Customer Ratings & Reviews

So the whole Universe product line really interest me so I bought all of the products that I thought I would use and would be nice. Some of the products work really well and other do not. Here is a lit of products for the Universe line that are awesome: USB Flash Drive Extended Storage Extended Battery Wallet Here is a list of products that I do not feel work as well as they should: Armband Vent Mount Kit

This provides additional power when you need it. Works well and was easy to install.

Easy to use. Slides on the case and provides a quick charge. Nice product.

I bought this as a Christmas gift for my best friend because i have one for myself. The gift of portable charging is priceless especially if you're caught without a charger. If you do not touch your phone while it is charging it will reach about 80% with this being fully charged. If i use it while shopping (normally at target following specials) it will reach around 40-50%.

I have several power devices. This is easy enough to carry and use when I need it, but it is also slim enough that I can attach it to my phone and still have the ability to move around without bulk, weight, and cords attached! The easy attachment to the Otterbox case is slick. I just pull the charger from my briefcase or messenger bag, and I am ready to go!

I bought this anticipating being able to use the add ons when I got my iPhone X. However Otterbox isn't going to be releasing a Universe case for the iPhone X. If they aren't going to keep the line going, it really isn't worth buying into it.

I have a usage scenario in which my iPhone is heavily used for an eight hour shift, and yet can't be allowed to run out of battery charge. The peace of mind associated with having a ready-to-swap spare battery is well worth the price of admission alone. Plus it's from Otterbox, so what's not to like? Very satisfied.

Originally $50, great power supply for the Otterbox case.

Great external power pack for this Otterbox case!!

Have had the uniVERSE system for a few weeks. Ow and while this battery doesn't have a ton of capacity it certainly provides a 100% charge when I need it.

This is a great case. The only reason I gave 4 stars instead of 5 is bc I wish it had a face on it. But other then that this is a great product!

Interesting concept. I like the ability to remove the battery. I can keep my phone case slim but when I need more battery I can add onto it and it will usually get me about an 80% charge.

I would definitely recommend this item to anyone who travels as much as I do. I love it. I love the brand! I love this brand as much as I love Mophie (and that's saying a lot).

The battery is a little bulky and can be difficult to disengage from phone when attached to case. Otherwise has Otterbox dependability

Love this whole otterbox system. Have the speaker phone protector and backup battery. Getting the flash drive for Christmas. Everything you need and it's otterbox!

Wish the battery would charge the phone to 100% however it is a great boost to get you thru the day!

I love this collection from Otterbox. I just slide off a section on the back of my case and slide this charger in. It is so easy and convenient.

This attachment for the iPhone in a otterbox universe case is a great way to extend your iPhone's battery life if you are not around your charger.

Great phone case. I enjoy the ability to add the battery pack when it needs to be charged instead of having to use a different charging cable

This is a perfect fit for the otter box universe case for the iPhone 7 plus. Charges easily and really helps when you need extra battery power.
