I have 2 phones:
- My iPhone XS (added in a metal ring so it sticks to magsafe chargers)
- My wife's iPhone 12 Mini w/ official Apple MagSafe case

I bought the ESR HaloLock magnetic car charger (x2, one for each of us) and I bought 2 chargers that support QC 3.0 / 18W charging. ESR says that it will charge at 7.5W if you plug in a 18W QC 3.0 compatible charger to it.

I turned off my phone screen and attached it to the charger. 20 minutes later my phone was sitting at the same percentage.

My understanding is that the XS and iPhone 12 Mini both support the same wireless charging speeds, except the 12 Mini has MagSafe in addition.

Why am I not able to charge effectively on this ESR HaloLock car mount? It does not say it is MagSafe specific. My wife's phone wasn't charging quickly either.

You need a 18W power adapter for it to fast charge. Also it claims to adjust the charging speed based on the heat generated by charging. So if the phone gets hot the charging speed will be lower.

Heat is an issue with MagSafe chargers including the one from Apple. I would say use it as a holder rather than fast charger.

That's frustrating for sure. I am returning the ESR one and buying one with better reviews for iPhones. ESR has good Android reviews but mixed iPhone reviews. There's one called "Waitee" that I am going to try. These are all cheap Chinese garbage. I wish Belkin or another reputable company like Ankur would make a good one that has charging built in.

The ESR claims 7.5W charging but Waitee says it can do more. We'll see when it arrives on Saturday.

PS - The AC is on the vent so the phone is cool and so is the charger. And I was using a QC 3.0 charger which is 18W. 🙁 The QC 3.0 charger was DEFINITELY not pulling hardly any wattage at all. When I plugged my phone directly into the QC 3.0 charger it charged fast, and the QC 3.0 charger got warm, but not through the ESR wireless charger.
