Customer Ratings & Reviews

Heavy duty heavy weight is precisely what this product is. I've used it simultaneously charging my mobil and tablet and later enough to give my Sony camera a "top up" Having said this, this is heavy in weight so best have a place that can comfortably accommodate the unit. It typically resides in my camera bag or backpack specially for those times when you're no where near an out let.

Long run battery charger, just a bit heavy if you want to take it on travel.

I charge my iPhone straight 6 days almost a week :))(from ~30-100% after work). I'm happy with this power bank since I don't have to worry it runs out power l. Also when charging I can leave overnight because of 9hr charging to full, I don't have to worry when to come back to take it out from charger. This my best power bank I have.

It's on the bulky and heavy side but charged our phones very quickly several times.

Last very long. Even charges my tablet within a hour.

Holds and gives many full charges but heavier than any other that I've owned.

Great portable charger that last a long time and can charger multiple devices.

Great charger for the price, charges fast and is durable.

This was a Christmas gift for my husband and 2 grown sons. They are all on the road a lot and we're very excite to get this

20000 MAH for under twenty dollars, can't beat that!

does the job. easy to use. charges fast. would buy again.

Fast charge. Like that you can charge two things at once.

Great product I travel a lot for work and spend quite a bit of time in airports and it is impossible to find a space at the free charging stations it comes in handy. When you loose power and phone needs charging like it happened to me it came in handy once again. Long lasting holds a large charge

I purchased this battery pack when it was deal of the day, and I used it a few times, the battery pack is not bulky and I got about 3 full charges for my 2 phones - Samsung Note 8 and S8+. Note, I used the battery pack to charge from almost 0% to 100%. I wish I can get more, I will keep monitoring.

I bought the Tzumi - PocketJuice 20,000 it is really good. I go through my battery a lot through out the day and this pocket juice last me all day and i still have enough juice to charge my phone the following day without having to recharge it. Over all I am satisfied with this product i have had others in the past but they never seem to work as well as this one.

I got this battery backup for the big capacity - 11 iPhone charges. We use it regularly (it will charge 2 phones at once) and it has never run down. I was concerned it might take a long time to charge all that capacity, but it charges overnight. Although it doesn't plug directly into 110v (need to use USB) that has not been a big problem.

Charges quickly. Powerful but a little heavy and bulky.

I had been looking for a good portable charger for my phone when camping. This does the trick in a fairly small package and does a great job charging quickly the devices you want charged. The only issue is charging the actual battery is slower than I'd like it to be. It is a small issue though. It easily kept my phone and watch charged for a 4 day trip with no issues.

bought two of these to take on a back country camping trip in Yosemite. We had 6 phones and 2 cameras that we needed to charge. We stayed for 7 days and we never had to worry about not having a phone, kept everything charged and ready! would highly recommend to anyone looking for a portable handheld charger.

I bought this charger for my grandson because he was going to a concert. He hooked it to his phone and took pictures and video taped the whole concert without any problem and still had about a quarter of the battery left. He came home and was very happy that the charger was able to hold up for the whole thing.
