10 Best Portable Power Chargers 2025 in the United States

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 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.
