MacRumors Giveaway: Win an iPhone 17 Pro and 25W Qi Charger From Lululook

Temu & AliExpress sell something similar for ~$20~30, with some different colors.

In testing, only 25w MagSafe or Qi 2.2 chargers with active cooling are actually able to appreciably charge anywhere near 25w due to thermal constraints. 25w chargers without active cooling are only marginally faster than 15w ones, and are not able to hit that 0-50% in 30 mins metric in real world use.

I tested the Ku Xui Qi 2.2 version of this against the ESR folding Qi 2.2 (the latter of which includes a quiet little fan). After a week of testing from around 10% to 80% on both chargers, I found the fan didn't make much difference in actual charging speed (10-50% was about 25 minutes on either charger, and 80% was always about an hour). My phone ran about 3-5 degrees cooler on the ESR with its fan on, but only when I wasn't using a case. As soon as I had my phone in an Apple Silicone case, the fan made no difference to phone temperature (no surprise, really).

Also, the Watch charger on both units charged my Series 10 up just as quickly as the official "high speed" Apple Watch charger, so long as the watch screen stays off. As soon as you touch the watch, throughput drops while the screen is illuminated.

I think passive cooling with an aluminum charging unit works almost as well as the active cooling on a plastic unit. Now if that was combined with a heat-dissipating phone case, maybe we'd really have something.

By the way, I consistently measured the charging via Qi 2.2 at 80% as efficient at charging directly via USB-C (which also heated the phone up nearly as warm, but was around 20% faster in the end). I didn't expect inductive charging to be that close to wired, based on previous measurements with the older non-magnetic alignment systems.
