FAQ
Will this make my charger compatible automatically?
It adapts the connector size, but your charger must still have the correct voltage and enough wattage for your laptop.
Does this convert power (voltage) too?
No. This is a physical connector converter only.
How do I confirm the correct size?
Check your old charger tip size (7.4×5.0mm vs 4.5×3.0mm) and compare it with your laptop’s required connector before buying.
