10 Best Fastest Portable Charger 2025 in the United States

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.

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 Anker Laptop Power Bank is a robust and versatile portable charger that excels in power capacity and multi-device charging. With a massive 25,000mAh capacity, it can keep your devices powered for extended periods, making it ideal for long trips or heavy usage scenarios. The standout feature is its triple 100W USB-C ports, allowing you to charge multiple devices like a MacBook and smartphones simultaneously, which is a significant advantage for multitaskers or those with several devices.

Additionally, it comes with dual built-in and retractable cables, designed to endure over 20,000 retractions and bends, offering convenience and durability for on-the-go usage. The power bank can also charge up to four devices at once, accommodating various USB-enabled gadgets. However, its size and weight (1.31 pounds and dimensions of 6.18 x 2.13 x 1.93 inches) may be slightly bulky for users seeking a more compact solution. Despite this, its fast recharging capability (100W ultra-fast recharging to 30% in 20 minutes) and built-in digital display add to its user-friendly design.

The Anker Laptop Power Bank is well-suited for users who need high capacity and fast charging for multiple devices, though it may not be the most portable option for those prioritizing minimal size and weight.
