10 Best Portable Battery Chargers 2025 in the United States

The Anker 621 Magnetic Portable Charger (MagGo) is a compact and convenient power bank designed specifically for iPhone users, particularly those with models from the iPhone 12 series onwards. With a battery capacity of 5,000mAh, it offers a decent amount of additional charge, which can be especially useful for short trips or daily use. One of its standout features is the strong magnetic attachment, which ensures it stays securely attached to the back of your phone, making it easy to take selfies, make calls, and more without fumbling with cables.

The compact size (4.13 x 2.62 x 0.45 inches) and lightweight design (5 ounces) make it highly portable, fitting easily into pockets, purses, or bags. It's particularly suitable for users who prioritize portability and ease of use. The inclusion of a USB-C to USB-C cable is a nice touch, providing flexibility in how it can be used and charged. The charger also comes with a 24-month warranty, adding a layer of reassurance for buyers.

However, the 5,000mAh capacity may not be sufficient for users who need more power for extended periods away from a power source. Additionally, while the wireless charging feature is convenient, it can sometimes lead to slight heating due to efficiency losses in the conversion circuit. Anker is known for its reliable build quality and safety features, which likely extend to this product as well.

The VRURC Portable Charger stands out with its 10000mAh capacity, making it a reliable choice for most smartphones and tablets, ensuring multiple charges on the go. One of its key strengths is the built-in cables (Micro USB, USB C, and iPhone) and an AC wall plug, providing significant convenience as you don't need to carry extra cables or an external charger.

The addition of both USB and USB C ports further enhances its versatility, allowing you to charge various devices simultaneously. Another appealing feature is its slim and compact design, measuring 5.9 x 2.8 x 0.7 inches and weighing just 8 ounces, making it easy to carry around without adding much weight to your bag. The smart digital LED display is also useful for quickly checking the remaining power, and the 3D texture improves the grip, preventing slips.

There are a few drawbacks. The charging speed might not be the fastest available, which could be a concern if you need a quick recharge. Additionally, while it includes basic safety features inherent in most power banks, the specifics are not detailed, which might raise questions about its long-term reliability. Ideal for travelers and daily use, the VRURC Portable Charger offers a blend of convenience, capacity, and portability, though those needing ultra-fast charging might want to look elsewhere.

The Charmast Portable Charger is a versatile 10,000mAh power bank tailored for travel with built-in cables and a wall plug, catering to a wide range of devices, including iPhones, Samsungs, and iPads. Its capacity is enough to fully charge an iPhone 13 approximately 1.6 times and a Samsung S22 Ultra once, making it suitable for a day's worth of power needs. The charger features multiple built-in cables (USB C, micro) and additional USB C and USB A ports, offering flexibility and faster charging options.

The LCD display is a helpful feature that lets you monitor the remaining power easily. The charger also supports pass-through charging, allowing you to charge both the power bank and your device simultaneously, which is handy for overnight charging. However, note that the max output during pass-through charging drops to 1A, which might result in slower charging speeds. The slim and compact design, weighing only 8 ounces, makes it highly portable and easy to carry in a pocket or bag.

Safety features are not explicitly mentioned, but the product promises 24-month support and friendly customer service, which suggests reliability. On the downside, the integrated cables may not suit every user's preference, and the limited 10,000mAh capacity might not be sufficient for users needing more extended power supply. This charger is a solid choice for travelers or anyone needing a compact, all-in-one charging solution, but might fall short for heavy users requiring higher capacity.
