Anker Prime 20,000mAh Power Bank
Pros: Handy screen with menu system, awesome power output, fast charging (with a 100W adapter).
Cons: Some buggy behaviors at maxed-out charging, dodgy level reporting out of the box, high price for a 20K battery.
The Anker Prime 20,000mAh power bank is a top-tier option for those seeking advanced features. It boasts a full-color screen displaying battery capacity and charge speeds for its two USB-C (100W each) and one USB-A (65W) ports. It can charge laptops and phones simultaneously and recharges in approximately 56 minutes with a 100W charger. Its large capacity is suitable for multiple phone charges, though its size makes it more of a rucksack accessory.
Ugreen Nexode 100W 20000mAh Power Bank
Pros: 100W charging, solid efficiency, fairly convenient shape and size.
Cons: Limited display functionality, scuff-prone finish, secondary outputs' power limited when used together.
The Ugreen Nexode 100W offers a 20,000mAh capacity and 100W output via its primary USB-C port. While its display is simpler than the Anker Prime's, it provides remaining battery life.

Anker Nano Power Bank 30W
Pros: Slick integrated display, solid capacity for size, fills up fairly quickly.
Cons: Making a cable a handle is not sensible, efficiency could be slightly higher, not quite premium.
The Anker Nano Power Bank 30W is a compact and stylish option with an integrated USB-C cable that doubles as a handle. It features an invisible screen behind its frosted plastic exterior, showing output, battery levels, and estimated charge time. It includes a secondary USB-C port and a USB-A port. While its efficiency is around 76.9%, it's sufficient for fully charging most smartphones. It's a good choice for portability, though more expensive than some alternatives.

It offers two USB-C ports capable of 65W charging when plugged into a wall, or 30W when running on battery. It also includes a USB-A port. Its ability to charge multiple devices, including laptops, makes it ideal for travelers. While bulkier than some options, its dual functionality is a significant advantage.

The Iniu PD Power Bank offers a large 20,000mAh capacity at an affordable price. It features a USB-C port and two USB-A ports for simultaneous charging of multiple devices. While its 22.5W charging speed is suitable for iPhones, it's slower than many modern Android phones and cannot charge a MacBook. Its sleek design and LCD screen for charge monitoring are notable features, though it is relatively bulky and heavy.
Baseus Magnetic Foldable Power Bank
The Baseus Magnetic Foldable Power Bank features a strong magnet for secure attachment to iPhones and supports Apple's StandBy mode when used as a dock. It offers 10,000mAh capacity and a USB-C port capable of 20W charging. However, its wireless charging speed is slow at 7.5W. Despite this, its strong magnetic hold and portability make it a good option for those prioritizing convenience and a dock-like experience.
Baseus Airpow Power Bank
The Baseus Airpow Power Bank is an affordable option, starting at $20, with a 10,000mAh capacity. It includes two USB-C ports (one at 20W) and one USB-A port, allowing for multi-device charging. While not the fastest charger, its value and port selection make it a compelling choice for budget-conscious users. Its design is sleek, but it requires carrying separate cables.
Otterbox 2-in-1 Power Bank with Apple Watch
This unique 3,000mAh power bank is specifically designed for Apple Watches, featuring a magnetic attachment that allows the watch to function as a desk clock while charging. It also includes a USB-C port for 15W charging of other devices. While its capacity is insufficient for fully charging a smartphone, it's ideal for users prioritizing Apple Watch battery life and convenience.
Tylt Bottle 2
The Tylt Bottle 2 combines a 5,700mAh power bank with an insulated water bottle. It offers wireless charging via a puck on the bottle and also includes USB-C and USB-A ports. This combination is convenient for students or cafe-goers who need to charge devices on the go. While its capacity is modest and charging speeds are slow, its dual functionality makes it a practical choice for everyday use.
How to Choose the Best Power Bank
When selecting a power bank, consider that they typically offer about 70% of their stated capacity due to power transfer inefficiency. For fast charging, ensure the power bank's wattage matches your phone's charging port. Reputable brands like Anker, Baseus, and Otterbox are recommended for reliability and durability. Choose based on your charging needs, whether it's for a smartphone, laptop, or multiple devices, and consider features like wireless charging or built-in cables.
