Don't leave home without it.

It's a very slow charge, but oddly, I didn't buy it for the purpose of charging. My Nexus 5 has a well known bug -- since Lollipop -- involving sudden shutdowns when using the camera and listening to music. Whether or not you are able to reboot, the phone believes that your battery is down to nearly zero power left -- that's where this flat battery pack comes in handy. I plug the phone in and I'm able to reboot; the phone will then recognize that the internal battery is not near 0, and operate as usual.

The two features that make it better than most others:
1. Built-in micro-USB cable and plug, that tucks away when you're not using it;
2. Flat enough (~9mm) and light enough to fit in your pants pocket or shirt pocket without getting in the way.

Love it, LOVE it, LOVE IT!!!!! More than you'll ever be able to read in the palm of your hand and so much more! The books, the newspapers, the magazines, surfing the web. The MP3's to listen to while you read is a big plus. Now you have something else you should not leave home without!!

Love it.  Just used it on a rental car driving from Louisiana to Mississippi and back 3 days straight.  I won't leave home without it in the future.

You can never have enough of these things lying around.  I keep one in my car, one in my junk drawer at home and another in different luggage bags ready to go.  They also make great gifts - people always need POWER.

This one is great because it's compact, and has a light.  I like the flashlight - some battery packs have this and some don't, but it's oddly handy when it's there.  I use it in hotel rooms and stuff.  Real nice.  Anyhow, yes it charges my phone just great.  I don't worry about the time it takes to charge, etc.  I use these solely as backup in case my phone dies or gets low.  Keep this on you with a multi-phone usb cable (search for them here) and you'll be everyone's hero when you're at a bar and someone phone is gonna die.

I take it everywhere, just put it in my wallet and I am ready for music picture and video sharing. Don't leave home without it.

This little accessory has come in useful so many times. Both for my phone and laptop as well as helping my parents, that I'm thinking of getting a second one. So small and compact, you hardly notice it in your pocket. Never leave the house without it. Highly recommend.

A must have!  We have 2 of these and turn them on when we go away from home for more than a day.

I love this knife!! This is a replacement for oneI left in El Salvador for a friend.  I've had this knife for years -- never dulls. It is the PERFECT knife b/c it's not bulky, and yet it has every tool you'd ever need: knife, awl, Phillips head and flat head screwdriver, pliers with two sizes,  bottle opener, and scissors.  I use at least one of the tools on a daily basis.  It is an essential piece for my purse.  I don't leave home without it.

Just the sound gets attention.  How do you rate a product that would require you to put yourself in harms way or assault someone to test it.  That being said,  I do not leave home without it.  It is so handy I carry in my front pocket.  Drop it in your luggage [not carry on], and you have it with you while traveling.  In this age of civil unrest why leave home without it,  and mister CCW.

Unbelievable. Do not leave home without it. I have a few of these things so I'll never be without at least one. Takes just a few seconds to load a clip and no fuss doing it.  Just great.

Never leave home without it....just kidding. I cook with it all the time although I temper it with other spices and herbs since it can get a little hot if used over zealously (with hot chili powder....a mistake I continue to repeat..lmao)

I love the battery level indicator feature, comes in handy.

The charge lasts forever and I can get 4-5 charges for my phone out of each use.
don't leave on a long trip without it.

This has to be one of the most convenient travel items a person can carry with them while traveling IN and OUT of the United States.  It covers the US, United Kingdom, Europe and Australia.  NOT only that, it charges iPads.  When I used to order chargers/plugs for my iDevices, I never understood why my iPad wouldn't charge.  I always thought I had a broken device.  I've since learned that the makers of the chargers didn't use a high enough ampage to charge the iPad.  This item does.  It even lets you know which port to plug the iPad into.

When switching from one country/outlet to another, you have to give it a good 'push,' which is good because you don't want the plug to be weak and move easily without any pressure being necessary.

I'm not familiar with the size of other adaptors but it won't take up too much space and it comes in a nice case.  I highly recommend it for any traveler or even for people who need an adaptor in the US.

I was provided and complimentary/lower priced item for my honest opinion.
