Insignia 8000mAh Portable Power Bank - Black - Only at Best Buy

i use a a phone with a relatively low battery capacity (1624 mAh), and this charger can recharge it multiple times. it’s very quick as well. i don’t have an exact time/power ratio, but the charging speed is very fast, comparable to or better than a wall charger. its very solidly built and sleek. my only complaint is the status bar showing the remaining power. its a row of 4 small holes with lights beneath, indicating 25, 50, 75%, etc. you need to tilt the charger at an angle in order to view the lights, which just feels a bit awkward. however, it doesn’t detract from the usefulness. overall, i’m satisfied.

Love that it does the job. It keeps my phone charged when I leave house and I don't have a lighter thing in my old 99 model car that works. I bought a longer cord for my phone to plug into it so I could put this in my backpack purse and keep phone on it while I'm gone. The short cord is only thing that comes with it. I has 4 blue lights when fully charged.

I needed a portable external battery for my cell phone. I also wanted one with two USB ports and an indicator as to how much battery it has. This is a perfect choice.

This is a nice little charger. I think the 8000 mAh hits a sweet spot between capacity and bulk... there is enough juice for multiple full charges of my phone, but the unit has a nice and slim form-factor. Like most other battery packs I've had, it has 1A and 2A outputs, which is nice. The blue LEDs on black casing looks cool and sleek. Just a nice package all around. If you can get it on a sale, price should be comparable to some of the no-name brands out there, and less than established players like Anker, for the same capacity. But in terms of features and quality, this unit is closer to the latter (i.e. better than the "no-names").

I bought this two months ago as I was about to do a long drive and my phone battery is garbage. It worked perfectly fine, then i would use or occasionally for the next month and a half. When it was time to charge it again, I noticed it would not charge past the first stage. (One light blinking). It was able to hold only one full charge and I just didn’t think anything of it until this week when I needed it every day. It will not even charge my phone anymore. I will charge this thing ALL NIGHT and it will only have about 5 minutes of charging in it. Too late to get a refund I think but I don’t recommend.
