Customer Ratings & Reviews

This charger is a great introductory charger for those who needs a continuous charge of their mobile device. I used this charger mostly on my cell phone and it works well.

I charged my phone and its still has plenty of juice. I have other banks but this is even better, almost endless supply.

TZumi has a good reputation for quality products and this backup battery doesn’t disappoint. Only thing to note is that is doesn’t come with the wall plugin charger%

This item became extremely useful when we had a power outage. My phone went dead and this item kept it charged. I rarely need to charge it and this is a BONUS.

This charger is a little heavy in my purse but an absolute life saver. Holds the charge for a long time even charging several phones at one time. LOVE IT!

Needed a high power external battery for my phone and this one does the job. I am never without a charge no matter where I go.

I love this portable charger. It charges itself fast and it also has a fast charging port that actually works as fast as it’s suppose to. I couldn’t be happier.

Its a great charging pack definitely holds a long charge! But it is super heavy so if you're carrying it on your body expect to have less room in your pockets or bag and for it to be weighed down a lot.

Wanted to have something to power my portable devices in case of power outages during this hurricane season. This one has plent of juice to spare.

This item kept both of my families phones charged on our 5 hr flight to Florida. Great item!!!

We love this! Everyone has one in the house and comes in handy sooo many times! Holds juice for the whole hr trips we need them to!!

Had to travel a long distance without access to power. This power pack kept my devices running related to the specifications it claims.

Needed some extra juice on the go and this comes in handy when my phone or other devices need power.

The LED indicator is great because it let’s you know how much juice it has. It also has a nice look and it matches my iphone.

This is a great product to keep your phone charged while out and about. Fast charges.

Can easily charge my S8 6-8 times before needing to recharge the portable charger.

External power sources are usually giveaways at trade shows or as SWAG for various functions. This one works well and fast.

Great price for a quality product!!!...It charges my phone very fast, and several times before needing plugged back in.

I used it during my stay in Japan, My cell phone would charge really fast and never died due to this device's supercharge

Requires USB to Lightning cable for iPhone. High capacity and percentage power remaining are both useful features.
