    Very good product, but good definitely be better.

    So this is my first big portable battery, by big I mean both size and having more than one charging port. It was cool that it was mostly precharged out of the box, but a friend recommended to charge it to full capacity to ensure longer life from it and a better ability to hold a charge later down the road. So there's a few things are knocking this down from a 5 star product to a 4 star. First, price. OK $35 is reasonable, but compared with $5-$10 for smaller ones, it's a lot, even given that it's a much bigger battery. Second goes hand in hand with being a big battery. I love the capacity, but I'd like it to come with a longer charge cord. I get that one doesn't generally need a real long one, but this one that comes with it is literally less than 6 inches long. It's almost useless it's so short. And those who shop around know that a 3-6 ft cord ain't cheap. This is just a way to squeeze more money out of consumers. A plug in power adapter would have been nice, but I can also see why they didn't include one. As far as performance goes, it is a bit slow to charge things, but amidst the mixed reviews I've read I personally have had absolutely no real issues with this in terms of performance. Would absolutely recommend for someone looking for a big, yet portable battery on a modest budget. Just expect to use your own charge cord or shell out for a new one, cause you can even tell by looking at it in the box that what comes with it ain't nearly long enough. Other than that though, I absolutely love this.

    The charger is good, accessories not so much

    The science is good, but it's what's missing is a decent cable and wall charger. The portable charger is great so far after a few weeks of charging. It's dimensions are nearly the same as an iPhone 6 stacked two high and I'd say it feels solid. It was a good price for a 10,000 mAh lithium polymer battery. I love the dual ports and I love the 3.4amp charge capability I have a few irks that brought the score down... - The cable. Cable is just over four inches of worthless. I don't even know what they were thinking. I just threw it out, it's too short to use anywhere. There is no wall socket included. I would have been happier getting a wall socket and no cable. - Since you'll need a charger MAKE SURE you get at least a 2.1amp charger like the kind for an iPad NOT the teeny 1amp charger that comes with an iPhone. The reason is obvious...it already takes HOURS to charge, you will wait hours longer for the latter charger. I had the needed cables but I gave it three stars since a not so techy person would have to go out and buy their own on top of just buying their new charger. I would still buy it again and I would give it as a gift (with accessories)

    My phone now lies to me about how much battery life is left. I got this to give me a few extra hours on the phone at the end of the day. Now I find I need to recharge the phone multiple times per day. This allows me to do that wherever I find myself, whether there is a power outlet available or not. 4 stars, because there are a few odd quirks. Once, the device seemed to be discharging while not connected to any device. I connected the the power output back to the power input and that stopped the issue. It still works so I didn't break it. This worked because (apparently by design) the power output shuts off if the power input is connected. Bonus, two charging ports, so you can charge your phone and tablet at the same time. Pack can fully recharge my devices at least three times before I need to recharge the pack. Warning: LED lights are really bright, so maybe you want to charge the pack in the office or the kitchen rather than the bedroom.

    Just got this item (pocket juice 10000 mAh) last week. Was a little unsure about the quality and performance as reviews are mixed. So far have used it a couple of times, charged an iPhone 6 in full in about 2 hours from 18%, iPhone 3GS took more than an hour to charge 25% - so clearly the speed has a lot to do with the type of device. Battery level in pocket juice didn't change after charging these two devices so assume there's plenty left over to provide more charges. The battery was 3/4 (indicator light at 3 bars) charged out of the box. Took another 2 hours to charge it to 4 bars (using a 5.1v iPad charger). Not sure if all the lights will stop blinking when fully charged - I disconnected while the last light was still blinking as I didn't want to overcharge it. Used the attached micro cable to charge the battery. Have to say the cable is super short making it difficult and awkward to place the battery in a level place while charging. Why couldn't they include a longer cable?

    I had an older model of this that was 20,000 mAh that was recommended to me by as associate at the store. I loved it. Sharing it between the 5 people in my family was easy, charging 2 devices at once. Then my daughter started taking it on college volleyball travel trips. (I think she took it to about 8 trips before having to charge it again.) Because her schedule conflicted with mine a few times I decided to get another charger, smaller this time. It's just as nice as the first one. These seem very rugged, and I was able to take this one on a plane. I highly highly recommend it. Keep in mind that the little cable that comes with it for charging it is very short and has no "brick." USB on one side, mini USB on the other. This is slow to charge itself, but once charged, devices you plug into it charge quickly.

    My poor little Smartphone is at the end of its life. Unfortunately I am not ready to upgrade as I am waiting till next year to purchase the Galaxy 9. What do I do when I cannot even get through the day on my Galaxy 6 where the battery is built in! I purchased this charger to take on vacation. In testing it out, I managed to get 4 charges from it. I would plug my phone into it when my phone hit 20 to 30% battery remaining. Now I have confidence that when I go on vacation that I won't be left without a charge on my phone. I won't lose contact with friends/family and still be able to use my GPS to navigate the big city. Although this battery is heavier than what I expected, the Best Buy salesman assured me this brand was the best one on the shelf. When I re-charged the battery pack, it took less time than the instructions stated. I would recommend this item.

    A charger worth having while traveling

    This portable charger has been used on my Samsung Phone & Apple iPod. There are 4 bars and I would estimate about 1 bar would fuel my phone at the 60% level with a bit to spare for the other tech ware. At the 30% level at full charge about 3 bars would fuel my phone. The Ipod doesn't express levels like our phones and tablets so I can't estimate. I can say I had my Ipod down to 25% and it took almost all bars on the charger to fuel it to about 80%. It's not expensive but it's not $19.99. I got mine on what best buy considers a "sale". It impressed me enough that I gifted one to a family member.

    I purchased this product because, I'm normally out the house & away from an electrical outlet during the day & needed battery recharging inbetween. I totally recommend the Tzumi - Pocket Juice 10000mAh portable charger. The battery isn't heavy like higher mAh battery packs. It's light enough to carry in your purse or pocket. And you can get about 3-4 full charges out of it. Only con I have about this product is the short usb charging cord that comes with it. You definitely would need a longer changing cord especially if your using ur phone while charging (which I don't recommend) cause it charges a lot slower.

    This model is optimized for Apple products, with two USB ports, a Lightning In port, and a numerical digital readout of charge remaining. For those fretting about Apple battery capacity and condition, this charger making concerns and criticisms non-issues. You won't care if there's no wall or car charging outlet available for hours, you won't care if shills for competing device companies tout their argument that internal battery size of Apple products is a fatal flaw. Using the PocketJuice you'll have plenty of reserve power for multiple devices, in a package that truly fits in a pocket, as its name suggests. Just be sure and follow the manufacturer's admonition: don't drop it.

    I don't have a lot of experience with these. But this charger has worked great since I bought it. Being able to charge two devices at once is a plus. I went to dinner with friends and someone brought a plug and usb cable hoping to find a outlet behind a bar. I pulled this charger out and I would guess 2 cell phones at less then 30% power charged up to 100% in less than an hour. Could have been sooner as I never checked. But both phones were being used the entire time. It is thicker than a cell phone but shorter so it easily fits into your pocket. My wife's phone is always 30% or less before going out so we take it everywhere.

    I just got home from Best Buy with my Pocket Juice Portable Charger. First of all, the box was harder to open than it needs to be. But the bad news is the charger includes only a 3" long MINI USB cable. What am I supposed to do with that? The charger does not come with a wall charger and only accepts a FULL SIZE USB, but not include. I own a handful of devices, all use a MINI USB. What you will need to to charge the charger is a wall charger and a cable with FULL SIZE USB's on each end....who has one of those laying around? Between myself and my two sons... none of us have such a cable. It should have been included instead of the useless 3" MINI USB.

    I bought the battery to be with my church youth group for a very long day and I knew I wouldn't be able to charge up. On the way to the event (3-1/2 hour drive), I started to top off my battery, but the included cable was woefully inadequate. The cable is cheap and does not make contact with a Galaxy S5 Active phone. I tried other "cheap" cables almost identical to the one supplied, and they did not work either. On the way back, with my battery at 20% and 3 hours until home, we stopped at a truck stop and I purchased a 6 foot cable that worked like a charm. The quality difference between the two is night and day. I would hope the cables would be a little more robust in the future.

    This power pack is wonderful and especially helpful for traveling. Charging stations in airports are usually crowded and extremely unsanitary/gross. This allows you to quickly power up anywhere and your phone won’t die if you are reading/viewing a lot of content. Love this purchase, and I rarely leave home without it. My only complaint is that the charging cable for the device itself is WAY too short, but I work around it by charging with my nightstand. Great buy overall, and small enough not to add too much bulk to a purse. Just remember to get and carry an extra cord that connects your phone to the pack.

    Great Battery Pack

    The battery pack holds its own, the only downside being the very short charging cable it is provided with. They give you about a 1inch cable which is high enough ampage to charge the battery pack or your devices and I found this to be very inconvienient. The cable shorted out after about 2 weeks of use. You will definately want to invest in a high amp charging cable to go with it. Some cables you will find will only handle about 1/3 of this battery packs output capabilities so it is definately a good investment and good idea to keep in mind. Otherwise great product, works as advertised.

    I play pokomon go with my son, and this product helps to keep my cell phone charged for hours. It's also great to have because I'm constantly forgetting to turn off my cell phone or charge. I have a special needs child and always need to have a way for the school to contact me. I love this charger, it keeps my phone ready to go, last a long time but remember to check, if you leave it for a certain amount of time, the power can drain so if you know you're going to be out all day, charge it the day before to make sure you get full use the next day.

    Had to settle for this portable charger since Best Buy stopped selling insignia chargers. I bought an insignia 20000 mah charger for $20 something a couple years ago. Was hoping to score again, but they stopped selling that brand. So this was the next best bang for your buck portable charger available in store. Obviously doesn't last as long since it's only 10000 mah, but it worked fine for what it is. It's a good back up charger. I didn't keep real good track of how many charges I got on a full battery since I was on holiday in Iceland, but I would say I charged my phone here and there for about 3 days before the battery ran super low.

    I bought this power pack because I had a rental car that needed the lighter type adapter and I was going out of town. My son had borrowed my mophie and I didn't want to end up on the road with no juice. One of the Best Buy employee told me that this works the same way and even better than the mophie because it cost 3x's less than the mophie. I decided to give it a try since I already had the power station xl mophie. After trying this in my opinion this charged my iPhone 7 faster and I had about 5 charges to it. I was really impressed with this powerjuice. Needless to say I'm now using this charger and let my son keep the mophie. :)

    This is my second Tzumi, same size. Still using my first one without issue. My friend broke my smaller more pocketable Mophie and replaced it with another Tzumi which I appreciate! I take this on my out of town trips and have really appreciated the convenience of its portability. Instead of having wires coming from every orifice of my car, I have 1-2 of these working in my backpack or cup holder. No issues and great charging.

    Having just returned from Asia, I can attest this little gem worked as advertised providing additional needed power to my iPad and android mobile phone. Please note airport screeners at Far East airports are checking lithium battery ratings in compliance with the UN International CIvil Aviation Organization (ICAO) hazardous materials guidelines restricting lithium-ion batteries on-board aircraft to 10000 mAh (100 Wh) per battery. I am so glad I purchased this unit just prior to my trip and left my 20000 mAh power bank at home!

    I had to get this because my power went off for almost a day during our first snowstorm of the season. And it charged my phone nice and though not as fast as wall outlet but fast enough and I could use it just fine. And now i have it to take with me wherever I go and if my battery is low I won't have to turn any apps off and al that stuff that you some times do to save battery life when it is low
