Customer Ratings & Reviews

Bought two of these during "Deal if the Day" promotion in preparation for a week away in vacation to a Disneyland. Charger was a great way to keep all of our phones (5 in all) charged through out the day. Only had to recharge the battery pack once or twice during the trip while allowing us to charge our phones from empty each day. On average, recharging one phone from empty to full would only waste a quarter of the overall recharger overall capacity. The charger is big and heavier then most but you will always have a charged phone. Would definitely recommend it, specially for the $17.99 price advertised during these deals.

Make sure to only recharge it using the included cable - this ensures a shorter distance between delivery of electricity for the battery. Ensuring safety from anything related to a fire hazard. Allows you to externally power and charge USB-A male cables to devices, two at a time. USB-A to USB-Type C(Android), USB-A to Lightning for iOS(Apple) and any other USB devices, such as wireless headphones, flashlight, digital camera that charges with their USB ended cable. Usually charge mine up and it can take 8-12 hours to be honest. A solid green circle indicates a full charge. 20,000mAh equals MULTIPLE full charges. iPhones typically run 2000-2700mAh I've taken with me on road trips, Pokemon Go, a day at the coffee shop. I usually keep it charged and in center console in my car for on the go power.

Bought 2 of these and received on good condition. In full charge, we tried plugging a runnibg iPad to it in prep for our camping and works for almost a day. I didn't wait til it drain out and I'm good with it. I put only 4 stars as I wish I could charge it faster... takes about 4 hours to charge.

I like it a lot. Keeps my stuff charged all day. If I was still playing pokemon go, all I would need at my pokestop is this, a mobile food delivery app, and a bucket... to sit on!

I thought this to help extend the life of my iPad Pro to get through a full day at college taking notes with my Apple Pencil via Bluetooth. This did a great job extending the battery. It charges relatively rapidly at night when I’m charging my iPad. Really my biggest problem is that it gets heavy after a while in the backpack, and perhaps that it’s kind of bulky an unruly on teeny tiny college desks when I’m trying to recharge the iPad. I wish I could get a give this a 4 1/2 But I had to choose one or the other, so with my two very minor not even really complaints I rounded down to 4.

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.

Amazing portable charging bank! I compared this one to quite a few others before ultimately deciding upon this one. It charges up to 2 devices at once, holds 11 smartphone charges//20,000 mAh, and is quite sleek. It is a tad bit heavy, but not crazy heavy. If you're looking for something really light, I would recommend getting a smaller charging bank. I absolutely love this one, and it suits my needs and has exceeded my expectations! 5 stars! Thank you!

It charges dev quick and durable. The product is bigger than a iPhone 6+, it takes the battery around two days to fully charge. Its heavy and bulky but holds charge for a long time

The 20,000mAh charger quickly charges your smartphone (haven't tested it on a tablet). It's portable in size, but it does have quite a bit of weight to it.

Bought this because it was on sale and less than other power banks with less mAh. Honestly, wasn't expecting much from this but it surprised me with how quickly it charges and it lasted at least 6 full charges between my iPhone and iPad. It is a bit heavy and bulky but that's expected for a power bank with 20,000 mAh. Ideal for traveling!

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 can fully charge my iPhone7 Plus 4+ times. The soft rubberized finish is attractive and the shape fits nicely in an inside coat pocket, or small backpack pocket. It is a bit heavy, but if you want a true 20,000Mah then this is it. It takes a while to fully charge, but it's worth the wait. .I charge once a week and keep it with me everywhere I go now.

This is a great backup battery for charging mobile devices. It is a bit bulky, but it packs a lot of energy and can recharge my phone about 3 times before needing to be recharged itself. It is simple to use with only one button. One click to turn it on, and two to turn it off. It could not be simpler.

The Tzumi PocketJuice 20,000 man Portable Charger packs the punch with quick charging. I wanted a reliable charger that I could get several uses out of, this does just that. I have wasted money on off brand less powerful chargers to only be disappointed because they work a few times before dying. If you want quality and something that will last a long time, go with the Tzumi. I only found 2 very minor flaws - it does not come with a case and it's heavy when carrying it around. However, the sense of knowing I can get a quick long charge outweighs these very minor flaws.

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.

Recharges the IPhone 6 with good speed. There are quite a few recharges of the IPhone 6 in the PocketJuice. Recharging of the PocketJuice takes quite a long time. The PocketJuice is quite heavy and takes up a lot of room in your pocket.

This battery is fantastic! I got it during one of the deals of the day - it definitely doesn't disappoint. Large capacity and you can charge two devices at a time - it worked for us during a Disney vacation.

I purchased two of these on deal of day after reading several good reviews about it. It charged my iPad from 5% to 100% in a couple of hours and still had a half charge left on it. It has been extremely useful in charging devices while children were watching movies on our devices outside of house/vehicle. The only con for some might be the weight of the product, as it is a little heavy, but this doesn't bother me any. I just throw it in my purse on my way out the door and never have to worry about any of our devices having dead batteries while on the go.

This power bank is unique, powerful and super fast. Excellent for emergency purposes when you are away from home.. I really love it and I use it a lot.. Can recharge any phone up to 5 times before it gets to the low level..

A little bigger than I expected, but once this unit is fully charged, it should last you through out the week. Definitely 20,000 mAh, and charges fairly rapidly. I strongly recommend this power bank
