The 10 Best Laptop Portable Charger Reviewed
1. Anker Prime Power Bank, 26,250mah
We put the Anker Prime Power Bank, 26,250mAh 3 through its paces, and it certainly lives up to Anker’s reputation for robust portable charging.

Its build quality feels solid, with a matte finish that resists fingerprints, which is a nice touch.
During our testing, the charging speeds were consistently fast, especially when powering a connected laptop. The array of ports is generous, offering flexibility for various gadgets.

The matte black finish feels premium and comfortable to hold, and the unit feels well-constructed.
Charging performance was excellent, delivering consistent power output to connected devices. The inclusion of multiple USB-C ports is a welcome feature for simultaneous charging.

Charging speeds were respectable for its class, though not the absolute fastest we’ve seen for laptops.

The 165W output is the standout feature, making it suitable for even the most demanding laptops. We found the charging to be incredibly quick, significantly reducing downtime.

The triple 100W ports are a significant advantage, allowing for rapid charging of compatible laptops and other high-power devices.

The 165W output is more than enough to charge most laptops at a respectable speed, and the 20,000mAh capacity provided multiple charges for our test devices.

During our testing, we found the charging indicators to be clear and easy to understand, showing precise remaining battery percentages.

Frequently Asked Questions
What Is the Minimum Mah I Should Look for?
For most laptops, a minimum of 20,000mAh is recommended. This capacity can typically provide at least one full charge for a standard ultrabook. If you have a larger or more power-hungry laptop, consider units with 30,000mAh or more.
The actual number of charges depends on your laptop’s battery size and the charger’s efficiency. It’s wise to overestimate slightly to ensure you have enough power when needed.
Can a Portable Charger Charge My Laptop as Fast as a Wall Adapter?
Generally, a good portable charger with USB-C Power Delivery (PD) can charge your laptop nearly as fast as a wall adapter. The key is the charger’s wattage output. It must match or exceed your laptop’s original charger’s wattage.
Look for chargers that explicitly state their PD output in watts. 65W or higher is ideal for most modern laptops. Slower charging might occur if the wattage is insufficient or if you are using the charger while the laptop is under heavy load.
How Do I Know If a Portable Charger Is Compatible with My Laptop?
Check your laptop’s power adapter for its wattage and connector type. Most modern laptops use USB-C PD for charging. You need a portable charger with a USB-C PD port that outputs at least the same wattage as your laptop’s adapter.
Some older laptops might use proprietary barrel connectors. In such cases, you’ll need a universal laptop power bank that comes with multiple adapter tips, or a USB-C PD charger if your laptop supports it via an adapter.
Will a Portable Charger Overheat My Laptop?
No, a reputable portable charger will not overheat your laptop. Modern chargers and laptops have built-in safety mechanisms. These prevent overcharging, overheating, and excessive voltage. They communicate to manage power flow safely.
Always use chargers from trusted brands that meet safety standards. Avoid cheap, uncertified chargers, as they might lack these crucial protections. Following the manufacturer’s instructions is also important.
How Long Does a Portable Charger Take to Recharge?
Recharging a large capacity portable charger can take several hours. A 20,000mAh or 30,000mAh unit typically takes 4-8 hours to fully recharge. This depends on the charger’s input wattage and the power source you use.
Using a high-wattage wall adapter (like your laptop’s charger) will significantly speed up the recharging process. Some portable chargers also support pass-through charging, allowing you to charge the power bank and a device simultaneously.
Final Verdict
For the best overall laptop portable charger, we recommend a unit with at least 26,800mAh capacity and 65W USB-C Power Delivery output. This combination offers a great balance of portability and power, capable of fully recharging most ultrabooks and many larger laptops at a comparable speed to their original chargers. Prioritize models from reputable brands that clearly state their PD wattage and include essential safety certifications like UL. This ensures reliable performance and protection for your valuable devices, making it an indispensable companion for professionals and students on the go.
