10 Best Usb Battery Chargers 2025 in the United States

The Anker PowerCore 10K is a compact and travel-friendly power bank with a 10,000mAh capacity, offering a good balance between portability and enough power to recharge an iPhone 12 around twice or provide 1.6 full charges for a Galaxy S20. It features 12W optimized charging output through Anker’s PowerIQ and VoltageBoost technology, which helps speed up charging for compatible devices. This power bank includes one USB-C port and one USB-A port, making it versatile for different device cables, though it lacks multiple ports for charging several devices simultaneously.

It’s lightweight (7.4 ounces) and slim enough to comfortably fit in a pocket, which is great for users needing convenient on-the-go charging without bulk. The PowerCore 10K also includes safety features like multi-layer protection against overcharging and overheating, providing peace of mind during use. However, it only supports USB-C input for recharging itself, and the package comes with a Micro USB cable to charge the power bank, meaning you may need to use or buy separate cables for your devices. It does not include USB-C or Lightning cables for device charging.

Offering reliable fast charging and durability with a scratch-resistant design, the power bank is ideal for travelers and everyday users who want a dependable, easy-to-carry charger for one or two devices rather than a multi-port powerhouse. Users requiring multiple device charging at once or higher output power for faster charging might find it less suitable.

The VRURC Portable Charger with a 20000mAh capacity is a high-capacity power bank designed for those who need reliable and fast charging on the go. One of its standout features is the built-in AC wall plug and cables, including options for micro USB, USB-C, and iPhone, making it highly convenient for travelers who may forget to bring extra cables.

The power bank supports up to 22.5W fast charging, which is efficient for quickly juicing up your devices, and can charge up to three devices simultaneously. Its intelligent LED display helps you keep track of the remaining battery life, ensuring you’re never caught off guard with a dead power bank. Additionally, it offers multiple safety protections like overcharge and short-circuit protection, providing peace of mind when using it with your devices.

However, it is relatively bulky, weighing 0.81 lb and measuring 5.91 x 2.83 x 1.09 inches, which might be less convenient for those looking for a more compact solution. It takes a fairly long time to recharge, with two ways to do so: via the AC wall plug in about 11 hours or using a 9V/2A charging cable in about 6 hours. This charger is best suited for users who need to charge multiple devices and appreciate built-in cables for added convenience, especially during travel.

The Anker Power Bank with a 26,800 mAh capacity offers plenty of power to keep multiple devices charged during long days away from outlets. With three USB-A output ports, it allows you to charge three devices simultaneously, which is great if you have several phones or tablets. Thanks to Anker’s PowerIQ and Voltage Boost technology, charging speeds are solid for USB-A devices, though it doesn't support the faster Qualcomm Quick Charge standard.

One downside is the absence of a USB-C port, so if you have newer devices that charge via USB-C, you'll need to use a USB-A to USB-C cable, which might feel a bit outdated compared to more modern chargers. The power bank recharges quite quickly due to its dual micro-USB input ports, taking just over six hours to fully charge when using both inputs together. However, you’ll need to supply your own wall charger since one isn’t included. It’s a bit on the heavier side at around 1.1 pounds and measures about 7 by 3 inches, so it’s more suited for backpacks or bags rather than pocket carry.

The package includes two micro-USB cables but does not include USB-C or Lightning cables, so buying those separately may be necessary depending on your devices. Anker’s reputation and a strong customer rating of 4.6 stars among nearly 39,000 reviews reflect reliability and good user satisfaction. This power bank suits users who want a high-capacity charger capable of handling multiple devices at once and don’t mind sticking with USB-A connections. If you prioritize USB-C ports or a lighter, more compact design, you might want to consider other options.
