Customer Ratings & Reviews

The best iPhone portable charger I've used. Great for road trips as it can charge your phone several times. Although a little bit bigger, but it is worth it.

Bought this so I could charge my phone while traveling overseas. Provides enough charge to last me all day. I use my phone for GPS and surfing the internet while I'm on the train. Only issue is recharging the pack seems to take all day - or at least that's what the charge indicator says.

This external battery is great.it looks sleek and is compact but offers great charging capacity and has 2 USB ports to charge 2 devices at once.

I love this charger. It has sat in my computer bag for a couple of weeks and it barely lost any power. I have used it to charge a device 3 times before the charger was down to 1 bar and needed charging. It has indicator bars to let you know how much power is left on the charger. It also seems to charge my devices a lot faster than my fast charging adaptor for the phone/tablets, about an hour or so. Only downer is that it takes a long, long time to recharge the charger if it's real low, several hours.

More economical than the other chargers. Easy to use out of the package. Powers up 2 cell phones quickly. Very happy with this quick purchase.

Charges my IPhone 6 fast and between 6 or 7 times before needing a charge. Can charge 2 phones at once . Very pleased with this purchase.

This was great during Hurricane Irma that I bought one as a gift! Make sure it is fully charged prior to a hurricane or when you are ready to store it again and it is there for you when you need to charge your cell phone.

The charger provides a strong charge to charge your device quickly. It is a decent price point compared to other products. It is a bit heavy and takes a little bit of time to recharge.

Perfect portable charger for travel. Holds a charge well, charges devices quickly. Doesn't heat up like other portable chargers.

I bought this item JUST in case I was not near a power outlet and it was very useful. On one charge it kept powering up my phone for several days. Mind you, it was never used to charge my phone to 100%, but I never ran out of juice on my portable charger for 3 days. It also charged quite quickly. It does have 2 ports to charge 2 electronic devices. Tzumi was slightly thicker than I expected, but doesn't feel too big to carry around in a purse. I am very happy with this purchase. Affordable.

Charges my devices fast! Lasts for days before having to recharge the battery pack itself. Mobile and sturdy.

Holds a pretty good charge, outer casing is silicon like (meaning it won’t slip on surfaces easily), and after owning this for a year or so I can confidentially say that it’ll keep working as expected after a few drops. I now own 3 portable chargers and I’d sum this one up as being a happy medium of all the things you’d want in a portable charger. It isn’t to heavy or bulky and it’ll charge your device a few times over before needing a recharge.

Take my cable everywhere i go, and i just love it. Comes with a strap that ties your chord so its more compact. At first i thought of taking it off but after a while using it it became really handy

Bought this a few days ago, comes fully charged and charges my iPhone 7 very quickly. Not the smallest portable charger I’ve owned, but it certainly does the job well. Handy that it has two ports.

Great battery. Holds a lot of power in a fairly small device. And charges devices quickly too. Would recommend to others

Easy to use, compact and carries a sufficient amount of backup juice.

I love that you can charge two devices at once! My family is always trying to use my extra battery when I take it out because I need it. This device recharged my phone and iPad and by that time usually 2-3 other people’s phones before it looses charge. I charge it over night once I’m home so I don’t know how long it takes to charge itself but by morning, it’s ready for the next day.

Looking for a way to keep your devices charged when you need them the most? Look no further, you have found it. This charger works very well. Will give you 2.5 charges for your new iPhone X.

This battery is awesome. It does rapid charging, can fully charge my phone 3 times and is 1/3 the cost of a morphie.

This battery is a bit bulky and heavy. It does a great job of retaining its own charge. It is superb at charging a cell phone and an I pad very rapidly
