    Great Product

    Great for on the go recharging. I charged two iPhones (separately) four times and it went from 100% to 93%. They were not completely dead but let’s say from 20% to full charge. Might have given 5 stars but the description is not right. It is a 12,000mah battery pack not the 20,000 as stated in the description and there is only one QC 3.0 port not two. Not even sure what the benefit is for having a Qualcomm port other than it is .6 A more than the standard 2.4A. Makes me wonder if “quick charging” negatively affects battery longevity, it’s like charging your iPhone on and iPad charger. The product is a little different than the photo as well. Overall it worked great, took it to Disneyland for a few days and kept phones charged very well. Keep in mind the bigger the portable charger the bigger and heavier it will be. This is about the size of two iPhones stacked together but when you have kids and several phones to keep topped off this works great.

    Great Power Bank

    This is a great power bank. It charges up my iPhone really quick. I love the digital display that shows the anoutyof power you have left. The only reason it is not a 5 star review is because of the short usb charging cable it comes with. I believe it is a usb 3.0 cable and only works with those to charge the power bank. I tried a longer cable I had laying around the house because it was easier than having such a short cord attached to a wall plug after an hour the charge stayed the same. I thought it was the power bank itself until I used the short cable included and it started charging back up pretty quickly. I can see the short cable being an issue after using it for a long time but other than that it is a great power bank for your charging needs.

    I've purchased several of this type of item for my daughter, who never seems to be able to keep her phone charged. What attracted me to the PocketJuice was the digital readout. The batteries I've bought in the past had a series of lights that indicated the battery life, and I found them inaccurate. I've used this for a few weeks now and am impressed with how quickly it will recharge my Samsung Galaxy S9. It's almost as fast as the quick charger that came with the phone. And, it takes a very small "bite" out of the capacity of the PocketJuice. However, when I used it to recharge my iPad Pro, I found it to be much less effective. On a series of one, the PocketJuice drained very quickly, and the iPad charged minimally. I'll be repeating this test in the future.

    Very Good Product this far

    I really am enjoying this pocket juice thus far. I have only had it for a month or so and it works like a charm. I am able to let the kids (2 of them) use the phones while it is charging and my battery wont be completely dead. One child uses my phone and the other my wife's phone. They use the phones while letting it charge (by using the pocket juice to keep the device charged). I love it because we can take it in the car, grocery store, restaurants, parks or where ever we go. Would buy it again. It can also charge tablets or anything that has a usb. It can charge 2 devices at once.

    Overall this is a good portable charger, but it has a few weak spots. The bad, it appears as though it will only charge with the short cable that it came with, I tried with a different cable with no results. This limits the convenience a bit. It doesn't allow pass-through charging either unfortunately. The good, it holds a ton of backup power which makes it good for multiple charges. It also charges quickly which is a big plus, and with USB-A ports it can charge pretty much anything. Overall, I would recommend this to someone looking for a quick, backup charger.

    I bought the Tzumi charger for use with my android. Phone less than a year old and battery power not enough to stay charged more that an hour. This charger allows me to use my phone 8+ hours for work. It tells me how much of the charge is left. I can use for approximately 21 hours before I must recharge. Comes with a very short cable, but you must purchase a plug for the outlet. It is heavy compared to other chargers. I purchased more for gifts.

    battery indicator is useless

    I purchased this charger because of the digital battery indicator. It was useless. I cycled through a few times to make sure it wasn't a fluke. Typical charging pattern: After charging a device, the charger still showed 100%. After using it more, the battery showed 77%. I plugged in my phone (which was at 40%) overnight. The next day, the charger is at 0% and my phone is only at 70%. I ended up returning it.

    I love this device, it's the next best thing they have created since the Cell phone. Using my phone all day or multiple errands the battery runs low. Sometimes I have to run out at night and with my Pocket Juice, I can connect my battery and have a working phone. I love it, it's my extra sense of Security.

    CES 2019 proven

    I just got back from CES 2019 and relied on this portable charger to keep me going the whole day. The charger went the whole week without the need for me to recharge it. I used it primarily to charge my Android phone. The Qualcomm Quick charge worked as advertised and quickly charged as I was walking the show floor.

    Great backup power source

    I bought this for my trip to China. I needed a backup power source for my phone and gopro. When I depleted my batteries I would recharge them quickly throughout the trip. A must have if you're planning on taking multiple videos / pictures and don't have a reliable source for recharge. The digital display is great for telling you how much you have in the tank.

    I got this because I was going to travel out of the country and will be using my phone a lot. At first I was skeptical of how many charges it can hold even if it says 10,000mAh. But when I used it, it really did the job! I was able to charge my phone around 3 times before I plugged the power bank and charged it as well. I'm really glad I got this one!

    I originally bought this for my fiance but she says it is too big to keep in her purse. So her loss is my gain. I have used it a few times when I'm on the go and my phone battery is getting low. I can connect it to my phone and it charges my phone pretty quickly.

    I purchased this charger prior to an overnight backpacking trip with my teenage son. I wanted to be sure we could both charge our phones and my Apple Watch once we arrived at camp. Not only were we both able to charge, but I still had 85% charge left.

    Without doing a power analysis, my subjective experience with using it is that is lasts a very long time under heavy load (2 amps ). The connections are solid. The display on the digital readout of percent battery left is very useful. (it displays digits 01 to 100)

    Everything should be moving to USB-C at this point. Too bad this sticks with micro usb and lightning. However, if that's already what you have, you can't go wrong here. High-quality, well built. Should last you a while.

    Because it costs less than some power banks that have half the mAh, I thought it must be made more cheap. I was surprised that it’s actually well made and can charge my phone rather fast multiple times. I use it for Pokémon
