On sale in a pack of 3 are these Xiaomi chargers which supports 30W Mi Turbo Charge and 18W Qualcomm Quick Charge 3.0. These are not USB-C PD chargers as clearly seen in the product images.
Alternatively you can use your $5 monthly eBay Plus code instead for a cheaper price.
Thanks was $16 for me.
I have a Xiaomi phone that uses these, but surely charging this hard and fast must shorten the battery life. Charging at QC3.0 rates or less would have to make the battery survive more cycles? Thoughts?
YES
I think QC can adjust the charging power of each phone i.e. 10w, 18w, 24w …
still using my nearly 3 year old redmi note 9 pro with a turbo charger. original battery and still getting good life out of it. i am using the xiaomi.eu debloated rom. my phone is slower than my wife's pixel 6 pro / and takes worst photos but me no care — battery life is king for me.
Yep, that's why on new phones they have a battery care function. I was still getting 2 full days of usage on my Mi Max 3 from 100% but most times would only top it up to 70 or 80% from 20-30%.
Only replaced it because I got a deal on Galaxy a73 5G. I miss the screen size but apart from that everything else is better.
Yeah, fast charging isn't great for battery life.
Google have adaptive charging for their latest Pixel phones where it'll slowly charge the phone overnight.
Xiaomi could implement something like adaptive charging.
I think the problem is balancing the cells. Smart chargers can do this without damaging the battery. Some lithium batteries can have a high output without damaging the cells and they can also receive high input without damaging the cells.
The battery won’t demand more than it can handle, and especially in phones heat damage is monitored and quite advanced and not just built into the battery
Except there is only one cell in a phone…no need to balance
Xiaomi's 120W HyperCharge system has "dual charge pumps" to for a "larger wattage intake" when charging the dual cells of the 11T Pro.

Then we should consider the charge and discharge rates of these batteries. If you look into RC hobbies, some motors require a high discharge rate. And batteries are made to suit…
RC batteries are usually LiPO and so are phones.
Google lipo burst rate and you can find out more. The results won’t be about mobile phone batteries exploding
I watched a video on this. It's the heat that degrades lithium cells, and they put temp sensors close to the battery and slow the charge rate once it gets too hot. Some phones can even charge at 240watt, but no doubt it's not sustained at that rate for long.
You're correct. They're not running at the max watts the whole time they're charging and typically once the battery reaches about 80% it slows down. It's really noticeable with my Motorola phone with 30W fast charge.
Are these good for turbo charging iPhone 14?
Think you need PD for that
Thanks $15.20 for me
Care to share how?
That's cheaper because it's 18W.
My phone only supports 18W, but I'm currently using an adaptor to plug it into my wall. So an AUS plug would be convenient.
Would this be fine to use with a 18W phone? It's a Mi 9T
will this work for my galaxy s9? the 30W charge
No just 18W
it steps down to whatever QC standard it supports
I thought the $5 monthly eBay Plus code could only be used for order >＝ $30 now?
Nah it shows at checkout.
oh, ok, thanks for confirming
