Question about Laptop Charging Circuit
Question about Laptop Charging Circuit
I recently purchased a used Inspiron 14 5425 with a regular 65w charger, which is quite a step down from my RTX3070 MSI GF66 Katana that requires a 245w charger. This situation made me curious about the maximum power the Inspiron can handle and whether I should stick with the higher wattage device. However, I haven’t found clear guidance on this topic. I’m not sure where to look for reliable information. I searched for charging circuit diagrams but didn’t find useful results, so I thought it would be best to ask someone more experienced for advice.
You might need to contact Dell for more details. There are no published figures on C ratings for the battery, and additional adapters may be available. A 65W charger is suitable for the 15.2V 54Wh battery, though it could be the maximum capacity. A higher wattage charger like 125W should work fine without damaging the laptop. Your MSI charger likely wouldn't fit either.
Hi there. I'm using an adapter from 7.4mm to the standard 4.5mm because that's what the Katana requires, which should also work with the Inspiron. The laptop is mainly for business trips and I also use a 65w charger that I need to travel with, so it seems like a good deal now that I might only need one charger at all.
The load, in this instance a laptop, only consumes what it requires at that time. A bigger power source doesn't help much other than creating more heat and adding weight to your bag. Clearly, your new compact device is more energy-efficient, shown by its smaller power adapter.
I'm not sure about increasing heat output. It really depends on how efficient the power supply is. High-power gaming power bricks tend to be more premium to keep them compact. The main concern is whether the laptop can charge faster than 65W. If it can, the bigger brick might serve a specific purpose for Dell. But if he's using both laptops, he's reducing the weight of carrying two.
