High-wattage power banks are portable chargers engineered to deliver significantly more power than standard models, typically ranging from 65W to 140W (or higher).
While a standard power bank is designed primarily for smartphones, high-wattage versions are built to charge power-hungry devices like laptops, tablets, and high-end handheld gaming consoles.
The core technology behind these devices is Power Delivery (PD), a fast-charging standard that allows for higher voltage and current over a USB-C connection.

Why You Would Use One
- Laptop Charging: A 65W power bank can keep a laptop running during a long flight or at a coffee shop without outlets.
- Gaming Handhelds: Devices like the ASUS ROG Ally or Lenovo Legion Go require high wattage to maintain performance while charging.
- Fast Recharging: High-wattage power banks often support high-wattage input. This means you can recharge the power bank itself in 1–2 hours rather than 6–10 hours.
- Multi-Device Charging: They can often split their power across multiple ports, charging a laptop, phone, and tablet simultaneously.
