65W: Great for lightweight laptops like MacBook Air；100W: Covers most high-performance laptops.；140W: Needed for ultra-high-performance laptops and full-speed PD 3.1 charging.
Choose a power bank based on your laptop’s max input and daily workload.
-
Can a Laptop Power Bank Damage My Laptop Battery?
No, if you pick a high-quality, compatible power bank with proper voltage regulation and USB-C PD support. Low-quality or unstable power banks can wear the battery over time. Always choose certified power banks with protections.
-
Why Does My Power Bank Provide Fewer Charges Than Expected?
External batteries typically deliver 60%-70% of their rated capacity.
30%-40% is lost to heat from voltage conversion and circuitry, which reduces the number of full charges for your device.
-
How to Calculate the Possible Number of Charges?
Formula: (Rated capacity × 65%) ÷ Device battery capacity ≈ Number of Charges.
Example: (20000mAh × 0.65) ÷ 3692mAh ≈ 3.5 charges for iPhone 17.
-
Does It Support Pass-Through Charging?
Yes. The power bank supports pass-through charging, allowing you to charge the power bank and connected devices at the same time.
