IOGear GMP10K GearPower Mobile Power Station Review


Looking for a mobile battery to charge all of your electron-sucking devices? Look no further. The IOGEAR GMP10K is the mac-daddy of them all. This 11,000 mAh portable charging station is the closest thing to taking a gas-powered generator on all your business trips, camping adventures, or just to keep handy in case of an emergency.  The GMP10K will keep your entire quiver of devices trucking through even the heaviest of travel days and road trips.


Most portable batteries range from 1000-6000 mAh depending on how big you want them to be, how much you want to pay, and how cheap of a brand you’re comfortable buying. Hands down, this is the one to buy. Not only does it charge any smartphone, it charges tablets as well unlike the million other portable chargers out there. The IOGear GearPower GMP10K features two USB ports; one being 1A, and the other being 2.1A. The 2.1A port is geared for charging tablets and it charges smartphones a bit faster than the 1A. In perspective, this battery is almost 8 times the size of the iPhone 5 battery and 2.5 times the size of the iPad Mini battery. It is about equivalent to that of most 10" tablets such as the iPad 4th generation, the Nexus 10, and the Surface RT.

The two major bonuses with this battery are the multiple USB ports and the fact that it can charge most phones more than five full times without needing to be recharged. Other strong points are the included case, the fact that it doesn’t require proprietary charger (micro USB), the four LED icons to indicate how full the power station is, as well as a built-in IC chip that tells the battery to stop charging devices once they’re completely full without damaging the batteries of the devices being charged.



Size is the biggest downfall to this battery (no pun intended). Most portable chargers are small enough to stick in your pocket with your phone without looking gaudy or out of place. I would compare the size of this battery to two iPod classics stacked on top of each other. Also, devices don’t charge as soon as they’re plugged in. One must initiate charging with the press of a button which really isn’t a big deal but if you have it tucked deep into your travel bag, it might get in the way a bit. The IC chip is designed to maintain the health of the batteries of the devices being plugged in so they aren’t overcharged. The problem with this is that when charging devices overnight, they hit 100% hours before someone wakes up, meaning there’s a few hours’ worth of standby time drained from the phone or tablet.



This is a sweet addition to your array of mobile devices. I’ve been using my unit for a month or so and it has come in handy multiple times as it usually sits in my backpack ready for use at any time regardless of where I am. It is almost sure to always have juice in it as I neglect to remember to give it a recharge. I plan on using it for long road trips and ski trips to charge my phone, tablet, and GoPro. Though the device costs $80, it would be the last power station you should ever need to purchase. I currently have a 2000 mAh battery that doesn’t quite do the trick anymore as it doesn’t hold quite the capacity that it used to, especially with my ever-growing arsenal of devices that could use the juice on-the-go. And at a whopping 11,000 mAh, even if the IOGEAR GMP10K loses some of its juice over time, it should still be ample to charge all of your devices multiple times.
