Customer Ratings & Reviews

I used this for an international trip. It charged my phone and watch several times during the trip without recharging it. I was very happy with it capabilities and how it satisfied my needs

Great power pack! Multiple charges to devices before needing to charge the pack itself ! Would definitely recommend this to everyone who reads this !

worked well, charged two devices at one time. the case is rubberized and has a good grip, and survived a fall. the trip was to a city, so not so much rough treatment.

I’ve been pretty happy with this pack. I get at least two phone charges out of each pack charge which is so much more convenient than having to plug it in at a wall. So far so good.

Great portable charger. At least 3-4 charges if your phone is totally dead which most of the time it is not. I would recommend to purchase if your in the market for a portable charger.

It does what it is supposed to do. I bought 2 of these. I have not had to use it for an emergency charge which is why I bought it. I tested it and it worked.

This portable charger is great. I have had other chargers but this one allows for multiple charges and lasts a long time. It’s a little big and a little pricey but well worth it.

Awesome product, especially when traveling or riding out a winter power loss. Also during summer storms when power could be out for days.

This Tzumi packs a lot of power for its size. It's about the size of my phone only a little thicker. Fits right in your pocket. Charges well even when using what your charging.

I really like this pocket juice power bank it charges my phone and smart watch fast and it doesn't take that long for tha charger it self to charge too love it!

Love this thing I take it everywhere. As a Pokémon go player I find it very useful. Also useful at home so I don’t need to stand near an outlet.

Bought the product to take with me to a concert and it worked great, ive had it for awhile and it still charges fast

Kept my phone and rechargeable flashlight powered during a recent power outage. Fortunately it was nearly fully charged when purchased so that it saved me from losing phone service on my mobile.

I use my iPad to write hail damage estimates on vehicles and this power bank kept it charged on very long (12hr) days in 100 degree Texas heat. Highly recommend.

Great product! I have several of these. We use them on trips and sporting events when keeping up with the scores. They last for a while!

Long lasting and my primary hiking portable charger. Long battery life and hadn’t given me any issues so far!

These are great, they last forever , awesome gifts , everyone needs one of these , never be stranded with a low battery or a dead battery

A life saver that everyone needs Nice present that anyone can use on the go A essential requirement for any mobile electronic device

Purchased it for international travel but it has come in handy for camping trips and extended periods of time without connectivity

This will charge your completely dead phone to close to 100% in an hour. This is my second Tzumi charger, very satisfied with first one.
