10 Best Fastest Portable Charger 2025 in the United States

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.

This portable charger offers a solid balance of fast charging, capacity, and portability. With a 12,000mAh battery, it can provide roughly 2 to 3 full charges for most smartphones, making it suitable for daily use or travel. Its charging speed is impressive, supporting up to 22.5W output on multiple ports, including built-in USB-C and USB-A, allowing you to charge devices quickly—like an iPhone 13 reaching 50% in about 25 minutes. The dual recharging options are convenient: a built-in AC wall plug for charging the power bank itself in around 5 hours, or a Type-C port for a faster 4-hour recharge, which is handy when you’re on the go.

The device’s slim and lightweight design (approximately half a pound and less than an inch thick) makes it very portable and easy to carry in a pocket or bag. Built-in cables eliminate the hassle of carrying extra cords, which is great for travel or everyday convenience. The LED display clearly shows the remaining battery level, so you can monitor power without guessing. Safety features include protection against overcharging, overheating, and short circuits, ensuring peace of mind when charging your devices.

While the 12,000mAh capacity is decent, it is not the highest available, so for multiple charges of power-hungry devices or longer trips without access to power, larger capacity models might be more suitable. The charger supports fast charging well but maxes out at 22.5W, so it won’t be as speedy as some chargers offering 30W or more. This makes it an excellent all-around choice for most users seeking portability combined with fast and safe charging for a variety of devices like iPhones, iPads, and Samsung phones.

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.
