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 325 Power Bank (PowerCore Essential 20K) is a strong choice if you need a reliable portable charger with a large capacity. Its 20,000mAh battery can recharge popular smartphones like the iPhone 15 about 3.6 times, which is enough for several days without access to a wall plug. It offers multiple ports: two USB-A, one USB-C that supports fast 15W charging both for input and output, and a Micro USB for flexible recharging options. This means you can charge two devices at once, which is handy when you have multiple gadgets. The power bank also includes Anker’s PowerIQ and VoltageBoost technology to ensure your devices charge safely and efficiently, even those that need very low power like wireless earbuds.

Its size and weight are reasonable for its capacity—about 6.2 x 2.9 x 0.8 inches and just over 13 ounces—making it portable but not pocket-friendly for all users. One downside is the charging time: it takes around 9 hours to fully recharge the power bank with a 15W charger or higher, so it’s not ideal if you want very quick turnaround. Also, it uses two internal batteries, which is common but means it is a bit bulkier than smaller capacity models.

This power bank is suitable for anyone looking for a dependable, high-capacity charger to keep multiple devices powered during travel or long days out, as long as you’re okay with its size and moderate recharge time.

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.
