Customer Ratings & Reviews

Went to Coachella this weekend, it lasted the whole week with multiple people using it on a Apple fast change cport. I was shocked it still had 25% left after over 10 people using it. It charged my phone from 0-100 in around 45min with the Apple fast charge cport cord. Along with my iWatch. Expensive but defiantly get your money’s worth.

I use this while at school with my iPad Pro 12.9 and MacBook Pro. I love the fact that you can charge pretty much whatever device you could own because of the inclusion of USB-C. When charging my iPad by itself, I couldn’t get it to drain faster than I could charge which is what I was looking for in a backup battery (even when charging the iPad and iPhone at the same time.) From the QC 3.0 port, its as fast if not faster than a 12w USB plug in adapter (which has no problem keeping up with the iPad Pro 12.9). When it comes to the MacBook, it WILL charge, but NOT fast enough for heavy use (this charger doesn’t inlcude USB-PD). The only thing I don’t like is the exclusion of USB-PD and it feels on the cheaper side. The casing flexes pretty easily.

This portable battery is ideal if you carry both a iPhone and iPad with you for school or business purposes. It can charge both more than twice, and not too heavy of a product if you have a backpack or messenger bag with you.

Charger is very good. Charges both of my iPhones at the same time, and has juice left over. Very large compared to other batteries I’ve used.

We bought two of these and they charge items quickly and can charge multiple items at a time. Nice purchase!!

This just hyper charger just plain works and it’s a must have if you need that extra charge for on the go. Stay charged up no matter where you go with this Tzumi HyperCharge power bank. It does Offer up to 10 times charging for smartphones and 2 times charging for tablets, and 1x for the new MacBook Pro this 20000mAh portable station is what you need period

It takes a while to get it fully charged however this thing lasts a very long time if you're using it for mobile devices. I was also able to keep my MacBook Pro from completely draining while editing some video on a flight recently. I typically attach this to my cameras while recording longer video segments.

Bought this to replace an old Insignia battery pack. Has fast charge and can charge multiple devices several times over. Only drawback is the cables that come with it are only about 4 inches long, but cables are cheap and easy to come by.

This is the BEST charger - carries well in my purse or backpack, and chargers my phone 3-4 times on a full battery. I love it!

I bought this for my daughter, and it definitley helped keep her phone charged as it stores a lot of battery!

very good... last long hours.... like 99.99% charge last longer and very useful on the road to go anywhere

This charge my galaxy S9 super fast. Because provide Qualcomm 3.0

Great Product . Charge up really quick . Very durable and handy.

I went for the larger mAh for longer life and more charges hope it works

I am still charging it for the first time so I can't give an accurate rating but it seems well built and I'm happy so far.

It’s pretty heavy . Kind hard to carry around being very heavy . This charger doesn’t hold charge for too long and the big downfall is it’s just too heavy !

Just got mine today and it charges iphone 6-7 and android Motorola Z Force. I am able to charge the HyperCharge 20,000 with both my android charger and my wife's iphone charger. 4 stars because I can't charge a device while the Tzumi - HyperCharge is being charged.
