Customer Ratings & Reviews

Works very well for a source of power for ac plug-in and electronics charge (cell phone, tablet, etc.). Foreign (outside the U.S.) electric sources not tested.

Was in the mall, and needed something to charge my phone in a hurry. After talking to a bestbuy associate, bought it. It's the Best portable charger. Very reliable.

This charger holds a charge for a very long time- however the single on/off switch feature makes it confusing on whether or not it is on or off.

The charger is a great addition to any day pack. It holds a significant charge to ensure that all items were recharged and ready to go.

Had trouble trying to charge it. Used different plugs still no charge. Was almost ready to return it when i tried my IPad plug and it charged.

I bought 2 of these for two of my granddaughters and they LOVE them! They take them on trips when they travel and use them when they are hunting Pokémon.

I carry this with me at all times. I love that I can charge 2 devices at a time. Very helpful during tournaments when other parents need to charge up

This is my second purchase. The first one was for me and this one is for my son. It worked great through the storm and while traveling. Lots of juice!

I love this item I had misplaced one that I had and got myself a new one. Don't know how much you use it til you get a new one

Took this product for use in another country and let's just say Rest in Peace even after using a converter.

Great pickup for my recent cross country flight. Kept my iPhone and iPad juiced up. Must’ve recharged at least 5 times.

He likes it. I like the fact that he has a charging source while using the GPS on his phone while out on long bike rides.

Very pleased with Tzumi products we have purchased. They are a great quality and reasonably priced! Will only buy these Portable Chargers!

Purchased this for my daughter's school ipad. Honestly, I haven't used it yet, but I'm not expecting any issues. If I do, I'll report back.

This product is wonderful. It helps me charge all of my wireless products especially since I have an active busy lifestyle.

I bought 2 of these for an upcoming trip. I’m currently using them while running around town. Great priduct works well.

I think this is a great product but I should’ve spent a few more dollars and gotten one that was a little bit more powerful.

Wouldn't recommend it. Only gave one charge when we were told it would charge at lease 3 or 4 times. Thinking about returning it. Well look at the return policy.

So handy to have on an airplane so I can watch a movie and not worry that my phone battery dies in the middle.

Did exactly what is was supposed to, easy to use and understand, and came in handy while I was on a trip to CDMX.
