Great battery to charge cells and tablets on the go.

I like it as it can charger my laptop but too heavy to carry around

Good charger at a great price. A lean modern slick look, easy to see green power button, not too heavy not too lite.

Holds enough to recharge my cell phone seven times.

Has a lot of battery capacity, very fast to charge.

I bought this to power my Apple Watch and phone through 3 days at Sasquatch. It did not fail! Very happen with the amount of recharges I was able to get and it only drained the battery down to half. Should note- others also used it to charge their devices. This was cheaper at another retailer but Best Buy price-matched.

Great Capacity, great price can't go wrong here...

The device is great, operates as it should. My only concern is that it takes a while to charge (obviously, they tell you that and it's expected of a 20k maah battery) but it looses its charge quicker than I believe is advertised. Granted, I am not expert but this is just based on my observation. Definitely was still worth it as I got it on sale for about $23.

I learned a few things from Hurricane Harvey and decided to buy 2 of these! I had a smaller version when Harvey hit and it was a lifesaver since we had no power for 5 days so purchasing 2 bigger ones was a no brainer. Just get one... "Better to have it and not need it than to need it and not have it!"

Tzumi - PocketJuice 20,000 mAh Portable Charger is a great option to keep my phone powered up on the golf course or when I am using my phone as a hot spot for my work laptop. It charges quickly and this model can charge my phone 10x+. I bought these for all my family members. Great item at a great Best Buy price!

Holds a lot of juice for multiple charges, charges quickly

It finally ran its course. It has been my go to staple for over 2 years. I’ve charge 4 cell phones from 0 to 100% and still had juice left to charge more. It finally died. A bit heavy.

It charged my cellphone quick,it is a little heavy in my purse

Used it for a few weeks to power up a Remote IP Camera. Able to keep the IP Camera running for more than 26 Hours in one charge. So far this Power Bank was able to recharge itself back to full power quite nicely. So far so good. I am quite happy with it. I plan to buy a 2nd one for my next travel trip.

Saved my family's butt on our vacation to Disney. One full charge (which takes FOREVER to achieve) charged a LG G6, a Galaxy S8, and an iPhone 8 almost twice. A little bulky but not overly heavy. I also use it at work on my bus - it beats the wonky cigarette adapters when I'm on long trips.

This power pack gets hot when, charging, charges slowly, and sucks a lot of power in the process - if for example you're using a solar panel, forget about it. With that said, it's a beast of a battery so I recommend it for domestic travel and trips less than a week in length

The unit is good, but the charging cable sucks! This allowed us to keep multiple devices charged every time we go on vacation. Worth the money....that's "if" you can get it to charge. Buy another cable for sure!

I've had my power pack for a few months now and have used it a few times. It really holds it's charge, and I have recharged my entire iPhone 7 Plus and still had enough for probably 5 more full charges... It's sleek and slender and not heavy in my opinion. I carry it in my attache. I would buy again.

This charger works great and is even more convenient for the entire family who is always on the go!

Tested this out while on vacation for 4 days. Played music with my phone on 2 Bluetooth speaks the entire time and was able to charge all my devices multiple times on a single charge of the PocketJuice. I like the size also, not overly bulky or heavy. I'm really happy with this product so far.
