Running out of battery on your laptop or phone while away from an outlet is a modern frustration. While standard portable chargers (power banks) have been around for years, many struggle to provide enough power for anything more demanding than a smartphone. Enter the era of USB-C PD power banks, finding the best USB-C power banks allows leveraging the USB Power Delivery standard to offer high-wattage output capable of charging laptops, tablets, and fast-charging phones effectively on the go.
But with varying capacities, wattages, ports, and features, choosing the best power bank can be confusing. This MTI Software guide breaks down the essential features to look for and reviews some of the top USB-C PD power banks available in April 2025, helping you find the perfect portable power solution.
Why You Need a PD Power Bank for Laptops & Fast Charging
Traditional power banks often output power via USB-A ports, typically limited to 5W, 10W, or maybe 18W. This is sufficient for slowly charging phones but woefully inadequate for most laptops, which might require 45W, 65W, 100W, or even more.
USB-C PD power banks utilize the Power Delivery standard via their USB-C ports to:
- Deliver significantly higher wattage output.
- Intelligently negotiate the correct voltage and current for the connected device.
- Enable fast charging for compatible phones and tablets.
- Provide enough power to charge many laptops at near full speed.
Choosing the Best PD Power Bank: Key Factors
Consider these specs when comparing options:
Capacity: mAh vs. Wh (Watt-hours)
- mAh (milliamp-hours): Commonly advertised but less useful for comparing different voltage outputs. A 20,000mAh bank might power a phone many times but struggle with a laptop depending on its output voltage.
- Wh (Watt-hours): The most accurate measure of total stored energy (Wh = mAh * Voltage / 1000). This gives a better idea of how many laptop charges (or partial charges) you might get.
- Flight Limits: Be aware of airline regulations, typically limiting carry-on batteries to 100Wh (around 27,000mAh at typical voltages) without prior approval.
Output Wattage (Max Per Port & Total)
- CRUCIAL for Laptops: The USB-C PD port must have a maximum output wattage meeting or exceeding your laptop’s requirements (e.g., 65W USB-C PD, 100W USB-C PD, or even 140W+). Check your laptop’s original charger or specs. [See: Choosing the Right USB-C Charger Wattage].
- Total Output: If the power bank has multiple ports, check the maximum combined output and how power is distributed when multiple ports are used simultaneously.
Input Wattage (Recharging Speed)
- How fast can the power bank itself recharge? Look for high PD input wattage ratings (e.g., 30W, 65W, 100W) via USB-C for quicker turnaround times. Recharging a high-capacity bank with a slow charger takes many hours.
Number and Type of Ports
- Essential: At least one high-wattage USB-C PD port (often serves as input and output).
- Useful: Additional USB-C ports (may have lower wattage output) and USB-A ports for legacy devices.
Supported Standards (PD, PPS)
- USB PD: Ensure support for PD 3.0 or 3.1.
- PPS (Programmable Power Supply): Look for explicit PPS support if you want the absolute fastest charging speeds for compatible devices like many Samsung Galaxy and Google Pixel phones. [See: Understanding USB PD 3.0 vs 3.1 and PPS].
Size, Weight & Portability
- Higher capacity (mAh/Wh) and higher wattage output generally mean a larger, heavier power bank. Find the right balance for your needs – a massive 140W/27,000mAh bank is powerful but less pocketable than a 30W/10,000mAh unit.
Extra Features
- Digital Display: Shows remaining percentage, sometimes input/output wattage.
- Built-in Cables: Some models include integrated USB-C or Lightning cables.
- Wireless Charging: Qi or MagSafe compatible charging pads on the bank itself.
- Pass-Through Charging: Ability to charge devices while the power bank itself is recharging.
- Ruggedness/Water Resistance: Features for outdoor use.
Safety & Brand Reputation
- Look for safety features like overcharge, over-discharge, over-current, over-voltage, and temperature protection.
- Stick to well-regarded brands known for battery safety and quality, such as Anker, UGREEN, Baseus, Zendure, Belkin, Mophie, INIU, etc.

Understanding Real-World Charging Capacity
Remember that advertised mAh capacity doesn’t directly translate to delivered power due to voltage conversion and energy loss (heat). Expect roughly 60-70% efficiency. A 100Wh power bank might realistically deliver ~60-70Wh to your devices. Check your laptop’s battery capacity (in Wh) to estimate how many charges (or partial charges) you can expect.
Conclusion
A USB-C PD power bank is an essential tool for keeping power-hungry devices like laptops and fast-charging phones alive while mobile. The key is to look beyond just mAh capacity and focus on the maximum PD output wattage (matching your most demanding device, typically 65W or 100W for laptops) and the total energy stored (Wh), keeping airline limits in mind. Features like high input wattage for fast recharging, PPS support for compatible phones, and multiple ports add significant value.
By assessing your specific needs and choosing a quality power bank from a reputable brand that meets the required PD wattage and capacity, you can confidently power your devices wherever you go.
