    This review is from: Nekteck 20000mAh Power Bank 3.4A Dual-USB Output Portable External Battery Pack Charger Backup with Smart USB for iPhone, iPad, Samsung Galaxy and More – Black (Wireless Phone Accessory)
    This is very substantial,heavy duty juice pack.It holds enough charger to charge a typical smart phone about three times.
    I intended this as a gift so it was an added bonus that it came in a nice box and ready to wrap.

    Upon first taking this out of the Amazon box,I was surprised that it was a bit heavier than my other portable chargers. It’s not so heavy as to be an extra burden,but it does make it seem like a much more serious battery pack. The entire device is really sleek and impressive. I was giving this as a gift, and it looks even better in person than it did in the photos.

    I already own a charger that has the digital read out charge indicator,so I knew what to expect with this one and it works just as I expected and is very convenient in helping make sure you don’t grab a dead battery pack to bring with you.
    This battery holds enough power to charge my iphone at least three times, and it charges very quickly, a lot faster than it charges in a wall outlet. I will definitely recommend this.

    This portable charger is thinner than most chargers I have used. It’s not tiny, but it will easily fit into your pant’s pockets or purse. The 20,000 mAh will give you a bunch extra electronics to put into your device. For example the iPhone 6 battery is 1,810 mAh, that being said this charger can charge your iphone 10 times. My Ipad 3 has an 11,560 mAh battery which means this charger can charge my iPad almost twice.

    The other unique feature of this charger is charging cable. You get a 3 in 1 cord. 30 pin cable, lightning cable and micro USB cable. You can use it to charge two different devices at the same time!

    The first time I charged the battery, which was almost dead, it took almost 12 hours to charge. According to the very nicely designed manual, this is normal. There are four LED lights on the top of the battery that keep you notified of the charge remaining.

    The casing of the power bank is a nicely finished black aluminum, December 5, 2016

    This review is from: Nekteck 20000mAh Power Bank 3.4A Dual-USB Output Portable External Battery Pack Charger Backup with Smart USB for iPhone, iPad, Samsung Galaxy and More – Black (Wireless Phone Accessory)
    The battery pack is fairly big but packs a lot of juice for its size. 20000 mah is a ton, my iPhone 5s battery is 1558 mah, so this should give me a little under 13 phone charges. The casing of the power bank is a nicely finished black aluminum, similar to the smooth aluminum on apple products. The only thing on the outside casing is the brans this gives the product a super clean and sleek look. The edges of the battery are beveled so that you will not be cut on sharp edges. The bottom of the power bank has some details of the product, it says normal output is 5V~2.4A but the battery pack is able to provide up to 5V~4.8A; I don’t really monitor the output numerically, all I can tell you is that it works. The battery pack will quickly boost your phone to 80% and then ease in the rest of the battery, apparently this is better for the battery in your device. The top of the unit has a LCD display that shows the capacity of the battery pack as a percentage (when it fades the section is matte black), there are also two USB ports to charge two devices at once, there is also a micro USB-in to charge the pack. The supplied charging cable is short, but durable; the cable does not need to be long for this because you will not need to be using it while it’s charging.
