    Portable charger is lightweight--great for festivals/on-the-go since it doesn't add bulk. Charges phones rapidly; gives about two solid full charges--wish it had more juice but overall would reco.

    Very nice product. Perfect if you don't want to bulk up your phone with a Mophie type Battery Case. I pretty much only use it when I travel or use my phone excessively on a given day. It can also be used simultaneously to charge your other USB devices like a Kindle or tablet.

    The RAZORMAX Portable Power Bank keeps your phone and other compatible devices charged beautifully. It has a power bank that features a 6000 mAh battery for up to 27 hours of talk time. Two built-in USB ports allow you to charge multiple devices at once.

    i love this power bank! Not only is it aesthetically appeasing, it also holds a great charge, I'm constantly on the go and nothing is worst then being at 1% and there is no outlet in sight! And the best part it's fully charged before you open it! (bonus!) It has two USB ports where you can charge 2 devices at the same time, its capable of charging iPads to a full charge while charging my iPhone. It also has a power indicator when you shake the bank to show how much juice you have left. Here are some tips from me to get the most outta your bank. 1. Once finished charging a device make sure you unplug your USB from the bank it will drain your bank even tho nothing is being charged. 2. Put your device on airplane mode to charge your device faster (plus take a break from the phone seriously rest your eyeballs) 3. Beware of excess wires hanging out of your pockets while charging don't wanna get snagged on a door handle. 4. Don't forget to charge your bank after a days use (it's a pretty brick if not charged)

    Jealousy influence purchase

    My boyfriend got a power bank from this company last year for Christmas from his parents. I've been continuously stealing it for a year since then. It's gotten to the point where I was going to Vegas for a work trip and thought it would be a little weird asking to use it for a week. So I finally caved in and bought my own. This one's better than his because the last twice as long, it is slightly thicker, I haven't really used the two phone charging function that I can charge two things at once but in general great. Now he's jealous of mine.

    I love this; it is small for my purse, but powerful! I can fully charge my smart phone 3 times on one charge of the portable. Or, i can charge my tablet and my cell phone; even simultaneously. It has a charge indicator to let me know how much charge is left in it.

    Charges my devices quickly and holds enough juice to recharge multiple devices or recharge my smartphone multiple times. It often can go days before having to recharge the power bank. Some USB power adapters don't recharge the Power Bank as quickly as others.

    I really love this battery pack. It's easy to tell how much charge is remaining (just give it a shake and look for the LEDs to light up). It also conveniently charges with the same micro USB cable used to power and recharge android devices! Super easy.

    The sales associate recommended this charger to me. He explained to me that I could expect to be able to recharge my phone 5 times on one charge and the low profile of the charger could easily be carried in my pocket. Love this charger.

    My wife and I had been planning a long trip and wanted an option for her old and dying iphone 5s. This worked great and was totally worth every penny, it holds a great charge and recharged her phone very quickly.

    This portable charger has worked amazingly well. I get 2-3 full charges on my s6. Fits in my pocket with my phone so it's not that bulky. Only thing that I can do with is maybe aa longer charging cable it came with

    Was amazed at how quickly I was able to charge my iPhone while I was on the beach. Its compact size is perfect to carry. Was able to charge both mine and my daughters iPhone and still had power left to charge another.

    Great thing to just have in your backpack if you're a college student. You can't always get to a wall outlet when you're in class but this ensures I never have a dead phone or tablet.

    It's easily portable and works much faster than my car charger (the reason I purchased this item). When you shake it, it will light up 4 lights to show you how much charge is available.
