Frequent Questions

  • Will the base case work with a mophie charge force mount?
    Yes, the magnets in your base case will firmly attach it to mophie charge force mounts, so you can conveniently dock your phone while you’re driving or working. However, your phone will not wirelessly charge from the charge force vent mount or charge force desk mount.
    Does the base case case work with other magnetic systems?
    We do not recommend using the base case with 3rd-party magnetic systems. The magnets in the base case will firmly attach it to mophie hold force accessories and to mophie charge force mounts, but we cannot guarantee that they will adequately hold when used with a 3rd-party magnetic system.
    Will the base case work with my iPhone 6/iPhone 6 Plus?
    The base case was designed to work with the iPhone 7/iPhone 7 Plus. Although the iPhone 6/iPhone 6 Plus will fit in the base case, the base case camera cone does not align properly with the cameras in those older phones, which may impair your photos. Because of this, we do not recommend using the base case with the iPhone 6/iPhone 6 Plus.
    Do the hold force folio and hold force wallet work together?
    You bet! You can attach the hold force folio to the base case and then attach the hold force wallet on top of that, giving you even more flexibility!
  • Can I use the hold force powerstation plus mini battery and hold force wallet together?
    The hold force powerstation plus mini battery only has magnets on the side that attaches to the base case. You can’t attach other hold force accessories on top of it while it’s attached to the base case.
    Does the base case work on a phone with a screen shield?
    We’ve made sure that the base case will work with phones that have a ZAGG Invisible Shield screen protector installed. We cannot guarantee a proper fit with phones that have other brands of screen protectors.
    Will this product demagnetize my credit card?
    Absolutely not! It’s perfectly safe to carry your ID and credit cards in the hold force wallet and hold force folio without harming their magnetic information.

base case is rated 3.9 out of 5 by 14.
Rated 3 out of 5 by from Only lasted 4 months I bought this 5 months ago and it was great. But I woke up extremely late for work because my phone was never charging when I plugged it in the case charged but my phone didn’t I tried everything and nothing works.

Rated 3 out of 5 by from great concept but pool quality and heavy the concept are very good but the gap between case surrounding and the back are not smoth, some cut off port are not smoth. also the case is heavy. heavy means easy to damage the screen when drop off. But it works, you can leave your wallet away and put your 2 card into the wallet case at the bcak of the base case. just very heavy.

Rated 3 out of 5 by from Good but scratches very easily. The case works well but the plastic back scratches so easily. Right after opening it and putting it on my phone it scratched IMMEDIATELY. You cant even lay the case back down on a table without getting scratches. I've had it for about a week or so and it looks as if I've had it for months or as if I rubbed the back against concrete. Looks like i'll have to buy a new one every month or so

Rated 2 out of 5 by from Not that great I was expecting a magnetized casing but it's just two thin and somewhat weak magnets that sit inside the case - not worth the money. I could of bought stronger magnets and glued them on my old case
Date published: 2017-06-26
Rated 2 out of 5 by from Great Concept, case is the weak point I've had this system for a week now and it's ok. I like the idea and using the battery and wallet are convenient. My biggest complaints would be the strength of the magnets to hold on the battery, and the quality of the case. After only one week, the back of the case has a lot so scratches that really show. If I could do it again, I would go with the system that uses wireless charging bc of the leather case. If they had a leather case for this system, it would surely hold up better. The only thing that I like about this case is that the bottom is completely exposed, which allows for docking.

Rated 2 out of 5 by from Disappointing I bought the hold force case in the hopes the magnets were going to be strong enough to hold the phone on metal surfaces. Much to my disappointment this is not the case. The case also scratches extremely easy and seems to have poor manufacturing when it comes to the edges of the plastic portions. Wouldn't suggest this case unfortunately, but still recommend Mophie for other products in their array of lineups.
