iClever sent me over a 10 watt wireless charger to review recently and after about a month of playing with it here’s my take.
Like all wireless chargers, it’s dependent on the power source to back it. It’s a coil, a chip, and a cable. This particular coil is not the strongest I’ve had in that I can’t get fast charging with my case on, but I believe that charger that did that was living fast and loose with the specs.
That charger also ended up heating the phone to 120F+ and getting thrown away, so take that with a grain of salt.
I don’t have a lot to say about the iClever charger other than that they’re evidently advertising it at a lower wattage due to iPhones only supporting up to 7.5 Watts. That being a large chunk of their audience they’ll undersell what they can do to have the right number advertised to half the population.
Coming in at under $12 for a 10 watt charger, it’s got the most watts supported per buck, although you will have to provide it with something to power those watts.
