    This is a great portable charger. I was doing a little shopping when my battery just died on my phone. I went into Best Buy to purchase a portable charger. I was thinking of spending about 60 to 70 dollars. They have a variety of them. This particular one was on sale for about 25 dollars. It works great! I can carry it around in my purse on in my hand. It's not bulky or oversized. I can charge my phone at 4 times with a full charge before it needs charging. The only piece you need to charge this is an wall adapter because it comes with the charger. It is partially charged when yoy purchase it.

    For years now, decades really, I've yearned for the ability to charge something without being tethered to an electrical outlet. Wall sockets are soooooo 20th century, don't you think? Well huzzah and fruit roll-ups, that day is here! I plugged my iPhone into that sexy little Insignia charger and ran around the living room like a proper loon. Dare I say it, I was giddy, YES, GIDDY with the freedom it afforded me. I then tested my daring by stepping even further away from a proper electrical source and walked through my front door into the wide open spaces of the outdoors. I nearly wept. I was outside. I was outside and charging my overpriced and rapidly obsolete communication device feet and feet away from any three-holed electrical receptacle. I was overcome by the sheer awe I was experiencing. I passed out. When I came to my iPhone was fully charged. The little Insignia device still ready for more. "I regret I have but one iPhone to give you, little Iggy." I named my charger Iggy prior to my blackout, you see. He seemed to understand and was fine with it. As was I. It was a full day and all I could think of was foraging for some sustenance, crawling into bed, and dreaming of my new life, cordless and free. And this time, I did weep.

    Bought this while at the airport and needed some juice and have loved it ever since! Not only was the price standpoint great, the form factor is small and fits great in my pocket. It also has enough power to recharge my device a few times. Would highly recommend!!

    This charger is more compact and fits in my pocket more comfortably. Additionally, it is not as heavy and lasts as long as I need it to because I charge it back up every evening. I absolutely love it and wish I had purchased one earlier! :)

    After many BB employees determined that they had no idea these were even sold in the store, I decided to just go for it and see what happened. I'm glad I did, this charger packs a punch. It charges my Samsung S5 from <20% to 100% ridiculously fast (~1hr), and still has over half of its life left. I've yet to try it with my tablet, bUT I could easily see it charging my phone and Tab S without any issues. The downsides are: It takes forever to recharge. At least 8-10 hours to fully recharge when it reaches the last bar. That's annoyingly long. It's a bit heavier than I'd like. If I toss it in my purse, I can feel it.

    Small compact portable power source with enough storage to fully charge your phone 2-3 times. You can also charge 2 different devices at the same time if you want. Perfect for camping, hiking, and remote job sites where AC is not available,

    Bought this charger because it was on sale and because of the capacity compared to other brands. Works really well and can charge my phone and my wife's phone at the same time. Only thing I don't like about it is that this charger doesn't have a flashlight which came useful to me when I'm out camping.

    Always have your phone charged even when no AC is available. This will charge an I-phone fully 2-3 times. Perfect for hiking, camping and remote job sites. Small compact and powerful and can even charge two devices at once if needed.

    Super Fast Charging & Plenty of Power

    I was pleasantly surprised with this little Insignia Model: NS-MB7800 (SKU: 9195111) Portable Charger. Since, I have a (Samsung Galaxy Note 8.0) tablet with a battery that is going bad, as a last-ditch effort, I tried using this portable charger & was shocked (no pun intended) at how fast it re-energized my tablet battery (way faster than if I had plugged the tablet in to my house wall outlet!). Also, you can charge up to 2 devices at once & it is small, slim & lightweight enough to carry around with you. But, if you need to charge more than 2 devices at once (& have a little more mAh) ~ I would recommend spending $3 more & getting the slightly larger Insignia Model: NS-MB10400 (SKU: 9199117), which gives you an additional USB port (the ability to charge a total of 3 devices), but is slightly larger, bulkier, heavier than the 7,800 mAh model.. I am very pleased with this smaller unit & (when not charging it back up), it usually stays permanently attached to my Galaxy Note 8.0 ~ I even refer to it as "A TAIL" Before, I was ready to get rid of my tablet because of the battery issues, but this little portable charger has given my old tablet "new life". Very pleased with it's performance.....fyi: it takes a really long time for it to drain entirely & for it to require re-charging; I can, literally, use it "all day" but, like I said ~ if you think you need more than 7,800 mAh, I would suggest moving up to the 10,400 mAh unit, just be prepared to tote around a bit more bulk & weight (my boyfriend has one of these larger models)

    I bought this item to replace the charger I gave to my bother-in law. I am so happy with this charger. It's compact, sturdy and the material is not cheap. Charges fast and easy!

    It has been reliable in times of need. It charges 2 phones no problem and it fits women's pants pockets. It also charges my LG90 3 times over which is very nice since I sometimes forget to charge both my phone and the charger. It also has a button that when you press it, it shows you how much battery is left which is also extremely convenient.

    This charger works very well, and it charges my iPad very quickly. I like that it has two charging ports capable of charging two devices at the same time. The charge level is clearly indicated by the lights on the front. This product is cheaper and has more features than several other products similar to it. It's got the perfect combination of compact size and enough power to charge an iPad. It charges iPhones quickly as well.

    Got this for a trip to Disney. With all the pictures and videos, we needed the extra juice. Charged 2 iPhones and device still had 1/2 capacity left. Don't be fooled by it not being name brand. This was less than 1/2 the price of the other name brands.

    Great little device to have with me when I'm on the road or want to charge my phone while it's in my possession (as opposed to sitting on my desk). It holds its charge well and it also seems to "quick charge" faster than if I plug my phone into a wall outlet using the standard wall charger. Nice!
