My analogy is an EV - of course your EV isn't going to pull current that's dangerous but fast charging it has been shown to degrade battery life - especially if the EV doesn't have active cooling for the battery pack.
Putting that EV on a slow charge that might be sufficient for an overnight charge might be better for the battery pack.
- hackmiester 3y agoYou are correct, but the comment didn't say "fast chargers," it said GaN. Here is a (very cute) 35W GaN charger. This would be considered fast charging for a phone, but not for a laptop. https://sharge.com/products/shargeek-retro-35-gan-charger https://sharge.com/products/shargeek-retro-35-gan-charger It is just plain inaccurate to state that GaN is the problem, or opens up new possibilities for fast charging. All it does is make the charger smaller.
- creativeSlumber 3y agoThis is a setting on the device side. The EV it self will decide how much current to pull, based on charging profile that you set. You are correct on that charging at higher currents can reduce battery cycle life, but it's the device it self that decides how much current to pull based on the charging profile that you selected. In your example with an EV,you set the charging profile on your vehicle, not the outside charger. The charger's job is to provide as much current/voltage as requested by the device.
