Yes, almost any case can be used with the PowerBase, as long as it is not extremely thick such as credit card wallet phone cases, cases with a magnetic plate or pop sockets.
For the best experience, we suggest to use our SnapMag cases as the case has a built in magnetic ring that will align with the magnets inside the PowerBase, giving you a precise connection every time. MagSafe compatible phone cases will also allow for magnetic alignment and connection too.
