10 Best Portable Power Chargers 2025 in the United States

The INIU Portable Charger is a great choice if you want a slim and lightweight power bank with solid capacity for everyday use. It packs 10,000mAh, which is enough to recharge most smartphones about two times, making it handy for short trips or daily backup power. One standout feature is how thin it is—only half an inch thick—and it weighs just under 9 ounces, so it fits comfortably in your pocket or bag without adding much bulk. It also supports 3A high-speed charging, which means it can charge devices like iPhones much faster than standard chargers. The USB-C port works both for charging the power bank itself and for charging other devices, which is convenient if you prefer using USB-C cables. Plus, there is an additional USB-A port, allowing you to charge up to two devices at once.

The built-in safety system protects your devices from overheating and overcharging, giving extra peace of mind. The small flashlight feature adds some utility in dark situations. On the downside, while the 10,000mAh capacity is good for many users, it might fall short for those wanting to charge tablets or multiple devices multiple times on longer trips. Also, the power bank does not support the newest ultra-fast charging standards, which could be a drawback if you have very high-power devices.

This charger suits travelers, daily commuters, or anyone wanting a reliable, easy-to-carry power bank with decent speed and safety features.

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.

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.

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.

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.

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.
