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 INIU Portable Charger offers a good balance of portability and power. With a capacity of 10000mAh, it can recharge an iPhone 8 up to 3.6 times or a Samsung S22 about 1.8 times. One of its standout features is its slim design, measuring only 0.5 inches thick, making it very easy to carry in a pocket or bag.

The charger is equipped with a USB-C port that supports both input and output, which is rare in the market, and includes two additional USB-A ports, providing versatility for charging multiple devices simultaneously. It also supports 3A high-speed charging, allowing for faster recharge times compared to standard 2.1A chargers. The safety features are robust with a 15-layer SmartProtect system to prevent overheating and battery damage.

On the downside, while the charger is lightweight at 7 ounces, it might still feel a bit heavy for some users who prioritize ultra-light travel gear. Additionally, it offers a flashlight feature which might be redundant for some users. Despite these minor drawbacks, the INIU Portable Charger is an excellent option for those seeking a reliable, high-capacity, and portable power solution.
