Customer Ratings & Reviews

In my opinion, this doesn't feel heavy or bulky. Charges quickly. Feels good in my hand. In my experience, it gives me one full charge.

Let's you wirelessly charge your phone, slips into the universe case snug. Does require a micro USB cable to charge but it will also charge your phone when it is plugged in.

I would recommend this item to customer to use this product very helpful not to bring my cable charger anymore and buy this mophie charger and case together.

Excellent battery add on. Slim. Love the wireless charging aspect.

Very simple and easy way to charge your phone. I purchased this right before a seminar and am glad I did. I’m usually the person in my group of peers that brings the backup battery pack for our devices. The fact that I was able to slide this in and charge my phone was excellent. It appears to drain rather easily, however, that could be due to continuous use of the phone while the pack is engaged/active.

Great battery backup. Keeps my phone charged al day long.

It’s nice to have a battery pack that connects to the phone case so you don’t have to carry extra cords or have something hanging from the phone to charge it.

I really have nothing negative to say about this external reserve battery attachment for the Otterbox Universe case. It slides on nicely with the case and it does what it is designed to do. It will give your phone about a 40% boost. It is great for those really long days that you haven't gotten a chance to charge your phone and just need a little more juice to make it through the day.

It is very heavy but give battery life a huge boost.

This case offers different accessories. My faves being the power pack & magnetic bases. So much easier to find on my desk and it doesn’t fall off in the car. Best yet that my battery backup is there and ready to go

I am happy with the universe system. I keep this in my handbag. Doesn't take up much space. It provides one full charge for my iPhone 7.

Good backup/second battery but it is attached and while attached you cannot use your lightening cord to charge so that is a hassle to have another cord.

Could be a little sturdier for the add ons but comes in handy

Charged my phone from 20% to 50% witching like 20 mins

I like the fact that I can add some Juice to my phone in a pinch but the added bump doesn't even fully charge my phone. I'd say I get about a half charge out of it. Admittedly I have have been expecting too much but regardless the extra Juice does certainly help on long days.

Great product for the OtterBox Universe line. Only complaint is the battery needs to be a bit bigger. Enough to charge a full charge

A must for ones to one the otterbox universe case.

Great product and affordable too. I am glad they came out with this product

Best item ever I don’t need a charger cable to plug in

Overall good addition to the otterbox universe module case.
