This may have just saved my life.


It is early 2014 and we are getting an artic blast here in good ole USA. -10 F and blizzard conditions.I had to drive 270 miles through a mostly rural state.
My rental car has a USB port for charging my phone which is also my GPS. I am set and ready for the journey.

shortly in to my trip the weather and the roads turn nasty and my 4 hour drive is now a perilous journey. Did I mention I am doing this between 11pm and 5 am? ohh yeah I am.

Average speed is now reduced to about 45 or 50 MPH. My once 4 hour trip is gonna be a lot longer. I hunker down and get on with it. On my phone I am playing an audiobook while the GPS guides me to my destination.

I am still 2 hours away when my phone pops up that it’s battery is almost DEAD. Whaaaattt! I can see that it is charging, how is it dead? Well the anemic amperage out of the USB port in the rental car wasn’t enough to cove the power usage or the phone. I quickly shut screen off to hopefully save precious seconds of battery life. I dont have a car chager with me, I am not sure how I am going to make it with out the GPS and now at 3ish am on a country road in the snow no one is going to find my frozen dead body till spring, when it hits me. I have my Gorilla battery pack that I use on long flights to power my tablet and phone.

I wip out the Gorilla pack, plug in my phone to the 2 amp usb port and pray this will get me to my hotel. My battery symbol is still red and my Gorilla pack is only half way charged…. I am not sure this is going to work.
I cautiously navigate the road ahead and try to memorize the next few turns from the GPS.
Then I notice my phone battery is not in the red anymore, in fact my phone is charging and providing GPS and not loosing charge. in fact it is gaining charge. Wooo Hooo I am going to make it.

Pros:Works, hold a charge forever, has 2 Amp USB port, can be charged via mini USB.

Cons: Takes forever to recharge this pack (like over 8 hours), is a bit heavy, it is not clear when it is outputting voltage or not you have to rely on the gadget your charging to tell you.
