10 Best Portable Charger 2025 in the United States

The INIU Portable Charger is a slim and lightweight power bank with a capacity of 10000mAh. This means it can charge devices like the iPhone 8 around 3.6 times or the Samsung S22 about 1.8 times before needing a recharge itself. One of its standout features is its slim design, being only 0.5 inches thick, making it very portable and easy to carry in a pocket or bag.

It's equipped with both USB-C and USB-A ports, which is relatively rare (only 5% of power banks have USB-C input and output). This makes it versatile for charging different devices using USB-C cables directly. The 3A high-speed charging ensures that your devices can be charged quickly, up to 78% in just one hour for an iPhone. Safety is a priority with its 15-layer SmartProtect system, which prevents overheating and battery damage.

The package includes a USB-C cable, a travel pouch, and a user manual, along with a 3-year warranty and lifetime technical support from INIU. However, it's worth noting that while having a high capacity and fast charging, the power bank doesn't support wireless charging, which some users might find limiting. Additionally, the power bank includes convenient features like indicator lights and a built-in flashlight, making it practical for travel and everyday use.

The Anker Portable Charger with a 10,000mAh capacity offers a solid balance between power and portability. It can charge an iPhone 15 up to two times or provide nearly two full charges for a Samsung S24. This makes it a reliable choice for travel or daily use when you're on the go and need a quick power boost. The 30W fast charging technology is a standout feature, significantly reducing the time required to charge your devices compared to traditional chargers. For example, it can charge an iPhone 16 Pro Max to 50% in just 27 minutes.

Additionally, the built-in USB-C cable is designed to last, tested to withstand over 10,000 bends, which adds to its durability. Another plus is its bi-directional charging capability, allowing for both 30W output and 20W input, which means it can charge itself and your devices quickly. However, despite these strengths, the power bank does have some drawbacks. Weighing 7.7 ounces and measuring 4.32 x 2.58 x 0.98 inches, it is a bit bulkier compared to some ultra-compact models. This might be a consideration if you're looking for something extremely lightweight and minimalistic.

Moreover, while it includes a built-in USB-C cable, compatibility with non-USB-C devices might require you to carry additional cables. The Anker Portable Charger is ideal for users who need a dependable, fast-charging power bank with ample capacity for a variety of devices, although it might slightly weigh down your travel kit.

The Anker PowerCore 10K is a compact and lightweight portable charger with a 10,000mAh battery capacity, making it a solid choice for everyday use and travel. Its slim design (about 6 by 2.8 by 0.6 inches) and low weight (8.6 oz) mean it easily fits in a bag or pocket without adding much bulk. It offers two output ports: a USB-C port that works for both charging the power bank itself and charging your devices, plus a USB-A port for more flexibility.

The USB-C supports fast charging at 5V/3A, which helps devices like iPhones, iPads, and many Android phones recharge quicker. This charger can provide roughly two full charges for an iPhone 15 and nearly two charges for a Galaxy S23, which is enough for most day trips or short periods away from a power outlet. It’s also built to be tough, with scratch resistance and a drop test to ensure durability.

While the single USB-C input/output is convenient, having only two ports might limit charging multiple devices at once if you carry several gadgets. Also, while 10,000mAh is enough for everyday use, it may not be enough for longer trips or heavier charging needs like tablets or laptops. If you want a lightweight, reliable, and fast charger for phones and smaller devices, the Anker PowerCore 10K is a great pick.
