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 RGVOTA 38800mAh Portable Charger stands out primarily for its massive capacity, making it an excellent choice for users who need to keep multiple devices charged throughout the day without frequent recharging. Its 38800mAh capacity is impressive and likely to power your phone several times over. Additionally, it offers versatility with 4 USB output ports and dual input options, including USB-C, which is great for compatibility with a wide range of devices including both iPhones and newer USB-C devices.

The digital display is a handy feature for keeping track of the remaining charge, and the built-in safety features like overcharge and short circuit protection add a layer of security for your devices. However, the charger is on the heavier side at 15.8 ounces and relatively large, which might be less convenient for portability. While it supports fast charging, the input speed is only 5V/2.1A, which means it might take a while to recharge the power bank itself.

The build quality seems robust, making it a solid choice for those heavily reliant on their devices throughout the day or for extended trips where access to power outlets is limited.

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.
