10 Best Fastest Portable Charger 2025 in the United States

The Anker Zolo Portable Charger offers a robust package with a 10,000mAh capacity, which is enough to fully charge an iPhone 15 twice or a Samsung S24 nearly twice. Its standout feature is the 30W fast charging capability, which can charge an iPhone 15 up to 57% in just 30 minutes, making it a strong contender in the 'fastest portable charger' category.

The built-in USB-C cable is a convenient touch, especially for travelers, and has been tested to withstand over 10,000 bends, adding to its durability. The compact size of the power bank makes it easy to carry around without adding much bulk to your bag. It also supports bi-directional charging—up to 30W output and 20W input—so you can charge the power bank itself quickly as well as your devices.

However, it does have some limitations. It only comes with one built-in USB-C cable, which might not be enough for users who need to charge multiple devices simultaneously. Additionally, some might find the 10,000mAh capacity somewhat limiting for longer trips if you are planning to charge larger devices like a MacBook or iPad multiple times. Despite these minor drawbacks, the Anker Zolo Portable Charger excels in providing quick and efficient power on the go, making it a solid choice for those in need of a fast and reliable portable charging solution.

The INIU Portable Charger is a strong candidate in the fast portable charger category, designed with travelers and daily users in mind. With a 10,000mAh capacity, it offers ample power to recharge devices multiple times, such as giving an iPhone 8 nearly 4 full charges. One big advantage is its slim design, measuring just 0.5 inches thick, which makes it incredibly easy to slip into pockets or bags without adding bulk. Additionally, it features a USB-C port that supports both input and output, allowing you to charge your devices faster and with fewer cables, as many competitors only provide USB-C for input.

Charging speed is another highlight, with a 3A output that promises to charge compatible devices significantly faster than standard 2.1A chargers—up to 78% for an iPhone in just an hour. This can be a game-changer for users who need a quick power boost on the go. Furthermore, the 15-Layer SmartProtect system enhances safety by preventing overheating and potential battery damage, adding an extra layer of security to your charging experience.

There are some drawbacks to consider. While the charger’s size is impressive, the 10,000mAh capacity might be limiting for heavy users who rely on extensive charging throughout the day or during long trips. Additionally, although the charger is lightweight at only 7 ounces, it may still feel slightly heavier compared to smaller capacity chargers. Lastly, while the provided USB-C cable is a nice touch, having only two output ports could be a limitation for users needing to charge multiple devices simultaneously.

The Charmast Portable Charger is a compact and versatile option for anyone needing to keep their devices charged while on the go. With a capacity of 10,000mAh, it provides ample power to recharge most smartphones multiple times. One of its standout features is the built-in cables, which eliminate the need to carry multiple charging cords. This is particularly handy for users with different devices, as it includes cables for iPhone, USB Type-C, and Micro USB. The slim profile (5.68''x2.63''x0.69'' and only 0.55lb) makes it easy to slip into a bag, making it a great travel companion.

The charger has six outputs, allowing up to six devices to be charged simultaneously, which is ideal for families or groups who need to keep several gadgets powered up. The presence of three input options adds convenience, letting users recharge the power bank through various methods. The digital LED display is a useful touch, providing an accurate percentage of remaining battery life, so you know when to recharge.

The 3A charging speed is not the fastest available on the market; those looking for ultra-fast charging may find it a bit lacking. Additionally, with a capacity of 10,000mAh, it may not suffice for heavy users who require more power for high-drain devices or extended trips without access to power. The Charmast Portable Charger is an excellent choice for casual users who need a reliable and portable solution to keep their devices powered.
