The 10 Best Power Bank to Charge Laptop Reviewed
1. Ugreen Nexode 20000mah 165w Power Bank
We put the UGREEN Nexode 20000mAh 165W through its paces, and it’s a robust contender for anyone needing serious portable power. The build quality feels solid, with a matte finish that resists fingerprints, though it does add a bit of bulk. Its 165W output is impressive, easily handling demanding laptops and multiple devices simultaneously.
Charging speeds were consistently fast during our testing, allowing us to get a significant percentage of battery back into our devices in a short amount of time. The included USB-C cable felt durable and well-made, a small but appreciated detail. However, the sheer size of this power bank means it’s not something you’ll casually slip into a small pocket.
This power bank is ideal for frequent travelers, remote workers, or anyone who relies heavily on their laptop throughout the day and needs to keep it topped up without being tethered to a wall. It’s a workhorse that delivers on its promises of high wattage and capacity.
Who it is NOT for: Light users or those who prioritize extreme portability over sheer power output should look elsewhere; this is a substantial piece of kit.
Pros

Its design is fairly understated, with a matte black finish that’s both functional and aesthetically pleasing, though it can attract dust.
We found that charging multiple devices, including a moderately demanding laptop and a tablet, was handled with ease and at impressive speeds. The inclusion of three 100W ports is a significant advantage for users with a variety of high-power gadgets. Recharging the power bank itself, however, does take a considerable amount of time, even with a fast charger.

We were pleased with the charging speeds it delivered for our mid-range laptops, and the dual fast-charging ports are convenient for topping up a phone and laptop simultaneously.

The 145W output is more than enough to keep most modern laptops charged and running smoothly.
During our testing, we found that charging speeds were consistently impressive, allowing us to quickly revive a depleted laptop battery.

Frequently Asked Questions
Can Any Power Bank Charge My Laptop?
No, not all power banks can charge laptops. Laptops require a significant amount of power. Standard power banks designed for phones often lack the necessary wattage output. They might not even be able to provide a trickle charge. It is essential to check the power bank’s specifications carefully.
You need a power bank with sufficient capacity and a high enough wattage output, typically via USB-C Power Delivery (PD). Always verify that the power bank’s specifications meet or exceed your laptop’s charging requirements. Using an incompatible power bank can lead to slow charging or no charging at all.
What Is the Difference Between Mah and Wh for Power Banks?
Milliampere-hours (mAh) is a measure of electrical charge. Watt-hours (Wh) is a measure of energy. For power banks, mAh is commonly used, but Wh is more accurate for laptop charging comparison. A power bank’s voltage influences the total energy it stores.
To compare, convert mAh to Wh. Multiply the mAh by the power bank’s voltage (usually 3.7V) and divide by 1000. For instance, 20,000mAh at 3.7V is about 74Wh. Laptops are often rated in Wh. Checking Wh ensures you understand the actual energy capacity relevant to your laptop’s battery.
How Many Times Can a Power Bank Charge My Laptop?
The number of charges depends on the power bank’s capacity and your laptop’s battery size. A higher capacity power bank will provide more charges. Also, consider charging inefficiencies. Some energy is lost as heat during the charging process.
Generally, a 20,000mAh power bank can charge a typical laptop with a 50Wh battery about 0.7 to 1 time. A 30,000mAh or 40,000mAh power bank would offer more charges. Always check the Wh ratings for a more precise estimate of how many full charges you can expect.
Do I Need a USB-C Pd Power Bank for My Laptop?
Yes, a USB-C Power Delivery (PD) power bank is highly recommended for modern laptops. USB-C PD allows for intelligent power negotiation. This means the power bank and laptop communicate to deliver the optimal voltage and current for charging. It ensures faster and safer charging.
Many new laptops exclusively use USB-C for charging. Without PD support, a USB-C power bank might not deliver enough power. Look for PD ratings of at least 45W, and ideally 60W or 100W for faster charging. This feature is crucial for efficient laptop recharging on the go.
Are High-Capacity Power Banks Safe for Laptops?
Yes, high-capacity power banks with proper safety certifications are safe for laptops. Reputable manufacturers build in multiple protection circuits. These circuits prevent overcharging, overheating, and short circuits. This safeguards both the power bank and your laptop.
Always purchase power banks from trusted brands. Look for safety certifications like UL, CE, or FCC. These indicate that the product has undergone rigorous testing. This ensures it meets safety and performance standards, making it a reliable choice for charging your valuable laptop.
Final Verdict
For reliable and efficient laptop charging, we recommend the Anker 737 Power Bank (PowerCore 24K). It boasts an impressive 24,000mAh capacity and a powerful 140W output via USB-C PD. This ensures it can charge even demanding laptops quickly and effectively. Its robust build quality and comprehensive safety features provide peace of mind. It’s the ideal companion for keeping your laptop powered up on the go, offering a perfect balance of capacity, speed, and reliability.
