Looks nicer than an external battery

Looks really nice and charges my phone completely. The only thing I don't like is that I can't use the aux cable while having the case on.

I really like this!  Nice design, feels sturdy, and works well.  It plugs in, so it will have a more consistent power source.

So are you looking for a nice high capacity external battery. I you are you might want to check this one out.

This external battery has 3 USB ports something you usually don't see on and external battery. With the 3 USB ports you get a 1amp, 2.1amp, and a 2.4 amp port to charge your devices on. Also the USB Port has smart technology to detect if you device is charged full or protects it from overheating and over charge. Also the external battery will turn on and start charging right when you plug it in to the battery. Sometimes you have to turn the battery on for it to start charging on others.

But one major issue I really highly dislike and it is why I gave this products 4 stars is because the of the flashlight. The flashlight on the external battery mush have 20 different light options on it. Because to turn off the flashlight you have to do threw all of the different options and that takes about 3 minutes to do so. I did contract EC Technology about this and they told me that if you click the power button 2 times fast the flashlight will turn off. That works most of the time but not all the time.  But it would be nice if they included that in the instruction manual. Because that would be something not everyone would figure out by themselves.

Other than that little issue the external battery pack charges your devices really fast and the battery it self charges fast too.  I have had no issues charging any device on it. Ive even used it to work a Xbox One controller without batteries in it. And it stayed on for the entire time I was using the controller.

I would really highly recommend getting this battery. The Flashlight issue isn't that big of an issue. Its just they should have included something in the instruction manual about how to turn it off faster. I also think it would be nice if they included a little bag to carry it in since the size of the battery is oddly shaped but that not to big of an issue.

It's got a solid feel and a nice look.  Plus it's perfect for disabling a battery system for maintenance.  ^_^

This just has the feel of a quality portable battery.  The case fits together nicely, and the battery holds the charge over weeks of no use.  Being able to charge two devices at one time is a plus, and the battery level indicators are easy to interpret.  The included flashlight feature is a nice bonus. This battery packs a lot of power into a relatively small package, and it's good to have when battery-eating devices need to be fed again.

Life remains to be determined since I haven't had it too long & it's still working on the initial charge (don't use it too often). It looks like I'm going to get 4+ hours out of it compared to the old battery which was 2 tops, which is great.

I wish there had been a note about the extra bump on the bottom to provide the extra capacity. While it doesn't bother me at all, and I actually like the little bit of elevation at the back, it could be a problem for others as I have seen in reviews.

A really nice slick looking battery but I do not think it is real leather.  It doesn't have that soft supple feel of leather but more like textured PU leather.  If you are not sure what PU leather is, then let me give you a little info on it.  PU leather is polyurethane covered leather backing.  Basically, they take split leather and cover it with polyurethane and then emboss it with grain or texture.  Technically it is leather since there is real leather somewhere in there but it doesn't feel like 100% leather.  The upside is that it clean really nicely, but it will never have that nice patina that you get with real leather.  The size/form factor is fairly compact which is nice.  The end caps are plastic with a power button on one side.  The button feels ok.  I do not know for sure if it will be durable.

Now the technical portion.  It claims to have a capacity of 6000mah which is enough to charge your iphone 6/6s about 2-2.5 times and about 1 fully charged ipad.  There are two usb ports that output both are 5V, one port is 1amp and the other is 2 amps.  There's a 5V/1A micro USB charging port and there is a short cable provided for charging.  They do not include a charger, but I can plug it into my phone charger or computer.  It has a smart charging feature which should prevent it from over charging.  Li batteries are very dangerous if they are overcharged.  It's nice to know there is a safety feature so that it doesn't blow up your desk.  Li batteries do not hold memory so that you will always be able to get a full charge into it until the battery starts to fail.

I have seen 6000mAh batteries in smaller and lighter form factors but not at this good of a price.  It comes nicely packaged in a black box and would make a nice little gift/stocking stuffer for that person that needs to alway have a fully charged phone or tablet.  The photo I have attached is my hand holding it so that you can get a sense of size.  I have small hands and it fits nicely.  If you're a golfer, here's a point of reference, I wear a size small Cadet glove.  I got this for my wife to keep with her in her purse so that she can always have power when needed.  The new iphone 6s drains really quickly and you almost need one of these if you want to use your phone all day.  I got a discount on this and think it was a really good price.

I will let you all know what the long term result of frequent use results.  I would have given it 5 stars if it had come with a charger, the power button felt more durable and if was genuine 100% leather--however, don't think it would have been as cheap.

When the Droid Razr first came out, the biggest concern I had was the battery life, since 4G sucks it down and the early reports suggested that it might need recharging during the day. I looked around for an alternative solution and I found it in this product -- an external battery. It tethers nicely to my phone, with both a short (3 inches) or long (about 2 feet) cord. It takes a little longer to charge than a wall outlet, but more importantly, it continues to charge while using my phone. Form-wise, the external battery looks very nice, smooth with rounded edges -- and isn't particularly large, about the size of a soft pack of unfiltered cigarettes. So it is easy to carry with me all day without being obtrusive. I would recommend this wholeheartedly to anyone who worries about their phone's battery giving out during the day. I am glad I found it.

It is beautiful!  It really adds some style to the camera, but it makes is difficult to remove the battery to recharge, something that you need to do often in a trip. (Honestly, I don't think it is possible to to have a cover that doesn't get in the way of removing the battery.)

Looks sleek and feels good when you hold. It came with a small pouch, USB Cable and instruction booklet.
I left the power bank charge overnight, and when I connected to my phone the next day, my phone displayed the same duration for "time left to charge 100%"  between the wall charger and this power bank. So, I assume it outputs the same power level as my wall charger.
 I hope the power bank retains the power level after multiple charging and discharging cycles.
Oh the last thing is the flash light, which I initially thought was a power indicator, is super bright and its certainly handy.

It's so looking nice and works well. But the connection isn't good quickly when it doesn't have enough battery. The sound gets annoying. So I have to charge it frequently than I expected.

A compact, solid-feeling powerbank with a rubberized exterior and a decent capacity. It's nice looking and has a better charge/discharge rate than many early-generation battery packs.

99Digitals has gone for simplicity in this USB battery pack: a minimalist design, one output that delivers the battery's maximum output, a 4 LED capacity gauge. A short, flat USB to microUSB cable is included. There's an easily overlooked low-lumen "flashlight" LED that's too dim to be useful, and a power button.

Charge and discharge are both decent, with the battery drawing 5-6W (at the wall) when charging. Charging a connected device is brisk, with my LG Nexus 5 topping up as fast as it does from its native AC adapter. This is better performance than many USB batteries I've tried, and superior to many USB hubs. Even allowing for power lost to overhead, the 7800mAh capacity is enough for 2-3 full charges of the typical smartphone's 1800-2300mAh battery.

The no-skid ribbed exterior is a nice aesthetic variation from the usual battery, but the matte black finish keeps the rubber from looking cheap.

In today's mobile-centric world, it's important to keep devices charged up. But depending on wall-power or car adapters can mean a lot of plugging-and-unplugging-- short charges that are bad for battery longevity, and ineffective at keeping a good charge (unless you're willing to be tethered to the wall for an extended time). With a USB powerbank, you can just take the power source with you, unplugging when the device is done charging up. I keep a USB battery in my vehicle, office desk, and in all of my commonly used travel bags.

The market for USB battery packs has become quite saturated. But this unit, with its compact minimalism and solid power performance stands out. Recommended.

Decent alternative to carrying around a secondary internal battery since many devices have internal batteries that are not easily or quickly accessible anymore. Good for on-the-go charging and battery life extending.  It seems to do well keeping its charge when not used for several days. A color coded LED indicator activated by a button on the pack itself indicates the current charge level (Green = charged, Blue = medium charge, Red = low charge/needs charged). My wife will have it when she goes on an MOR cruise later this year.  I'm sure it will serve her well.

This is the first external battery pack I have owned, and from the unboxing to usage I was very pleased.  The battery pack is well packaged, small and aesthetically pleasing.  I really like the blue color and the texture of the outside.  It fits well in the palm of your hand for size comparison.  The unit I received was mostly charged so I only had to plug it in for an hour or so.  One BIG plus about this unit is even if you left it sitting for a year it would still have 80% of the juice remaining.  I take it to the beach w/ me to power up my phone after streaming musing for awhile or just keep it in the car most days for an emergency situation.  Overall, I definitely recommend this product.

I really like this battery. I bought a small power pack for my husband last Christmas, and I've wanted one of my own ever since. His is a small round one, about the size of a roll of Life Savers. This Lumsing is definitely bigger. It's slightly smaller than an eyeglasses case, and half as thick. At first, I thought this thing was huge (compared to my husband's tiny charger). But then I realized how many charges I could get out of it, and it's totally worth the extra size. I bought the 10400mAh power pack, and I easily got 4 full charges on my MotoX (about 2 years old now, I think). And these weren't idle, I'm-setting-the-phone-down charges. A couple of times, I was playing games and browsing the internet while it was charging. I think it takes about 2 hours to charge my phone from almost dead (<10% battery left, sometimes <5%). I can just pop the battery and the phone in my purse before I hop in the car to go somewhere, and the phone has half a charge by the time I get there.

Aesthetically, I really love how this looks. The sleek black with the silver looks very nice. And I appreciate the round shape on one end - makes it easier to stuff into my purse. The design is good. (Yeah, a lipstick-sized battery would be the best, but you don't generally get that much power out of a tiny power pack.)

This thing is so handy to have around. I'm heading out of town in a couple of weeks, and I will be so glad to have it with me on my trip.

This portable battery is phenomenal in function and looks.
Not bulky or hefty. Easy to use with 2 ports and an easy to find large power button on the side.
The color indicator on the label name is a great touch. White, green, red for fresh, ongoing, near dead.
Only thing is the cable it came with is pretty short making the user have to haul the battery next to the phone when using it.
I have a medium-large size hand, so it's comfortable to hold below the phone. Unsure if it's easy enough for other users.
