Customer Ratings & Reviews

I have an iPhone 6S and haven't had the battery changed yet, so it tends to run out of juice faster than I would like. As I was getting ready to fly out for a big 5-day sales meeting, I decided it would be a good idea to invest in a portable charger. Luckily, the Best Buy "Deal of the Day" just happened to be this Tzumi - PocketJuice 20,000 mAh Portable Charger, and for less than $20 dollars, it seemed worth a try. I'm glad I did! First of all, the capacity is huge at 20,000 mAh. According to the packaging, I should be able to charge my phone about 11 times - although I would say it's more like 6-7 full charges. It's a little larger and heavier than I expected, but it's still small enough to fit into a suit jacket pocket. It has 2 USB ports, so I can actually charge 2 devices at once such as my iPhone and iPad. I would say it charges my phone at about the same rate as my wall charger. The on/off button has lights around it showing how much charge is remaining, which I find really helpful. The device itself takes up to about 15 to reach a full charge, and the only cord that comes with it is a very short USB to mini-USB. No "wall wart", you'll have to provide your own or plug it into the USB port of a computer to charge it. Overall I'm very happy with it. We'll see how well it holds up over time.

I can charge my iPad twice and my phone 3-4 times before having to recharge! It's a heavy unit, weights more than my phone! (iPhone 6 plus). Has two ports so I can charge two thing at the same time! Great product!

I purchased this power bank due to size and price. Comfortable size considering its 20,000 mAh. Can charge two devices at the same time. Would recommend for storm outages, road trips, camping, hikes, or traveling by air. Being usb, you aren't committed to one type of devices. You can charge your iPhone, micro usb, Type-C, GoPro, tablet or anything else that has a usb plug.

We needed additional battery power for 2 Kindles on a 3+ hour flight. This pack worked great. Powered 2 kindles for the flight and had about 1/2 battery to spare. One of our Kindles holds absolutely no charge so one relied solely on the battery pack. As for the pack itself, it's small and lightweight, lighter than expected. It has an indicator light that shows how much battery is remaining. It has 2 USB outlets so it can power up to 2 items simultaneously. Recharge time depends on the charger but using a high power charger it will fully charge in about 4 hours or so. In short, it was well worth the money. I would recommend it highly.

Love that y can get several charger for your iPhone or iPad. Also works to keep DSL camera charged when taking a lot if video. Only down side, beside the weight is the fact that it only comes with a charger cord and not a plug to put into outlet. Cord is also very short so charging my be awkward using normal outlets.

I bought this for 15 bucks and it has worked like a charm. 2 USB ports I can charge 2 things at a time plus this thing charges my phone fast.

We had power outage so next day went and got this charger because it has dual ports and will last a long time.

This portable charger, while it takes awhile to charge will charge my iPhone at least 4 times, more quickly than my wall charger. With 2 USB ports it’s great for travel/

This charger is definitely worth it! I picked one up as a Deal of the Day and was skeptical as I have tried other chargers and they would discharge during storage and would be dead when you needed it. Not this one. Plus it’s got two USB charging ports and enough juice to charge two iPhones phones at the same time. Great on those trips to an all day amusement park. I loved the one so much that I bought two more to give to my kids for their book bag. Don’t miss out on this great product!

I saw this on sale for around $25.00. At the time that was the cheapest 20,000 mAh external battery available at Best Buy, so I purchased two. The size is very reasonable given the power rating, It has two USB ports for charging and I can say they are very fast. They're rated at a max of 4.8A, but I'm not sure if that's for both or each. I'm not sure what the price is currently, but for $25.00 I can highly recommend.

I purchased the Pocket Juice 20000 mAh for a recent overseas trip visiting close family and it was exactly what was needed to keep my teenage sons phones charged. Each phone was able to get at least 2 full charges from it and it was still showing that it had 2 lights of power left. Needless to say my sons were not complaining as with two USB slots they were able to plug in and charge at the same time.

So far so good.It is a bit heavy and the cord they give you is too short. It will charge my galaxy at least 5 times and with 2 usb its a plus.

I bought this charger for my daughter so she has no excuses for having a dead cell phone battery. It will charge her iphone and iPads at the same time. Absolutely love it!!!

Heavy, big, but it can charge multiple devices on the go.

This 20,000 mAh provides hours of instant power at your fingertips and ready to go wherever you are. This unit has been capable to charge any usb device that I currently have up to my Nintendo Switch on a single charge. This is a must have for basic everyday needs especially if you plan on doing any traveling.

Has tons of power for multiple phones and tablets. Quickly charges everything. Nice addition of lights to tell you its charge. Has usb connections and also comes with a usb charging cord.

Not only use it to charge our phones, but also use it for small speakers, laptop and tablets, love it!

Great charger. Would recommend to anyone needing a charger that had more than one charge to it. You can charge more than one thing at a time. Great for the price

Charge it over night and last two days and has dual chargers so when we are out we can charge a couple of items at the same time and this provides a quick charge too

Awesome power bank, Lights on top to indicate how much power is left. 2 usb ports to charge multiple devices. Lights also light up room at night.
