Hi, Plony. I got a Mustang Mach-E (first EV for us) last July and it came with a mobile charger. At the same time, I purchased a Grizz-le wall charger. We have a 240V outlet in our garage and I have only used the Ford Mobile charger up until Monday. On Monday, we got the iX. Now, I use the BMW charger because it is thicker and provides more kWh. I ask myself why did I even bother buying the aftermarket charger. If you are like most people, you will only charge at home. If you are taking the iX on a long road trip, you are going to plan ahead and find EA charging stations (especially with two free years). EA has its own charging equipment. If you are thinking about charging at your destination, then I get it. But, unless you are going on a road trip a few times a month, you can handle unplugging the charger off of the wall and putting it in your car. Unless you are an absolute imbecile or you drive 200+ miles a day, you should never be in a position that you will need to use your BMW charger somewhere other than home. The only other caveat is if you owned a second residence or something where you go a few times a month out in the country. Then, maybe you leave the mobile charger there and install a wall charger at home. I suggest you save the $400-600 and see how many times you wish you had a wall charger. Also, by then, there will be more options and some will be cheaper.
