The Best Power Banks for 2025: Top Portable Chargers Tested
Finding the best power bank can be a challenge with so many options on the market. After testing around 50 portable chargers from brands like Anker, Belkin, UGreen, Mophie, and smaller players like Lion Energy and Nimble, we’ve narrowed down the top picks for 2025. Whether you need a compact battery for your phone or a high-capacity pack for your laptop, here’s what you need to know.
What to Look for in a Power Bank
Battery Type: Nearly all power banks use lithium-ion batteries, which offer high energy density and don’t suffer from memory effect. These are the standard for portable charging.
Capacity: Measured in milliamp hours (mAh), capacity determines how much charge a power bank can hold. Smaller banks (5,000mAh) are great for phones, while larger ones (25,000mAh+) can handle laptops and tablets. Keep in mind that efficiency isn’t 100%—expect around 60% of the rated capacity to actually reach your device.
Ports: USB-C is now the standard, but some banks still include USB-A for older devices. Look for multiple ports if you need to charge several gadgets at once.
Wireless Charging: Qi2-enabled power banks are becoming more common, offering faster wireless charging, though wired charging remains more efficient.
Design: Most power banks are brick-shaped, but some include extras like built-in cables, kickstands, or MagSafe compatibility.

Power Bank FAQs
Can You Take Power Banks on a Plane?
Yes, but only in carry-on luggage. The FAA limits power banks to 100Wh or less, which all our recommendations meet.
Does Fast Charging Damage Batteries?
Not significantly. While fast charging generates more heat, modern devices have safeguards to minimize damage. Still, occasional slow charging can help prolong battery life.
Can Power Banks Charge Laptops?
Yes, but only high-capacity models (20,000mAh or more) with sufficient wattage. Check your laptop’s power requirements before buying.
Final Thoughts
The best power bank depends on your needs. For most people, a 10,000mAh model strikes a good balance between capacity and portability. If you need more power, consider a 25,000mAh bank for laptops and multiple devices. Wireless options are convenient but slightly less efficient. Whatever you choose, make sure it fits your lifestyle and charging habits.
