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.

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.

Does what it needs to do, option to charge two devices at once is a plus. Charged my iPhone SE from 20% to 50% in around 30 min. It raised the temp of the battery during charge so I stopped the charge at 50, not sure if its an issue or just the amount of output power into the device. The look and feel of it is good but it shows your fingerprints easily, a full green ring for indicating a full battery is nice and bright. It is in the large size and heavier side, its better to keep it in a bag or backpack if you are on the go.

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.

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.

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.

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.

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.

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.

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.

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.

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!
