the most popular manufacturers of mobile electronic batteries for several hot devices, and this latest offering from the Michigan-based company lives up to the name and hype.
This is an extremely rugged external battery pack that will recharge your Nexus 4 from empty to full over 2 times. The battery housed in this unit is massive: 6,000mAh. The battery that’s built-in to the Nexus 4 is 2,100mAh, so as you can see, you’ll get some substantial juice out of this box. When recharging a phone or device with the pack, it’s never a 1:1 ratio of power conversion, but it’s close.
The PowerStation Pro is also very rugged, as you can probably tell from the pictures. The specific rating it carries is IP-65, which mainly entails dust and water protection. It’s not submersible, but it’s splash proof and shock proof. That means you can spray it down with a hose and it’ll be okay if all the grommets are sealed. It’s also dust-proof, so that means it’s sealed air tight and won’t let dust and dirt in.
A solution like this is the only way to carry “an extra battery” for the Nexus 4, and it’s safer anyways because loose batteries are fire hazards of their connectors are exposed. You can easily throw the PowerStation Pro into your travel bag and not worry. In fact, you can put it at the bottom of your travel bag and not worry since it’s built like a tank.
A micro USB charging cable is also included, and there’s multiple LED’s on the housing that let you know charging status and juice left in the battery.
This is currently on sale, and is pretty much universal. You can get one of these, and you should be able to charge your next 2 or 3 cell phones (probably even more, but there’s no telling where mobile technology will be in 5-6 years). That makes this a good pickup and easy investment. It also charges tablets. Mophie also offers a 1 year warranty on this, which is exceptional for a battery.
