10 Best Fast Battery Chargers 2025 in the United States

The Anker PowerCore 10K is a compact and travel-friendly power bank with a 10,000mAh capacity, making it a solid choice for keeping your devices charged on the go. Thanks to Anker’s PowerIQ and VoltageBoost technologies, it offers fast charging up to 12W, which can quickly recharge smartphones like the iPhone or Samsung Galaxy. Its two main ports, USB-C and USB-A, provide good compatibility with a variety of devices, although it charges itself via Micro-USB, which is a bit outdated compared to USB-C input found in newer models.

The power bank includes Anker’s MultiProtect safety system, offering reliable protection against overcharging, short circuits, and temperature issues, which is important for safe everyday use. Its slim and lightweight design (weighing just 7.4 ounces) makes it easy to carry in a pocket or bag, perfect for travel or daily commuting. However, the absence of a USB-C charging cable in the box means you might need to buy your own, and the single USB-C output port limits simultaneous fast charging to one device at a time.

Providing around 2 full charges for an iPhone 12, this power bank may not be sufficient for heavy users or multiple device charging sessions. It is a dependable and well-built device suitable for those needing moderate fast charging in a portable package, especially if preferring something compact and durable without extra bulk.

The Belkin Portable Charger with 20,000 mAh capacity is a solid choice if you need to charge multiple devices on the go. It offers three ports—one USB-C and two USB-A—which means you can charge up to three devices at the same time, making it convenient if you carry both newer USB-C devices and older USB-A ones. The USB-C port supports Power Delivery at up to 15W shared between two devices, while each USB-A port can output up to 12W, so charging is reasonably fast but not the quickest compared to some newer chargers with higher wattage. The charger comes with a USB-C to USB-A cable, so it’s ready to use right away.

Safety is well covered here with overcharge protection and a two-year warranty, helping to keep your devices safe. In terms of size, it’s fairly compact and portable, weighing just over a pound and fitting easily in a bag. However, it’s not the smallest charger out there, so if you want something ultra-light, this might feel a bit bulky. Compatibility is broad, supporting major smartphones like iPhone 16, Samsung Galaxy S25, and Google Pixel 9, which makes it versatile. The built-in LED indicator is a helpful touch to keep track of the remaining power.

If you value charging several devices at once and want a dependable power bank with good safety features, this Belkin model is a practical pick, though if you need the fastest charging speeds available, there are faster options on the market.

The Belkin Portable Charger is a solid choice for anyone needing a compact and efficient power bank. It offers a 10,000mAh battery capacity, which can provide about 40 hours of extra phone life—good enough for daily use or short trips. Its three ports (one USB-C and two USB-A) allow you to charge multiple devices at the same time, which is convenient if you carry more than one gadget. The charger supports 15W fast charging, helping your devices refill their batteries faster than standard chargers, though it’s not the fastest on the market.

Compatibility is broad, covering iPhone, Samsung, and other USB-powered devices, so you won’t have to worry about your phone or tablet. Safety is well-covered, with rigorous tests ensuring reliable and secure charging. The power bank is also lightweight and slim, making it easy to carry around. One thing to keep in mind is that while 15W is decent for fast charging, some newer models offer higher wattage for even quicker charging. Also, it comes with only one short USB-C to USB-A cable, so you might need additional cables if you want to use all ports simultaneously.

This Belkin charger strikes a balance between portability, safety, and convenience for everyday users who want a dependable power boost on the go.
