10 Best Portable Power Chargers 2025 in the United States

The Anker PowerCore 10K is a compact and lightweight portable charger with a 10,000mAh battery, making it a practical choice for everyday use and travel without adding much bulk. Its slim size and light weight (just 8.6 oz) mean it fits easily into a bag or pocket, perfect for people on the go. It offers fast charging thanks to PowerIQ technology and supports both input and output through a USB-C port, which helps you recharge the power bank quickly and also charge your devices efficiently. The additional USB-A port gives you a second option for charging devices, but having only two ports means you can't charge many devices at once. The output is 5V/3A, good for smartphones and tablets but might be slower for larger devices.

It’s also durable, having passed a 3.2 ft drop test, so it can handle everyday knocks. If you need a reliable, easy-to-carry charger mainly for phones and smaller devices, this PowerCore 10K covers those needs well. For charging multiple devices simultaneously or higher output power for bigger gadgets, you might want to look for a model with more ports or higher wattage.

This portable charger from Charmast stands out for its built-in cables, including three output cables covering iPhone, USB-C, and Micro USB devices, which means you don’t need to carry extra cords—ideal for travel and everyday use. It has a 10,000mAh capacity, enough to recharge most smartphones about two times, making it suitable for daily needs without being too bulky. With six output ports (including the built-in cables) and three different input options to recharge itself, it supports charging multiple devices at once and offers flexible recharging methods.

The slim and lightweight design (about the size of a cellphone and weighing just over half a pound) means it’s easy to carry in a bag or pocket. A handy digital LED display shows the exact remaining battery percentage, removing guesswork when planning your recharges. It supports fast charging, which helps your devices power up quicker than standard chargers. Compatibility is broad, covering most popular phones and tablets including Apple, Samsung, Google Pixel, and others using USB-C or Micro USB. The inclusion of a pouch and 18 months of support add extra value.

On the downside, while 10,000mAh is sufficient for daily use, it might fall short for heavy users needing multiple full charges or to power larger devices. Also, the product uses lithium polymer batteries, which is common but worth noting for those concerned about battery types. This charger is a solid choice for anyone looking for a versatile, easy-to-use power bank with built-in cables and fast charging, especially if you carry multiple devices with different connectors.

The Anker Laptop Power Bank stands out as a powerful and versatile option for users who need to charge multiple devices on the go. With a large 25,000mAh capacity, it can recharge laptops, phones, tablets, and more several times, making it ideal for long trips or busy days away from outlets. It features three USB-C ports, each delivering up to 100W of power, which means it can quickly charge power-hungry devices like MacBooks and also handle multiple devices at once without slowing down. Additionally, it offers a USB-A port and two built-in USB-C cables—one retractable and one that doubles as a strap—adding convenience and reducing the need to carry extra cords.

Despite its robust power, the device weighs about 1.3 pounds and measures around 6 x 2 x 2 inches, which is fairly portable but might feel a bit bulky for pocket carry. A key advantage is its fast recharge capability, reaching 30% power in just 20 minutes. It's airline-friendly with 90Wh capacity, fitting carry-on rules for air travel. The reliance on USB-C ports may be limiting if you have many older devices needing USB-A, though one USB-A port is included. Also, while the built-in cables are handy, their fixed length might not suit every charging situation.

This power bank is particularly well-suited for people who regularly need to power multiple high-demand devices, especially laptops, while traveling or working remotely, but casual users or those wanting something ultra-compact might find it more than they need.
