10 Best Portable Chargers 2025 in the United States

The INIU Portable Charger stands out in the portable charger category with its slim design and impressive capacity. At just 0.5 inches thick, it's remarkably easy to carry, making it ideal for travelers or anyone needing extra power on the go. With a capacity of 10,000mAh, this charger can recharge your iPhone multiple times and still have juice left for other devices like Samsung or AirPods, which is a definite plus for heavy users.

One of its standout features is the inclusion of a USB-C in and out port, which is rare among portable chargers. This allows you to charge the power bank and your devices using the same cable, simplifying your setup. Additionally, the 3A high-speed charging capability means your devices can get refueled quickly, which is great for those who are always in a hurry.

Safety is also a priority here, with a 15-layer SmartProtect system designed to prevent overheating and other risks during charging. This feature is reassuring for users concerned about the safety of their devices while charging. However, the INIU charger is lightweight and portable, its capacity may not be sufficient for users who need to charge multiple devices simultaneously or require more than one full charge for larger devices. Furthermore, although the design is sleek, the plastic build may not feel as premium as some competitors. Also, while it comes with a USB-A and a USB-C port for output, having just two output ports might not cater to users who need to charge multiple devices at once.

The INIU Portable Charger is a solid choice for those looking for a compact, efficient, and safe power bank, particularly for casual users and travelers. Those needing more than one or two charges for larger devices may want to consider alternatives with greater capacity and more output options.

This portable charger from Charmast offers a convenient and versatile solution with its 10000mAh capacity. Its standout feature is the built-in cables, meaning you don’t need to carry extra cords for different devices. With 6 outputs and 3 inputs, it's highly flexible and can charge up to six devices simultaneously, making it a great option for users with multiple gadgets, including iPhones, Androids, and tablets.

The super slim design, comparable to the size of a lighter cellphone, ensures easy portability, weighing only 0.55lb. The digital LED display is a handy feature that shows the remaining battery percentage accurately, removing any guesswork about when you need to recharge it. However, while the capacity is decent, it may not suffice for heavy usage or long trips without frequent recharges.

Additionally, the inclusion of various input options is convenient, but it may confuse some users who are looking for a straightforward charging method. The charger comes with a pouch and user manual, and the brand offers 18 months of support along with lifetime technical support, which is a reassuring aspect. This product is especially beneficial for frequent travelers or anyone who juggles multiple devices and prefers not to carry various charging cables.

The Anker Power Bank (PowerCore 10K) is a compact and lightweight portable charger with a 10,000mAh capacity, making it a great option for those who need a reliable power source on the go. Its slim design (5.99 × 2.81 × 0.61 inches) and light weight (8.6 oz) make it easy to carry in your bag or pocket. The charger comes with PowerIQ technology, which ensures high-speed charging (5V/3A) for devices like iPhones, iPads, and more.

The USB-C port supports both input and output, enhancing its versatility for quick charging and recharging. Additionally, the PowerCore 10K is durable, with a design that resists scratches and has been drop-tested from 3.2 ft for added toughness. The pack includes a USB-C cable, a welcome guide, and an 18-month warranty with friendly customer service.

It should be noted that while 10,000mAh is sufficient for a couple of charges on smaller devices, heavy users or those with higher-capacity devices may require more frequent recharging of the power bank. This product is particularly well-suited for travelers and daily commuters who need a compact, durable, and efficient charging solution.
