This is my 3rd portable charger but my first pocket juice. I use my other 2 chargers for my phone but i specifically bought this because of its usb-c port for my ipad pro. It's not as heavy as other chargers and it's also a lot smaller. I love it, we'll be using it for our trip coming up!

I bought this battery last year and I can charge five iPhones or even I can charge my tablet three times it’s really good product the good thing that I got it on special price I’m planning to get two more I really recommend this for traveling in for a gift for a friend of yourself

I wanted this Tzumi-Pocket Juicer for back up power for the many power outages that happen in my rural area. It's an affordable 20,000 mAh portable charger for most USB enabled devices, and which I got for backup power for my Kindle tablet and cell phone. It's not pocket size like some other chargers, but it's still a convenient enough size to carry with you if you want. I got mine as a more powerful charger than my 5,000 mAh and for home use. It came partially charged, so I don't yet know how long a complete charge will take, but it took about 2 hours to charge it from the 50% power level. The directions do state however, that a full charge takes several hours longer. It has a set of 4 LED lights to show what level the charge is at, so you don't have to guess or just end up running out of power like other models. It's very easy and convenient to use, so I am happy with my purchase. And as always, I got it at a good price with super fast shipping from Best Buy.

This battery charger is awesome. I get 4+ charges for my phone. Be aware that this is a substantial battery both in size and weight. It is fine in a backpack but pretty big and heavy for a small crossbody bag.

+ Good capacity and multiple charging outputs + Relatively small, lightweight design + Good cost for output rating - Doesn't perform the advertised 7 or 10 charges of smart phone, getting 4-5 max - No warning when reaching battery depletion - just stops charging - Cannot charge while being charged

Great purchase, it charges very fast even though it’s a little heavy for a pocket but I’d still hilly recommend it!

OMG, this power bank is awesome. I would not trade it for anything else. Not only it last for 11X charges but you can charge up to two devices. I would tell everyone to purchase this. It's a little bulky but it does it's job. Also you can see the light that tells you how much charge you have or not. Love it!

This is one of several portable chargers I have owned. It is the first that fast charges my Samsung Galaxy Note 8. Several others have advertised this, but not delivered. Used on a family vacation to replenish several phones on a single charge (about 4 full charges) and still had juice left at the end of the day.

Recharges quickly and powers up my phone just as quick. Haven't maxed it out yet to know just how many recharges I can stretch it. But so far I've been happy with how long it has lasted before seeing lower levels. It's packed with power.

This device works as advertised. It’s capable of fast charging your smartphone and/or any device you need it to. I was able to charge a MacBook, iPad and iPhone along with a couple of other smaller items and still had juice left over.

Got this at a great price on sale and it charges my phone fast and is good when my kids tablets need juice on the go. The 20k mah is great!

This 20,000mah battery has enough juice to power the whole family on a day at the beach. I even used it to power my laptop so I could finish up some work.

Still as powerful and useful almost a year later! Fast charger

This charger works great and I don't mind spending a few bucks. Charged my Samsung Note10+ several times on one full charge. Recharging is fast.

This is the 2nd one that I bought (the first was a different brand and turned out to be a lemon), so although I haven’t used this one much, its done its job so far. I bought it to be able to charge 2 iphones simultaneously and its done that but it does take a while to charge back up. I wish the lights were bigger so I can tell how full the battery is and it is a little heavy but I knew that it would be if I wanted 20,000 mAh. The lights seem to stay on a little while even if I power it off although I dont know if it’s supposed to be like that. Other than that, it does what its supposed to and it didn’t cost and arm and a leg!

I’m in the military and I had to be in the field for days at a time with no power to charge my phone and this phone charger help me get by when it came to charging my phone and computer to finish my school work. Now it does take several hours to charge this device so I advise you to charge it over night when you sleep. But great devise to have.

A little heavy but you have to expect that for this much juice! Charges quickly and provides many charges!

Well made, max. power available for multiple charges of phones & tablets with power indicator lites and several secure attachment plug points.

Love this charger. We now have 3 of this brand and they last forever and charge quickly

It’s a little heavy but it works really well. Does a good job.
