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.

The Anker Prime Power Bank stands out as a top choice for those seeking a fast, portable charger with plenty of power. With a high capacity of 26,250mAh, it offers enough juice to nearly fully charge a MacBook Pro once, which is impressive for a compact device weighing just about 1.3 pounds. Its claim of a 300W max output across three ports (two USB-C and one USB-A) means you can charge multiple devices simultaneously at high speeds, including fast charging a laptop or the latest iPhone models. The 140W max fast charging for laptops is particularly notable, allowing a MacBook and iPhone to reach 50% charge in roughly half an hour.

Another highlight is the ultra-fast recharge feature, with the power bank topping back up to 50% in only 13 minutes, which is great if you’re on the go and need quick top-ups. Size-wise, it’s compact and TSA-approved, making it easy to travel with, though the base for charging it is sold separately, which might be inconvenient for some. The smart display and app control provide useful info and let you adjust power output manually, adding convenience and control. Its compatibility with a wide range of devices, including recent MacBooks and iPhones, adds to its versatility.

A few considerations include the weight, which is heavier than smaller power banks and might affect ultra-light travel preferences. Also, since the charging base is not included, you might need to buy extra accessories for the fastest recharge experience. This Anker model is ideal for users who want a powerful, quick-charging portable charger that balances capacity and speed, especially for MacBook and iPhone users who need reliable performance on the move.

The Anker 621 Magnetic Portable Charger is a compact and lightweight power bank designed especially for iPhone 12 through 16 series users who want convenient wireless charging on the go. Its 5000mAh capacity provides enough power for roughly one full charge of an iPhone, making it a good choice for quick top-ups rather than multiple full charges. Thanks to Anker's MiniCell technology, it’s smaller and lighter than many competitors, fitting easily in your pocket or snapping securely to the back of your phone with strong magnets. This magnetic feature not only helps keep the charger in place but also allows you to use your phone normally without disruption.

Charging speed is decent for wireless power banks, quickly starting once aligned properly, although some slight heating during use is normal due to power conversion. The USB-C cable included adds versatility for wired charging if needed. Safety is covered with Anker’s reliable standards, protecting your phone and charger from common issues. However, the charger has only one output method—wireless charging via MagSafe—which limits compatibility with devices outside the iPhone MagSafe ecosystem.

If you want a small, stylish, and user-friendly charger specifically for newer iPhones, this is a solid pick. For those needing larger capacity or multiple device charging options, it may be better to consider other products.
