Customer Ratings & Reviews

You have no idea how many power banks or portable batteries I have bought. This one by far takes the crown. This was one of the first ones I ever bought. I have dropped it, abused, thrown it and what not and it is still working. It's incredible how much abuse has this battery has had. I just can't find another one like this one. It lasted an amazing amount of hours even if I was charging different things at the same time. It's just amazing. So sad they discontinued it.

Super fast type c charger as well as normal 2.4A. 20000mA battery that charges the phone plenty of time. The only thing with it that it is so big the length is exactly as my Sony xz premium and the width is little narrower and the thickness is around 1.5"

I use this charger to power my iPad, iPhone X, AirPods, and even my Apple Watch when I’m traveling and my cord and brick are in my checked luggage under a plane somewhere. This has gotten me through 15 hour flights with juice to spare. Great product, plus you can charge on USB-C.

I was actually at a mobile Best Buy store located inside the Tanforan mall looking for some new apple earphones. My boyfriend and I was talking to an employee whom was super helpful! We saw these at the store and it says that this bad boy can fully charge your phone 11x!! That’s way more than enough for a normal day, but I need something that’s going to last me for EDC so this is perfect! Plus checkout all the cool ports that it has as well! I highly recommend it. I wish it came in a rose gold color, like my old mophie one, but that’s no big issue. I also wish it was a little less bulky. It’s quite the fingerprint magnet as well die to the material it is made from. Another great thing is that it actually has a digital screen showing you the battery percentage left on the portable charger. How cool is that?! Plus it even comes pre-charged!

This charger was priced right and provides several charges for everyone's phone in the family when we are away from outlets.

This is a little heavy due to it's size. But it is a powerhouse of a charger so I don't mind that at all. You can use it several times to charge your phone and it does recharge itself pretty quickly. I'm glad I bought this one.

I bought this for my mother, who has to use her phone all day on the go as part of her job. This has been perfect for keeping her phone charged all day and has yet to be recharged since using it on Christmas (now 5 days later).

Charged my iPhone 5 from 0 to 85% in 1 hour and battery still showed 100%. Took 1 more hr to go from 85% to 97% a ratio which matches what I get charging iPhone direct from outlet...my iPhone battery is old and this is normal. Have yet to try how fast it charges for 2nd, 3rd, 4th, 5th, etc charges as well as how fast it goes down from 100%. it says it can charge up to 11 times...twice as much as I'll ever need but always good to have a reserve and not push it's limits.

Bought this to replace a lost portable charger. I was afraid I would not find something as good as my original. This one was bigger than my old one or than I wanted but went with the good ratings. Has not let me down. The size is manageable and can repeatedly charge my phones and tablet. Much more power that I expected, love the charger display, great to know exactly where you stand. If I need another in the future this will be it.

I have charged phone multiple times and Bluetooth headphones about 8 times. The Tzumi is still at 89%. Love this product.

Great charger for my phone. Charged as well as wall charger for phone.

Charges super fast and lasts forever. Only 4 stars cause it’s big and bulky. But I’m ok with that cause I always have a charge

I have had this power pack for a while I can go for over a week on one charge it is that amazing. It’s a little bulky but to only have to charge once a week to run my phone and my Bluetooth speaker for 12+ hours a day six days a week to only have to charge once a week or so is awesome. Would highly recommend this to anyone!

I purchased this last year and I keep it in my purse. Definitely a must have, can charge up to four devices at the same time. Usually lasts about a week if I charge my phone or headphones more than 8 times for a full charge. It is heavier and about 6-7 inches long, so keep in mind if you want to carry in a small bag.

Got this on sale for $45. Loved it so much bought two more. Charge your smartphone from completely dead 7-10 times with this thing on a single charge. Charge the entire portable battery pack uonfrom empty in only 4-5 hours using included USB 3.0 cable (comes with a super tiny one) and your own wall adapter.

Great to have the Pocket juice to charge the iPhone whenever the battery dies

Used it for the first time this weekend I was in Northern California. Not only did I not need to use a wall charger once. I came back with 40% of the charge on the power pack. My phone was plugged into the power pack often and the power pack was never recharged. Super stoked on the purchase.

The 30k capacity of this bank is amazing, I don't think it's ever fallen below 50% before I am able to charge it again. The price totally justifies the capabilities of this monster, and I would definitely buy it again if they came out with a 45k or 50k variant

Like others stated in their reviews, it can take a day or two to fully charge once depleted, but it can last a long time afterwards. I made this purchase for a school ski trip (chartered bus) and it worked great for the kids (they shared). I like the cable / port flexibility too.

Bought this battery pack for a festival. Charged quickly and had almost 10 charges on it
