Never Run Out of Battery Again
Modern devices drain faster than ever with always-on displays, 5G connectivity, and power-hungry apps. A quality power bank ensures your phone, tablet, laptop, and even gaming handheld stay charged through long days, travel, and emergencies. The latest power banks charge at speeds that rival wall chargers and pack enough capacity to charge a laptop multiple times.
Anker Prime 27,650mAh: Best High-Capacity ($159)
The Anker Prime packs a massive 27,650mAh battery with 250W total output across two USB-C ports and one USB-A. The headline feature: 140W single-port USB-C output that charges MacBook Pros and other USB-C laptops at near full speed. The display shows real-time power delivery for each port, remaining capacity as a percentage, and estimated time to empty or full. It recharges itself at 170W, going from empty to full in about 60 minutes. Build quality is excellent with a matte aluminum shell and compact size relative to its capacity.
Baseus Blade 20,000mAh: Best Slim Design ($79)
The Baseus Blade is remarkably thin at just 18mm, fitting into laptop bags and jacket pockets where bulkier power banks would not. Despite the slim profile it delivers 100W USB-C output for laptop charging and 65W input for fast self-recharging. The 20,000mAh capacity charges a typical smartphone 4-5 times or provides a full laptop charge. The LED display shows percentage and watts being delivered. At $79 it offers the best balance of capacity, power delivery, portability, and price.
Ugreen Nexode 12,000mAh: Best Travel Companion ($49)
The Ugreen Nexode 12,000mAh is purpose-built for travel: compact enough for a pocket, 100W output for emergency laptop charging, built-in foldable AC prongs for direct wall outlet charging without a separate cable, and airline-safe capacity under the 100Wh carry-on limit. The 12,000mAh provides 2-3 full smartphone charges or one partial laptop charge. It replaces both your wall charger and power bank in a single device, saving pack space and weight.
Choosing the Right Capacity
Divide the power bank mAh by your device battery mAh and multiply by 0.7 (accounting for conversion losses) for approximate charge count. A 20,000mAh bank provides roughly 3.5 charges for a 4,000mAh phone. For laptop charging, look at watt-hours: a 100Wh power bank provides about one full charge for a typical ultrabook. If you primarily charge phones, 10,000-20,000mAh covers a full day. If you charge laptops, aim for 20,000mAh+ with 65W+ USB-C output.
Our Picks
For maximum capacity and power: Anker Prime. For slim portability with laptop charging: Baseus Blade. For the best all-in-one travel charger: Ugreen Nexode. All three use GaN technology, support PD 3.0 and PPS fast charging protocols, and work with any USB-C device from phones to laptops to gaming handhelds.
