You are. Provide a lot of amps. Each device will take just as much as it needs. So err on the side of more watts - it will even help your batteries charge faster.
The only thing that can be diminished with fast charging is the number of battery cycles (the battery lifetime) so set a low charging engage (only charge if <= 50%) and a high ceiling (stop charge if >90%) in your bios: this will increase your battery life.
Source: all my devices use USB-C. They all share the same AC adapter with power delivery, and a Lenovo Dock also USB-C with PD.
No USB-C charging = I don't buy.
- ahartmetz 6y agoThe rule to maximize life of Li-Ion batteries is to keep them between 20% and 80%. Total charge and discharge current cause wear, especially in extreme states of charge. The number of cycles only matters when you assume a given amount of charge in each cycle. The batteries of my 7 years old previous laptop, which was used mostly stationarily and mostly kept at 75-80% state of charge, are still at above 90% capacity. I don't fully trust the >90% reported, but the batteries are quite obviously still good.
- atonse 6y agoI got excited at the idea that I could set those thresholds on my MacBook (like on a Tesla) but then realized when you said BIOS that you’re talking about a PC.
