Compatibility Notes & Usage Tips
Before purchasing, please ensure:
Original adapter label: Check the label on your current laptop adapter — it should state “Output: 19 V 4.5 A” (or very close) for proper compatibility.
DC tip size: Verify those numbers on your laptop’s charging socket or original adapter to make sure the barrel tip is 5.5 mm × 1.7 mm. A mismatch can cause loose connection or damage.
Wattage requirement: If your laptop originally required a higher wattage (for example 65 W or 90 W) then this 45 W unit may lead to slower charging or under-performance under load.
Use a good surge protector or voltage stabiliser: Given Bangladesh’s fluctuating power, using a stabiliser helps prolong both the adapter and your laptop’s life.
Ventilation matters: Avoid placing the adapter under pillows or in poor ventilation areas — allow it to breathe and dissipate heat.
Warranty claim: Keep your purchase receipt, warranty card and follow the local support instructions — physical damage, liquid damage or misuse may void the warranty.
Why Choose This Adapter?

Compatible and reliable power delivery tailored for Acer laptops.
Safe performance backed by proper protections and verified components.
Local warranty (12 months) — reducing the risk of unserviceable imports.
