    Don't waste your money on cheaper chargers.

    Good value. Charges phones quickly. Compact and can fit in your pocket when on the go. Light is a bonus. It re-charges quickly as well. Perfect for long trips when you do not have the ability to charge in an outlet. I bought a less expensive charger and was very disappointed with its performance. I wasted my money on the cheap one.

    This portable charger has charged my ultrabook and Iphone at the same time without an extended wait. It has been great to take camping. I can charge it in my vehicle on the way to the campground and and it charges my phone several times when there is no access to electricity. I carry it in my purse when traveling by air so that I don't have to plug in at airports.

    This is a great item for mobility. Have been passing around the car or plane trips to top off phones and iPads on long vacation drives or when charging source not available. Charges fast and has the flexibility of USB and miniUSB ports. Unit is compact. Can't go wrong.

    This gadget is great! After a big power outage and no way to recharge my phone or iPad, I went looking for something that would solve this problem for future storms. For a reasonable pice, I found this item and got one for all the kids. It was originally just for safety purposes, but I use it all the time if a plug is not convenient! It's going to be great for camping and hiking too. I can get a good charge on both devices...highly recommend it.

    Bought this charger for my wife as a Mother's Day present. Scored some major points. I like it so much that I had to by one for myself also. This charger is great for those who spend a lot of time on the field away from a power source. This charger will charge your phone quickly and fully 2-4 times. I don't worry about low battery on my phone anymore. The charger easily fits in my pocket and goes wherever I go. I'm also able to offer a charge to friends on the field and still have plenty of power to recharge my phone. I highly recommend this product.

    I got this portable charger so that I could ensure that my and my wife's phones wouldn't run out of battery when we are out and about (and in preparation for a vacation trip). Well, I finally got to use it and it is fantastic. While I was in the middle of a call, I noticed that my battery was getting really low, so I connected to the charger. Even while I was using the phone, this charger _quickly_ recharged my phone! Pros: - Fast recharge of phone, - Multiple recharges per charging of the portable power pack, - 2 outlets (one targeting iPhones) that can be used simultaneously Cons: - It's a little heavy, - It's not a tiny thing. - It didn't come with a charge cord of any kind for phones. Trade-Offs: - If I had to carry smaller chargers that added up to the equivalent charging capability, they would add up to more weight and mass. - Since we all probably have _at_ _least_ 1 extra charge cord for our phones, not having one in the package isn't really that big of a deal.

    This pack is portable, just the right size and effective for many different devices. If you are looking for a 6000mah battery pack, I recommend this one.

    I wish I would have had this a month before I brought it when I was standing by an outlet trying to charge my dead Phone so I could record my daughters dance recital. The portable power bank comes fully charged which was great because I used it right out the box. I was a little skeptical about how well it could work for the price. But my skepticism was quickly squelched. Small and easy to use and gives a great charge.

    I was looking for a reasonably small power storage unit for backcountry trips. This one supplies enough power to keep my iPhone charged for a week if I'm careful with my iPhone usage, particularly keeping it in airplane mode when gps signals aren't required. It also charges back up nicely with my portable solar charger for even longer trips allowing me to keep the iPhone handy while the backup unit is getting recharged.

    I have owned and used this battery pack extensively it proves enough power to recharge a Samsung Note 3 and also a iphone 6 with plenty to spare. It's not quite compact but it does pack a lot of power. For the price point you can go wrong with this little thing. *** Do Not Leave this in a hot car! after all it is a battery pack ***

    I got this to charge up my iPhone 6 on the go, since the power demands of everyday use for work and multimedia playback sometimes means that I'll need to charge my phone away from mains power or from my computer. No complaints at all - it's small enough to fit in my pockets and has enough power to charge my phone a few times before the charger needs to be charged.

    This works exactly as advertised. I can get at least 2 iPhone recharges before I need to recharge the battery. It's small, so it's easy to carry. My only "negative" would be that it takes a while to get a full charge from dead, but that's pretty much a non-issue, because you can simply charge the battery overnight and it's ready to go in the morning.

    I purchased this battery pack when I bought my iPhone 6. I had used mophie cases on my iPhones in the past, but did not like the added bulk. This thing works great! yea, it's not as convenient as having the battery built into the case, but it does recharge the phone very well. I have used it to charge my iPad as well. Works like a charm.

    The battery is nice and small and charges fast. It also charges my Samsung phone fairly quickly. I also love the battery strength indicator on the side. Gives a good indication on how much charge it has left. My only wish is that it would have more than 6000 mAh in this little package...but it is good enough for what I need.

    This is a great little charger. It is a little bulky, but has the extra capacity to charge several device or one device several times. I like to go camping, so it is nice to be able to charge my phone or my Kindle while I am out and don't have access to a wall outlet. Gets both my phone and Kindle through a good 4-day weekend with no problems.

    I just bought this a week ago but it's better then any of the other portable charges I've had before.......I got the bigger sized one that can also charge my iPad once and it will charge my phone twice before I have to recharge it. It also holds its charge for a few days between use which for me is a happy bonus.

    I travel a lot professionally and personally and have trouble keeping my cell phone charged. I'm not sure why I didn't buy this sooner! It holds a charge for a long time and powers up your cell phone quickly. So glad I purchased this ... it's been a life saver when I can't access an outlet. I highly recommend it!
