10 Best Compact Portable Chargers 2025 in the United States

The INIU Portable Charger is a great choice if you want a powerful yet lightweight power bank for everyday use and travel. Its 10,000mAh capacity is enough to recharge most smartphones once or twice, which fits well for moderate daily use. What stands out is its compact size and light weight—at just 8.8 ounces and about 5 x 2.7 inches, it slips easily into pockets or bags without feeling bulky.

The charger supports fast charging with a strong 45W output, meaning it can quickly boost devices like the latest iPhones to 60% in about 25 minutes. It also has two USB-C ports plus one USB-A port, letting you charge up to three devices at the same time, which is handy when you have multiple gadgets. Another unusual feature is that both USB-C ports can be used for input and output, offering flexible charging options. The safety aspect is well-covered by INIU's high-quality materials and built-in protections, making it reliable for frequent use. Bonus features like indicator lights and a small flashlight add convenience.

While 10,000mAh is portable, it might feel limiting if you need multiple charges for bigger devices like tablets or if you travel long-term without access to power. If your priority is a compact, fast, and safe power bank to keep your phone and small devices topped up on the go, this INIU model fits the bill nicely.

This portable charger is a solid choice for anyone needing a compact and versatile power bank. It offers a 10,000mAh capacity, which is enough to charge most smartphones about two times, making it suitable for daily use or short trips. One of its main strengths is the built-in cables—three different types included—so you don’t have to carry separate charging cords for different devices.

It also has six output ports in total, allowing you to charge up to six devices at once, which is convenient if you carry multiple gadgets or want to share with others. The charger is quite slim and lightweight (about half a pound), roughly the size of a large smartphone, so it fits easily in a bag or pocket. It features a clear digital display that shows exactly how much charge is left, helping you avoid surprises. The multiple input options mean you can recharge the power bank quickly using different cables. Compatibility is broad, covering iPhones, Samsung, Google Pixel, and many other USB-C or micro USB devices.

This product is a practical, multi-device charger that balances portability and capacity well, though users who need very fast charging or larger capacity might look elsewhere.

The Anker 621 Magnetic Portable Charger is a compact and lightweight power bank with a 5,000mAh capacity, making it ideal for on-the-go charging without adding much bulk. Its slim design and strong magnets let it snap securely to the back of compatible iPhones (12 through 16 series), which is great if you want hassle-free wireless charging that stays connected even while using your phone. It includes a USB-C cable for wired charging and supports fast input charging to refill itself quickly.

Weighing just 5 ounces with small dimensions, it easily fits in pockets or bags, perfect for daily carry. Safety-wise, it meets international standards and can get warm during use, but this is normal and not a risk. The build feels solid enough for regular use, though it’s mostly plastic, so handle with care. While the battery size is enough for about one full charge of most iPhones, it may not suit heavy users needing multiple charges.

Its wireless feature and magnetic attachment are standout conveniences, but it’s limited to iPhone models with MagSafe compatibility and won’t charge other devices wirelessly. This charger is best suited for iPhone users who want a portable, easy-to-use power bank for occasional top-ups rather than heavy power demands.
