Buying Guide: What to Look For in a Laptop Power Bank
Choosing the right power bank for your laptop involves more than just picking the first one you see. You need to consider capacity, output, and portability to ensure it meets your daily demands. Here are the essential criteria we used to evaluate our top picks.
Wattage and Output Speed
The wattage output determines how fast your laptop charges. A power bank with at least 60W output is ideal for most ultrabooks, while 100W or more is better for larger laptops or when you need a quick top-up. Look for models with Power Delivery (PD) support for efficient charging.
For example, the Anker Laptop Power Bank, 25,000mAh Travel offers a total output of 165W, with three 100W USB-C ports. This means you can charge your laptop and other devices simultaneously without slowing down. If you have a 14-inch MacBook Pro, this can get you to 50% in under 40 minutes, which is impressive.
Capacity and Portability
Battery capacity is measured in milliamp-hours (mAh). For laptops, you generally want at least 20,000mAh to get a full charge or two. However, higher capacity often means a heavier and bulkier device. Consider your travel needs: if you are always on a plane, a 25,000mAh power bank is a sweet spot, but it must comply with airline restrictions (under 100Wh).
The Anker Power Bank, 20,000mAh Travel Essential is a more compact option that still delivers 87W of power, making it easy to slip into a backpack. Both models from Anker are airline-approved, so you can travel with confidence. For more portable options, see our guide to the best portable chargers.
Number of Ports and Compatibility
Think about how many devices you need to charge at once. A power bank with multiple ports allows you to charge your laptop, phone, and earbuds simultaneously. Also, check for built-in cables, which save you from carrying extra cords. The Anker 25,000mAh model features two built-in USB-C cables, one retractable and one that doubles as a strap, adding convenience.
Compatibility is also key. Ensure the power bank supports the fast charging protocols for your specific laptop and phone. Most modern Anker models are versatile, but it is always good to double-check the specs. If you are into the latest tech, you might want to explore other electronics reviews for additional insights.
Build Quality and Durability
Since you will be carrying this power bank around, it needs to withstand daily wear and tear. Look for models with sturdy construction, reliable cables, and safety features like overcharge protection. Anker is known for its durable designs, and both of our top picks feature cables that have been tested for thousands of bends.
For example, the Anker 25,000mAh model’s retractable cable is rated for 20,000 retractions, while the 20,000mAh version’s built-in cable can endure over 10,000 bends. This level of durability ensures your investment lasts. For more budget-friendly options, check out our best power bank for the money guide.
Final Thoughts
When it comes to choosing the best power bank for laptop use, both Anker models we reviewed are excellent choices, but they serve different needs. If you need maximum power and the ability to charge multiple devices simultaneously, go with the Anker Laptop Power Bank, 25,000mAh Travel. For a more portable and budget-friendly option that still delivers fast charging, the Anker Power Bank, 20,000mAh Travel Essential is perfect. Consider your typical day and which features matter most to you, and you will find the perfect companion to keep your laptop and devices powered wherever you go.
Frequently Asked Questions
How many mAh do I need for a laptop power bank?
For most laptops, a power bank with at least 20,000mAh is recommended to get at least one full charge. If you have a larger laptop or want extra juice for multiple charges, consider a 25,000mAh or higher capacity. Remember to check the wattage output to ensure it is compatible with your laptop’s charging requirements.
Can I take a laptop power bank on a plane?
Yes, but there are restrictions. Power banks must be under 100Wh (watt-hours) to be allowed in carry-on luggage. The Anker 25,000mAh model is rated at 90Wh, and the 20,000mAh version is around 72Wh, so both are compliant. Always check with your airline for specific rules, as some may have different limits.
What is the difference between 65W and 100W output?
The wattage indicates how quickly a power bank can charge your devices. A 65W output is sufficient for most lightweight laptops, but it might charge slowly if you are using the device while charging. A 100W output is better for larger laptops like the MacBook Pro 16-inch, as it can deliver a full-speed charge. It also allows you to charge multiple devices without reducing the charging speed.
Are built-in cables reliable?
Yes, modern built-in cables are designed to be durable. Anker’s models feature cables that have been tested to withstand thousands of bends, so they are built to last. They also eliminate the need to carry extra cables, making them more convenient for travel. Just be sure to handle them with care and store them properly to extend their lifespan.
