Customer Ratings & Reviews

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..

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.

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

Great source of external battery power is packed into this, relatively, small, package.It is kinda bulky, and a bit on the heavy side if carrying it in a carry-on, but convenience of having 20,000+ Mahs on the go is worth it. Works seamlessly by simply connecting it to your device via USB micro cable. The only nuances I have is that it takes a long time recharge it. It came half-charged out of the box, and took overnight to charge the other half. Also, you can't recharge while it recharging another device. Other than that, 5 stars!

In my hunt for a portable charger, I came across this one. Everyone liked it capabilities, but it was too heavy. It is heavy (adds to my daily work-out), but it delivers as promised. With 2 charging ports, I don't fear running out of juice for any of my devices. The rubberized exterior is great for knocking around my bag. It holds its charge, so I don't have to be concerned it will be dead when my other devices are. It is a real deal, compared to other chargers at similar prices.

2nd Battery backup of the exact same model/brand. Got 1st at decent price but not like this 1 went on Sale. Great backup for iPad & iPhone 6s+ & still had plenty of juice left. It does take a lil bit of time to recharge But it’s not a problem if you have 2 like myself. It is kinda heavy but I’m guessing since it has a huge capacity then it gets a pass so get 2 & workout your arms, lol. I definitely would recommend it & when on sale., get it...! I would of given it a 5 Star rating if not for the weight & charge time....

I love this charger. I only bought because of the hurricanes. At first I didn't know that I needed to push the green round button for the charge to work, but now it works like a dream. IT IS HEAVY. I only need it for emergencies, so it works for me.

After using a smaller power pack by this company I decided to try one of larger capacity. This thing lasts a long time! One charge and you'll have multiple days of recharges for your phone. Of course such power comes at a price: the device is rather heavy and perhaps a bit longer than is comfortable to carry in hand or pocket. I still greatly recommend it though if you're going to be away and need the ability to charge your devices. Would be a great asset for a hurricane supply item.

This thing is great for traveling. I also rubberband to my tripod and it keeps my 360 camera going for an entire wedding on a streamline recording. It does take all night to charge, but it is a big battery. For more money there are others that allow duel charging. This one does not have that option. Also, you CANNOT charge the bank while the bank is charging your device. The price i got it for was good, so not going to complain about the other features. Just plan ahead amd dont forget to charge it. It has enough juice to last a few days if you just charge youe device a fee times a day.

During a long flight my phone just ran out of power. I decided to look into a portable power source. The Tzumi was on sale plus we had rewards to spend. The unit is large and has some weight to it. The trade off is the amount of charging it can produce. On our last cross country flight the Tzumi kept 2 phones and a ipad going. Made the flight a lot easier to deal with. It does the job as described.

I bought this portable battery for a Christmas gift, so I do not know how it works. I would say that it is fairly large and heavy. I`m not sure how "pocket" it really is. I`m not sure if the person I`m giving this to will keep it or not.

This charger is capable of charging my devices before needing to be charged. A bit large and heavy to be carried around in your pocket. Overall very easy to use and extremely long battery life.

Charged my phone quickly from 1% to full in an hour. Still had 3/4 Charged left on charger. Bigger than a cell phone and heavier.

I got this battery charger to keep my phone charged for a 10 day trip and for future camping trips of up to a week long. It charges my Samsung Galaxy S7 Edge multiple times before needing to be plugged into the wall. I've never seen it less than 3/4 full of charge after fully charging my phone two or three times. My only complaints are about the size and heft, but I expected it to be bulky to provide the amount of capability it has.

When I purchase a battery pack, I always look at the battery size by milliamps. This is the going to be the best bang for your buck. Works wonderful and will charge my 12.9 iPad pro quickly

Best portable charger I have ever purchased, and I have had several over the years! It’s lightning quick and it charges my phone several times before having to recharge it. It’s a little on the heavier side, but worth every penny...you get what you pay for! Would definitely recommend this charger to anyone and would purchase it again!
