10 Best Portable Charger 2025 in the United States

The Anker Zolo Power Bank offers a substantial capacity of 20,000mAh, which is excellent for extended travel or long days out, allowing you to charge devices like the iPhone 15 up to four times. With 30W two-way fast charging, it can quickly charge your devices and recharge itself at 20W, making it very efficient.

The built-in 5.98-inch USB-C cable is a convenient feature, and its durability, tested to withstand over 10,000 bends, ensures long-term use. Enhanced safety measures with ActiveShield 2.0 technology monitor temperatures and adjust power output for safe charging, which is reassuring for users concerned about device safety. However, at 11.2 ounces, it is relatively heavy for a portable charger, which might be a drawback for those looking for something more lightweight.

The dimensions (4.72 x 2.9 x 1.24 inches) make it fairly compact, so it can still fit comfortably in bags or pockets. This power bank is ideal for users who need high capacity and efficient charging for various devices including iPhones, MacBooks, and Samsung Galaxy phones.

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.
