The 5 Best Power Banks

A portable power bank can save your phone when you’re down to your last bit of battery. And let’s face it, nobody wants to be stranded without their cell phone. Fortunately, power banks are small, affordable, and easy to use, so you won’t ever have to panic when your phone or tablet is running low on battery juice ever again. With the small external chargers, you won’t ever have to worry about your battery running out in the middle of a call. You can talk to your friends, play games, listen to music, or surf the internet for as long as you want, without having to worry about finding a nearby charging station.

In fact, some power banks can charge your smartphone more than four times under one full charge. To get the most from your investment, it’s important to choose a power bank that best fits your lifestyle and budget.

What is a Power Bank?

A power bank is a portable battery charger that can recharge your battery whenever you’re running low on power. This will make it more convenient to use your phone or tablet whenever you need to, without having to search for an available wall charger. All you need to do is plug your phone into the portable charger and continue on your day. The phone will charge with enough power to get you through your day and you can easily recharge the power bank from any USB port once you get home. These are ideal for when you are traveling, on business, or just to keep in your car or bag for a quick emergency charge. At some point in time, you’ll find yourself on low battery power, and will be glad you have the portable power you need.

Well, seems to me you are far away from OUTSTANDING power banks. Part of my job is selling power banks years ago. The best power bank is no doubt Pineng followed by Yoobao then Mili. For car jumpers there isn't any better than Zeta-Jacko followed by Yoobao.

I bought many portable chargers and they all start to fade away and don't hold up as much power compared to when I first bought it. Maybe these other brands might be better I will have to give them a try. However, ill suggest the Powergo ss 5000 from Its not put on the list here surprisingly. I have owned this product for about a little over 4 months now and I must say its my new must have portable charger. Its recharges so much more faster then the previous power banks I owned. It recharges itself so quick that I can feel its like 15 times faster charge speeds then any other portable chargers I have owned including my new Qualcomm Q.C. 3.0 portable charger I also bought from amazon to give it a try. the power bank pretty much finished charging itself in like under 15 minutes. When I use it to recharge my iPhone it recharges not as fast but I can tell it charges much faster then my wall charger. I would have to recommend the powergo ss 5000 to anyone who wants a really quick charging power bank.
